When the clock struck twelve on December 31, 2009, the calendar reset and a new year was upon us. Watching the Times Square Ball dropping in New York, the fireworks going off at Marina Bay in Singapore, the temples in Japan ringing their bells 108 times at midnight, it is a timely reminder for everyone to start afresh and look forward to the new year with zeal and renewed optimism.

The start of the year brings new hope like the cool crisp spring air blowing through. Like a bear waking up after a lengthy period of hibernation, the metalworking industry can begin the year in earnest especially after a heartening show of resilience in the stirring fightback shown in the backend of 2009.

In Metalex Thailand 2009, the exhibition floor was an epicentre of activity and the buzz has translated to tangible results for many who decided to participate. Many exhibitors have registered high number of enquiries during the show and have given the economy in Asia a major vote of confidence for 2010. Although some still have misgivings on the

performance of the economy and where it will go in 2010, the general mood is a positive one, one with hope.

Staying in Thailand, the automotive industry is set to drive up exports. With the industry dependent on machine tools and its auxiliary equipment, this is a well-lit route, which should see free flowing traffic.

Mov ing away from la nd transportation and taking to the skies, the aerospace industry in Singapore is looking to be on the ascendancy as the skies clear up after the storm of last year. The country is now seen as the most comprehensive maintenance, repair and overhaul (MRO) hub in Asia, according to a report from Channel NewsAsia. More than 100 international firms are operating in the island state, including Rolls Royce, which has set up a manufacturing base at the Seletar Aerospace Park.

A s we du st of f ou r fe st ive lethargy and put away our Christmas decorations, we can look forward to an exciting year ahead. Echoing the general belief on the exhibition floor at Metalex Thailand, the worse should be over.

Linde Wins Engineering & Gas Supply Contracts In Russia Munich, Germany: The Linde Group has won several contracts for plant engineering and gas supply projects in Russia. The combined value of these contracts is estimated in excess of €530 million (US$758 million).

Under the terms of these unrelated deals, the company is building two olefin plants for two chemical customers in Western Siberia. In addition, the company will be building an Air Separation Unit (ASU) to ensure the long-term on-site supply of industrial gases to a steel company in the Moscow region.

Linde-KCA-Dresden, member of the group, will construct a polypropylene plant with an annual capacity of 500,000 tonnes in Tobolsk, Western Siberia, for the plastics manufacturer Tobolsk-Polymer.

The group will also be planning and overseeing construction of a gas separation and ethylene plant in West-Siberian Novy Urengoy for the chemicals company Novy Urengoy Gas and Chemical Complex.

This project is worth around €47 million for the group.

The ethane cracker will have an annual capacity of around 420,000 tonnes of ethylene a year.

In addition, the group has closed a long-term agreement with the steel company ZAO ‘Kaluga Research and Production Electrometallurgical Plant’, to supply the company with industrial gases at its production site in Vorsino (80 km south-west of Moscow).

The group will construct an on-site air separation unit with an investment volume of €37 million for this project. The ASU will have a production capacity of 9,000 Nm3/h of gaseous oxygen and additional capacities for the production of liquefied gases to supply the merchant market, particularly in central Russia.

Unison Wins ‘Largest-Ever All-Electric Machine’ Order

Machining Stainless Steel?

Look no further The VA Range consists of…

Scarborough, UK: Unison has won an order from BAE Systems surface ships for a large tube-bending machine to support ongoing projects, including the construction of the Royal Navy’s Queen Elizabeth Class Aircraft Carriers. Capable of handling tube and pipe diameters up to 175 mm, the machine is expected to be the largest all-electric tube-bender ever built.

BAE Systems chose the company as its tube bending automation supplier because of the cost savings potential of an all-electric machine architecture.

Together, these technical advantages will allow BAE Systems to improve capability, capacity and efficiency. Energy saving was a further factor in securing the order. The machines consume some amount of energy when they are actually performing a bend - whereas a conventional hydraulically powered bender typically consumes energy continuously, in order to maintain the system’s hydraulic fluid at high pressure.

Tokyo, Japan: JFE Steel Corp’s number three blast furnace at the company’s West Japan Works (Kurashiki), will be blown in for a fourth campaign (operating cycle) beginning in mid-February 2010.

The cost of the project is approximately 30 billion yen (US$325 million).

Industries including automotives are expected to continue ordering high-end steel at relatively high levels. By restarting its blast furnace following the revamp, the company expects to capitalise on the growing demand from domestic and international customers, especially in Asia, who require stable supplies of high-end steel.

Going forward, the company intends to further optimise its blast furnace operational structure on a comprehensive, company-wide basis, including production efficiency, costs and other key factors.

The agreement is designed to maximise turbine availability and energy production across EC&R’s US installed base of GE wind turbines. In addition, the agreement reflects the companies’ shared goal of maintaining peak performance and reliability and building the world’s best running fleet.

“By teaming with GE on this agreement, we will have greater capability to control our O&M costs over the long term, which will help us cut our total operating costs,” said Steve Trenholm, CEO of E.ON Climate & Renewables North America. “In addition, the agreement ensures that our wind turbines will continue to operate at high availability and overall energy production.”

A single point of availability across E.ON’s fleet of 529 GE wind turbines can equate to more than 25,000 MW-hours of additional energy produced annually. That is enough electricity to power more than 2,600 average American homes for an entire year.

“We look forward to working with EC&R in continuing their commitment to the ongoing development of renewable energy,” said Victor Abate, VP - renewables for GE Power & Water. “This landmark agreement is the start of a long-term services relationship. With one of the industry’s largest fleets of installed wind turbines, we have accumulated the technology expertise and experience to help customers keep their fleets operating at optimum levels.”

GE’s 1.5-MW wind turbine is the world’s most widely deployed wind turbine, with more than 12,000 units now installed. According to the American Wind Energy Association, the wind turbines accounted for 43 percent of all new wind power capacity in the United States in 2008.

BP & CNPC To Expand Production From Iraq Oilfield

Lenox Wins Technology Innovation Award In China

London, UK: BP and China National Petroleum Corporation (CNPC) have signed a technical service contract with Iraq’s state-owned South Oil Company (SOC) to expand production from the Rumaila oilfield, near Basra in southern Iraq.

The signing follows BP’s successful bid for the contract with CNPC. The consortium led by BP (38 percent) with partners CNPC (37 percent) and the Iraq government’s representative State Oil Marketing Organisation (SOMO 25 percent), has agreed to nearly triple the Rumaila field’s output to almost 3 million barrels of oil a day (b/d), which would make it the world’s second largest producing oilfield.

The Rumaila Field Operating Organisation (ROO) will manage the rehabilitation and expansion project.

BP and its partners intend to use their reservoir management expertise to boost recovery and increase production from the Rumaila field, focussing initially on waterflood and gas reinjection optimisation.

Using Graphical System Design for

Tumor Treatment The Challenge: Designing, pro t o t y ping, and deploying the user inter face and control system for an FDA– approved, Class II medical device used to treat breast tumors in a less invasive and nearly painless procedure, while maintaining the design process within strict regulatory guidelines.

The Solution: Using the NI Compact RIO platform, NI LabVIEW RealTime, and the LabVIEW FPGA Module to develop a flexible and reliable GUI and control system under extreme time-to-market pressure to deliver a device that would dramatically reduce the emotional and physical discomfort of patients undergoing tumor treatment.

At Sanarus, a medical device start-up company, we developed plans for a potent ially revolutionary product that could change the way doctors treat benign tumors. With this device, doctors can eliminate tumors by freezing and killing them in an almost painless outpatient procedure, a dramatic change from the in-patient surgical solution or the “wait-andsee” approach used previously. With a well-executed design and development plan, we hoped to market a device that would have a huge impact on breast cancer treatment.

T he end resul t , the V isica2 Treatment Sys tem™ ( V 2), is an instrument intended for use in a doctor’s office or clinic. The procedure involves local anesthesia and a realtime, ultrasound-guided approach that is virtually painless. The treatment, which lasts 10 to 20 minutes, freezes and destroys targeted tissue through

LabVIEW FPGA was used to develop the control system and GUI for the Visica2 Treatment System.

Using the off-the-shelf CompactRIO platform, Sanarus was able to quickly develop a working prototype

an incision so small that it does not require stitches.

Time to Market Pressure We were tasked with developing a working prototype of the V2 system within four months to satisfy the product release schedule. In addition to fulfilling our commitment to our investors, we needed to meet marketplace demand and produce the V2 as soon as possible.

Writing firmware and designing a custom circuit board for the device would have been time-consuming, and any error at the firmware or software level could have created delays that would have threatened the entire project. Because V2 is a medical device, it must not have any software or firmware errors that could compromise system performance. If the device had failed the exhaustive testing required for our 510(k) submission, our entire project would have failed and the V2 would not have made it to market. Based on these requirements, we needed an extremely reliable development option for V2.

Speeding Development with Off-The-Shelf Hardware Sanarus invited a National Instruments field engineer to discuss possible solutions with us. We quickly realized that the CompactRIO was a viable solution for our needs because of its mix of programmability and integrated I/O development. We designed the prototype using CompactRIO to prove that the V2 would be developed reliably in a short period of time. A tradeoff table illustrated the differences between using CompactRIO and our own custom hardware. The payoff from using CompactRIO was apparent; while a custom solution would have taken months to develop, the NI solution took only weeks.

In addition, with custom firmware, “late game” changes would have required new and difficult revisions, but with the CompactRIO platform, we could revise our code if needed with

minimal effort. When we decided that the UI needed to be a touch panel PC instead of buttons and LEDs, we used the LabVIEW for Windows graphical programming environment to develop a UI for a PanelPC. We were able to simply manage communications between the GUI and the CompactRIO Real-Time controller using LabVIEW shared variables. We also met the new feature requests without causing delays in the development schedule because of the system flexibility.

We knew CompactRIO would pass EMC certification, because NI precertified the modules. This guaranteed that our prototype would not have to be redesigned if it failed EMC certification.

The final V2 system consists of a PanelPC that runs LabVIEW for Windows. This operates the user interface and sends commands to a CompactRIO system using LabVIEW Shared Variables. LabVIEW RealTime was used to implement a state machine on the CompactRIO Real-Time controller, and on the PID, LabVIEW Real-Time regulated loops to control the temperature of the tip of the probe.

This is done by providing control algorithms to a liquid nitrogen pump for cooling as well as a simple resistive heating element. The LabVIEW FPGA was used to manage the interfacing to the I/O signals necessary to control these devices.

In long-term studies, our technique is highly effective in destroying common tumors, and the V2 is now available at selected centers throughout the U.S. Thanks to NI, we quickly and efficiently developed an embedded control system with a user-friendly GUI for the V2 while maintaining the highest quality, and ultimately, ensuring the safety of our customers’ patients.

NI played a fundamental part in achieving our goals. Our product design, protot ype, and eventual deployment timelines were met because of the graphical system design platform from NI. With LabVIEW, we designed and coded our controller in house, then prototyped and deployed machines much quicker than we ever thought possible. In fact, our CEO called CompactRIO a key factor in the success of the Visica2 Treatment System™ project.

Green Light For Bombardier Trams With Energy Storage

Berlin, Germany: Rhein-Neckar-Verkehr (RNV) is set to commission the first six Variobahn type Bombardier trams at its Heidelberg site in Germany. These trams are the first to feature the commercial application of the Bombardier MITRAC energy saver, the energy storage system. With this system, vehicles require up to 30 percent less energy and are capable of catenaryfree operation.

“We will save about 93,000 kWh of electrical energy per vehicle each year. That also benefits our region due to lower emissions when generating electricity at the power station”, said Martin in der Beek, Chief Technical Officer of RNV. The energy storage system is part of the ECO4 portfolio of Bombardier Transportation, enabling rail vehicles to be operated in a particularly economical and energy-saving way.

It saves up to 30 percent energy and utilises an energy recovery system: three roof-mounted energy storage units use their capacitors to store the energy generated during braking, ready to release it again when accelerating or during operation.

The double-layer capacitors of the system store up to 3 kWh per vehicle. When starting up and accelerating, vehicles require a particularly large amount of electricity and put a significant burden on the power supply network. This is reduced by about 40 percent with the system, allowing the network to be utilised more cost effectively.

Thirteen more vehicles will be supplied in 2010 for Line 5 and sections in Mannheim. RNV has ordered a total of 19 light rail vehicles with the energy storage system. They will enter service by the end of 2010.

Fifty-five customers around the world have ordered 840 787s, making it the fastest-selling new commercial jetliner in history.

Airbus Final Assembly Line China Achieves 2009 Target

Sikorsky & Tata To Manufacture Aerospace Components

Toulouse, France: The Airbus A320 Family Final Assembly Line China (FALC) has achieved its 2009 target as the 11th A320 Family aircraft assembled by the FALC was delivered to Deer Air, an airline part of the HNA Group.

The first A320 assembled by the FALC was delivered to Sichuan Airlines via Dragon Aviation Leasing in June 2009. Since then, a total of five A320 and five A319 assembled by the FALC have been delivered and are now in operation with Sichuan Airlines, Deer Air, Shenzhen Airlines and China Eastern Airlines.

“We are very proud to have achieved our target in the first year of operation, on schedule and on quality.

When we started operations in August 2008, we had two challenges: deliver Airbus quality from Tianjin and ensure a smooth ramp up of production. Both objectives were reached. The success achieved in FALC is definitely a way forward for the continuous industrial cooperation between Airbus and China,” said Laurence Barron, Airbus China President.

Mumbai, India: Sikorsky Aircraft Corp and Tata Advanced Systems Limited (TASL) have signed an agreement creating a joint venture that will manufacture aerospace components for Sikorsky in India, including components for S-92 helicopter cabins.

The joint venture agreement builds upon a longterm contract signed in June 2009 for TASL to assemble Sikorsky S-92 helicopter cabins.

The cabin assembly contract signed in June 2009 has led to ongoing construction in Hyderabad, in the state of Andhra Pradesh, where TASL will assemble S-92 helicopter cabins starting in 2010. The joint venture will be positioned to manufacture components for other aerospace OEMs as well as detailed parts for the Sikorsky S-92 helicopter cabin.

It is expected that the joint venture operations will be housed in a second greenfield facility that will be constructed in Hyderabad, next to the cabin assembly building. Construction for the joint venture company’s facility is targeted for completion by 2011, with production beginning in late 2012.

Mining & Metals Industry Continues To React To A Challenging Environment

Boston, USA: The growth trend in the mining and metals industry that spurred demand for automation, instrumentation, and operational software came to a halt in the last quarter of 2008. The cause was the now well-known global financial crisis that led to a global recession, the likes of which had not been seen for over 30 years.

Through the first few months of 2008, demand for metals worldwide continued to grow. Emerging market demand was growing fastest as manufacturers in Asia and Eastern Europe increased production of industrial and consumer goods.

Now the situation is quite different. World demand for steel in the first quarter of 2009 has dropped by nearly 25 percent, causing major steel producers to see profits plummet. The reduced demand for iron and steel has led to a dramatic drop in both the demand and price for iron ore.

“With the global economic downturn as a backdrop, it is understandable that mining and metals companies have cut back the aggressive growth plans of pre2008. However, spending will still be needed in 2009 with stronger spending to begin in 2010 and beyond,” according to Analyst Dick Hill, ARC Advisory Group, the principal author of ‘Automation Expenditures in Mining and Metals Worldwide Outlook’.

Big Investments On Hold, But Growth Will Return The leading global mining and metals companies understand that, though it may seem counterintuitive 26

metalworking equipment news Jan-Feb 2010

in light of the current economic downturn, it is important not to under-invest even now. Certainly, capital outlays are required to maintain production levels at existing mining sites as well as metals processing facilities. The larger investments seen prior to the current downturn have been postponed, but will have to be made to keep up with global demand for minerals and metals.

Over the long term, demand will rise again, particularly in developing regions, and mining and metals prices will rise along with it. Indeed, over the short term, engineering and materials costs may go down as some more complex projects are put on hold, and steep drop in demand for finished goods helps to push down the prices for steel and other commodities.

The end result is a more favourable environment for investment than many might expect.

Asia & Latin America To Lead Growth Regionally, the highest growth rates will occur in Asia and Latin America. Asia’s share of sales will exceed 35 percent, and while Latin America will experience healthy growth over the forecast period, the region will still remain a relatively small portion of the overall market.

Despite the strong growth in developing regions, Europe, Middle East, and Africa will have the largest share of the market. North America’s demand for automation, instrumentation, and software solutions will drop below 22 percent of the world’s sales as its growth is expected to be the lowest of all four world regions.

Turning and milling continue to undergo new transformations to keep up with the winds of change.

By Michael E Neumann

T

urning and milling are two examples of subtractive process in metalworking.

A lthough there are competition or complementary processes like 3D printing, depending how you look at it, they remain a primary process for many.

Placing a single point cutting tool parallel to the surface of a rotating part is turning in its basic form. This process can be done manually, or by CNC. When turning, the metal is rotated and a cutting tool travels over two axes of motion, resulting in diameters and depths.

It can however be travelling on the outside of a work piece, giving birth to tubular components of various geometries.

Milling on the other hand, involves moving a workpiece against a moving cutter. The orientation of the spindle also gives rise to vertical and horizontal milling, the two basic forms. Like turning, this process is operated manually or by CNC.

New Requirements Mandate Changes In an increasingly competitive ma nufacturing env ironment where parts are getting smaller, tighter tolerances are imposed as well to place more emphasis on the accuracy of modern day turning and milling machines.

Three sectors, the aerospace, automotive and medical device manufacturers are arguably chiefly responsible for this push for higher technology. The drive for better fuel economy in aviation especially in long-range flight has certainly upped the ante for many designers or engineers alike as they try to produce the lightest possible part, putting tremendous demand for advance tooling and machine tools. With the Boeing 787 Dreamliner making its maiden flight, it heralded not only a new generation of commercial planes but also throws down a gauntlet to engineers to develop new generation of machine tools.

Elsewhere in the healthcare i n d u s t r y, t h e d e m a n d f o r prostheses has also place the onus firmly on producing 100 percent complying parts. For better or worse, the machine tool and tool manufacturers have to respond to this pressing need.

Meeting Challenges The Mori Seiki NV7000 improves the rigidity by increasing the width of guideways 2.4 times wider than the conventional machine. It offers better damping performance with the use of slideways in all axes.

The vertical machining centre also achieves an 18 percent larger work envelope than the conventional machine while reducing the floor space by 15 percent. Equipped with three spindle variations, it can meet a wide range of customers’ needs from high-speed to heavyduty cutting.

By incorporating a DDRT (Direct Drive Rotary Table), high-efficiency machining and simultaneous 4-axis machining are possible. This has

Case Study Red Bull Racing Milton Keynes

Leica Absolute Tracker gives Red Bull Racing wings

C

hris Charnley, Quality Manager at Red Bull Technology (the design and manufacturing part of Red Bull Racing), comes straight to the point: “We have no time for mistakes.” The manufacture of Formula 1 cars demands precision and the highest standards in the development and manufacture of vehicle components. “Basically in our business we are continuously developing prototypes,” says Charnley. During the racing season, the general shortage of time felt by Formula 1 racing teams builds up to extreme levels: Major modifications to the design to optimise the aerodynamics of the cars have to be completed in the period between two races – normally two weeks. “That’s what you call high pressure,” says Chris Charnley. “Working nights and weekends then becomes the rule. But we have a lot of fun doing it, especially when we see the success of our efforts in the race.”

Not just measuring – it has to be a “LeicaCheck”The range of applications for the Leica Absolute Tracker in the day-to-day development environment is wide and varied. Quality Engineer Mike Hughes is frequently contacted by the designers when they wish to check the dimensional integrity of a new component. “They come to us and ask not just if we could measure the part – they ask us for a ‘Leica-Check’. The measurement results from our four Leica Geosystems Laser Trackers are reliable and authoritative – and word has got around.”

Red Bull Technology measures the assembled racing cars as well as the individual components. Formula 1 is a sport, and sports have rules. The dimensions of the cars are strictly defined.

“Legality checks” are all part of the routine before every grand prix. Compliance with maximum and minimum limits is c o nfir m e d quickly and easily with the Leica

Andreas Petrosino Absolute Tracker and the Leica T-Probe. Jon Roberts, Metrology Specialist, describes his experience: “There are many critical points on a Formula 1 car. We check the wings on the front and rear, the overall width of the vehicle, even the position of the pedals. Everything must be perfect down to the finest detail. With the Leica T-Probe, the difficult-to-access areas are simply more points to measure.”

Hexagon Metrology: Global technology partner

If worst comes to worst, Hexagon Metrology has already proved its worth as a Innovation Partner to Red Bull Racing. If the Formula 1 Team’s metrology engineers have to carry out a particularly difficult measurement, Hexagon Metrology technical service staff are there offering moral and practical support – if necessary at a moment’s notice. The Hexagon Metrology Regional Service Centre in Milton Keynes is only a few miles from the Red Bull Racing and Red Bull Technology HQ. Even when the Formula 1 entourage sets off around the world, Red Bull Racing can depend on Hexagon Metrology’s global presence. The Red Bull Racing measuring system usually stays at home. For an event in Spain however, the racing engineers urgently needed an accurate measuring machine. One phone call was enough: Hexagon Metrology in Barcelona quickly made a Leica Absolute Tracker available.

Chris Charnley: “That’s partnership. Our contacts at Hexagon Metrology are fully integrated into our team.”

The machinery park at Red Bull Technology includes several product generations of Leica Geosystems Laser Trackers. These systems are in use at the Red Bull Racing wind tunnel at Bedford. During the aerodynamic tests, the Laser Tracker continuously analyses how the model vehicle deforms in the wind. In addition, Red Bull Technology uses DEA coordinate measuring machines and a third-party CMM that has been modified with a Hexagon Metrology retrofit package.

Leica Absolute Tracker: A brilliant all-purpose tool

Chris Charnley summarises: “The Leica Absolute Tracker is a brilliant all-purpose tool and without doubt one of our best investments. The speed of measurements justifies the investment by the time saved on component measurement. We are always discovering more uses for it. Accuracy, portability and reliability inspire the team. The Leica Absolute Tracker has played an important role in our many successes.”

he N u re mb e r g pla nt (Germany) of Siemens E n e r g y i s a s e r v i ce cent re for indu st r ia l steam turbines. Since as early as 2005 the company has been using 5-axis machines from the monoBlock series, including a dividing attachment developed by DMG, for its production of turbine blades and vanes for industrial steam turbines.

In addition, an automated manufacturing cell was developed in cooperation as a further stage in the optimisation of the process chain.

As a service centre for industrial steam turbines, the portfolio of the Nuremberg plant includes both the servicing, upgrading and repair of industrial steam turbines.

In addition, it reproduces the socalled foodprint turbines according to customer specifications making them comfortable in operating in power ranges up to 120 mW. One Of The Kind “No two turbines are the same, each one is unique, because constructive properties must be taken into consideration on the one side and on the other every turbine was and is built for a specific application,” says Klaus Blödel, the production manager in Nuremberg.

A trouble spot in the process chain is the in-house blade production, where all turbine blades and vanes are produced.

Hundreds of them eventually find their way into an industrial steam turbine. The blades generally consist of a root, blade and tip and are made of heat resistant materials that are difficult to machine.

The root and tip parts have a relatively simple design, but they must conform to high accuracy specifications so that both secure fitting and smooth running of the turbine is ensured when they are assembled. However, the blade itself, whose contours are dimensioned for optimum efficiency of the turbine, has complex free-

Efficient blade manufacturing is made easy with 5-axis technology. By Ralph Schiffler, for DMG formed surfaces that are subject to stringent requirements with regard to accuracy and surface quality.

The Fifth Dimension In Machining The experts in Nuremberg have been exploiting the possibilities of five-axis machining for years now, in order to cope with the complexity of the components plus the small batch numbers in their countless different versions.

Equipped with these machines (in combination with a purposebuilt div iding attachment w ith hydraulic- controlled counterbearing), the company can now carry out complete machining on one machine for any blade, no matter how complex its geometry might be, flexibly and with high precision from the solid without re-clamping.

“The possibilities offered by the

monoBlock machines, which enable us to mill under negative angles down to –30 deg, are essential for blade manufacture,” says Holger Meyer, team leader of mechanical production.

“Deckel Maho developed an NC 5-axis dividing attachment for our process, which allows a program-controlled adjustment of the clamping pressure. This dividing attachment plus the length of our workpieces meant that we then needed a relatively large working area in the X-axis.

Last but not least the accessibility of the working area, which allows the operator to set-up quickly and easily with no problem at all, is also apparent,” he adds.

It is clear that the stability and performance data of the machines were also convincing during machining of the demanding materials.

As reliability is proven, the experts mastered the processes decided within the framework of a pending capacity expansion to take steps forward in automation.

Automation In Machining T he a mbit ion to int ro duce automation might indeed seem surprising at first glance when you consider that the operation times for turbine blades and vanes are mostly over an hour and can even be anything up to four hours in some cases. The proportional wage costs could not have been the driving force in the considerations.

Jürgen Montag, head of blade production says: “As far as the employees were concerned, our primary interest was to relieve them from the tiring setup process and so put the existing know-how within the department to more efficient use. However, the decisive factor for us was to achieve a high degree of continuity and process

reliability by using automation, for example, to eliminate the error rate during manual feeding.”

He further explains: “Moreover, we achieve a higher rate of overall efficiency for the milling machine through robot automation, because the standardised processes result in fewer malfunctions. Finally, we were able to improve the process itself even more thanks to the transparency and repeatability, which also brought benefit for the sta nd-alone machine in retrospect.”

None of the three people we spoke to wanted to reveal specifica lly how the robotmanufacturing cell compared with the stand-alone machines.

However, they all clearly denied in unison any potential doubts as to the profitability of the automation and agreed that future investments were unlikely to include any orders for stand-alone machines. MEN Enquiry No. 1002

Profiting With Competitive Sustainable

Machining Technology

Sustainability has found its way to machining, increasing productivity and reducing cost at the same time.

By Liu Peiling, principal research engineer, SIMTech.

A

sia n meta lwork ing industr y is under increasing pressure from more stringent environmental legislation, depletion of raw materials, high energy cost, and falling machinist skill levels.

The metal cutting companies have generally been reluctant to implement new sustainable machining technologies – largely due to a common belief that high cost in implementation will reduce their competitiveness. This is not true for machining.

Profiting from sustainable machining technology is not only technologically possible with the pervasive application of low cost computing, but also make business sense in high mix and low volume production, when the machining profit margin is much smaller due to international competition.

The increased profits come from reduced operating costs, reduced material purchase and waste disposal costs, reduced water and energy consumption. Adopting su st a i nable ma nu fac t u r i n g practices offer metal machining companies of all sizes a costeffective route to improve their economic, environmental and social performance.

The competitive sustainable machining technology, which is a subset of sustainable machining

34

metalworking equipment news Jan-Feb 2010

technologies, focuses on replacing trial cut and manual training by virtual machining simulation, increasing productivity by high efficiency cutting, and reuse material by re-machining of used component.

Getting It Right Many manufactured components involve machining. For components, machining systems play a n important role in the product life cycle as the connection between design and the finished components. The time and cost of transition from specification to commercial birth may significantly affect the remaining phases of the product life cycle.

Furthermore, the productivity a nd t he re sponsivene ss of machining systems as well as the machined surface integrity are important factors affecting product quality. All these characteristics are critical outcomes of machining systems used in production.

There has been a continuous improvement in machine tools and machining systems to respond to the needs for better quality products at lower costs. Evolution from manual machine tools to Numerical Control (NC) and Computer Numerical Control (CNC) machine tools and introduction of various sensing and control improvements have

enabled machine tools to be more capable, effective, and productive over the last several decades.

Even after these improvements, machining systems still require long periods of trial and error to optimally produce a given new product design or component. They still require cryptic NC language to operate with limited knowledge of what they are producing or how well they are producing.

NC errors could destroy work pieces and even damage machine tools. One NC error could make the workpiece a waste and take days to rework and eat into profits. In small batch production, there is no time for trial and errors. Especially for High Speed Mach in ing ( H SM ), t he fa st

moving and expensive cutter can be easily broken. The dynamic machining load will greatly affect cutter life, geometry accuracy and surface finishing.

Cutting Down Time Wastage The ‘First Part Correct’ idea embodies much of the lean concept that we are attempting to achieve.

Tremendous waste in time, cost and resources have historically occurred in the transition from design to successful machining of the first detail part. In the time of high-mix low-volume production, there is no time for trial cut.

Virtual machining is a modelling process that realistically simulates the setting up and running of an actual machining operation. First, the user specifies the raw material shape from which the part will be cut.

Then, after selecting the cutter, the NC program automatically simulates the motion of the machine tool.

The programmer can watch the material removal process and see details of how each cut changes the in-process shape of the part. The NC simulation program is smart enough to detect problems such as fast move error and collision that could scrap the part, break the cutter, or crash the machine.

A ny error discovered by simulating software allows the NC programmer to immediately identify the offending NC code.

The problem can therefore be fixed during the NC programming phase so as to ensure an error-free code when it reaches the shop floor.

High Efficiency Machining Saves Energy The ‘energy efficient export initiative’, led by the German Federal Ministry of Economics, underlines the commercial importance for the efficient use of energy. Metal cutting companies have introduced measures to increase their energy efficiency, and energy cost is now a focal point. Significant savings have been gained through the use

Virtual machining is a modelling process that realistically simulates the setting up and running of an actual machining operation

of intelligent controlling toolkits.

Improving energy efficiency can be achieved in two steps, the monitoring of energy flows in factories and the analysis of energy use in individual production processes and systems. The optimisation of energy usage in production must go above the energy management if the goals of doubling total commercial energy productivity by the year 2020 compared with that recorded in the year 1990, are to be reached.

These optimisations include energy management and the controlling of energy coefficients, ie: tailored machining process planning and process implementation with consideration for the energy coefficients.

The current generation of tool condition monitors work from pre-set limits on various sensor values, including power levels. But spindle power, for example, can have normal excursions such as when the tool enters a corner cut.

Without any information about the cutting process, these tool condition monitors must act blind, leading to false error reports and/or missing true alarm conditions. The available tool condition monitors focus mainly on catastrophic events such as tool or tooth breakage.

Simulating Machining Operations The simulation of chip formation using the Finite-Element-Method (FEM) predicates the cutting force and chip thickness. In real

machining processes however, these pa rameters are interdependent and influence one a nother heav ily. Integ rated simulation, whereby the process-machine interaction is simulated, is therefore a further key technology for sustainable production in the future.

Tool chatter is the barrier for higher material removal rate and can damage machine tool spindle.

A certain combination of depth of cut and speed can incur selfexcited vibration of tooling system and generate cutter marks on the machined surface. Dynamic machining model and simulation can predicate best cutting speed and depth combination that will cut faster without chattering.

The simulation of machining operations offers the potential to fulfil the ecological, social and economic requirements of sustainability.

For example, the adjustment of the suitable feed rate in the milling of complex geometries from difficult to machine materials may be optimised t hrough simulation and so reduce the machining time by up to 40 percent. The resultant reduction in consumed resources allows savings in both costs and energy.

The machining model, simulation, and verification processes ensure that the NC programs sent to the shop are Jan-Feb 2010 metalworking equipment news

Re-Machining By Welding Why discard damaged components when you can re-machine them?

Most material and energy are wasted in manufacturing processes. These wastes can be saved through re-machining of the damaged component, where the damage can be repaired by welding or thermal spray.

In the aerospace i n d u s t r y, ove r h a u l of jet engine has been a profitable business wo r l dwi d e fo r a lo n g time. Nowadays even automotive industr y starts to re-manufacture many components, especially engine.

However, re-machining is a great challenge for CNC machining.

Getting Your Bearings The programming of most machining operations is based around knowing three geometries: the position of the workpiece

on the machine, the starting shape, and the final shape.

Re-machining techniques allow successful machining when some geometry is unknown, by predicative machining model and s i m u l a ti o n, u s i n g i n process measurement to close any information gaps.

They are being applied for an increasing number of applications in the manufacture and repair of large and complex components in the aerospace industry.

The most common case is that where the exac t position of the workpiece is unknown.

With larger components, such as aerospace s tr u c tu re s , a c hi evin g the correct position and orientation of the stock on the machine is a major challenge, taking many hours of checking and adjustment. It is often

easier to adjust the datum for the toolpaths to match the position of the workpiece, than it is to align the stock in exactly the desired position.

Machining ‘Blind’ Examples where the exact starting shape is unknown can result from near net s h a p e m a nu fa c tu r in g processes, like casting and forging, or from imprecise repair techniques, such as welding. During airframe manufacturing, a casting or forging raw stock is always created with process dependent shapes, such as draft angle and allowance.

The most challenging re-machining operations are those where the exact final shape of the component is unknown.

welding with metals that have to be milled to the warped geometry.

This can be the case when the damaged components geometry have been changed from their nominal CAD shape during service, for example, turbine blades that have been distorted by the high temperatures in aircraft engines.

Companies wanting to use re -machining processes understand t h a t t h ey te n d to b e much more complex a nd p ro c e s s - sp e cif ic than conventional NC programming.

As a result, most re machining projects will require specific skill and customisation work as par t of their implementation, where the skilled machinist plays a key role.

is virtually impossible. Manually inserting different feed rates for each changing condition is not practical.

An incorrect feed rate estimate can break the cutting tool, damage the fixture, or scrap the part.

Ty pica lly either a single conservative feed rate is used for an entire machining sequence, or a higher feed rate is used but with a very conservative machining strategy.

Both methods attempt to ensure that the cutter is not overloaded, but at the expense of very inefficient machining. Both of these strategies result in overly slow cutting speeds or light removal rates that waste time, increase costs, and prematurely wear cutters.

To addre ss this issue, a knowledge -based machining package essentially adds intelligence to the cutter. During the simulation, in-process geometrical model knows the exact depth, width, and angle of each cut because the software also knows the exact shape of the in-process material at every instant of the machining sequence.

It knows exactly how much material is removed by each cut segment, and the exact shape of the cutter contact with the material.

With this unique knowledge set, it determines the best feed rate for each cutting condition encountered, taking into account volume of material removed, chip load, and machine acceleration and deceleration requirements.

If desired, the software can also divide cuts into smaller segments and vary the feed rates as needed in order to maintain a consistent chip load or volume removal rate. It then creates a new NC program, with the same trajectory as the original, but with improved feed rates.

Saving Material Machining is a subtractive manufacturing process that a cutter removes chips from part surface until it reaches a designed profile.

material. Innovative design of raw material block can save a lot of material. For example, a stepped block can save almost one third of raw material.

The machining stock is the volume difference between the designed part geometry and raw material geometry, which may be a bar or block. Reducing the machining stock can save raw material. The minimum machining stock could be achieved through near net shape forming of the raw material, such as casting, forging, and welding.

Generative machining processes have experienced a significant upsurge in recent years. In the field of metallic materials, aluminium, high-speed steel and stainless steel can be first roughly formed into 3D complicated components using a direct laser sintering

process and then machined to a precise profile.

Moulds with novel geometries can, for example, be realised without the need to use conventional machining operations and small batch production can already be undertaken in a commercially viable manner.

In the medium-term, generative machining processes offer an alternative to the time intensive conventional processes with both economical and ecological advantages.

With respect to the protection of resources the generative technologies also offer potential benefits, such as the production of the necessary components onsite, meaning transportation and storage costs can be avoided.

Dörries Scharmann Technologie GmbH (DST) is one of the few European owned companies playing a leading roll in the worlds premier league of heavy-duty machine tools producers.

Precision, cost-effectiveness and reliability are the qualities in which the company, headquartered in Mönchengladbach/Germany, is claiming to lead this challenging business.

The advantage for customers is that machines can be configured to incorporate practically every type of chip-removal technology, such as drilling, milling, turning and grinding, all from a single source, and, if required, these can even be combined into a single machine.

DST offers a wide range of machine tools for drilling, turning, boring, milling and grinding of medium and large size components.

Its product range includes vertical turning lathes, horizontal machining centres, highspeed machining centres, machining centres in portal and gantr y design and vertical grinding machines. Today, DST manufactures products for the brands Dörries, Droop + Rein, Scharmann, Berthiez and Mecof. With roots dating back to over a hundred years ago, the company has become internationally renowned for the production of high quality machine tools and is accredited to ISO 9001.

DST is serving major industry sectors, including: - Aerospace - Oil and Gas - Power Generation - Marine Equipment Production - Large Diesel Engines - Mould + Die Machining Center DBF 630 T he pa r t icula rly cr ucial benef it of t he Scharmann Horizontal Machining Center DBF 630 is the capability of machining a complete unit in a single clamping. The specif ied concentricity and axial accuracy of between 5 and 6 µm is consistently achieved.

The turning, drilling and milling head of the DBF 630 is the special feature that sets this machine apart from others. The spindle head incorporates a CNC controlled U-axis which carries out all the point to point on-centre machining work, as well as the off-centre turning and facing operations. A second clamping may be required only in order to machine the 6th side. But the machining center delivers an unusually high rate of efficiency.

The working spindle aligns to the axis of the contour to be made. The U-axis slide with the

40

radially moving turning tool adjusts the turning diameter and the cutting depth. During the cutting process the tool rotates round the axis of the cylinderical surface being machined. Compensation weights integrated into the spindle head automatically compensate for the imbalance which would otherwise occur during the turning process.

For the drilling and milling processes, a 35 kW spindle operates at up to 3,500 rpm. The slide fixes the tools at the center setting. In the case of turning, maximum speeds of 1,200 rpm can be reached at a maximum torque of 1,700 Nm. Vertical Turning Center VC-V The concept of the VC-C machine line is based on Dörries vertical lathes, because most of the critical cutting operations involve turning.

The turning centres are fitted with extremely complex technology to enable efficient machining of the workpieces, many of which could be very large and heavy. The machines can also be configured with a boring and milling unit and a high precision C-axis in the table. In addition, they feature a rotary table that can be moved in the Y-axis to allow longitudinal milling. The 37 kW drive allows the users to carry out boring and milling operations. A pickup magazine provides u n iversal a nd a ngled milling heads. A n NCcont rol le d a ngle d d isc grinding head can likewise be fitted for particularly tricky machining tasks.

Metal Metal Injection Moulding:

Malleability

An innovative way for manufacturing metallic parts, MIM brings cost reduction and also new ways to approach certain materials. By Liang Chee Hoo, senior manager, technology, Advanced Materials Technologies.

I

njection moulding is a productive and widely used technique for shaping plastic. Until recent times, injection moulding was only applied to polymers that melt on heating. The technique cannot be applied to shape metals, which have higher strength, stiffness and operating temperature.

Shaping of metals with 2-D geometry was traditionally done by applying powder metallurgy.

It is also known as pressed and sinter method.

Dawn Of A New Era Metal Injection Moulding (MIM) uses the shaping advantage of injection moulding but is applicable to metal. This process combines a small quantity of polymer with metal powder to form feedstock that can be moulded.

The moulding process allows the metal-polymer feedstock to

42

take the shape of a mould. After shaping, the polymeric binder is then extracted and the formed shape is sintered to achieve neartheoretical density.

Figure 1 shows a flow chart for the MIM process. It starts by mixing selected metal powders and binders. The metal powder usually has a small particle size between 3 to 20 um to aid sintering. These powders may come with different shape, spherical or irregular.

Ga s atomised a nd water atomised powder are the most common powder used in MIM process. The binder is usually based on a common thermoplastic such as wax or polyethylene, but cellulose, gels, water, and various inorganic substances are also in used. Usually, the binder system consists of two or more components. Typical binder content is approximately 40 volume percent of the mixture.

binder will form the feedstock.

Mixing process can be done by using a sigma/planetary mixer or a twin-screw extruder. A twin-screw extruder is always preferred as it provides feedstock with better homogeneity.

Quality of the feedstock is the most crucial determining factor in obtaining quality MIM part. The homogeneity and viscosity of the feedstock are the parameters to be controlled carefully during the mixing process.

MIM 101 The moulding process is the same process as per plastic injection moulding. Dependent on several p a r a m e te r s , t h e m o u l d i n g pressures are typically 600 bar or more. Pressure is maintained on the feedstock during cooling until the gate freezes to reduce formation of sink marks and shrinkage voids. After cooling in the die/mould, the component is ejected and the cycle repeated.

After the injection process, the shape of the component is formed.

The binder had served its purpose and it needs to be removed. The process of removing the binder is termed debinding. A wide array of options exists for binder extraction.

Thermal debinding is the easiest

to envision. The component is slowly heated to decompose the binder. Many variations exist, and the most popular alternative is to immerse the component in a solvent that dissolves some binder, leaving some polymer behind to hold the component in place.

The remaining polymer is then thermally extracted during the second stage thermal debinding process or part of sintering cycle.

Another popular option involves catalytic phase erosion of the binder. The debound part is highly porous and brittle in nature.

The next step is sintering, which can be incorporated directly into a thermal debinding cycle. Sintering process involves firing the debound component to a temperature close to the melting point of the metal.

Sintering bonds the particles together, leading to densification and therefore causing the shrinkage of the components. The shrinkage is within the range of 12 to 18 percent.

Often, sintering serves the dual role of densification and chemical homogenisation. In the latter role, mixed powders (mechanically blended) are moulded and sintering causes them to form homogeneous alloys by long-range atomic motion.

Usually sintering shrinkage is uniform and isotropic, so the moulded component is oversized to deliver the desired final dimensions.

The process is always performed 44

A magnetic valve body (Figure 3) is a good illustration of MIM’s capability to integrate different components into a single joint body.

Prior to the use of MIM to fabricate this magnetic valve body, the body is actually made up of four single pieces; two powder metallurgy parts, a turned part, and a machined part.

Figure 3: A magnetic valve body These four parts are then welded together is a good illustration of MIM’s to form the magnetic valve body. Functional, capability to integrate different by using MIM, the magnetic flux leakage had components into a single joint body been reduced and therefore the performance of the valve is enhanced. Besides the improvement in function, the cost of manufacturing the body had been reduced as well. The saving is estimated in the range of 30 to 50 percent.

Case Study 2

Bi-Materials Injection Moulding Another application of the MIM is bi-materials injection moulding.

The component is made up of two materials, a non-magnetic ring and a magnetic disc. As these two materials have different property in nature, it cannot be process together through the conventional technique.

Figure 4: Another Without using the MIM process, the application of the MIM is bimaterials injection moulding outer ring needs to be made through powder metallurgy, and the inner disc can be machined or made through powder metallurgy.

The two pieces are then welded together to form the integrated component.

However, by using the bi-materials MIM process, the two materials can be integrated during the injection process. All subsequent process, debinding and sintering, can be carried out together. Through this, the cost saving is achieved as it reduced the cost of fabricating two components and the welding process.

Case Study 3

Undercut MIM is sometimes selected to create the ‘impossible feature’, ie: undercut, in injection moulding process. These Figure 5: A complex undercut feature undercut features cannot be moulded made possible with the application of through injection moulding process because In-coring the insert or the slider cannot be retracted after the formation process.

With the used of In-coring technology, these features are made possible. Figure 5 depicts a component with intricate under channels. By applying the technology, the internal channels are formed by using removable polymer, followed by MIM process.

Once the green body of the part is formed, the polymer will be removed through chemical and thermal method. The difficulties in this technology are the forming of the undercut features without distortion, and the removing of the polymers without cracking and disfiguring the internal surface.

in a protective atmosphere or vacuum at a peak temperature that causes rapid elimination of pores previously filled with binder.

For steels and stainless steel, the sintering temperatures are in the range of 1,100 to 1,400 deg.

Injecting Value M I M ha s some b e ne f it s a s co mp a re d to co nve nt io n a l metal forming methods. The key benefits are materials flexibility, low cost production, shape complexity, superior properties, and tight tolerances.

It is able to process a large pool of materials. Most common material used in MIM is stainless steel, such as 316L, 17-4PH, 440C. Other materials that can be processed by MIM include, soft magnetic materials, low expansion alloys, corrosion resistance alloys, hard metals, high electrical conductive metal, such as

copper and tungsten copper.

Get In Shape Certain shapes required by the components are almost impossible to produce without using MIM. Figure 2 depicts a set of hinges components used in mobile phone.

If the same components were to be machined, the cost may be ballooned by >20 times.

All the complexity of the parts produced by MIM can be trapped within the mould design. As long as the complex shape is feasible in the tooling, MIM will be able to produce the components. The component produced by this method has good properties.

Firstly, the powder used by MIM is very fine (as compared to powder metallurgy). The resulting grain size is much finer and therefore giving rise to superior strength and ductility.

Secondly, the density of the MIM

components is generally more than 98 percent of the theoretical density.

Metal components with this level of densification will have materials properties closed to the bar stock.

MIM components have good surface finish. A roughness of less than 1.0 um Ra can be achieved.

The components produced by MIM have a general tolerance of 0.3 to 0.5 percent. At this tolerance level, the repeatability of the process is guaranteed.

The utilisation of MIM process opens up design freedom in manufacturing and engineering.

This freedom may seem to violate lots of design rules given in the textbook or from the design school; however, technology should progress with non-stop exploring and challenging of the ‘impossible’.

sensors follow the technical standards without failure detection (Figure 1).

One failure caused by either cross or short circuit will never be detected by the sensor itself.

In a worst-case scenario, this malfunction would not be detected before a real situation of a hazardous movement in the machine area takes place. The probability of accidents can be reduced tremendously by self controlled safety products of type 4 and 2.

Safety In Presses S t a n d a r d s (e g : E U: E N 6 9 2 mechanical press, EN693 hydraulic press) define the performance level sensors must fulfil for press applications. In Europe and the US, we traditionally see type 4 safety light curtains in press applications.

Generally, there is a global trend to safety standards accompanied by official controls.

Safety standards for safety light curtains (EU: EN61496) for example define the safety concept (type 4 or type 2), the optical characteristic and their reliability under environmental conditions.

Unlike safety sensors, non-safe

Types Of Sensors Type 2 products of the first generation followed a single str ucture combined w ith a controller for an external test to detect a failure during each test cycle (Figure 2). But today’s type 2 safety light curtain comes with the capability of a self check.

The benefit for the customer is that he need not worry about the safety relevant definition of the controller’s test rate.

The basis for this product concept is a watchdog mechanism that checks regularly the correct optical function and the processor.

The integration of 2 Output Signal Switching Devices (OSSD) is identical to a type 4 safety light curtain.

Advantage of the redundant integration of 2 OSSD’s in the controller is: should one output fail there is still one line to stop the machine. External Device Monitoring ( EDM ), a sa fety function, makes sure that a defect output signal will be detected immediately. The principle of this monitor is based on an inverse signal switch of the two outputs and the EDM signal line within a defined time frame (eg: 300ms).

The difference of a type 2 sensor with a type 4 sensor is based on the safety concept which one internal failure from the device will not lead to a situation where it affects the operational safety of the process. Reason is the principle of redundancy for the

electronic structure (Figure 3).

The other difference is the optical characteristic. It has narrower aperture angle (2.5 deg) compared to a type 2 (5 deg) version. That value has the advantage that the distance to beam reflecting surfaces (‘mirrors’) can be decreased to a minimum. Especially for small machines this feature is important for a compact machine design.

Non safe sensors do not have these limitations of the aperture angle. In a press application, the probability of such a curtain will not switch off the process in case of an interrupted beam is high because of the reflecting surface of the press.

Environmental Conditions The standards for the environmental conditions like EMC (eg: EU: EN61496-1) and vibration/ shock define the minimum values for safety light curtains. To keep the EMC values it is recommended to use a separated +24V power supply unit for the control cabinet and the power section should be physically separated from the control section.

Vibration/shock tests show that press applications are different.

Depending on the machine type (mechanic press, hydraulic press), the ground floor and the row material measurements show that strains vary tremendously.

On site measurements on mechanical C-frame presses eg: show frequencies over 120 Hz and accelerations with typical values of 20 g with peaks up to 120 g. Dampers are a standard solution to reduce these extreme values that electronic devices show.

Additional activities are the weak point analysis to optimise a product to this application.

A lab orator y v ibrat ion (Figure 4) and shock test simulates the conditions on site. After de-assembling the curtain the sensitive parts will be analysed.

Adequate changes of the product concept eliminate these sources for failure step by step. This process 48

of evolution is the base to get a reliable product under tough environmental conditions.

Protecting The Sensor The final design for such a heavyduty sensor is the housing. To reduce the impact of heav y mechanical strokes on the housing, nothing is better than a full body rubber protection. Damaged houses and scratches are history.

A typical machine in Asian markets is the C frame press (see main graphic). The position of the safety light curtain is not protected

by the machine frame. The rubber bumper is here the right accessory for that application.

The construction of the rotary L-shaped mounting brackets with light curtains is more sensitive to vibration than the closed construction of a machine frame. A combination of adequate dampers with an application proved safety light curtains are the right decision for high machine availability and also to avoid unnecessary after service costs.

Transforming Your

Into A

The ability to carry out on-machine measurements has benefits that go beyond financial savings. By Ettore Chiosi, product manager, Marposs SpA Difficulty: Measuring on-machine parts

Solution: I n s t a l l i n g m e a s u r e m e n t s o f t wa r e , turning machining or milling machines into a virtual CMM

Conclusion: Savings in machining cycle times

C

+C Mecca nica wa s established in Tuscany ( Ita ly) a s a shop of precision mechanical engineering. With their core business in manufacturing of moulds for thermoplastics, they rely on the available machine tool capacity consisting of machining centres with 3, 4 and 5 axes, NC lathes, grinders, CMM and CAD/ CAM software.

In 2005 the owners, driven by their passion for motorcycles, decided to diversify the production, starting projecting and making aftermarket accessories for Ducati and Aprilia motorcycles, made of ergal, titanium and obtained from a solid body.

A Typical Production Workflow Valerio Chiosi, owner of the company, explains how a new product is generated. The workflow starts with a scanning of the original part using a CMM. This supplies all the dimensions necessary for the CAD modelling stage in which technical aesthetical solutions are

50

metalworking equipment news Jan-Feb 2010

studied for any type of product.

The mathematical model is transferred to the CAM to formulate the machining strategies. Then the post-processed program is loaded in machine and machining is started.

Range Of Parts Measured These accessories such as sprocket cases, clutch cases, adjustable rear set kits and number plate holders, have sculptured surfaces and are fitted on the motorcycle where there are very precise housings and drilling planes. It is necessary to quickly check whether the dimensional requirements are met before proceeding with the finishing stage.

“The need for on-machine measurement was essential for a quick check of sculptured surfaces.

Moreover, as these components are quite structured, measurements on the CMM involved very difficult

fixturing and long times for realignment when returned to the machining centre. With Marposs’ 3DSI, we shortened the reworking times, since we can check the consistency between the CAD model and the machined part instantaneously,” says Mr Chiosi.

Software Solution Actually, the problem was solved by the company with the acquisition at the end of 2006, of the measurement software. It was combined with a Hermle C 800 U machining centre equipped with optical spindle probe OP32 for 3D measurements that has optimum spatial isotropy and unidirectional repeatability of 1μ (2Sigma).

“Now we are working with a higher degree of safety than before. Since the calibration is automatically entrusted to the software, each operator is free from errors and his responsibilities

Comparison made between the CMM and measuring software revealed a perfect overlapping of data

lightened. Measurements to be performed are already set by the 3DSI station user, who programs and safely simulates the measurement path just by clicking the mouse. The percentage of scrap was reduced as the finish machining begins only after evaluating the reports generated by the software following the rough finish or semi-finish stage,” he says.

“The introduction of the Tool Offset Feedback function in the software enables us to set, for each tool, a stock thickness in length and radius and protects us from errors in the interpretation of the measurement results,” he adds.

The initial skepticism at the purchase of the software program was conquered as soon as the company realised the versatility of the software.

This solution allowed the Italian company to avoid buying a new CMM as Mr Chiosi discloses before deciding to buy the 3D software.

A compa rison wa s made between the measurement output generated by the CMM and the output generated by 3DSI. The result was a perfect overlapping of data, with correlation in the order of 3 - 5μ, and 2μ repeatability.

Saving Time & Money In short, the owner quantifies a 20 percent saving in the machining cycle time of an individual item.

“We are enthusiastic about this software,” comments Mr Chiosi.

“Since we had already been using part-probing successfully for many years, and with the last machining centre bought, a Mazak Mould Maker 2500, we implemented the 3D measurement software combined with radio

spindle probe WRS,” he adds.

The introduction of the software in the product cycle, despite the high degree of complexity of these items, reduced the time to market, allowing substantial savings in time and money.

Magic Touch The

Combining the scanning systems with intelligent controllers allow better performance of measuring probes under difficult conditions. By Dietrich Imkamp, head of product management (bridge-type machines) and Karl Schepperle, head of sensor development, Carl Zeiss

T

he DIN EN ISO 10360 1 sta ndard describes probes as touch p r o b e s y s te m s . T h e standard differentiates between ‘touchtrigger’ and ‘scanning’ systems depending on the type of measuring point acquisition.

Touch-trigger systems record the measuring point at the moment of contact through a mechanical switch or through an electrical pulse transformer element, eg: a piezo sensor or wire strain gages.

A scanning system on the other hand, captures the deflection of the probe system when contact is made with a workpiece surface utilising the integrated measuring system, and determines the deflection. It is used to correct the measuring point coordinates delivered by the measuring system of the axes of motion (Figure 1).

A Probe For Difficult Environments The Variable Accurate Scanning Technology (VAST) scanning systems use the ‘sliding determination of mean values’ procedure in conjunction with the Zeiss intelligent scanning controller during measuring point acquisition. During this process, the measuring machine is stopped after it registers a probe pulse due to the deflection of the probe.

The system then check s whether the sum signal from probe 52

metalworking equipment news Jan-Feb 2010

deflection and positional data of measuring machine axes remain constant. A probing point is only accepted if the signal remains constant within a short interval.

Mean value from the deflection signals recorded during this period is used to correct the probe deflection. Sliding determination of mean values automatically dampens noise pulses caused by vibrations, for example.

As a result, the probes of the VAST line are less affected by electromagnetic interferences than a touch-trigger probe, which have an effect the moment contact is made with the workpiece. This technology permits the reliable use of probes under difficult environmental conditions and reduces sensitivity to outliers.

Passive & Active Scanning Systems Scanning systems are distinguished Linearity range of the mechanical springs

Measuring Force

by the type of measuring force generation. With a passive system, the measuring force is generated by a mechanical spring. An active system consists of a linear drive that generates the probing force electrically. This is also known as an ‘electrical spring’. The use of electrical springs enables the operator to set measuring force over a large force range, largely independent of the deflection.

This permits a larger measuring range, which is required for a high scanning speed.

Measuring range of a passive system is limited by the linearity range of the mechanical springs in which the deflection and the force are proportional. It is two to four times smaller on a passive system than an active system.

It is important not to confuse the measuring range with the deflection range, which represents the mechanical range of motion of Figure 1: Passive and active scanning

the probe and is usually larger than the measuring range. As such, it is necessary to ensure that the probe does not move directly against its mechanical stop and trigger an emergency stop following a slight collision, for example.

Active Scanning & Self-Centring Probing As already shown, active systems allow higher scanning speeds.

Scanning speeds of up to 300 mm/s with the VAST gold probe are possible together with procedures to correct the dynamic bending of the device structure and the compensation for centrifugal force. This technology, called the Navigator, achieves the parameters for scanning performance in accordance with DIN EN ISO 103604 in less than 30 seconds.

Scanning performance of this technology can be utilised for all stylus configurations used in everyday measuring operations (s e e m a i n p i c t u r e). O t h e r manufacturers specify scanning speeds higher than 300 mm/s, but these are only available for certain applications and only for one stylus in the axis direction of the sensor. The actual existing flexibility of a CMM is not always available (see main picture).

Large measuring range and the better probe force regulation of active systems have also proven to be advantageous with selfcentring probing. Self-centring probing is a procedure in which the stylus is placed in a largely spherical or cylindrical bore which is smaller than the diameter of the stylus tip.

Probing occurs in the direction of the axis and perpendicular to this direction at the same time. In doing so, the stylus centres itself in a way that the position of this bore can be determined. To begin the centring process, the stylus must be positioned so exactly that it is located within its measuring range during probing.

Figure 2: Utilisation of measuring range with active fixed probe compared to articulating probe holder

Therefore, active systems can use their larger measuring range to compensate for deviations during positioning of the stylus in front of the bore. During the centring process, the better probe force regulation of the active system leads to exact centring of the stylus at the lowest point.

With passive systems, the centring process can be halted as a result of friction before the lowest point is reached. In such cases, this point is not reached and the measuring result is inaccurate. The effect also applies to self-centring scanning.

Articulating Probe Holder There are applications in which many features must be measured at very different angles (eg: metal parts). In such cases, it is advantageous to mount the probe to an articulating probe holder, allowing you to avoid a variety of stylus configurations.

The overall size of an active probe that is required to generate the probe force prevents the use of an articulating probe holder. A passive probe system that utilises only one mechanical spring, however, can be so small and lightweight that it can be mounted to an articulating probe holder.

Characteristic of a small passive probe system intended for attachment to an articulating probe holder is the lacking stylus counterweight.

As a result, these systems are only suitable for very light and, compared to active systems, short styli. The mounted stylus deflects the measuring force spring with its own weight, further reducing the small measuring range of a passive sensor. This effect can be somewhat minimised with modules of varying spring stiffness for different stylus lengths.

Effective measuring range with fixed probe

Effective measuring range with articulating probe holder

Limitations Of The Probe Holder Even if the use of an articulating probe holder enables you to avoid the many different stylus configurations, it should not be overestimated. There are several features that cannot be reached by an articulating probe holder.

Suitable stylus configurations on an active probe enable the operator to reach almost any feature as illustrated in the ‘all sides’ measuring task (see main picture).

This also illustrates how the use of an active fixed probe and a probe on an articulating probe holder affects the available measuring range (Figure 2).

As it is possible to approach the workpiece directly with a properly designed stylus, the active fixed probe requires a considerably smaller measuring range.

Furthermore, you must consider that the precise determination of positional deviation with the use of an articulating probe holder often requires a rotating or swiveling motion as the workpiece must be measured from different sides.

This motion generates additional measuring uncertainty as a result of the limited reproducibility of the articulating probe holder. This effect does not exist with an active probe with a T stylus configuration.

apid prototyping was a game - changing innovation for industrial designers when it was introduced two decades ago.

Previously, prototypes would be constructed from wood or metal in woodwork or machine shops. The process took weeks or months and the cost was often so prohibitive that designers skipped prototypes entirely and went directly from CAD to tooling. Often this meant that design flaws were not identified until manufacturing began, leading to expensive re-work and lost time.

Rapid prototyping technology has progressed significantly over the years improving on both the cost and quality fronts. Circa 2000, Objet Geometries introduced a jetting process of photopolymer resin in ultra-thin individual layers that builds models. The resin is simultaneously cured with a UV light during the layering process. It is an approach that allows for printing of several materials including flexible, rubberlike material and composite Digital Materials.

So why should you consider using 3D printing technology as part of your product development

To Product Life process? Objet surveyed its base of users from various markets including consumer goods, consumer electronics, medical device, education, research, entertainment and others, why they made the investment, and based on their responses crafted the top five reasons to integrate 3D printing into product development lifecycle.

Fast Prototyping 3D printing – particularly when done in-house – enables design teams to quickly produce a highquality, realistic prototype with moving parts, at relatively low cost when compared to other methods such as machining or outsourcing. This means teams can use prototyping on projects where it was not feasible in the past due to time or cost considerations.

“We needed a faster, more streamlined system: one that would let us do the engineering, development and production of clinical trial-ready devices in-

Improved design, timesavings and the ability to detect design flaws are just a few reasons to integrate 3D printing into product development lifecycle.

By Winnie Chu, channel and marketing manager, Objet Geometries Asia Pacific house. We had heard about rapid prototyping and were very excited about seeing how it could help us,” says Andre A DiMino, vice chairman of the board, executive VP and chief technical officer, Ivivi Technologies.

The integration of the Eden350 into the product development and production cycle at the company has been a success, yielding a positive return on investment in less than one year.

“We’ve cut an average of five to six weeks off the clinical trial device production process,” he adds.

Improved Design & Manufacturability The ability to quickly produce real working prototypes that teams can see and touch helps bridge the gap between the virtual CAD design and the final product. Design and manufacturing engineers can use these prototypes as a tool to better communicate how a design looks, feels, and operates allowing for the product design

to integrate with manufacturing at a n e a rl ie r st a ge i n t he development lifecycle.

Brian McLaughlin from Orchid Design, a division of Orchid Orthopedic Solutions says: “Often, something the designer sees on a rapid prototype – such as an undercut, or some other area of difficulty – will cause them to tweak the design before it goes to the customer or to machining. Or, a customer will say: ‘You created it just as I described, but now that I see it, I think we need to change X, Y or Z.’ 3D printing has definitely had a major impact on the quality and manufacturability of our designs.”

Field Testing More prototyping means more opportunity to evaluate whether or not a part will function as intended.

Prototypes allow designers to catch potential flaws before incurring the exponentially higher costs of re-tooling and rework, reducing some of the risk of introducing new products.

Shawn Greene from Fender Musical Instruments describes a recent project to develop a light-up front panel for an amplifier.

Using 3D printing, Mr Greene produced prototypes of the panel using a clear material, tested it with different types of lights and discovered that light did not deflect the way they thought it would.

“We had to adjust the design to make it work,” says Mr Greene. “In the past, we would not have done a prototype for that kind of part because it would have taken too long and cost too much money. So by the time we noticed that problem we would have already paid for tooling, and then we would have had to pay for amendments for the tool. The ability to rapid prototype in house saved us a fortune on that project,” he adds.

Improve Customer Satisfaction 3D printing can help improve

satisfaction for both internal and external customers. Designers using 3D printing have the ability to quickly produce realistic prototypes for internal decision makers, as well as external clients.

Having the ability to touch a real world concept, combined with testing functionality allows all constituents of the design and manufacturing process to make better product decisions. The bottom line, 3D printing helps organisations get better products to market faster than ever before.

“Frequently during a project, clients request design changes or wonder how particular changes may impact the overall aesthetic,” says Piet Meijs, R iet veld Architects. “Our Objet system lets us create a whole new model right away,” he adds.

Seeing Is Believing Design is both an art and a science that starts with imagination. 3D printing helps quickly transform something imagined into something that can be seen and touched.

Prototypes are often used to help sell new concepts, so the more realistic the prototype, the better.

Cost and time savings are the primary drivers for incorporating

3D printing into the product de ve lop m e nt pro ce s s. Bu t for some organisations, other factors influence the need for inhouse technology.

The ability to drive revenue – pertaining primarily to service bureaus – by offering 3D printing services or use the services as a way to lure customers into giving them ancillary business such as manufacturing.

Organisations oftentimes weigh the need for in-house technology against the efficiencies of outsourcing. A typical maturity curve is to start off with outsourcing, and then bring it ‘in house’ as the volume of projects grows.

Many have realised that an in-house solution has significant additional benefits like the ability to protect the confidentiality of their designs. Customers have also found that the 3D printing system can be useful for many different applications some of which were originally unexpected. Having this technology at their fingertips gives them the freedom they need to be more creative and efficient with their designs.

Machining For

MEDTEC

Manufacturing parts for medical devices is literally a matter of life and death, placing utmost importance on accuracy.

By Gerald Musy, service manager, Tornos Asia and Philippe Charles, market segment manager (MEDTEC), Tornos.

T

he medical devices market is in full ex pa nsion.

It sailed through the worldwide economic crisis without much scare, showing its ‘recession proof’ characteristics and at the same time attracting t h e p a r t s m a n u f a c t u r e r ’s attention. An increasing number of subcontractors are having a closer look at equipment and processes that could allow them to grab a share of this lucrative market.

The reasons for this healthy growth are mainly demographic.

An aging population combined with a more affordable choice of medical treatments are fuelling it. Patients get implants younger thanks to early disease detection, resurfacing technology for hip implants and preventive surgery. Medical tourism in Asian countries such as Thailand, Malaysia and India provide more reasonably priced treatments and health insurances are becoming more popular.

The medical devices industry,

58

metalworking equipment news Jan-Feb 2010

commonly called MEDTEC, is a challenging field. High quality machining, 100 percent good parts, respect of lead time, best price, trust and long term relationship are just some of the demands. Certifications such as FDA, CE, GMP, ISO 9001 and ISO 13485 are requested and can only be obtained if machining with high quality equipment and skilled personnel.

The MEDTEC Market The medical devices market worldwide achieved more than US$328 billions of sales in 2008 (vs Pharmaceutical US$734 billions).

Europe represented 33 percent of this market with the USA 45 percent, Japan 10 percent and China 2 percent.

There are 20,000 MEDTEC companies Worldwide (about 50 percent within Europe with a total of 435,000 employees).

They manufacture more than 500,000 different devices in 1,700 generic groups spread into 12 specialities. (Cardio, anaesthesia, radiology, orthopaedics, dental, general hospital and more.) With emerging countries such as China and India, one can expect an

enormous growth for the coming 5 to 10 years.

A Bony Issue The orthopaedic market is one of the fast growing members of MEDTEC, worth US$36.7 billion in 2008 (including dental implants) with a market growth of 11 percent per year between 2000 and 2008.

It is traditionally divided into three segments, orthopaedic, spina l a nd denta l. In 20 08, Orthopaedic represented 74 percent of this market, where spinal and dental represented 18 and 8 percent respectively.

Interesting though is the fact that the compounded average annual growth rate was 9.24 percent for orthopaedic, 12.45 percent for spinal and 12.98 percent for dental.

Machining Medical Devices Besides the demands for quality and precision, the main challenges faced by parts manufacturers can be summarised by three characteristics: shape, material and size.

Shape: Bone screws, orthopaedic and dental implants are designed with complex forms of threads to match

industryspotlight

perfectly with the different bone structure and locations. They are shaped to fit in the body as seamlessly as possible. Machining those unusual shapes demand very flexible machinery and adapted tools.

In dentistry, prosthesis are digitised and transferred onto CAM system before machining, nece ssitating sophisticated equipment and software.

Bone screws, orthopaedic and dental implants are designed with complex forms of threads to match perfectly with the different bone structure and locations

Material: The materials used for MEDTEC devices include stainless steel, titanium, cobalt chrome, PEEK and other alloys with carbon fibres.

These varieties of materials require machines and tools manufacturers to constantly look for new processes and tools.

Stainless steels and titanium are the materials most used for medical devices. Stainless steels typically

are used for devices that will not stay in the body permanently.

Titanium typically is preferred for medical implants because of its lightweight, high strength and biocompatibility. Also, titanium implants are compatible with magnetic resonance imaging and computed tomography imaging procedures.

Machining titanium alloys requires cutting forces only

slightly higher than those needed to machine steels. However, titanium alloys have metallurgical characteristics that make them more difficult to machine than steels of equivalent hardness.

Heat generated by cutting titanium does not dissipate quickly because of its poor conductivity.

Therefore, most of the heat is concentrated on the cutting edge and the tool face. The metal

generates oxygen when it burns, so the fire can become self-sustaining.

Machines used to machine titanium must be equipped with fire suppression systems.

A Sneak PEEK PEEK polymer tends to replace titanium for some applications.

It is a strong thermoplastic that retains its mechanical properties even at elevated temperatures. This flame retardant material is abrasion resistant, has high impact strength and a low coefficient of friction.

Medical-grade PEEK possesses those same physical properties in addition to biocompatibility, high chemical resistance and compatibility with several different sterilisation methods.

It is also naturally radio translucent when viewed using X-ray, MRI or computer tomography.

This provides doctors with an unobstructed view of tissue and bone growth around the PEEK implant during the healing process.

A carbon-fibre-reinforced PEEK is also available, which offers high wear resistance for components such as articulating joints.

Shops typically receive PEEK in the form of rods that can range from 6 to 150 mm in diameter.

Before machining, the material must be stress-relieved through an annealing process. This decreases the likelihood that heat generated during the cuts will form surface cracks and internal stresses.

However, medical-grade PEEK reinforced with carbon fibre must be approached differently. For instance, carbon-fibre-reinforced PEEK should be heated just prior to machining in order to soften the material and reduce tool wear. The chips produced from machining most medical-grade PEEK polymers can be collected and recycled for industrial applications.

As with all medical components, precautions must be taken to prevent surface contamination of PEEK work pieces. One precautionary measure 60

metalworking equipment news Jan-Feb 2010

PEEK polymer tends to replace titanium for some applications

is to dedicate the machine, fixtures and tools to machining only that material. Some shops also insist their employees use gloves when handling PEEK to keep oils off the part surface.

New materials are surfacing such as alloys of Titanium mixed with Zirconium. They are 50 percent stronger than pure Titanium.

These materials enhance Osseo integration (a direct structural and functional connection between living bone and the surface of a load-bearing artificial implant, typically made of titanium) process for dental implants, reducing the size of implants in the future.

Another newcomer is the shape memory metal Nitinol. It is finding its way into an increasing number of medical devices. Medical professionals are gaining a better understanding of both human physiology and the properties of this material. It is used for dental burrs and root treatments. More applications are found daily.

As times goes, more materials will appea r on the ma rket, producing more challenges but also more opportunities.

Size: Although bone screws and some implants did not change much in size for some years there is a push for less invasive surgery.

This trend gives birth to a range

of new devices getting smaller as time goes. Minimally invasive surgery with navigation systems allows reducing incision sizes, reducing trauma and hospital stay and providing patients with a shorter rehabilitation time.

Hopping On The Bandwagon Ma ny pa r t s ma nu fac tu rers have already joined this field, contributing to enhancing human health through medical devices.

Many more will join, attracted by the challenges and rewards as the MEDTEC market will continue to grow as expected.

Every new technology added or material change to the existing implants and medical devices needs to go through a long acceptance process being technically and clinically tested before getting FDA/ CE market clearance.

This long process is a chance for the machine tool industry to understand the changes and develop machine adaptations or new machine kinematics.

It allows them to offer the best machining solutions and technical support for the next generations of components. It is therefore extremely important for part manufacturers willing to move into this field to select the highest quality machinery.

Boosting Efficiency

In Medical Device Manufacturing

Using Delcam’s PartMaker CAM software has given a medical device maker the ability to manufacture complex, high-quality medical parts efficiently. By Peter Dickin, marketing manager, Delcam

C

-Axis, a medical device manufacturer uses a range of six multi-axis CNC mills and Swiss-type lathes, the most complex of which is a twelve-axis Star ECAS-20T. When programming such sophisticated parts on such complex machines, being able to quote, program and set jobs up efficiently is paramount.

Jeff Haley, the founder and CEO of C-Axis, recognised the oppor tunity for contract manufacturing of medical devices in Puerto Rico. Since then, the company’s Puerto Rican operation has grown to over 50 employees to serve a number of medical device companies on the island, including Medtronic, Stryker, Johnson & Johnson and US Surgical among others.

“Our biggest challenges include designing a machining process that meets our quality standards, proving out the processes before inter r upt ing t he machine’s production, and reducing our setup times,” says Mr Haley.

Optimising Processes “Our PartMaker CAM software allows us to design and troubleshoot our processes off-line, on an inexpensive computer instead of on a very expensive machine tool.

62

metalworking equipment news Jan-Feb 2010

We can examine and optimise the process prior to even starting the set-up. When we load the programs and set up the machine, we are virtually ready to start production,” Mr Haley explains.

“Without the software, we would not be able to do as much complex milling a s we do,” says Jeff Geronsin, the plant’s CNC programmer. “Even basic programming can be done with PartMaker in half the time that it used to take writing it manually.

For example, if we are milling out pockets and decide to change an end-mill size, the software program can do calculations in seconds which could take hours when programming manually.”

“Medical parts require a level of perfection that is not seen on other types of device,” claimed Mr Geronsin. “The cosmetic look of the part is very important to customers. As a result, we’ve had to do surface machining on our Swiss machines. Without the software program, we’d have had to turn down those components.”

The geometric complexity of the medical parts is compounded by the complexity of the company’s multi-axis Swiss-type lathes. Two of their Swiss machines require three simultaneous CNC programs to be

written to support the machines’ numerous axes.

Maximising Cycle Time The software program lets the user synchronise the machine’s programmable axes to achieve the optimum cycle time.

Once the synchronisation strategy has been set, the software displays a visual time study, showing the amount of time being spent on the main spindle, the amount of cycle time on the subspindle, and the overall cycle time incorporating any overlapping machining time.

The results are shown in the form of a histogram that indicates where additional opportunities for time savings exist. The software also produces cycle times for use in quotations.

Once the process of developing tool paths and performing process synchronisation is complete, the part can be simulated on screen in a 3D simulation. This detects any tool collisions or machine crashes. With pa r ts getting smaller and more complex, this visualisation capability is critical to the continued success at the company.

Meeting

The manufacturing fraternity must match the continuous R&D in medical devices in order to equal the dynamic growth in the medical industry.

By David Zola, chief technical officer, non-rotating and hole making tools and Yair Selek, medical industry project manager, Iscar.

Expectations T he me d ic a l i ndu st r y continues its dynamic growth to be an important and valuable channel for the consumption of cutting tools.

This growth is a result of extensive R&D as well as the increased lifespan of people in the Western and Asian regions of the world.

One sp e cia lt y a re a t hat contributes to the industry’s growth is the orthopedic implant market. As a result, manufacturers are constantly searching for new and improved turning centres and cutting tools to ensure a competitive edge.

Complex Machining Manufacturing medical devices entail machining small, complex p a r t s made f rom d i f f icu ltto-machine materials, such as titanium or stainless steels, at a high level of accuracy.

The machining process of these intricate-shaped orthopedic devices designed to replace bones and joints, is equally complex.

Devices machined from bar stock require a lot of material to be removed, causing the process 64

metalworking equipment news Jan-Feb 2010

to be expensive due to the low machinability rating of many of the materials involved.

As a result, some parts are cast to near net shape, and that often requires complex and expensive fixturing. Another factor that adds to the complexity of machining is the tight tolerances required.

These considerations have led to the development of new machining technologies and solutions aimed at assisting SME shops to manufacture medical parts in the most competitive and productive way. Advanced turning tools, coupled with grades, innovative geometries and chipbreaker designs are capable to manufacture complex shapes while maintaining tight tolerances.

Enter Titanium The main differentiating feature in medical part manufacturing is that 90 percent of the implant components are made of titanium alloy Ti6Al4V, an unfamiliar metal in this industry.

It is the most popular material for medical implants, due to its lightweight, high strength

and biocompatibility. Titanium implants are compatible with magnetic resonance imaging and computed tomography imaging procedures, and do not cause any interference with those procedures, should they be required after the implant is made.

It is commonly used for hip joints, bone screws, knee joints, bone plates, dental implants, and surgical devices, though recently cobalt and chromium alloys have been gaining popularity.

Coming Into Terms With Titanium Machining titanium alloys require cutting forces comparably higher than those required for machining steels. In contrast, titanium alloys present metallurgical c h a r a c te r i s t i c s t h a t m a ke machining more difficult than steels of equivalent hardness.

Think of it as stainless steel but with a tougher, stringier chip, plus a strong tendency for breakout at tool entry and exit points.

Also, titanium is known for having the characteristic to generate work-hardening. That condition leads to a high shear angle during machining which causes a thin chip to contact a relatively small area on the cutting-tool face.

With its relatively low modulus of elasticity, titanium has more

industryspotlight

www.equipment-news.com

‘springiness’ than steel, so work tends to move away from cutting tools unless heav y cuts are maintained or proper backup is employed.

In addition, the high bearing forces produced by machining, combined w ith the friction developed by the chip as it travels, result in a great increase of heat on a localised portion of the cutting tool.

Heat generated by cutting titanium does not dissipate quickly, due to poor conductivity. Therefore, a substantial amount of heat gets locked between the cutting edge and the tool face. This combination of high bearing forces and heat, produce crater wear adjacent to the cutting edge, resulting in rapid tool breakdown.

Lastly, titanium alloys have a strong tendency to alloy with or to react chemically with materials in cutting tools at tool-operating temperatures, and they have a tendency to gall as chips weld to the cutting edges of tools.

Solutions & Future Iscar has conducted an analysis of the orthopedic implant market to determine the most effective types of tools to improve the manufacture of these very critical devices. As a result, specific lines of tools, inserts and chipbreakers for machining Ti6Al4V were designed in order to achieve the precise tolerances required by the industry.

Milling: The company has developed solid carbide endmills with sharp cutting edges for bowl-shaped parts as well as deburring. These endmills can provide a 0.01 maximum honing for semi-finishing and finish operations. Tools for machining both titanium and stainless steel, using a submicron base with a PVD coating were also developed.

This allows the machines to run at high speeds and feeds.

Advanced turning tools produce the capability to manufacture complex shapes while maintaining tight tolerances

Drilling: Solid carbide drills for diameters as small as 0.8 mm with sharp cutting edges and a P geometry are available.

Re a m i n g : S ol id c a rbide reamers, from 1 mm diameter, are produced with sharp cutting edges and utilise an S geometry.

Turning: Our research shows that for turning applications, the industr y ha s a definite need for improvements, both in insert grades and chipbreakers.

These inserts are provided with polished chipbreakers and a wiper, thereby providing the user with good surface quality in both semi-finishing and finishing applications.

Miniature parts manufacturers supplying the medical industry no doubt have challenges that lie ahead, but when equipped with proper tools, they can actually make the jump over their competitors and move ahead.

Iscar: Inserts For Boring, Profiling & Threading Picco 050 is a family of inserts with a ground chipformer for profiling and turning. Designed

by Iscar, it is used for materials that have a tendency to produce chunks of uncontrolled chips that entangle around the insert and the workpiece.

The inserts enable short controlled chips, resulting in continuous non-stop machining.

Tool life is extended when the chipformer reduces the cutting force, resulting in lower plastic deformation on the cutting edge.

Equipped with a CBN tipped cutting edge for profiling and turning of hardened steel, the inserts enable machining at higher cutting speeds, and provide longer tool life when compared with standard carbide Picco inserts. They are available with 4.0 to 7.0 mm shanks for minimum bore diameter of 4.0 mm. MEN Enquiry No. 1404

T

he ma nu fac tu r ing of medical instruments and implants is characterised by nano-structures as well as the demand for highest precision in terms of surface quality, absence of burr, and materials residues.

While established fabrication technologies increasingly face their limits, laser micromachining provides optimum preconditions for the required quality and precision since machining is accomplished in a contactless fashion and the extent of the heat-affected zone is very small. Important applications stem from the ranges of ablation, surface processing, cutting and micro drilling.

Laser Micro-Ablation Excimer laser ablation is used in conjunction with mask projection techniques to produce complex microstructures. Special multiplemask techniques have been developed which, together with synchronised workpiece motion and laser firing, are used for the manufacture of features such as micro-channels, ramps and contoured surfaces with channels.

These techniques allow planar microstructures to be combined and superimposed onto curved or multifaceted shapes, thereby

66

enabling hitherto unobtainable structures to be produced.

Lasers are capable of precisely and even selectively ablate materials from metals, ceramics, polymers or multilayer stacks. Machining in this range is preferably done with short-pulsed or ultrashort pulsed lasers. The latter tools allow for the generation of smallest possible microstructures (<15 µm), the fabrication of 3D objects, and layerby-layer ablation of coatings.

These technologies are utilised for the removal of plastic coating from surgical instruments or for the manufacturing of catheters.

Using this technology, superficial structures in the micron range can also be realised, for example for the optimisation of the ingrowing behaviour of implants or in microfluidics.

Cutting With A Beam Laser micro cutting is a technology used in the ma nufacture of such medical devices like flexible intravascular tubes, endoscopic tools, guide wire holes, biopsy instruments and micro connectors.

For laser micro cutting of surgica l instruments a nd implants, foils and wires can be cut on 10 µm scale. Moreover, foils and tubes can be machined with cutting widths well below 20 µm, microstructures and 3D objects possessing a resolution of just a few microns can be generated.

The Finer Aspect Of Drilling Due to their focusability, lasers are suited for the drilling of very fine holes. For the drilling of plastics, excimer lasers are utilised while the machining of metals and semiconductors is accomplished with DPSS (diode-pumped solid state) laser sources or picosecond lasers. Blind holes as well as clearance holes can be obtained.

A particularly large development potential is attached to the usage of helical drilling heads for generating of micro holes (diameter >50 µm) with precisely controllable taper in up to 2 mm thick metal sheets. With the advent of the laser technology, entirely new perspectives for design and functionalisation of cannulas, nozzles, implants, and micro filters are opened. MEN Enquiry No. 1405

Rewarding Overcome Titanium Machining:

Those Who

The difficulties of titanium machining are well documented but machinists are just a few steps away from unleashing the full potential of the material. By Joson Ng

metalworking equipment news Jan-Feb 2010

Problems Due To Mechanical Properties The main challenges in machining are posed by the mechanical and material properties of the metal.

They are classified under heat conductivity, modulus of elasticity, fatigue and work hardening characteristics.

A s a meta l of poor heat conductivity, heat generated by the cutting action does not dissipate quickly. Therefore, most of the heat

?

Difficulties In Machining Dubbed the ‘miracle metal’ or ‘space-age metal’, pure titanium has tensile strength of about 63,000 psi and certain titanium alloys achieve tensile strengths of over 200,000 psi.

These numbers make it roughly as strong as steel but weighing about half of steel, titanium certainly lives up to the billing of ‘miracle metal’.

Of course, there is no such thing as a perfect material, the down side of titanium is the difficulties in machining. Supra Alloys, a titanium supplier to the aerospace and medical industries headquartered in Camarillo, USA, documents the difficulties from the physical, chemical and mechanical point of view.

According to the supplier, cutting occurs at high temperature where chemical reactivity is arguably at its peak. Coupling that with the strong alloying tendency of titanium, problems like galling, welding and smearing present machinists with a real challenge.

is concentrated on the cutting edge and the tool face.

In addition to the problems posed by heat, the low modulus of elasticity the material possesses, gives it more ‘springiness’ than steel. Holding workpiece becomes a problem. Moreover, slender parts tend to be damaged under pressure. Other problems include loss of accuracy and tool rubbing.

Another noteworthy point to consider in the machining of titanium is its work-hardening characteristics. They are as such that the metal demonstrate a complete absence of ‘built-up edge’ during machining. The lack of material ahead of the cutting tool causes a high shearing angle to form. This causes a thin chip to

achining titanium is by no means an easy process but with the attractive strength to weight ratio ever so enticing to engineers and designers alike, many are prepared to bite the bullet and machine the material the best way they know how.

Does it have to be a painstaking process? Some machine shops may choose to avoid the material altogether but with the metal taking the aerospace and medical industries by storm, not many shops have the financial clout to turn away from titanium.

With some alteration to existing machines, tools and mindset, machining titanium need not be fronted with difficulties.

Machine Titanium Well According to RTI International Metals, producers of titanium, good tool life and successful machining of titanium alloys can be assured if some guidelines are observed. The poor heat conductivity of titanium can be countered on two fronts.

One way is to reduce heat buildup and the other is to remove heat altogether. Heat can be removed by introducing high quantity of cutting fluids. Sharp tools should be used to reduce heat buildup and galling.

Other tips to achieve good machining performance are the utilisation of lower cutting speed, maintaining high feed rates and regularly removing turning from machines.

Milling & Grinding In milling of titanium, the cutter mills only part of each revolution.

There is a chance that the chips will adhere to the teeth during that portion of the revolution that each tooth does not cut. Subsequently, the tooth may be da maged when the chip is removed on the next contact.

Chipping is usually the chief cause when the cutting edge fails. As a result, though with the increased cutting speed of 20 to 30 percent, it is not enough to compensate for the additional tool grinding costs making carbide tools less satisfactory compared to high speed steel.

Consequently, it is advisable to try both high speed steel and carbide tools to determine the better of the two for each milling

job. The use of a water-base coolant is recommended.

When it comes to grinding, three factors determine the success or failure of the process. A combination of abrasive wheel, wheel speed and grinding fluid often set machinists on the right track.

In terms of speed, it should be in the lower range compared to the speed used in the conventional

grinding of steels. With grinding fluids, water-sodium nitrite coolant mixture should be paired with aluminium oxide wheels. A silicon carbide wheel operates best with sulfo-chlorinated oils but it is important to flood the work when using these oil-base coolants as they can present a fire hazard. MEN

The high bearing force, in addition to the friction developed by the chip as it rushes over the bearing area, results in localised heating of the cutting tool. Coupling that with cratering action near to the cutting edge, results in rapid tool breakdown.

Peter Dickin Marketing Manager Delcam

The main lesson would be to avoid complacency. It is very easy for companies to take business for granted when times are good. In fact, it is during those times that investment in new technology is most important so that firms are more competitive when the market hits any downturn.

Louis Mussa President Asia Pacific Hexagon Metrology

Those of us who have been through the previous crises know they all come to an end sooner or later. You need to hold the line, remain positive and stay close to your customers and partners, who sometimes face problems bigger than our own.

Jacob Harpaz CEO Iscar, President IMC Group

Continue to invest in R&D during the crisis, customers look for innovative solutions to allow them to get through the slow down and stay competitive.

Chip Dreier Marketing Director, Asia Pacific Kennametal

Kennametal did a good job anticipating the economic downturn in 2009. We used this as an opportunity to make our business more market and customer focussed. Moving forward, we will be one enterprise working together for the benefit of our customers and aligned to their needs.

Dr Hans-Peter Laubscher MD Trumpf

We implemented the right measures very quickly. In 2008, we began a group-wide performance improvement program in all divisions and departments. The measures implemented from this program kicked in during the second half of the fiscal year and led to savings of US$82 million.

Lastly, through flexible production, we have been able to prevent the stockpiling of warehouse inventory. We are adapting our production plan to orders.

Navigating the economic storm of 2009 requires dexterity, leadership and also certain amount of courage. The captains of the industry in this special feature have come through the test with great aplomb.

In the next few pages, leaders in the metalworking industry reveal their thoughts, the valuable lessons learned and share with us the plans they have in store as they embark on hopefully a brighter 2010.

In your opinion, has the market turned around? What can we expect in 2010?

It seems safe to say that things have stopped getting worse but there are mixed messages about when the general economic situation will start to recover. Even when recovery does start, it will be some while before the overall level of activity gets back to where it was. The rate of recovery will vary by country and by industry sector.

There are grounds for cautious optimism. Certain projects in certain sectors have restarted, enquiries are increasing, attitudes toward investments seem to be improving, so even nobody knows exactly when the crisis will be over there is now a sun shining at the end of the tunnel.

In certain segments and geography the market has rebounded to pre-2008 level, in others it still lags. We expect to see continued recovery into 2010 and are acting accordingly by maintaining and strengthening our presence within the different markets and investing in new capacity and technology.

As we enter a new year, we are beginning to see increased optimism and a general recovery led by economies of China and India. This is great news.

In 2010, we expect the emerging markets to take a leading role in the global recovery and be a key focal point for most businesses.

Leading economic indicators are signalling that we have bottomed out and that markets are recovering. However, it would be premature to begin talking about an upswing. First of all, this recovery is starting at a very low level; secondly, it is only very faintly reflected in the order books. But we are noticing that the mood is brightening slightly in the individual markets.

We share the expectations of the major industry associations that the situation will improve starting in 2010. What is open, however, is how fast the recovery will set in and how strong it will be.

Clean energy and the growth in automotive and aircraft sectors are especially interesting. We, as a supplier to these industries, are in a great position to work with our customers to help them meet their goals of higher technology and improved quality.

Dr Hans-Peter Laubscher MD Trumpf

Flexible, efficient processes and innovative products. Innovations make new applications possible, increase independence and expand capacity. Growth potential improves the competitive advantage and a higher workload cuts part costs significantly.

We have to look at the broad picture of products over the whole service life of the machine. Customers receive the latest technology with income potential and favourable operating costs from us.

Energy efficiency per part must also be taken into account in the cost analysis.

What are your marketing/general strategies for your company in 2010?

As mentioned before, Delcam will be focussing more on the healthcare industries in 2010. There will also be more emphasis on internet marketing, for example through our Delcam online TV channel.

To continue to support our customers and partners with products and services. Lead them into the future with a range of solutions to help them improve the quality of their products and processes. We will continue to develop and improve our presence in Asia through capillary distribution with particular attention to the professional development of our human resources.

Our goal is to increase our customer’s profitability by introducing advance tool concepts and in turn being recognised by our customers that we are providing a value that is beyond the application support and tools we provide. It is the performance, productivity and profitability we ensure through our innovations.

In 2010, we will employ the same strategy, continuing on geographically balancing the company sales among equal thirds in North America, Western Europe and rest of the world. We will also grow our AMSG business to represent 50 percent of our sales. We will focus on fulfilling our long-range vision of the company’s future.

We are approaching the markets with a simple slogan ‘Innovations that pay off’. Healthy, well-placed companies can turn the crisis to their advantage by optimising processes and work on projects that, in the past, were set aside because of the high pressure to produce and deliver.

Increased capacity resulting from increased productivity can mean that one new machine can take the place of two or three older ones. This leads to improved company efficiency, rules out additional undesirable guarantee and service costs, permits more flexible work models and may provide a savings in personnel costs.

Special Report:

Metalex Thailand 2009

The metalworking industry is looking forward to 2010, where previous lessons learned and experiences gained can be put to good use. By Joson Ng

Reed Tradex:

Creating A Much Needed Buzz

I

n ma ny ways, a trade exhibition is a good indicator to test market sentiments. For the metalworking fraternity in South-east Asia, Metalex Thailand offers an opportunity for those who may still be ‘sitting on the fence’. The organisers of the event recently came to Singapore to promote the show and Asia Pacific Metalworking Equipment News caught up with Nichapa Yoswee, MD, Reed Tradex to talk about the economic situation in Thailand, the possible economic recovery and also Metalex Thailand 2009.

“I think signs of a recovery are already here,” Ms Yoswee says confidently. By no means a conjecture, she went on at length to back up her claims. “I have quite a few discussions with my friends who are factory owners and also people 74

metalworking equipment news Jan-Feb 2010

who are tool suppliers. To quote you an example, a tool supplier received two orders recently (last quarter of 2009) and those orders generated revenue that covered the whole year (tooling),” she says.

In her line of work as event organiser, Ms Yoswee has to be in touch with the industry in order to stay relevant and even take a leading role in identifying new market trends.

Based on her expert observation, the stimulus packages initiated by various governments have taken effect and tangible results can be seen especially in Thailand. Says Ms Yoswee: “In terms of production, majority of the factories I visited or researched upon are operating up to 70 percent of their capacity. A big improvement from last year , that is why I believe the rebound is here.”

Automotive Industry In Thailand According to Ms Yoswee, the resurgence does not limit itself to the metalworking industry. The automotive industry of Thailand, arguably one of the cornerstones of Thailand’s economy, remains stable and competitive, even as China emerges as one of the largest automotive producers in the world.

Analysing the situation calmly, she says: “I think China has their own competitive edge and so do we. I think the difference between China and Thailand is that they have a domestic market to serve as well as the export market. For Thailand, auto parts are basically exported to our partner countries in Europe and also Japan.”

Believing the land of smiles is a firm and secure supplier for automotive companies based in Europe and Japan after proving their quality against stringent ISO requirements, she feels China will have to go through the same process before they can be direct competitors.

Another bright spark for the automotive industry in the kingdom is the rise of eco cars. “Now that the eco car is confirmed, there are going to be a lot of new plants opening up. That would require new set of skill and machineries.

As the plants and parts have to be remodelled, that offers a huge opportunity for Thailand and also event organisers,” she predicts.

Eye On Metalex Thailand

This year, the buyer s at the show are largely c l a s s i f i e d u n d e r t wo groups – according to Ms Yoswee. “I think the first group consists of those who have to sustain the local and export order.

Since their capacity is still running at roughly 70 percent, they need new technology but not a

huge investment. Those involved in the eco car project however, need new technology because the project is something new and so heavy investment is inevitable,” she notes.

“The second group would be those who want newer technologies to upgrade their production.

The buzz at the exhibition floor can be attributed to the diverse sales pattern.”

Features & Future In Asia alone, there are many shows that a re dedicated to machine tools and technologies. In order to survive or carve a good reputation for oneself, it is imperative to

have a unique feature. “ Fo r M e t a l ex, o n e difference between us and other machine tools shows particularly in East Asia is we are consumers of technology or importers. Those shows emphasise technology as the manufacturers are based in the host country itself,” she offers.

In conclusion, she says: “In a real sense of the word, trade is very much the focus in Metalex, it is where all the buyers are, making it a powerful trade forum in South-east Asia.”

Hexagon Metrology:

Extra Effort

D

espite posting good financial figures in uncertain times, no one is taking anything for granted, a testament to the work ethics instilled from top down.

Vastly experienced in the field of metrology, Taveesak Srisuntisuk, MD of Hexagon Metrology Thailand has some 28 years worth of knowledge.

Every ounce of this knowledge was called into action earlier in 2009 as the economy took a plunge for the worse. Fast-forward a few months on, Mr Taveesak is exhibiting at Metalex Thailand and sharing with Asia Pacific Metalworking Equipment News the lessons learned as he looks back on 2009.

Believing that the worst is over, he says: “From our visits to existing and potential customers, we can tell they are more optimistic now.”

In addition, he notes: “There have been many enquiries recently

and people are beginning to explore the possibility of equipment purchase. They are waiting for the right time to buy.”

According to Mr Taveesak, there are more indications that the arrows are pointing up. “Hexagon Thailand concentrates a lot on the local automotive industry. More often than not, the number of cars sold in the last two months is a telling indicator. Moreover, there are projects pending. In Thailand in 2009, they initially forecasted to produce a total of 700,000 units of cars. Now the forecast has been revised upwards by 10 percent.

As such 2010 cannot be worse,” he says.

Lessons Learned Though 2009 was a difficult year for most, Mr Taveesak reveals the Thai branch under his charge made a profit. Owing partly to Jan-Feb 2010 metalworking equipment news

Metalex Thailand 2009 the backlogs from 2008, the good performance can also be attributed by the adjustments made by the company as a whole.

“In some countries, we had to reduce headcount although we kept all the engineers and administrative staff. We as the head of branch also volunteered to reduce our salary for one quarter, in a show of unity,” he says.

Taking To The Skies Hexagon Metrology as a whole has many interests across the world and as Mr Taveesak discloses is strong in the aerospace and medical industries in Europe especially. With Singapore emerging as a regional aerospace hub, he feels this is the chance for the Asian branches to get more involved in this industry.

However, he also reminded us that there are big challenges in the aerospace industry.

“They have small parts with ver y stringent dema nds on accuracy and they also have very big parts that are no less easier to manufacture or measure. The difference for big parts is you cannot use regular CMM so laser tracker is used instead,” he adds.

Services Rendered Mr Taveesak has represented Hexagon in Thailand for some 15 years. During his tenure, he instilled a service-oriented attitude to his employees towards users.

Quoting an example, he says: “In customer service, our reaction time is a day in any part of Thailand. If someone were to call us today, we will send our engineer down latest by the next day.”

To add on, engineers have their own account to take care of in order to forge a closer relationship with the customers.

Hurco:

Staying Grounded

T

a k i n g t he p r a c t ic a l approach and staying result oriented is the route to take into 2010.

Hurco was one of the exhibitors i n t he re ce nt l y conc lude d Metalex Thailand and Asia Pacific Metalworking Equipment News caught up with Andrew Foo, regional sales manager, Hurco SEA for his thoughts on the show, the economy and the up coming trends.

“As far as turnout goes, I would say it is a case of ‘so far so good’.

It is roughly the same as last year.

Sales leads are definitely there but unfortunately, we have yet to locate a quality customer,” he says.

Though he has yet to see any genuine results, he conceded that the show is attractive to his company as Thailand is a market they cannot go without.

“We are exhibiting here today because Metalex is the biggest 76

metalworking equipment news Jan-Feb 2010

machine tool show in the whole of South-east Asia and everyone involved in this field in this region has heard about it,” he notes.

Reality Check When queried, Mr Foo prefers to take a more philosophical approach when he expresses his views on the economic outlook in 2010.

“Are we on a recovery run? Yes and no but one thing is for sure, the war is not over. Yes and no because the market is up in some months as we received good enquiries. Other months can be quiet. There is a upward trend but I am not sure if it is a recovery,” he says.

“Realistically speaking, I feel the first half of 2010 should be the same, it may pick up from third quarter onwards,” he adds.

Lessons & Trends In a difficult year where some

Measuring Up Metalex Involved with Metalex Thailand as an exhibitor since the first instalment, Mr Taveesak has seen the event grow larger and more influential over the years.

“For 2009, the number of visitors is very good. The number of enquiries look good as well. It is above my expectation,” he says.

The improvements though encouraging can only materialise into real results through hard work that is absolutely critical for 2010 as he concludes: “Even in a crisis, there are always newcomers, that is something we can focus on and something we need to guard against.

With new competitors emerging from the horizon and established names finding their feet again, it will be tough to keep sales. We need to work even harder in 2010.”

Wenzel Asia Pacific:

Maintain Focus

W

ith the spot-light firmly on what is t r uly impor ta nt, Wenzel Asia Pacific is well on its way to brea k new grounds.

The year 2009 has been a real acid test for many and even for a seasoned veteran like Tan Boon Sun, MD, there were lessons learned as well.

“As we are quite specialised in our industry, we have to stay focussed and maintain a strong foundation. The reason being our industry does not function like a consumer product market where some merchandise can be bypassed at an alarming rate,” says Mr Tan. Looking at his field of metrology, he shares with Asia Pacific Metalworking Equipment News that it has not changed too much. He explains: “If you look at the CMM, although it has been around for some 50 years, the basic shape of the machine remains similar whether you like it or not. In terms of drive system, it is still running with air bearings and the accuracy 78

metalworking equipment news Jan-Feb 2010

still remains or there are only little improvements (still not able to break a micron). About 90 percent will remain and what you can change is probably only the cover, shape and size.”

Eye On The Economy With the financial outlook for 2010 looking more positive on a whole, we got Mr Tan to comment on his field, ie: metrology.

“Although all the indicators seem to be displaying an upward trend, they are unfortunately not reflective of our industry,” he says.

Going deeper into the issue, he offers: “In our sector, people are still adopting a ‘wait and see’ attitude. Potential customers are more meticulous these days when picking out a machine. They also exercise more caution over every penny they spend.”

In geographical terms, he feels that the worst is over for North Asia.

He says the aerospace industry, wind industry and the automotive industry, the three big sectors the company looks at are still posting

good results in China.

Metalworking Industry When it comes to metalworking machineries, the buying pattern has every chance of improving as far as he is concerned. Predicting a better year for his machine tools counterparts at Metalex Thailand 2009, he says: “It is almost inevitable that the machinery segment will experience an upward buying trend in 2010 as people have been putting off buying machines.

However, should there be another downturn for them, it will be twice the impact we had before but I think it is not likely.”

Turning the attention back to metrology, it is important to spot potential in new areas as the arena according to Mr Tan is saturated.

Adopting a practical view, Mr Tan admits that though a breakthrough is difficult to achieve, but by applying new technologies and a new approach to measurement, that may not be a distant dream.

JETRO:

Tread With Caution

S

tay i n g v ig ila nt a nd alert in order to react to changing economic climate is a prudent way to approach a supposed recovery.

Occupying a sizeable floor area at Metalex Thailand 2009 with 12 participating Japanese SMEs is the Japan External Trade Organization (JETRO) pavilion.

After witnessing a tumultuous few months in 2009, the early sign of recovery is beginning to show, as far as people in the positive camp are concerned.

As for Shigenori Hata, VP, JETRO Bangkok, he approaches positivity with caution.

“Yes I believe the worst is over when I speak to the executives of machinery industry. The recovery however will be a gradual affair,” he says.

Though things appear to be on the up for now, he also sou nded a possible hiccup along the way. “The recovery is also dependent on the various economic stimulus packages put together by countries all over the

world namely economic super powers like the US, China and Japan. If the packages wear off, the economic recovery may also lose momentum,” he adds.

Lending A Helping Hand Helping Japanese SMEs find their way in the global market place is one of the primary missions of JETRO according to Mr Hata and this intent can clearly be seen at the show.

“We utilised our supplementary budget this year to organise this pavilion for our SMEs. As such, they pay a very special rate for their booth,” he explains.

Assistance does not stop there.

The organisation has nine offices in Bangkok and they are made available for any interested Japanese company for a nominal rental fee for up to three months. MEN Enquiry No. 1607

Radio Telepathy Steel Recycling:

To ensure the continuity and quality of steel production, automation technology and industrial wireless LAN are used to ensure fast and safe data transmission. By Luca Piller, I IA&DT AS, Siemens Zurich.

S

wiss Steel in Switzerland turns 600,000 tonnes of scrap iron per year into high-quality steel. In the continuous casting plant, the molten metal is cast into 10.8 m long billets. They are the basic material from which the rolling steel, in rod or wire form, is produced in the rolling mill.

To ensure product quality in the steel plant, data such as metal composition, weight, and the location of the conveying devices are sent wirelessly via radio to the control system, which further distributes them.

The data are recorded at the location where they are created and are transmitted via network components access points. Despite the harsh industrial environment, the radio signals that reach the control system receiver are of required quality that there is no need for further protection of the radio data.

Melting Pot At the beginning of the melting process, the tonnes of scrap are initially heated up to 1,650 deg C in melting furnaces with light arcs from electrodes. The experts at the steel plant know the ingredients of

With modern automation, the raw metal is melted, cast into billets in the continuous casting plant, and then processed as high-quality steel

The network components have to operate in harsh environments

most of the scrap deliveries. When loading the basket for the melting furnace, weights and recipes are passed on to the production control system by radio.

A ra il - b ou nd scrap ca r t transports the basket with its heavy load into the melting furnace hall.

There it is lifted by the hall crane and emptied into the furnace. The transport and loading of the three scrap carts are also monitored via radio connections to precisely determine the consumption levels and storage locations of more than 10 types of scrap.

During the melting process, the furnace supervisor takes regular metal samples and sends them to the laboratory for an analysis.

Melt composition, quality of the raw material and the process duration are analysed. When the melted metal has reached the right composition and temperature, the

slag is drawn off and the red-hot melted metal is poured into the foundry ladle, which weighs more than 40 tonnes. In the subsequent ladle furnace treatment and, in some cases, vacuum treatment, the melted steel is heated further, alloyed with additives, and purged with inert gas before the ladle is hung on a rotating tower with a crane.

Wireless Control As soon as a process ladle is empty, a new ladle can be swung in and continuously emptied into a distributor through a floor drain.

This distributor then distributes the liquid steel into the four channels (chills) by means of a control system. The chill must oscillate constantly during casting to prevent the steel from sticking.

Steel billets run over a discharge line that is fitted with conveyor

rollers. The rollers are equipped with converters and gear motors, which ensure smooth motion – from the rotation of the foundry ladle to the emptying into the chills. All the electronic controllers and components used feature reliability even under difficult conditions, because a failure could have serious consequences for productivity and safety.

In order to implement this solution, Swiss Steel first had to extend the radio network of the scrap carts because the old network had radio black spots. The company chose a network with Scalance WIWLAN components.

Setting up this radio network made great demands on system technology.

Dragan Todorovski, production systems manager at Swiss Steel, sums up the situation: “The enormous machines and the harsh conditions in steel production are not ideal for setting up a reliable radio network.” He therefore made drawings of the halls and marked the transmitter stations first with the support of a specialist.

The drawings were then read into the test program for radio networks, to identify any gaps and to improve the network.

“We measured the signal strengths after setting up the radio system and only had to make minor readjustments,” Mr Todorovski reports. “This considerably reduced the commissioning time and operation was started without any trouble,” he concludes.

Metal composition, weight, location of transport units, and other data are transmitted via wireless communication to the control centre. The control centre then in turn distributes the information to other units. The combination of data collection close to the process and good radio field design ensures reliable wireless communication. MEN Enquiry No. 1608 Jan-Feb 2010 metalworking equipment news

RD &

Makino Asia held a signing ceremony on October 21, 2009 to mark the commencement of a R&D venture.

With some S$75 million (US$ 53 million) invested in the International Research and Development (IRD) Centre, the company signals its intent in multi-disciplinary research, development and synergistic collaborations.

A

ptly described by Dr Moh Chong Tau, president and CEO of Makino Asia as ‘a key milestone in the advancement of the company globally’, the IRD will spearhead the company’s drive in machine tool research especially in the fields of medical, engineering, alternate energy and exotic materials cutting.

The investment amount, over the period of five years, includes the initial tranche of approximately S$20 million, where the majority of which would be building costs.

Over the next four years, additional investments of between S$12 to 15 million each, would mainly be in staffing and related research expenses. The facility would occupy an area of about 3,800 sq m, housing workstations, modelling and analytical systems and simulators.

Regional Hub Singapore became the only R&D centre outside the company’s headquarters in Japan. The decision to pick the city state

was a natural one as Dr Moh explains in his speech to a crowd consisting of delegates from the Singapore Economic Development Board, SPRING Singapore, A*Star, company employees and other distinguished guests.

Says Dr Moh: “Singapore offers compelling value proportion which are numerous and significant.

The country is well-renowned for its political stability and strong governance which is especially important when it comes to multimillion dollar investments.”

Continuing, he adds: “The world-class logistics infrastructure, connectivity and supply-chain management allow for efficient access to not just regional but also global markets.”

Signing Ceremony The crowd witnessed the signing of MOUs and contracts that will see closer cooperation between Makino Asia and government agencies.

For instance, the MOU signed with Singapore Institute of Manufacturing Technology (SIMTech) will see R&D collaboration resulting in the participation of basic and experimental research to develop machine tool and improve reliability.

In addition, the MOU also promotes the R& D of locally manufactured EDM and CNC milling machine, which are used in making high precision components for the aerospace, automotive and medical sectors. MEN Enquiry No. 1701

Ceratizit: Tool Holder Enhances Durability Of Inserts

FluxData: Compact 3-CCD Polarisation Camera

Ceratizit ha s developed a tool holder with a clamping claw made of solid carbide for the machining of brake discs. A commonly known phenomenon when machining brake discs using ceramic and CBN is that the claw which holds the insert in its seat wears out early through erosion.

The C-Clamp, thanks to its compact construction (short distance between screw and clamping point) is characterised by a higher stability than conventional claws, which enables an increase of between 10 and 50 percent in the durability of the inserts.

The FD-1665P by FluxData is a camera system capable of collecting video at three linear polarisation orientations simultaneously.

The optical system can identify stress and defects in aircraft assemblies; â&#x20AC;&#x2DC;seeâ&#x20AC;&#x2122; into the water column in littoral and marine applications; separate specular from diffuse reflectance for material analysis and identification; and automatically detect manmade objects in natural surroundings.

The standard offering for the FD-1665P is 0, 45, and 90 deg linear polarisation filters in front of the three RGB sensors at up to 120 frames per second.
