Pole, Points & Podium

esign and technology are at the helm and heart of it…and the whole value chain of researchers, technicians, both on field and off it, right to the component suppliers, are the reckoning force behind it. F1 is here to stay in India, and the adrenaline rush is intoxicating!

As India got into the Formula 1 frenzy, the odds were against us. The doubt bubbles were getting thicker and bolder. Right from the Indian capabilities to build the fast tracks to handling the whole extravaganza that comes as part and parcel of this upmarket sport, everything was being doubted. The CWG mishandling, acting as a background canvas, wasn’t helping either. And so, the racing day began, with the veteran west almost sure of the Asian dramatics, the betting fraternity was having a field day! But the great Indian risk-taking appetite had a secret ingredient in it this time, which saw an almost flawless racing experience, with the global experts rating the tracks as one of the best. We did get our twists, turns and slopes right. The Naysayers suddenly turned Ayesayers! India achieved the Pole Position. It was all about Points that day. While the racing teams were flying and burning tyres at the same time, in their quest to earn points, India had some other point to prove! And we did prove many points that day. India is now a hot destination for F1 racing, with capabilities to handle this hi-end sport. As it becomes a regular destination in the racing circuits, the logistics will pose and prompt many questions about the viability of cost and convenience of getting these cars here. The answers and solutions to these realities will open a whole new world of opportunities for the automotive and machine tools sector.

With the Champagne flowing and the world cheering this feat, we, at Modern Machine Tools, got down to chart out means and methods of reflecting this newfound ‘formula for success’ into our own machine tools industry. As the world warms up to the idea and as India gets ready to manufacture indigenously made fast cars, this special edition is dedicated to the F1 opportunity and what it can do to the machine tools industry. With high-precision machining tools being used in the fabrication of cars and high quality hand tools specially built to maintain the finished cars, it’s no blank spot that machine tools provide speed and endurance to fast cars. The must-reads include the content spread, which is all about exploring how F1 racing flags big business opportunities for the indigenous fast cars market in India, enabled by cutting-edge machine tools. If that is the dream, an insightful piece written on how the Indian shop floor will undergo a transition once we make our very own F1 car, is what aspirations are made of! Not to mention the cutting-edge measurement devices as F1 cars are all about accuracy and precision & the new materials used and the latest technologies used for the machining process of these mean machines! So it’s Vroom time folks, let’s fasten our seat belts as we zip past our competitors, armed & aided with the right information and expert views in these opportune times and tracks!

Technology & Innovation Your gateway to the latest trends and technologies worldwide

Tool clamping technology

characteristics of the conrods and their competitive power compared to new light weight construction materials (aluminium materials, carbon fibre reinforced plastics) are being improved.

Die forging

Modern technologies ask with increasing importance for a dependable tool technology in the manufacturing process. The aim is to minimise additional processing time. Particularly, in the forging industry with mass-intensive tool, the tool change time represents a considerable factor in the availability of a process chain. For these applications within the range of forging presses quick change hydraulic tool systems and fast clamping systems are developed and used. These systems are individually adapted to the respective operational conditions and requirements (eg single dies for groups of tools in cartridges or on removable, plates tool change car, table adjustment in the forming machine etc).

Semi-hot forming

This compression forming method can be used for the production of highly stressed components with or without flash. It is a highly productive manufacturing method predominantly used for large quantity production. The investigations on die forging are usually regarded in connection with considerations of the appropriate forming aggregates, the tool system engineering and the materials that are to be formed. Especially in the field of technology development adjacent procedures, eg cross rolling for performing, are included into the investigation of the complete process chain. The component and tool development for industrial applications involves the individual operational conditions and requirements of customers production.

Lightweight conrod Semi-hot forming at temperatures up to 9000 C allows an improved near-netshape forming of higher strength steels and component geometries, which cannot be cold form. The design of warm forming processes is based on the experiences in tool engineering of cold extrusion and processing in warm forming. As an example, the main objectives of this development of semi-hot forging of steel conrods with open middle section are residue-minimised component manufacturing and a weight reduction of the component with constant components specific parameters. Thus, the performance 38

MODERN MACHINE TOOLS - December 2011

The development of lightweight components in vehicle design attains increasing relevance due to energy efficiency and future economic aspects. Consequently, major engine components such as crank-shafts and conrods

constantly gain in attention. The current development focuses on the investigation of conrod variants and their static and dynamic component characteristics. Multiple FEM-simulations showed that the basic model of the examined conrod has a substantial potential for the weight reduction. Through several development stages multiple conrod designs were developed and examined regarding their theoretical component characteristics by FEM-computations of deformation and strength behavior. As a result mass savings up to 50 per cent can be realised. The objective of a â&#x20AC;&#x2DC;fatigue endurable component at maximum light-weight designâ&#x20AC;&#x2122; with constant production costs was realised without constraint. The dynamic strength analyses of the durability of the conrod proved that the conrod has a sufficient load capacity with respect to the requirements of the engine.

Precision forging

The technology of precision forging as a warm forming process allows the production of high-strength components. Workpieces manufactured by precision forging have sections in a finished state with very high surface quality and close tolerances. A functional design of the component suitable for precision forging reduces cost-intensive subsequent technologies (e. g. machining and / or joining operations) and shortens overall process chains. The emphasis in the component range of precision-forged workpieces is mainly placed on components of the power train of motor vehicles. At Fraunhofer IWU, a precision forging tool with unique hydraulic volume compensation has been developed, built and tested on a selected demonstrator (double-piece connecting rod).

Technology & Innovation Spin extrusion

Using billets with full cross sections, long cup-shaped parts with circle cylindrical internal forms, internal profiles and polygons can be manufactured in one process step. The procedure can be classified between deep drilling and extrusion. Compared to these techniques the advantages are the well controllable structure formation and strain hardening as well as the high material utilisation. Single solutions for the rationalisation of production by means of procedure substitution and complete solutions for procedure integration into existing production flows are offered. Based on a holistic process chain analysis, including a process-optimised component design, additional lightweight construction potentials can be made accessible and energetically efficient manufacturing solutions can be developed.

Profile rolling / Gear rolling

The production of gear profiles by forming is realised by a kinematic rolling process and a concurrent feed-depended penetration phase of the tools in radial direction. Especially for rolled high gears there are following advantages in contrast to cutting manufacturing techniques: Hardness increase by strain hardening in the tooth geometry up to 100 per cent Very short processing time Optimised utilisation of material by non-cutting production and minimisation of swarf disposal

Plate-finished flanks (Rz, Ra = 1.0 mm) Contour-adapted fiber structure Rollable part classes are: Cylindrical gears Worms Profiled hollow parts Special profiles

Axial closed die rolling

Axial closed die rolling is a modern manufacturing method of metal working for the production of rotation-symmetrical forgings with and without bore. The procedure is used in all classical fields of cold or hot bulk metal forming. During forming steel materials, the required forming temperature is higher than the re-crystallisation temperature. A broad spectrum of shapes and materials can be formed. Some exemplary investigations on components and tool technology that were completed at Fraunhofer IWU are: Segments for roller bearing production Welding stub for tube industry (CuNi-alloy) Semi-finished parts for hydraulic accumulator production Railway wheels

Cross wedge rolling

In this method of partial forming two wedge shaped tools, moving in the opposite direction, form the workpiece

according to the profile of the wedges producing rotation-symmetrical stepped components. The method can be applied for manufacturing stepped shafts and for mass distribution of preforms for die forging. It is especially suitable for materials with high capacity for elongation and necking. The advantages of the method are high accuracy of mass, shape and tolerances, long tool life and better material usage compared to alternative machining methods. There are two types of cross rolling machines: with flat tools and round tools. Both can be found in the labs of Fraunhofer IWU. The main research is on investigations of the forming behaviour of materials applied for instance in aeronautical and medical engineering as well as on the near-net-shape forming of highly stepped components.

Machine simulation The simulation of complex machine systems is an approach of the theoretical computation and analysis of s t a t i c and dynamic systems. During the simulation experiments with a design model are conducted, in order to gain insights the actual system. The terms ‘system which is to be simulated’ and ‘simulator’ are used as implementation or realisation of a simulation model. A substantial component of the simulation calculations is the determination of input and output factors. The objective is the development of simulation models to illustrate and analyse of behaviour of machines and production systems. Emphases of the investigations are on: Coupling spindle press Drop hammers, counter-blow hammers Tool load during die forging Tool mountings in hammers (fixation by screw-wedge elements)

IN CONVERSATION WITH Dr Nicola Leibinger-Kammüller

We switched from crisis to expansion

overnight … says Dr Nicola Leibinger-Kammüller, President, TRUMPF GmbH + Co KG. With over eight decades of engineering excellence, the company has successfully established itself as the world’s leader in production and medical technology. In an interview with Swapnil Pillai, Dr Kammüller talks about the growing Asian economy.

Q What has been the success mantra

of your company over the years? We have an excellent business year behind us. With 51 per cent growth in sales, it is the highest growth rate in our company’s history; and with order receipts of € 2.2 billion, we have reached a new high. This means that we are back at the same level as before the economic crisis. Within a single year, we have made up for the losses we suffered in the preceding two years. We find that our foreign associates and 50

MODERN MACHINE TOOLS - December 2011

partners ask us again and again: ‘How do you do it?’ ‘What makes German companies so strong?’ One byword mentioned again and again is the ‘German Wirtschaftswunder’ or the economic miracle. The answer or at least a part of the answer is that ours is a family owned company. This means we can permit ourselves the luxury to think about the day after tomorrow. We think about the next generation too; and are not driven by quarterly figures and certainly not by profit warnings.

Dr Nicola Leibinger-Kammüller Instead, we can afford to act in a way that is strategically adept, sustainable, and appropriate for the long run. Let me mention as an example the most recent crisis, the one that started in 2008. In spite of higher labour costs in Germany, we did not lay anyone off. We did this out of a sense of responsibility to our own operations – because we knew we would need those same employees once the crisis is over. We kept our expenditures for research and development high – at a level twice the average for our industry. And in spite of a general hiring freeze during the crisis, we did recruit some engineers. These were recent graduates who were able to start out with us on special terms. That is another reason why – right after the crisis ended – we could go to market with new products and technologies.

Q With the European economy

facing a turbulent period, do you foresee a déjà vu of the 2008 crisis? What preventive measures can be adopted to face a similar situation? During the course of the slump our family invested € 75 million in the company. This was done not out of pressure exerted by the banks, but rather as a signal, directed both inward and outward that we believe in TRUMPF’s strengths. The outcome of all these steps – and of many others – was that we were able to profit from the worldwide growth that ensued immediately after the end of the crisis. That was made possible by our highly flexible production system. We were able to switch it from crisis to vigorous expansion practically overnight. We could ramp up production immediately, keep delivery times short, and in this way acquire new market shares. Expressed in numbers, this means that sales in Germany, our home market, grew by more than 50 per cent in the fiscal year 2010/11.

We were quite successful in the Asian markets and particularly in China, as was true in eastern Europe, too. Bucking the trend in another market, our business grew in the USA, as well, and as our clientele there is strongly exportoriented it is profiting from the boom in Asia.

Q What are the company’s future

expansion plans? Southern Europe’s markets are actually quite significant for us- Spain and Italy being two examples, but they are limping behind this trend. We are hoping for an upturn especially in Spain following the upcoming elections. Our plans are to pursue expansion in the growth markets and particularly in China. We are assuming continued vigorous expansion as the industrialisation of the vast western regions in China is yet to take place. That is why, we are doubling the capacities of our plant in Taicang, near Shanghai. The new structure being built there will be dedicated in February 2012. This will also be flanked by reinforcement and expansion of regional sourcing. We are planning investments at many other locations, as well: In Ditzingen we are erecting two pre-fab buildings to quickly augment capacities for laser technology and mechanical engineering activities. In Schramberg, in the Black Forest, a new development center is now under construction. In Hettingen, also in Germany, we are building a new structure for final assembly of machine tools. In the town of Saalfeld, Thuringia, two additional bays are being erected for the medical systems subsidiary. Operating tables will be manufactured there. In Grüsch, Switzerland, a new manufacturing building for marking lasers is being planned; and In Princeton, New Jersey, a new clean room for diode production is now being set up.

Q Share your strategy for unprec-

edented growth. All these expansion plans are because we believe that growth will prevail. It is true that we are expecting the business cycle to level off somewhat but, we are still projecting a double-digit increase in sales. That is because we have the appriopriate high-efficiency products, with which our customers can achieve advantages vis-à-vis their competitors. That was decisive for our clients during the downturn and that will continue to be crucial in the future. At the same time we are continuing to put our faith in R&D. Some 1,200 employees are at work in these fields across the globe. This is in line with our objective of always being a step ahead of our competitors in terms of technology. We also provide our customers with direct consulting on applications and custom development work. Our Laser Application Center (LAC) is a concept – to develop solutions in the field of laser technology for the customer and in close co-operation with the customer – is, to the best of my knowledge, unique. At present we have six such LACs – in Germany, US, Japan, China, Taiwan and Korea.

Q Tell us about the strengths of

your organisation We draw our strengths from the interplay of commitment to the domestic market and an international outlook. BadenWürttemberg is the best place in the world to build machine tools. Many subcontractors are located nearby and that enables close collaboration not only in production, but also in development work, to mention just one example. An excellent network of colleges and universities as well as superbly trained technicians and engineers complete the picture. But the rest of the world is no less important. We have had and still have the courage necessary to launch activities in promising markets, wherever they might be. Our slogan is: Swabian. Global. That’s the way we think and that’s how we operate. swapnil.pillai@infomedia18.in

December 2011 - MODERN MACHINE TOOLS

Splashing cutting-edge performance Cutting fluids have been extensively used in metal cutting operations over the last 200 years. As cutting operations became more relentless, cutting fluid formulations became more complex and an indispensable part of modern-day machining. In this backdrop, manufacturers are gearing up to develop products that are economical and offer high-cutting performance, while, at the same time, being in tune with the environment, writes Nishant Kashyap.

odern-day cutting fluids are special blends of chemical additives, lubricants and water, formulated to meet the performance demands of the metalworking industry. They are used in machine shops to improve the tool life and functioning of cutting tools. Cutting fluid is also a key factor when it comes to machine shop productivity and manufacturing of quality machined parts.

Types of cutting fluids Several types of cutting fluids are available in the market today. The most common 58

MODERN MACHINE TOOLS - December 2011

among them can be broadly categorised as cutting oils or water-miscible fluids. Water-miscible fluids, including soluble oils, synthetics and semi-synthetics, are now used in a majority of applications. Although straight cutting oils are less popular than what they were in the past, they are still the fluid of choice for certain metalworking applications. Cutting fluids play a significant role in machining operations and impact shop productivity, tool life and quality of work. With time and use, quality of fluids degrades, and eventually requires disposal once their efficiency is lost. In recent times, when machining

process has become more sophisticated, the cutting fluids and coolant industry also needs to provide new cutting-edge solutions. According to Pratap Marathe, Managing Director, Pratap Tex-Chem Pvt Ltd, â&#x20AC;&#x153;The cutting fluids industry is growing alongside the automated machine industry, as both go handin-hand. Conventional cutting fluids had low productivity and speed as the mineral oil content in these fluids was high. It also had little margin to accommodate lubricating, emulsifying, anti-bacterial additives. So it gave way to semi-synthetic coolants, which have low content of mineral oil for better

SPECIAL FOCUS Eco-friendly Cutting Fluids

Eco-friendly Cutting Fluids fluidity, high quality biocides for long sump life, lubricants for better tool life, emulsifiers for cleanliness of machines, demulsifiers for better tramp oil rejection, etc. to enable more speed and better productivity.”

Choosing the right cutting fluid Choosing the right metalworking fluid for operations is a herculean task and time-consuming too. In order to select a fluid for a particular application, advantages and disadvantages of metalworking fluid products should be compared through review of product literature, supplier information, and usage history. Product performance information shared by other machine shops is another means of narrowing choices. Ultimately, the best indicator of fluid performance is through actual use. When choosing fluids, it is imperative that one should get value for money. During fluid selection, the benefits of fluids and their versatility should be weighed against its performance in each metalworking application. Because of significant improvements in fluid formulations, fluids available today are capable of handling a wide variety of machining applications. “Mostly semi-synthetic coolants or metalworking fluids with Extreme Pressure (EP) additives are being used while machining hard components made of titanium and soft components like aluminium. These EP additives help in reducing friction between tool and titanium components and provide proper finish. Similarly, it helps for aluminium, which is comparably soft and melts even at low temperatures. These EP additives increase chip welding property of the coolant, thereby giving good finish and fast removal of chips from the tool that eventually increases tool life.” Machine shops that once required several types of fluids may now find that one or two fluid types meet their needs. Consolidating the number of fluids used in the shop simplifies fluid management.

Challenges abound The growing concern towards environment has forced companies to adopt green solutions. But the awareness level on availability of ecofriendly products is low. Coolants are increasingly utilised to contain the heat generated during machining. Marathe says, “Many customers are not aware of the advancements in the coolant industry, which are mainly aimed at environment safety. So there is a need to educate and convince customers to adopt these advanced technologies.” Another challenge faced by the industry is the ever-growing cost of coolant. Different kinds of cutting fluids are required for various applications. Machine tool builders are looking at solutions, which are not only environmentfriendly, but also increase tool life as Pratap Marathe, Managing Director, Pratap Tex-Chem Pvt Ltd The most challenging aspect of this industry is the ever-increasing prices of base oil and raw materials. Due to this, it has become difficult to offer good quality coolants at reasonable prices.

well. “The most challenging aspect of this industry is the ever-increasing prices of base oil and raw materials. Due to this, it has become difficult to offer good quality coolants at reasonable prices. Many small companies cannot survive this situation and eventually phase out of the competition posed by branded companies,” avers Marathe.

Environmental aspects With emphasis on reduction of carbon footprint, several manufacturers are experimenting with vegetable oil-based coolants in their day-to-day activities, as mineral oil and synthetic alkane are not appropriate to be used as the base oil for environment-friendly cutting fluid. According to Marathe, “Selection of base oils and additives to ensure environmental

Factors to consider during fluid selection

Cost and life expectancy Fluid compatibility with work materials and machine components Speed, feed and depth of the cutting operation Type, hardness and microstructure of the metal being machined Ease of fluid maintenance and quality control The product’s applicable temperature operating range

aspects is an important factor, as it has become absolutely necessary to pay heed to nature and deteriorating environment. So, manufacturers have to stay updated on the developments happening in this field. For instance, gradually the industry is implementing the usage of esters and naphthenic base oils instead of gum rosin and conventional base oils, respectively, as they are easily disposable and less harmful.” Across the world, many countries have been establishing regulations to reduce the environmental impact of industrial production, and as a result environmentfriendly lubricant alternatives are sought. Waste management and disposal have become increasingly complex and expensive. Environmental liability is also a major concern with waste disposal. “The latest advancement in this regard is the usage of synthetic esters instead of mineral base oils to conserve the decreasing crude oil stocks. So we can divert these stocks towards making fuel for vehicles, aircraft, etc. Synthetic esters have single boiling point unlike mineral oils that have variable boiling points, and at elevated temperatures, provide excellent lubricity with less evaporation of coolant,” concludes Marathe. Since metalworking industry demands environment-friendly, cost-effective solutions, coolant industry constantly needs to improve its products with such additives that will reduce heat generation and biocides to control the bacterial growth and wastage, as well as increase the tool life and sump. December 2011 - MODERN MACHINE TOOLS

Liquid solutions for airborne machines Safety is synonymous with quality in aircraft production. Greater productivity must never be at the cost of quality. Dependably meeting such high-quality standards demands an optimal cutting fluid for each application. However, to attain the highest quality, innovative solutions are required for machining today’s tough and costly aircraft materials at high removal rates.

achining titanium and its alloys has long been the subject of diverse innovative projects, but there is still a great deal of optimisation potential. While difficult to machine, titanium is an increasingly important material in various industrial segments – above all in the aerospace industry. Titanium is strong, lightweight and highly resistant to corrosion. It also has an extremely high melting point – all of which makes it extremely useful in aerospace engineering. To machine titanium successfully, various challenges have to be mastered. Not only does titanium have a thermal 60

conductivity three times lower than steel, but also a low modulus of elasticity and a pronounced tendency to stick. Heat has to be removed via the cutting edge and the workpiece rather than through the swarf as with other materials. This means that the workpiece is subject to extreme thermal loading, so that cutting fluid with efficient cooling properties is required in large quantities. All in all, this places high demands on the cutting fluid.

The role of cutting fluids Today, more and more aircraft components are made of composite

materials such as Glass Fibre Reinforced Plastics (GFRP), with excellent strengthto-weight and density characteristics. Machining modern materials like GFRP, inconel or titanium in large quantities requires innovative high-performance machinery, tools and cutting fluids. Cutting fluid plays an important role in the machining process as a whole. With demanding materials and machining requirements, the cutting fluid has a measurable influence on productivity. This really shows up the quality difference between cutting fluids. Furthermore, optimal cutting fluid feed is decisive for successful machining, often requiring large flows at high

Metal Working Fluids pressure. As a rule, the cutting fluid is fed through the tool. This is only possible at high pressure. Moreover, the mechanical feed pressure loading must not generate any foam, which negatively affects machining by dramatically reducing cooling and lubrication, and the cutting fluid must remain stable. In order to stay on the cutting edge of technology and keep up with customer innovations, experts work in innovation networks where strong complementary partners in the process chain â&#x20AC;&#x201C; machinery, tool and cutting fluid producers, material suppliers and software providers â&#x20AC;&#x201C; bundle their individual skills to master new challenges. Pocket-milling titanium is one of the commonest machining tasks in the aircraft industry.

Driven by passion and perfection, this international sporting extravaganza is a shot at millions earned through advertising, sponsorship and broadcast revenues. Swapnil Pillai talks about how the manufacturing industry is now waiting in the wings to grab this opportunity and earn millions using men and machines.

everal industries incorporate the technical achievements originally developed for space exploration. But the technologies used in Formual 1 racing industry are so advanced that they have proved to be an inspiration for space scientists who have adopted these latest technologies from this advanced sport. Construction of Formula 1 race cars is unique. The industry requires high performance precision driven machines to produce lightweight frames that glide the machine, highly sophisticated engines & components (more than 6,000 74

components are used in a Formula 1 car) and tyres that withstand the powerful movement on the circuit. According to Samir Kumar, Regional Manager, Tungaloy India Pvt Ltd, “This is a low volume high precision industry. To reduce the weight of the car many special materials like titanium and aluminium special alloys are used.”

Benchmarking innovations: A Formula 1 racing team’s annual budget is estimated at about ` 750 crore, of which, about 70 per cent goes in research, development and production of the car.

The leading Formula 1 teams have expanded their design, engineering and R&D departments in the last decade, as the requirements have expanded and large budgets have been acquired to finance them. Vineet Seth, Managing Director - India and Middle East, Delcam Plc, UK, says, “The Formula 1 car per se, is a piece of technological ingenuity and is quite unlike any generic automotive vehicle that we see or use. What sets it apart is the precision and eye for detail for everything, which most automotive manufacturing process are a bit lenient on.”

Business Opportunities The success in Formula 1 also depends on a highly skilled team of designers and engineers. The industry requires very high caliber people, in most cases, possessing relevant degrees from universities of the highest quality and reputation. Though India has the highest number of qualified engineers around the world, necessary exposure to this highly technical job becomes imperative. Concrete initiatives taken by premier educational institutions in the country to impart these technical training will enable India to better serve the industry. “A close relation with not only premium but, enthusiastic academic institutions is required to ensure that the human skills element is added to the mixture that is efficient engineering. The silver lining currently, is that quite a few organisations are heading in this direction. The CII and IMTMA are a few organisations who have tried to educate and nurture the Indian machine tool industry as well as SMEs in various training programmes related to Machining and Quality control – and this has brought fair results already,” says Seth.

The Indian edge The Indian automotive industry which is currently one of the fastest growing in the world has been successful in establishing itself as the hub for small car manufacturing in Asia. It is also a major hub for manufacturing competitive auto components especially metal intensive components: forgings, stampings and castings. Seth says, “The core of automotive and auto sport – the engine, transmission and aerodynamics

are still critical manufacturing processes – and thankfully, many Indian suppliers to automotive OEMs are well known in this line of business.” Auto component industry in India has potential to grow at a Compounded Annual Growth Rate (CAGR) of 13 per cent to reach $ 40 billion by 2015. This is supported by the burgeoning Indian machine tools industry that manufactures almost the complete range of metal-cutting and metal-

It will work out much cheaper for Formula 1 racing teams to develop required parts in India. According to P J Mohanram, Senior Advisor – Technical, IMTMA , “With the successful conduct of the Delhi F1 race, India can bid to take a part of the business opportunities that F1 offers. For this, the best machine tools and a highly skilled workforce have to be got together. F1 manufacture is highly knowledge based, and even the machinist must be aware of the importance of the part s/he is making, and the vital role of precision. There is no room for errors. It is a challenge, but one that can be taken on by Indian manufacturing industries.”

Focus areas for shop floor forming machine tools. “The Formula 1 car is made up of exotic materials such as carbon fibre composites, lighter but stronger alloys etc. Machining such materials require extensive capabilities in machine tools, cutting tool materials – as well as for CAM programming. Good news – this current technology is very much available in India, as well as in use at many automotive OEMs and their supply chains.” continues Seth. Efforts within the industry are now underway to improve the features of CNC machines, and provide further value additions at lower costs, to meet specific requirements of the industry. Samir says, “In India we have the required machinery and tools available. The concept of machining remains the same but the accuracy levels and the work material will change which, I feel can be done. Here the main thrust will be on the machining of cylinder block, cylinder head, crankshaft, camshaft and other transmission components.” The labour intensive market of India that offers skilled manpower

“Formula 1 cars will not be a commercial ocean in themselves. But the performance standards they set, the technologies they spin off will benefit the automobile industry as a whole. Not only automobile, even the machine tool industry with get benefited by designing products that produce components for such high performance marvels. The technologies so developed would benefit high precision, high performance and high speed in various manufacturing processes,” says Shailesh Sheth, past President, IMTMA. The Indian machine tool industry continues to maintain a positive outlook for the future of auto sport particularly Formula 1, and the subsequent benefits on the Indian machine tool sector. swapnil.pillai@infomedia18.in

Formula 1 Material reliability and optimum performance are the key words in Formula 1 car manufacturing. Nishant Kashyap takes a look at why Formula 1 cars are so dependent on the use of advance materials, particularly, fibre reinforced composites.

he use of composite materials for the manufacturing of racing cars was a significant milestone of achievement in the automotive industry. As earlier, racing cars were made mostly with a single aluminum chassis which was prone to major fractures. In the late 1980s, the use of advanced composite material in the racing industry caused a revolution of sorts in the world of automobile engineering. Such composites provided an apt solution for racing car chassis, as these were not only lightweight, but also sturdy and robust, offering the driver much more security if the car were to crash. 82

MODERN MACHINE TOOLS - December 2011

â&#x20AC;&#x153;Aluminum, magnesium and titanium based alloys are the main materials being used in manufacturing Formula 1 cars. This enables them to have engines lighter in weight yet, stronger in performance. The composite technology has already come to India and is being effectively used in the aerospace industry. This will also trickle down into car manufacturing in future,â&#x20AC;? says Tosher Hormusjee, Director, G W Precision Tools India Pvt Ltd.

Importance of composite materials Composite materials, over the years have turned into an indispensible aspect in the production of sports cars, as they are significantly stronger and lighter than

other materials. As a result, the use of a composite material not only decreases the overall weight of the object, but is also, compared to single layered materials, much more break resistant. Composite materials are developed by the combination of two or more materials, with quite different properties. The individual materials, when coalesced together, for an unique material that has indigenous properties. They do not blend in such a way as to loose their individual properties. This is what makes a composite material tougher than the original materials that are used in the composition. High performance race cars and aerospace components manufacturers

New Age Materials demand for materials that are lightweight, as well as, strong enough to withstand harsh conditions, including high temperature and incredible stress and strain.

Materials and analysis A major factor that has led to the expansion of carbon fibre use in Formula 1 is the improvements being made in the materials themselves. In recent years, an increasing number of fibres have been developed. By processing the fibres differently, thinner fibres with much greater tensile strength and modulus have been developed. Here the disadvantages

Formula 1 was one of the breakthrough industries in pushing carbon fibre composite technology. It was the first industry to move away from the welded metallic structures to look at carbon fiber monocoque and fiber tub construction, resulting in a significant step forward in terms of performance than a traditional welded structure would have offered. are that, high and ultrahigh-modulus fibres cost more and are much more brittle than standard carbon fibres. The new ultrahigh strength varieties reduce brittleness and open up a number of applications hitherto precluded to composites, but these come at a high expense. Structural adhesives used to bond carbon components together and to add metal inserts have also improved, extending the number of parts for which it can be used. Similarly the epoxy resin matrices used to bind the fibres together have also improved. According to P J Mohanram, Senior Advisor, Indian Machine Tool Manufacturersâ&#x20AC;&#x2122; Association (IMTMA), â&#x20AC;&#x153;Formula 1 cars are an amalgam of various materials in their parts. Aluminium is used in engines, high alloy steels for the gearbox and transmission, and body parts are made of fibre composites. Machine tools such as turning and machining centres, special machines, gear cutting and finishing machines, tape laying machines, moulding technology and autoclaves for curing composite parts are some of the manufacturing facilities required. Needless to say, these will come from the most reputed machine builders in the world. Formula 1 cars are managed by complicated computer systems on-board, and employ a range of instrumentation and transducers on the vehicle to continuously monitor, control and optimise the December 2011 - MODERN MACHINE TOOLS

Probably the most important change in the use of carbon fibre, though, has been the improvement of detailed stress analysis. The advent of Finite Element Analysis (FEA) coupled with vast increases in computing power, has allowed designers to asses their designs for possible weak points. There are several choices the designer can make at this point. Material can be added to areas exposed to high stresses.

Use of carbon fibre Earlier racing cars used to be made of steel, aluminum and other metals. However, in the early 1980s, Formula 1 underwent the beginnings of a new revolution that has become its hallmark today: the use of carbon composite materials to build the chassis. Around 80 per cent of the car by volume, is carbon fiber composites, but contributes only 20 per cent to the total weight. Formula 1 was one of the breakthrough industries in pushing carbon fibre composite technology. It was the first industry to move away from the welded metallic structures to look at carbon fiber monocoque and fiber tub construction, resulting in a significant step forward in terms of performance than a traditional welded structure would have offered. Composites have allowed manufacturers to get more creative with the aerodynamics of the car, with the complex composite molding technologies. They have also inspired an evolution in the car shape from the big boxy structures to the aerodynamically-shaped cars we have today. Today, most of the racing car chassis - the monocoque, suspension, wings and engine cover - is built with carbon fiber. The most commonly used composites in Formula 1 are continuous fibre, thermoset fabrics and unidirectional fibres fabricated with core materials such as aluminium honeycomb and foam. However, the substitution of other variations of composite materials may form part of the substitution into other industries. While costs may initially inhibit the transfer of techniques and innovations, part of the technology transfer process will follow the reduction of complexity and the automation of the manufacturing value chain. Component integration, structural health monitoring and experimental techniques for certifying composites will increase the confidence of various industries to push the usage of composites further than before, with weight-saving targets in the order of 50 per cent. nishant.kashyap@infomedia18.in

Once this goal becomes a reality, it would eventually be the dawn of a new era in automobile manufacturing. Debarati Basu explores the machining industry’s immense potential to build a Formula 1 car with excellence.

It might be a far-fetched dream; but, with the rapidly increasing technological advancements on the Indian shop floors, this would be an opportunity for the industry to realise its potential. “Designing a Formula 1 car involves high science and technology. It embraces cutting-edge technologies in vehicle and suspension design, light weighting, aerodynamics, materials, composites, simulation using CAD, CAE, CFD etc. followed by wind tunnel testing, test bed, endurance trials and the like.

F3 and F2 cars and then slowly graduate to building high precision Formula 1 cars,” says Tosher Hormusjee, Director, G W Precision Tools India Pvt Ltd. The penetration of aerospace industry into India is also an added advantage for the manufacturers, as aerodynamics form the major link in the manufacturing of such high precision cars as well. This has actually got the Indian manufacturers a step ahead to realise this big dream. “To make an Indian Formula 1 car, the best course would be to make one for a foreign racing team. After the Delhi Formula 1 event, some racing teams have spoken of building their race cars in India. However, this calls for highly specialised skills, and the four Ms – materials, machines, men and money. It is not impossible, but Indian aspirants will have to learn this afresh. It is not generally known that Formula 1 car parts such as valves, seats, manifolds etc. are often hand-finished by lapping, super finishing and polishing operations. Assembly discipline is likewise high. It would be exciting to start the building of Formula 1 cars in India, with a foreign team initially, before taking up an entirely Indian venture. A bulk of research on Formula 1 technology is conducted in the British Mid-lands at specialised facilities. Many are shared between the teams due to their high cost,” avers Mohanram.

Technology at full throttle The lack of volumes for such technology might be a deterrent for the industry to carry out mass production, but research and development on the technology will certainly revolutionise 94

MODERN MACHINE TOOLS - December 2011

this field of manufacturing. However, as the industry gains its acumen in this technology, the shop floor functioning will automatically change. “Although manufacturing does not have the required demand yet, many companies are already taking keen interest and getting involved in the design part of such manufacturing. The R&D in the area of Formula 1 cars is now targeted in such a way that the technology can trickle down in general manufacturing as well,” observes Hormusjee.

P J Mohanram Senior Advisor Technology, IMTMA Building Formula 1 cars in India will have its spin-off benefits on passenger cars manufactured in the country through transfer of technology from Formula 1. The machine tool industry will also benefit through inputs on precision machine building.

The research related to Formula 1 cars across the globe is in the lines of its effective utility in manufacturing of normal cars. While India has created its own space in the industry for manufacturing high precision components, it will be in a position to effectively incorporate the high-end technology in car manufacturing as well. With the technology transfer, the Indian shop floor will undergo a transition in terms of being more reliable with greater tolerance. “Aerospace sector introduced the use of composites in the industry, and today the industry can effectively use hardto-machine materials, which will be an added advantage while machining these high precision cars. Similarly, the knowledge gained by manufacturing a Formula 1 car will help our industry offer global quality products to the market. The technology will result in better tyre manufacturing and braking, thus bringing in higher safety for cars. Engine manufacturing will undergo a

complete transition as the major focus will be on the use of lighter material and fuel efficiency,” reflects Hormusjee.

Engineering refinement As the entire industry is focussing on lowering the fuel consumption by automobiles, the technology transfer from Formula 1 manufacturing will have a big impact on the engine manufacturing. The use of new materials is also changing the manufacturing process, as it will in turn result in lighter and fuel-efficient machines. “The industry will also witness better use of PLM technology, which would stimulate e-manufacturing of cars, thus expediting the entire manufacturing process. All these will certainly change car manufacturing in the country, said Hormusjee. The technologically advanced manufacturing techniques will ultimately change the way cars are manufactured, so that small and mid-sized cars rolled out of the Indian shop floors will also be machines par excellence. “Building Formula 1 cars in India will have its spin-off benefits on passenger cars manufactured in the country through transfer of technology from Formula 1. The machine tool industry will also benefit through inputs on precision machine building. The overall standards will rise, although it will not be entirely due to Formula 1 technology demands alone,” opines Mohanram. Even as high precision sports cars forms a niche market with very less demand in terms of volume and profitability, experimenting with the technology will open up avenues for the Indian industry to become an automotive giant at the global platform. A focused effort to bring in the research and development into the manufacturing fraternity will also instill the high precision machining in the system. The Formula 1 technology will not just reinforce better quality but also filter down the manufacturing cost in the long run, thus changing the entire dynamics of the Indian shop floor. debarati.basu@infomedia18.in

ar racing is a rage among people of all ages, as is evident from the popularity of motorsports all over the world. While the speed and associated danger seem adventurous, the racing car designs are surely worth a mention, which gave rise to some of the best known innovations. As the demand for racing cars increases, so is the need for automation in the manufacturing process. Intense competition calls for reduction in production cost, improvement in customer care, better supply chain management, and effective marketing 96

MODERN MACHINE TOOLS - December 2011

and sales management along with overall business process automation.

Automation leads the race Manufacturing of racing cars is unimaginable without state-of-the-art technology and processes. In addition, suppliers of various parts such as pistons as well as electronic instrumentation to this manufacturing industry are vital in providing the necessary components for assembling racing cars. There are many components, which are costly and need high precision. Some components may require fewer efforts or may be just a

part of the end-product. Manufacturing products with high precision and at a lower cost can be easily done using automated machines such as Computer Numerically Control (CNC) machines as they require little human intervention, thus reducing the manpower cost. Building a race car is where the technology is becoming a new strength. Automation technology has become an essential part of the car manufacturing industry. While this does involve the use of the latest technologies, it is important to be careful especially by taking care of the finer aspects.

CAD/CAM Solutions Designing models of chassis, car body and other components including the engines can be done using CAD/ CAM. The CAD designs allow patterns to be drawn out. The integration with CAM allows machine programs to be written, besides being cut out through CNC machines. This also enables to improve the accuracy and repeatability of one car versus the other.

heavily backlogged and customers were threatening to find a more flexible source. CP-Carrillo took a critical look at its business processes and found that while its proprietary programming was capable of standard machining, the complexity of the market had advanced. This was forcing the company to rely heavily on other CAM software to perform time-consuming manual operations for custom features. Repeat orders with small changes were being completely reprogrammed in the old CAD/CAM system leading to possible misinterpretation while doubling the process time.

As mentioned earlier, CAD/CAM has worked wonders in the auto manufacturing industry. However, for better and effective performance, manufacturers have to ensure that there is seamless integration between the CAD and CAM software. A CAM system usually seeks to control the production process through varying degrees of automation. Each of the manufacturing processes in a CAM system is computer controlled; hence a high degree of precision can be achieved that is not possible with a human interface. The CAM system, for example, sets the toolpaths and executes precision machine CNC programmes for piston getting generated in CAMWorks operations based on the imported design. Some CAM systems bring in CP Pistons had recently acquired additional automation by also keeping Carrillo Industries, a world leader in high track of materials and automating the performance connecting rods.

The companyâ&#x20AC;&#x2122;s order book was LLC and Carrillo Industries, and Karl

Ramm, Senior Technology Manager, CP-Carrillo LLC, wanted to develop an enterprise business process that linked the order taking system with the design and manufacturing processes. They wanted a system that would enable the sales staff to instruct the assembly line and machines on the assembly line to start the order. This would require CAM software integrated into their design software, with customisation capabilities through Application Programming Interfaces (APIs) that could be linked to the ordering system.

The result Today, CP-Carrillo has a master model for designing and manufacturing pistons. It has template libraries and family tables for various types of pistons and has categorised them by manufacturing processes. When an order is entered into the order booking software (essentially an access database), the output from the ordering system goes to SolidWorks whereby the new piston CAD model is generated with the help of design tables and APIs. Then, CAMWorks gathers inputs from the order system and SolidWorks, and generates machine code, which is ultimately sent directly to the CNC machines. CP-Carrillo has now doubled the productivity while ensuring consistency with a small investment in CAM software. A repeat order, even after a few years, will be machined exactly the same way it was the first time the order was processed, using the new integrated system. Now, the next leap is taking automation to a level where a sales team member can directly instruct a job to run on the machines using the order booking system without any intervention from designers and programmers. The race is on for spearheading further developments in automation. Sambit Pradhan, Business Development Manager, Geometric Ltd.

The formula behind an

car

Creating a competitive Formula 1 racing car is a highly pressurising task, which has led companies to adopt the best technology available to build a faster, better and safer car. Software (CAD/CAM) has become the key technology in the manufacturing industry, which is used at every stage of the development cycle – right from creating initial design concepts to supporting the rigorous testing routines and manufacturing processes – only to achieve optimal performance.

esign of a car begins with the overall aerodynamic package and what is referred to as the chassis: the carbon fibre survival cell in which the driver sits. The engine is bolted to the back of the cell and the gearbox attached behind the engine. Systems such as hydraulics and suspension need to fit in and around these components, with the radiators being positioned on either side of the driver.

Unrelenting focus on evolution and innovation “There is no room for complacency in this sport,” observes Christian Horner, Team Principal, Red Bull Racing, after the team finished second in the 2009 Championship. As he spoke, the team was already manufacturing its 2010 car, because Formula 1 success demands an unrelenting focus on evolution and innovation. “We talk about racing ‘cars,’ but they cannot really be compared with what 98

we drive on a normal road,” comments Steve Nevey, Business and Technical Development Manager, Red Bull Racing. “The flow of air over, under and through a racing car determines its ultimate speed and the way it functions, for example the engine is fed and cooled by airflow. The emphasis on aerodynamics and weight means that we are designing and manufacturing technical machines that are closer to an aircraft than a saloon (sedan) car. They are finely balanced to begin with and then continually

refined for speed and accuracy.” Red Bull Racing’s development process has to be as swift and precise as these amazing vehicles and the company relies on NX™ software for CAD/CAM/CAE and Teamcenter® software to capture and manage knowledge. It is a creative and collaborative, virtual world from which the real, live car emerges almost fully formed and ready to be put to test on the

track. “We call it our digital backbone,” says Nevey. “NX™ and Teamcenter® sit at the heart of the company and they feed data to our manufacturing facilities; we could not manage without them.”

Rigorous and dynamic regulations Formula 1 regulation is refined each year and the design has to meet rigorous criteria. Major changes were instituted for the 2009 season and one of the challenges for 2010 was how to manage

the ban on refuelling during the race. This means that suspension, transmission and braking systems all have to be fortified to carry a high-capacity fuel tank that is longer, wider and heavier as it must carry twice as much. A continuing requirement for 2010 is that the gearbox has to last for four races so, with the additional fuel, it has to be even more robust, yet as light as ever.

INSIGHT & OUTLOOK High-speed Automation In addition, the Restricted Resource Agreement introduced by the Federation International de l’Automobile (FIA) is essentially a budget cap, which means that overall efficiency in the design and production process needs to be at the top of the agenda. The design also has to accommodate the unique properties of each Grand Prix location. Clearance from the ground, known as ride height, is on an average 5-6 cm, but this figure needs to be varied according to the relative smoothness of the track, as does the stiffness of the suspension. Aerodynamic downforce, which pushes the car onto the ground, also needs to be modified via wing size and angle. On bumpy, twisty circuits such as Monaco, where downforce is critical, the wings need to be higher. On circuits where there are many straights, such as Monza, the wings can be shallower to support sprinting. Nevey notes, “It is a constant battle between downforce and drag.” The car is therefore designed as a complete kit: a core product with a range of interchangeable parts that act as alternative build options for different types of terrain. “We end up with a huge bunch of bits,” says Nevey. “We initially had a dilemma as to what actually constitutes a Bill of Materials (BOM). After considering our options we decided to think in terms of the whole BOM, so instead of creating different suspension assemblies, for example, we have one that incorporates different springs, dampers and roll bars.”

Race, review, modify and manufacture – all in a week’s work In addition to planned adjustments, the design team of 180 NX users is on the alert to make performanceenhancing modifications after every race. There is a continual fine-tuning of the design and any amendments have to be driven from the discussion stage through implementation, testing and manufacturing in the space between races. Sometimes this can be as little as one week and parts are often carried to the circuit within hours of the starting 106 MODERN MACHINE TOOLS - December 2011

lights going out. There is no room for error or delay. “NX allows our 180 designers to operate in a virtual world, saving time off at every step,” says Nevey. “NX is an excellent NC programming tool and members of Siemens’ professional services team have been brilliant at helping us to get the most out of our tools. They have, for example, Race bays at Milton Keynes Factory, where all the parts are demonstrated how to make assimilated the most of parametric modelling when we are still at the experimental stage and how to adopt new methods. One of these is the use of stereolithography whereby CAD data is used to ‘print’ on a tank of liquid resin, solidify certain areas and build up a 3D prototype by creating successive layers.” Size is significant.

ahead to the

precision lap

With a triumphant start, amid fanfare and apprehensions, India’s Formula 1 debut was a crowning glory for the nation. But this success is not all about making a grand entry into this revered motorsport; it is about the implications this will have on various industries, be it automotive, machine tools or the manufacturing industry at large. Cashing in on the emerging opportunities are technology providers by offering reliable solutions for aiding machining excellence, precision and acquiring the required finish of components among others – vital for a perfect race car.

ith the Formula 1 debut in India this year, most wonder what the fuss is all about, and how it would benefit the country. The answer to this question, especially for the machine tool and manufacturing industry per se, is the elevation in quality standards and eye for detail in manufactured components. To elaborate further and to give a perspective on the aforesaid statement, it is important to understand how all this would actually be practical someday. Traversing back 50-60 years, it can be seen that the automotive industry was mainly dependent on imports, and Completely Knocked Down (CKD) units, which were assembled locally. However, with the Joint Ventures (JVs) of the early 80s and the continued focus on ‘industry clusters’, it became possible to kickstart an indigenous automotive industry, particularly in the passenger car segment, and the rest is history. India has now emerged as a nation, with better infrastructure, a conducive environment and adequate resources to take on most 108 MODERN MACHINE TOOLS - December 2011

other precision manufacturing such as that of the aerospace and motorsport industry.

Advancing to the fore The best part – many global technology leaders have set up direct operations in India, thus reducing whatever gap there was in lead-times. CAD/CAM software is already used by several leading manufacturers in the auto sport industry to help them maximise quality and reduce lead-times, both essential requirements for suppliers in this demanding sector. Delcam is leading the way by offering state-of-the-art solutions to these manufacturers. Its PowerINSPECT – a CAM to Part 3D inspection software was adopted by Force India F1 team’s engineering – based at Silverstone, Northamptonshire in the UK. The biggest challenge for the team was to inspect as many components as quickly as they could to ensure that their race car complied with all existing standards, and also performed well in the wind tunnel test, in the shortest possible time. By using PowerINSPECT, they now get better accuracies in alignments,

and also save over 60 per cent in measurement time, in comparison to previous methods. In addition, to keep motor racing as safe as possible for both drivers and spectators, the Fédération Internationale de l’Automobile (FIA) strictly enforces a wide range of safety regulations. At the same time, all participants must adhere to a large number of technical requirements to ensure that no team gains an unfair advantage over other competitors. A combination of Krypton’s Rodym optical co-ordinate measuring system and PowerINSPECT software has been selected by the governing body of Formula 1 racing for all pre and post-race inspection of Grand Prix cars. Technical staff from FIA uses this combination to check that the cars meet both safety and technical specifications. After all the qualifying sessions, the leading cars are inspected with the system.

held probe that can reach into all the regulated areas of the car. The location of the point of contact is measured by means of optical triangulation to calculate the position of the probe tip to within 0.1 mm. Each measurement is then fed into the PowerINSPECT software to determine whether the point is inside or outside the legal limits. The results are displayed instantly, allowing additional measurements to be made in any area of concern to the inspector. The inspections are repeated on each car before the start of the race. Once the race is over, a further comprehensive examination is made of the three leading cars and a less detailed inspection carried out on the next three cars. For more than a decade, every race car has been dimensionally checked before, and some after, qualifying runs and races with templates of its required shape created from production vehicles. The biggest challenges with templates are translating dimensions taken from the automakers’ ‘submission’ vehicles (and CAD models) into the silhouettes of the templates – plus duplicating them, getting them into the hands of the teams and sponsors, and checking them periodically. A few years ago, variations in a race car’s length or profile might be as much as an inch. Now with many teams using new-age technology, a worthwhile competitive advantage may be gained by altering the profile of a hood or bumper by as little as an eighth of an inch. 110 MODERN MACHINE TOOLS - December 2011

Before the race car is even ready to be inspected, there are a lot of manufacturing stages that are required to make the components, and the car itself. Using Delcam’s PowerMILL to program its Bostomatic 505 five-axis machining centre lets Wegner Motorsports turnaround a set of performance cylinder heads more rapidly while improving surface finishes. While it used to take between 20 and 26 hours with multiple set-ups on a threeaxis machine, a set of ports can now be machined in 45 minutes.

Casey Wegner used PowerMILL to reduce port machining time by over 25 hours and now completes a set of ports in just under an hour

A big part of Wegner’s success recently is CNC cylinder head porting. The first step is hand grinding by an expert, a process that combines experience, craftsmanship and persistence. The difficult part is maintaining the consistency in each head, so that all have the same finish. Once the ports have been created manually, the inside surfaces are scanned and the resulting Nonuniform Rational Basis Spline (NURBS) file brought into PowerMILL. Within the software, Wegner engineers specify tools, create toolpaths and check for clearances. Within one to two days, an entire set of cylinder head ports can be recreated from an original as well as machined, tested and installed into an engine.

machining dimensional inaccuracies, location of components for machining, etc. The PowerINSPECT on-machine verification software assists them in composite machining – while delivering higher accuracies and smaller lead-times. With composites, machined holes and pockets tend to be undersized because the material relaxes when it is cut. This effect is difficult to predict because it is impossible to cut all the fibres in the same orientation. To overcome this problem, the initial machining operation is followed by an inspection on the machine tool with PowerINSPECT. This shows how much more material needs to be removed and enables the required extra toolpaths to be generated in PowerMILL. For a typical component, with between 20 and 30 holes, a further cycle of inspection and machining may be needed to produce all the dimensions to the required tolerance. However, for subsequent parts, the complete machining sequence can be repeated and the results checked with a final inspection. Apart from the increase in accuracy possible with this approach, another big benefit is that all the machining and inspection can be completed on the machine tool on a single fixture. It is impossible to maintain the necessary tolerances when moving between a series of fixtures, while using multiple setups on different fixtures would also take much longer. The first set of seventeen components produced with this method was supplied to one of the Formula 1 teams and fitted onto the car with no clashes or rework. It was the first time in the team’s history that this had happened with any set of composite parts from any supplier. This shows how high degree of collaboration among the race team’s engineering, suppliers as well as technology providers propelled them to a growth previously unachieved. The time is now right for the manufacturing industry in India to move to higher grounds.

Creating history With the requirements of a lighter race car, composites have become an irreplaceable material for various components within the car. Composites machining poses many challenges, in relation to post-

This requires high speed machines delivering high precision. Machines used for Formula 1 components are multi-axes machines (5 axes typically) to machine the various features on the components. Gear cutting and finishing machine are important in Formula 1. Typical parts tolerances are in the micron range, and sometimes hand finishing is necessary to fit parts together just right!

Faith in the new idea can be established when ample information is sought and provided. The recently concluded Formula 1 racing poses a new opportunity for the machine tools sector in India. Also, for every machine tools manufacturer or component and service provider to get enthused about this opportunity, it is important to address and satiate all the probable doubts. Hereâ&#x20AC;&#x2122;s bursting some doubt bubbles for you.

Appropriate machine tools will enable accurate machining of parts, thus realising the parameters set by the designers. Functionally, this means that valves seat and seal perfectly, inlet and exhaust ports function with smooth surfaces and contours to obtain perfect combustion and torque/power output, gears mesh and shift at high speeds without failure etc. Friction losses are minimised, so that maximum power is delivered to the wheels. Formula 1 car engines run at 20,000 rpm typically, and it is extremely important that parts assemble exactly and run at the high operating temperatures with no vibration and minimum friction. Only the most accurate machines can deliver such parts for assembly on Formula 1 cars.

Gearing up for zero failures To produce accurate parts for Formula 1 cars, the machine tools must be proven for their geometrical, positioning and machining accuracies to the highest standards. The number of parts produced in Formula 1 is not high, but part-to-part consistency is extremely

Expert Insights important. So the machines must be calibrated for their precision periodically at short intervals. Use of the best cutting tools is important as well. As in the case of aero-space, ‘traceability’ is important, and in case of failures, it must be possible to trace what caused it, and what part of the manufacturing cycle was responsible. So production logging is a crucial aspect while producing Formula 1 parts. Raw material must be likewise inspected and certified before use. All these steps will together lead to zero or near-zero failures.

The machine tool industry will also benefit through inputs on precision machine building. The overall standards can be expected to rise, although it will not be entirely due to Formula 1 technology demands alone.

To make an Indian Formula 1 car, the best course would be to make one for a foreign racing team. After the Delhi Grand Prix event, some racing teams have spoken about building their Formula 1 cars in India. However, the skills for this are highly specialised in terms of materials, machines, men and of course money! It is not impossible, but Indian aspirants will have to learn this afresh. It is not generally known that Formula 1 car parts such as valves, seats, manifolds etc. are often hand finished by lapping, superfinishing, polishing operations. Assembly discipline is likewise high. It would be exciting to start the building of Formula 1 cars in India, with a foreign team initially, before

Measurement technology is crucial for Formula 1 parts manufacture. Tolerances are tight, in the micron and sub-micron range. The most precise instruments and measuring machines are required. Most are electronic and use extensive software to measure all aspects of size, form and finish to sub-micron accuracy levels.

It is a ‘material’ world Formula 1 cars are an amalgam of various materials in their parts. Aluminium is used in engines, high alloy steels for the gearbox and transmission, and body parts are made of fibre-composites. Machine tools such as turning and machining centres, special machines, gear cutting

F1 cars will require automated machining and processing. However, since the volumes are low, automation in the conventional sense of handling and transport are not required. The entire car assembled weighs around 650 kg, and body parts are so light that they are lifted by hand and assembled, even in the course of the race.

Formula 1 racing flags big business opportunities for the Indian machine tools sector With the successful conduct of the Delhi Grand Prix, India can bid to take a part of the business opportunities that Formula 1 offers. For this, the best machine tools and a highly skilled workforce need to be brought together. Formula 1 manufacturing is highly knowledge based, and even the machinist must be aware of the importance of the part s/he is making, and the vital role of precision. There is no room for errors. It is a challenge, but one that can be taken on by Indian manufacturing industries. However, the F1 field does not guarantee profitability! It is more a passion, than a strict business venture.

Workholding Equipment The industry needs to look beyond and have a futuristic approach.”

Key to optimum machining When it comes to adopting cost effectiveness in the manufacturing process, work holders are probably the first element to be compromised on. A major portion of the Indian industry today is accustomed to using the conventional clamping devices and very little thought is given to the inclusion of new technologies evolving across the globe. Elaborating further Sadashivan says, “Innovations in the market happen as per the requirements of the industry. There are different types of components being machined today. Apart from the standard components, there are also delicate and high-precision components. Conventional workholding devices do not meet the precision required to clamp such sophisticated components. For this, the industry has been constantly working towards innovating better work holders.” The global market, however, has evolved and innovations have reached unimaginable heights to develop perfect workholding solutions for manufacturing.

Changing with time Innovations in the manufacturing sector and emerging complexities in machining offer an impetus for improving clamping devices. From using sophisticated materials with complex designs to manufacturing micro-sized tools for performing intricate machining, work holders have undergone a transition to meet the required demands of the industry. A look at the various clamping solutions this segment has come up with for the industry over the yearsMechanical Vices: They are one of the most preferred clamping solutions in the industry. Mechanical workholdings today involve complex fixtures at par with the machines being used in the industry. Commenting on the same Lajpat Rai, MD, Airtech, Dharwad, says, “Dimensional part tolerances will be tighter than they are now. As designers strive to make machines run faster, last longer and perform more accurately, the

demand from a chuck for precision is also likely to grow. An expensive CNC lathe cannot afford to have a workholding device of inferior quality. An inaccurate chuck will result in inaccuracy in the component machined.” Magnetic Chucks: This technology has brought in a revolution in clamping solutions. Even though the technology had various limitations, research in this segment has overcome most of the hurdles so as to be recognised as one of the most reliable form of work holders. “The use of magnetic technology has been a revolution. Magnetic clamping can effectively clamp ferrous materials and unless the component is very asymmetric or with intricate and complicated geometries, which compromises on the area of contact, magnetic clamping today form the best solution to clamping. However, magnetic clamping is yet to find acceptance as an innovative workholding technology,” adds Sadashivan. Vacuum clamping: The rise in the use of sophisticated materials has given vent to the industry to explore areas where effective clamping can be done by vacuum. This technology is optimally being used in aerospace machining where clamping of delicate material requires a solution beyond conventional technology. While research in this technology is going on across the globe, India is yet to pick up momentum in using vacuum as a new clamping solution. Ice clamps: If vacuum is still not the solution, ice clamping is the answer. This technology is picking up momentum globally where highly delicate machining of components with irregular shape can be clamped using ice. The technology, though nascent, has opened up avenues of going beyond indescribable solutions. Ice clamping provides the flexibility of clamping any component with any intricate structure and also providing the advantage of clamping the component from every direction hence, assuring strength during the machining process. Technology evolution in this segment is inexhaustible. But a careful section of the correct workholding equipment

as per the machining specification will ensure optimum results. The industry, instead of relying on standard devices, should focus on customised solutions, which would ensure the best use of technology.

GenX solutions The main driving force behind evolving technology in workholding solutions is to provide better grip on the component, minimise the set up time and increase the productivity with minimal error while machining the component. The growth of various segments of the industry and demand for high-volume production also has a major focus on having lithe clamping devices, which proves to have quicker change over time of a tool from one job to another. Automation on the shop floors also emphasises on this need for having clamping solutions, which can comply with the speed of various manufacturing processes. Expressing his views on the same, N Sriramulu, President, ITW Chemin, elaborates, “The industry is becoming very competitive mainly because of cost fluctuations. We need to be working on our toes as opportunities in this segment are plenty. People are coming up with new models of machines and cutting tools, which offer us vent to innovate. Gone are the days when huge volumes justified investment. People are looking into the concept of cell manufacturing. In the new age workholding equipment, chucks and fixtures we are trying to reduce the set up change time, increase the productivity without compromising on the quality and eliminate unnecessary pre-machining operations. Today, we are trying to convince the customers that instead of two machines the same work can be done by one machine, thereby reducing the cost in terms of manpower, overhead costs, etc. There is a lot of competition in this segment.” After vacuum and ice, this industry is looking forward to even more flexible work holders, which would ensure optimum clamping of any given component with any given shape. debarati.basu@infomedia18.in

Amid various types of workholding equipment available in the market, magnetic clamps are still an untapped area. Even though this technology is not new, the usage of this type of workholding devices is still sparse in the industry. Vijay Sarda, Director, East Coast Magnets tells Debarati Basu that this is the best time for the industry to explore magnets and enhance better grip for precision machining. Excerpts.

Q Magnet â&#x20AC;&#x201C; a better solution for

workholding tools

Vijay Sarda, Director, East Coast Magnets

It is the question of acceptability of new technology 128 MODERN MACHINE TOOLS - December 2011

There are different types of clamping devices in the market like mechanical vices, conventional clamps, hydraulic clamps and vacuum. But magnetic clamps are still one of the most unexploited technologies in this industry. Over 60 years back, magnetic clamps were used only in surface grinding machines as that kind of machining required very light cutting. Today, magnetic clamps are being effectively used for clamping jobs for any kind of machining. There are two essential things required for magnetic clamping â&#x20AC;&#x201C; the job has to be on the bed and obstructions between the clamp & the material should be minimal. In other types of clamping devices, the machining required near the clamping area cannot be done perfectly as the clamps, which hold the job, add to the obstruction. However, magnetic clamps ensure clamping of 100 per cent area of the job without intruding in the machining process. As a result, the entire material can be machined easily from any given angle.

many advantages; the only drawback being the fact that it cannot clamp non-ferrous materials. Apart from this, power failure also poses a major constrain for power magnetic chucks. Additionally, continuous flow of current generated heat can cause deformation of the material, which would translate into inaccuracy in the final machined product. To overcome these issues, the industry later came up with electro-permanent magnetic chucks. These chucks have the safety of the permanent magnets and advantages of electromagnets. The biggest advantage in these new chucks was the fact that electricity needs to be passed only for two seconds. So, in the cycle time of an entire machining process, the power consumption is for two seconds in the beginning to clamp the tool and two seconds in the end to send a reverse current, which would release the material. This process saves power. Depending upon the job, various types of magnetic chucks have been developed today.

Q Overcoming challenges Q Use of magnets as a clamping

device over the yearsâ&#x20AC;Ś The industry initially used permanent magnets for clamping. While these were easy to use, they had the drawback of size, considering that they had to be moved manually. These magnets were later replaced with power magnetic chucks, which were electro magnetic in nature and could be manufactured in any size. The use of magnets has

Innovations to overcome the drawbacks of magnetic chucks are developing at a rapid pace. Various factors are being taken into consideration, especially while machining, to make magnetic chucks suitable for providing optimum clamping in any given situation. We were among the first Indian companies to patent solid top magnetic chucks, which eliminated the damage of epoxy due to overheating.

Industry Views Machining cannot be restricted to ferrous applications. The industry today is using various types of ferrous and non-ferrous materials as per the machining need. We have developed one of the most advanced technologies in magnetic chucks, whereby ferrous materials can be directly clamped, while non-ferrous parts can be clamped in the T-shaped slots. Also, the need to clamp uneven jobs is being met by fixing spring blocks on the magnetic bed, which would adjust according to the uneven shape of the material being machined.

Q Tackling competition In the industry today, magnetic clamps form only around five per cent of the various types of workholding devices in use. This means that this segment has huge scope for development considering that 95 per cent of its potential is yet to be tapped. This technology definitely needs more exposure in the industry. Even in the global market, these clamps are not very popular. However, the industry is now eventually confronting the fact that labour and space are the biggest factors affecting manufacturing today. People in the industry do not have adequate knowledge about this form of clamps and instead, opt for conventional devices. However, more exposure and training can change the perception and gain wide acceptance for this new technology.

Q Magnetic clamps vs. conventional devices The main advantage that magnetic clamps provide is the quality of machining. Improper fitting of a job can lead to an accident, breakage or inaccuracy in machining. Also, a magnetic chuck holds the entire material, which offers better grip and ensures proper machining. In the case of any given material, the basic role of work holders remains the same despite different tools being required for machining. However, the time taken between job changes is a critical aspect in the manufacturing process. A magnetic chuck saves time during job changing, thereby increasing production rate and eventually decreasing the cost.

Q Future of magnetic chucks Not many Indian companies manufacture magnetic chucks, which gives manufacturers scope for development and innovation. However, major competition comes with new types of clamping devices entering the market. Today, magnetic clamps are being used in every possible sector, including machining of expensive materials for aerospace, railways, automotive, heavy engineering fabrication and various other sectors of the machining industry. The industry needs to open up to new technologies. Instead of focussing on primary investment and quick return on investments, it needs to focus on quality and precision of machining that new technology offers. debarati.basu@infomedia18.in

INSIGHT & OUTLOOK Industry Views New generation machines and components, which assure high-precision machining, need to be supplemented with equally high quality work holders. However, the cost-conscious industry, for long, has been neglecting this small segment. Satish Sadashivan, MD, SCHUNK Intec India tells Debarati Basu how the right selection of work holders can bring about a revolution in machining. Excerpts.

Q Competency of the industry

Satish Sadashivan, MD, SCHUNK Intec India

We have the technology but the industry should generate the demand 130 MODERN MACHINE TOOLS - December 2011

Innovations in the market happen as per the requirements of the industry. In India, however, the industry is accustomed to using mechanical fixtures and is satisfied using conventional devices. The industry only considers other options when conventional systems cease to provide a solution. Modern machines assure precise machining. But, in this process, the industry cannot afford to select work holders casually as precision machining depends on proper positioning of the component during the machining process. The international scenario, on the other hand, is very different. A thorough investigation into workholding devices is made before making any investment. The Indian industry is gradually marching towards incorporating sensitive workholding devices that match the machining process. For delicate and precise work pieces, the clamping system needs to be sensitive. In such cases, care has to be taken to ensure that clamping devices do not deform the work piece. We have equipment, which sets the clamping positions. The devices are precise. They repeat over a large number of cycles (half a million cycles) within 5 or 10 microns and give reasonably high stroke possibility. Precision is relative to stroke â&#x20AC;&#x201C; smaller the stroke, better the precision.

Q Of workholding equipment

and robotics Manual handling of components cannot match the speed of the production process that the industry has achieved today. In such a scenario, robotics will dominate the shop floor as it will ensure

consistency in quality and reliability. As for subsequent workholdings, loading and unloading of the component during the process will play an important factor. With robotics in place, we can envisage moving fixtures where the robot itself will hold the fixture and move around the spindle required for machining. In this situation, sensory systems will become very important for robotics to ensure proper, timely and quick clamping and declamping of work holders. While robotics will ensure precision machining, work holders also need to provide similar level of precision to complete the equation. The increasing demand from the industry will bring in optimum level of automation by the next decade and high precision work holders too will find their place in the system.

Q Transitions in clamping

device materials Lack of rigid and reliable work holders will give products a bad finish. Hence, it is important to have the right kind of clamping devices for different materials. Specialised industries, like aerospace, have been using materials like titanium and Inconel, which are â&#x20AC;&#x2DC;hard to machineâ&#x20AC;&#x2122; materials. The usage of such materials over the last decade has subsequently brought in a dramatic change in the scenario of workholdings. Earlier, in aerospace machining, the impeller blades of turbines were held by mechanical holders, which did not give the best result on the machined component in terms of finish and tolerances. Today, the industry has come up with innovative work holders like a set of flexible pins that can easily be adjusted as per the shape of the material being machined. Unlike mechanical vices,

Industry Views these are clamped at various points around the component to offer higher strength while machining. The latest trend in this industry today is ice clamping. In this technology, a delicate work piece with infinite symmetry is held into position using the freeze concept. Water is sprayed onto the work piece to be placed on the icing plate. The temperature is controlled with compressed air to the freezing point and the ice formed clamps the work piece. The additional advantage of this technology is the cooling of the machined areas without additional coolant. However, the technology is used in a limited way the world over and has specific application areas. Also, customers usually have issues pertaining to minor machining on the finished product. Clamping finished areas of the component leave clamp marks. For this, we have come up with a solution of using non-metallic workholdings made of fibre reinforced plastic, which do not leave holding marks.

Q Challenges faced On the global platform, the Indian manufacturing scenario is recognised mostly for its cost-competitiveness. As a result, Indian manufacturers adopt severe cost-effective production processes when they have to supply to a competitive international market, which, in turn, deters them from selecting high-end work holders. The international market, however, has already embraced the technology. Convincing Indian manufacturers to look at high-precision work holders in terms of long-term investments rather than cost per component expense is a challenge. We have sufficient technology and are one step ahead of the machining capacity but the industry should generate that demand for high-end clamping technology. The industry needs to think beyond the initial investment and bring in a holistic vision.

Q Scope for workholding segment As a new trend, we have been supplying workholding equipment not only to machines tool builders, but also for

assembly lines and metrology. Here, the same workholding can move the work piece to different stages of the manufacturing process within five microns of accuracy.

Q Dealing with competition It is an open market. There are various categories and every supplier has a market in every segment â&#x20AC;&#x201C; be it low or niche. With technological advancements as well as growing quality consciousness, machine builders today do not want to compromise on quality. An industry that seeks to become globally competitive cannot work with low quality machines. Fortunately, Indian manufacturers have realised this and are upgrading their technology to meet the needs of the future.

Q Next level of clamping devices One can only imagine a totally flexible work holder, which will work on the concept of a jelly and would be able to hold any component and material. debarati.basu@infomedia18.in

INSIGHT & OUTLOOK Titanium Machining

Establishing the right

he advent of the aerospace industry in the country and the fast growing automotive sector has changed the entire equation of how components are machined. The need for lighter components has brought in highly sophisticated materials like titanium, which promises to offer components properties such as lightweight as well as high strength. But this has also compelled the industry to take a leap from the conventional machining processes and revamp every aspect of manufacturing. With highly sensitive and sophisticated material in place, which is to be machined in an expensive machine embedded with the latest technology and high-precision cutting tool, the entire dynamics of machining can go for a toss if the spindle connection for the cutting tool does not match the requirements of the process. Talking about the need for the same, Vivek Maheshwari, GM – Sales, Kennametal India Ltd, says, “Building today’s modern aircraft, many engineers are switching to high-strength lighter alloys like titanium for component materials to increase fuel efficiencies. Machinists are challenged to maximise metal-removal rates to achieve production efficiencies, yet face low cutting speeds and considerably higher cutting forces. Machine tool builders must also provide greater stiffness and damping in their spindles to minimise undesirable vibrations that deteriorate tool life and part quality. When machining tough materials like titanium, cutting speeds are relatively low due to the thermal effects on cutting tools. “In response, machine tool builders have improved stiffness and damping 132 MODERN MACHINE TOOLS - December 2011

on spindles and machine structures over the years. Spindles are being designed with abundant torque at low rotational speeds. Although all these advances add to greater productivity, the spindle connection often remains the weak link in the system,” Maheshwari adds.

Changing equations

The rise in the use of sophisticated materials coupled with high-precision cutting tools for machining garner equal importance for the selection of the right type of spindle connect to ensure optimum quality machining. As Indian manufacturing is stepping up with the global market to be at par with the latest in cutting technology for machining difficult to machine materials like titanium, there is an increased awareness in the industry for proper spindle connect, writes Debarati Basu.

Given its low mass, high strength and excellent resistance to corrosion, titanium has come in as a one-stop solution to various engineering challenges for the new age industry demands. This exotic material has an edge over other conventional materials by being 30 per cent stronger than steel but still being 50 per cent lighter. Similarly, it is 60 per cent heavier than aluminium but twice as strong. The aerospace industry today is the single largest market for titanium products. Titanium applications are most significant in jet engine and airframe components that are subject to temperatures up to 1,100°F. In automotive applications, titanium is used in engine valves, connecting rods, wheel-rim screws, exhaust systems and suspension springs. Engine components made of titanium increases horsepower and torque while improving fuel economy and reducing issues of noise and vibration. In exhaust systems, the use of titanium reduces material weight by approximately 50 per cent as compared to other conventional systems. This automatically increases the product life. Machining of titanium alloys requires cutting forces, which is only slightly higher than those needed to machine steel. But these alloys have metallurgical

INSIGHT & OUTLOOK Titanium Machining characteristics that make them somewhat more difficult to machine than steels of equivalent hardness. Classifying titanium as a difficult to machine material comes with reasons of it being a poor conductor of heat. Most of the heat generated during the operation gets concentrated on the cutting edge and the tool face. This material also has a strong chemical reactivity with materials in the cutting tools at tool operating temperatures causing galling, welding & smearing and rapid destruction of the cutting tool. Titanium also has a low modulus of elasticity, which means that the work piece tends to move away from the cutting tool unless heavy cuts are maintained. Slender parts tend to deflect under tool pressure and cause chatter. Rigidity needs to be maintained in the entire machining process. Hence, the requirement for an appropriate spindle plays a major role in maintaining the rigidity while machining. Emphasising on the need for rigidity, Mukund Bharadwaj, Deputy CEO, Guhring India Pvt Ltd, explains, “For optimum machining, the machine needs to be equipped with an appropriate tool holding mechanism and the spindle should be rigid enough to support the machining process by facilitating the user to set the required speeds and feeds. Additionally, the spindle should be sufficiently rigid to take the cutting forces that get generated while machining titanium when these high parameters are run on the machine.”

Selecting the right connect Elevating the importance of the right kind of spindle has also brought in a transition in the making of spindle. However, various aspects need to be taken into consideration during the selection process. “The tool-spindle interface must withstand high loads and yet maintain its rigidity. In most cases, it determines how much material can be removed on a given operation until the tool deflection is too high or the onset of chatter is reached. High-performance 138 MODERN MACHINE TOOLS - December 2011

machining is commonly characterised by the use of high feeds and aggressive depths of cut. With ongoing advances in cutting tools, there is a need for a spindle connection that makes the best utilisation of available power possible,” says Maheshwari. Several different types of spindle connection have been developed over the last few decades. Due to a good cost benefit position, the 7/24 ISO taper became one of the most popular systems in the market and was used successfully in many applications. But it had its limitations in terms of accuracy and speed. The advent of face contact represented a major step forward over the standard 7/24 taper. The combination of face contact with

While all the advancements made in the machining process add to greater productivity, the spindle connection often remains the weak link in the system. 7/24 solid taper provides higher accuracy in the Z-axis, but also presents some disadvantages, like the loss in stiffness at higher speeds or high side loads. Most of these tools in the market are solid and the spindles have relatively low clamping force. Connection stiffness is limited, as radial interference needs to be kept to a minimum. Required tolerances to achieve consistent face contact are thus very tight, thereby leading to high manufacturing costs. “It is very critical to ensure that the connection from tip of the tool to the spindle is sufficiently rigid i.e., the right kind and right size of adaptors avoiding usage of additional units like extensions or adaptors have to be used. The clamping of the tool in the holder should be rigid enough to enable the forces to be transmitted to the machine spindle and in turn to the machine frame. It is also important to maintain the spindle temperature as the high forces that are generated heat up the

spindle, which could lead to some other machining difficulties,” explains Bharadwaj. While machining tough materials like titanium, cutting speeds are relatively low due to the thermal effects on cutting tools. In response, machine tool builders have improved stiffness and damping on spindles and machine structures over the years. Spindles have been designed with abundant torque at low rotational speeds. “The spindle connection must provide torque and restrained bending capacity compatible with machine-tool specifications and the requirements for higher productivity. It becomes obvious in end-milling applications, where projection lengths are typically greater; the limiting factor is a spindle interface’s bending capacity. The most critical parameters of a taper-face spindle connection are the clamping force and radial interference,” says Maheshwari, adding, “Kennametal’s response to this traditionally weak point has been with the next-generation KM4X. Some systems may be able to transmit considerable amount of torque, but cutting forces also generate bending moments that will exceed the interface’s limits before torque limits are exceeded. The combination of the KM4X system’s high clamping force and interference level lead to a robust connection and extremely high stiffness & bending capacity for greatly improved performance in titanium machining. KM4X overcomes the limitation on the bending capacity present in other connections, which allows maximum available spindle power and torque to be utilised in critical operations like milling of high-strength materials.”

Choosing wisely is the key Manufacturers today have several spindle interface choices when making a machine tool investment. With more materials that are tougher to machine, which requires considerably higher cutting forces, choosing a spindle connection wisely to achieve maximum cuttingedge performance is indispensable in the manufacturing process. debarati.basu@infomedia18.in

More of a

system than a device Machine tools have always been the backbone of manufacturing. They have lent unwavering support to the manufacturing process, which faces the mixed challenges of technological advancements and economies of scale. Workholding has always been an inseparable part of the machining process ever since its inception. Although the basic underlying principles pertaining to workholding are still applicable till date, there is much more than what meets the eye in the backdrop of modern day machining manufacturing. A peek into the mysteries of this complex world.

ust like innumerable human beings work day in and day out to pursue their relentless pursuits in this fastpaced world, there are countless machines that work incessantly to produce implements & devices – the needs of which are indispensable in this complex cyclic evolution process. Similar to their human counterparts, the machining of micron-precise parts from automotives to aerospace, electronics to medical, which churn out in volumes, undergo high levels of

140 MODERN MACHINE TOOLS - December 2011

stress. Yet they have to ensure that they constantly attain their ‘goals’!

Challenges to face As demands in terms of accuracies and features on the produced mechanical parts grow to increasingly tighter specifications, the workholding process, which holds the key to consistent repetitive manufacturing production, faces innumerable challenges. Computerised Numeric Controls (CNC) deployed by the modern

machine tools of today are built to highly precise levels of axis motions. Complex profiles on the parts are being machined on five-axis (and more) machining centres. As the rigidities of the machines are able to withstand higher depths of cut & feed rates with lesser vibrations – which can affect the machined surface finish – similarly, the workholding is expected to perform in rigidity and reliably hold the job or work at precisely predefined coordinate positions. And injection moulds with

complex and multiple cavities with the strictest of manufacturing tolerances take the challenge a step further. This implies that there is a need for a workholding system, which is more than just a mere holding device like a basic vice, or which plays an important role in the precision referencing of a work piece with reference to machine axes. Repeatability of the order of lesser than a couple of microns, as offered by leading workholding system producers, paves the way for ensuring this accurate referencing. This is because the work travels from machine tool to machine tool and from one process to another without incurring the expensive and unproductive resetting times.

Trends witnessed The machining field – applied to mould & die as well as precision parts manufacturing – is undergoing rapid changes with regard to the practicalities of the process. More dependence on

computer software sweeps in, in every nook and corner of the manufacturing process right from CAD design, parts and fixtures, 3D models, CNC programmes for cutting paths (CAM), in-process critical measurement checks, quality inspections on CMMs, links to ERP systems and so on and so forth. Each and every stage needs numerical referencing for alignment of the ‘soft’ programme to the actual ‘hard’ physical part. A workholding system offers the solution to either walk through or babysit the work precisely. This shows promise to the advanced ‘machine shops of the future’. Zero-point tooling systems are setting the standard for the part machining industry. Wastage of setup time in dialing on machine and mallet knocking is fast becoming a primitive technique. Workholding tooling systems are applicable to all production machining processes such as milling, turning, EDM die sinking, wire cut EDM, grinding and so on and so forth.

Automation and robotics The moment we think of ‘machine shops of the future’, within the blink of an eye flashes the visual of a robot working in place of a man carrying out the tedious tasks that go on in a tool room. Automation is certainly a trend that is catching up, not only in the advanced western world where it is fairly established today, but also in third-world developing countries, apart from big names like India and China, where plenty of manpower is available. Automation, in this context, does not merely restrict itself to being defined as a robot performing a physical task like holding, lifting, placing and moving a work piece in place of a man. Instead, in modern day machining, it refers to ‘automation’ of the entire process, including the ‘soft’ steps as computer data transfer, which arrives at the right place, at the right process and at the right time. The intelligence of this automation uses RFID or similar chips on each and every work piece to capture its identity and whereabouts throughout

the entire manufacturing process. This enables online tracking of the multi-machine process for constant consistent control. A good, reliable and precise workholding system lays the necessary foundation or platform for the launch of automation of the machining process. The machining process, basically being a machine-driven task, offers the right situation for an automatable process to remove the infrequent manual interventions, which call for stoppage or downtime or unproductive idle time of the machine.

Future outlook Workholding on machine tools of modern age has undergone a paradigm shift from the conventional work clamping methodology. It will see more of a system-based approach rather than a system merely based on discreet components or devices. As the machine tool industry undergoes technological advancements, workholding will have to follow suit. The rapid and infinite possibilities being ushered in by IT in this globalised world will retain the pace of demands thrust on manufacturing. This promises a future that holds in store a positive outlook for the machining industry. It promises a future where there is light, though somewhere near to the end of the tunnel.

This holds down costs on both larger-volume part runs and short-run jobs programmed to run sequentially. The shop can also achieve tighter tolerances and more easily meet just-in-time delivery targets, among other gains. The bottom line is that the company’s investments have enabled it to take on more complex work from more demanding customers with deeper pockets, says Alan Garey, President, Decimal Engineering.

On the upgradation mode Of course, getting the new equipment to meet its full production potential required the shop to abandon its long reliance on 2 1/2-D CAM, so it upgraded to the multi-axis Edgecam Pro system. However, the Garey brothers emphasise that the software’s benefits go beyond simply providing the capability to program the shop’s new machines. It has essentially taken over many of the repetitive, tedious tasks that previously required significant investments of time and knowledge from the shop’s most valuable resource—its people. As a result, employees can concentrate on bolstering customer relationships, outperforming competitors and winning new business. These benefits begin upfront, where the software saves time for the seven full-time engineers the company now employs to review, design or redesign customer jobs. As part of its transition to providing product development and engineering, the shop has moved to full 3D CAD design and solid modelling by bringing in SolidWorks design software from Dassualt Systèmes and upgrading its Autodesk Mechanical Desktop and AutoCAD systems to Autodesk Inventor. This has improved the shop’s ability to ensure that parts work for the customer upfront, before even a prototype is produced. However, engineering revisions and translation problems would be a significant burden on programmers if the new design systems could not 144 MODERN MACHINE TOOLS - December 2011

effectively integrate with the company’s CAM package. Enter Edgecam’s Solid Machinist module, which provides tight associativity with both of these programs. Mark Garey, Engineering Manager, says Solid Machinist ensures that no data is lost in translation when importing or revising part designs, regardless of the originating system. Additionally, it allows reloading part revisions, which provides a handy way to accommodate engineering changes between repeat jobs—or even within a job—without having to modify the underlying part program. “If we change a part model in Inventor or SolidWorks, the programmer is automatically notified and can download the latest revisions,” he notes.

Alan Garey displays a missile control system part produced on the nine-axis Mori Seiki turning centre in the background

Strategy manager Beyond the engineering stage, Edgecam enables the shop to simultaneously standardise and automate part programming. This is done in large part through the software’s Strategy Manager, a visual, flowchart-oriented approach to manage the programming of repetitive machining operations. For example, Decimal machines holes in practically every part. Although there are countless ways to machine a hole of a given depth and diameter, the company can typically identify one particularly effective method. Strategy Manager captures and stores such standard procedures as routines and subroutines that can be called up as-needed for any given job, the programmer explains. “Almost as soon as we got started, we found that Strategy Manager reduces programming input effort in making holes by as much as 80 per cent,” he says. Strategy Manager’s effectiveness relies on input from other software features. For example, the strategy for any given machined feature involves a particular combination of tools, machining sequences, specifications and tolerances, all of which are managed by the software’s tool store module. Similarly, the CAM system’s feature finder ensures that programmers will not miss a given feature, no matter how complex the geometry. Another time-saving software feature

for Decimal is Edgecam’s builtin graphic simulation capability. Simulation presents programmers with precise digital representations of manufacturing operations, complete with the appropriate cutting tools, workholding, tool paths, operation sequences and other facets of the process. By ensuring that parts are machined as the shop intends, this capability virtually eliminates wasteful trial runs and time-consuming program tweaks on the shop floor. Machine tool utilisation and profit margins have increased significantly, due in no small part to Edgecam’s contributions to the new 3D culture on the shop floor as well as the standardisation and automation of processes. Moreover, the shop has realised its goal of producing its own custom products and providing customers with engineering services.

Figuring out where the business is headed is fundamental to strategic planning, and charting out growth plans has become mandatory for all organisations. The Indian machine tool manufacturers too need to concentrate on various business aspects to compete with global players and meet the growing demands in the country. By Nishant Kashyap

ndian machine tool industry is witnessing considerable growth in terms of local demand, which is also grabbing the attention of global players, who are setting up their facilities in the country to strengthen their presence here. In addition, industries such as, automotive, aerospace, energy, infrastructure and steel – the customers of machine tools industry – are booming in a big way, thereby opening up new avenues for Indian machine tool builders. All these point towards the significance of making the right business plan to tap the potential to the fullest.

customers successfully. Extensive R&D provides competitive advantage and also facilitates entry into new markets, besides increasing revenue generation. It enhances brand value and enables the company to pave the path towards innovation. But the industry has a long way to go in this regard. As India has become the global manufacturing hub, machine tool manufacturers need to invest more in R&D to offer best technology to its customers and keep pace with the growing demand. The investment in this field would determine Indian machine tool manufacturers’ competitiveness vis-àvis the developed countries.

Focus on R&D In recent times, R&D has become the pillar of success. Providing the best technology and sophisticated machines has become the need of the hour for all industries, machine tool sector not being an exception. Indian machine tool manufacturers have also realised the importance of investing in R&D to meet the changing requirements of

Technical collaboration The Indian machine tool companies should enter into technical collaboration with global leaders in the arena, so that machines of international standards are available in the country at lower and competitive prices. Companies can remain in the forefront of supplying leading technology to the end-user by

collaborating with industry leaders in software development and machine design areas. The collaboration can also include activities like production, planning and the development of machines, as well as sales and services. Moreover, such collaboration will be helpful for exploring the opportunities worldwide, facilitating technological advancements, and gaining a competitive edge.

Skill development Human capital is one of the most vital assets in any organisation on account of its efficient functioning. As a result, companies are increasingly focussing on training and developing to attain competitive advantage and drive their value. Incorporating training and development processes into metal working industry is significantly associated with immediate operational benefits. The introduction of new technologies has reduced the demand for unskilled labour and raised the importance of advanced skills and competencies in the December 2011 - MODERN MACHINE TOOLS 149

Strategy: In-depth Analysis industrialised economies, which clearly indicates that skill development should be viewed as a lifetime endeavour. Most companies often do not pay much heed to this aspect and hiring is done in an unprepared manner without much planning. It is important that each employee meets the expectation of the company for achieving its long-term and short-term objectives. The die & mould industry calls for highly skilled manpower; Indian companies need to select the right candidate to deliver the right technology.

After sales services With growing competition the world over, after sales service has become the key business strategy. The clients emphasise on quality consistency of products and services from any brand. The consumersâ&#x20AC;&#x2122; confidence can be gained by ensuring that they get the same or better quality every time. Consistency makes it easy for customers to choose the service, and results in repeat orders, thereby bringing in customer loyalty. A loyal client base and customer support cannot be created with discrepancies, but with dependability and consistency. After sales service helps in keeping the customers satisfied. Customer service enables proper communication of their needs to the product or service provider. Focussing more on after sales service will help machine tool companies know what their customers want and expect from them. Thus, they can offer customers desired products that will satisfy their needs.

Environment-friendly solutions Growing concerns towards environment are pressurising companies to adopt green technology. Nowadays, customers are demanding environment-friendly machines that reduce wastage and have a direct impact on overall revenue. It takes a lot of valuable energy and materials to manufacture products, and the resulting industrial waste can be difficult to manage. Reducing and recycling waste becomes imperative here, as it can bring in huge savings in terms of money and 150 MODERN MACHINE TOOLS - December 2011

resources. An audit can identify simple ways to easily reuse waste without extensive capital investment.

Rigorous marketing Marketing is perhaps the most important aspect of any business, beyond product, distribution, pricing or location. A companyâ&#x20AC;&#x2122;s brand forms its identity in the world. Marketing defines precisely how a customer perceives the brand now, and its future prospects. It makes a huge difference, as it has the power to impact all decisions big and small, of the customers. The machine tool manufacturers need different type of marketing efforts to focus on potential customers and increase the brand visibility in the industry.

Effective waste management system Waste and energy is a significant part of operating costs in industries as it directly affects the overall revenue of an organisation. Waste management refers to managing the effective use of waste and other industrial affiliates. It takes a lot of valuable energy and materials to create and manufacture products and the resulting industrial waste can be difficult to manage. Reducing and recycling waste becomes imperative. Capturing and recycling waste during the manufacturing process can save money. An audit can identify very simple ways to easily capture and reuse waste without extensive capital investment. Through better waste management, companies can even enhance their public image by understanding the impact of their use of the precious resource on the community at large. In this rapidly growing manufacturing world, waste management has become a key strategy to save cost and increase efficiency. Most of the manufacturers have realised that to be competitive, they must have effective waste management system.

Adopting lean manufacturing Initially, lean manufacturing was implemented in automobile industry only, but its phenomenonal success made other industries like metalworking

to implement the same. Indian machine tool industry has also shown their interest in lean manufacturing. The industry manufactures almost complete range of metal-cutting and metalforming machine tools. The industry is booming with high growth in the domestic as well in the export market. Till date, all the growth has been possible because of foreign machine tool manufacturers and their valuable experience. Being an import driven industry, Indian machine tool manufacturers are trying hard to become a complete solution provider and manufacture sophisticated machines to compete with global giant. To achieve this, many Indian companies are adopting lean manufacturing and Six Sigma process. The Indian metal working industry is relatively labour intensive by global standards and is in transition stage with low cost base for exporting labour intensive products. In coming years, to be competitive, the Indian machine tool builders need to adopt lean manufacturing and other quality standard techniques in their system.

Constant upgradation Innovation has become the stepping stone to success in the present times. Only those who continuously upgrade their technology will survive in the industry. In the contemporary market, customers have more choices than ever before, which pave the way for machine tool builders to continuously evolve in its design and development of products. The research spending as a percentage of sales among Indian firms are low when compared to that of companies in developed nations. Today, business environment has become dynamic with more demanding customers and fierce market competition. Many Indian firms have increased their R&D expenditure and are coming up with sophisticated solutions. To stay ahead in the competitive race, Indian machine tool manufacturers will have to embrace innovation as the key strategy for development. nishant.kashyap@infomedia18.in

Tips & Tricks: Preventive Techniques

TIPS

for reducing work hardening during machining High temperature-resistant alloys can be difficult to machine as they generate high cutting forces during the process, leading to high pressure and heat, which in turn results in work hardening. By Swapnil Pillai

Always keep cutting tools sharp.

The machine tools and the workpiece must be firmly held to prevent vibration and chatter.

3 4

The process should be run at the recommended feeds and speeds for the material being machined. If these are incorrect, tool rubbing will increase heat.

Good lubricants should be used, especially for heavy cuts at relatively slow speeds. Thinning with paraffin is recommended for higher speed finishing cuts to keep the workpiece and tools as cool as possible.

While drilling, it is recommended to run at constant feed whenever possible.

7 Work hardening of materials is a condition that should be avoided while machining. It occurs when a metal is strained beyond the yield point. The increasing stress further deforms the metal, which becomes stronger and more difficult to machine. Stainless steel and high-temperature alloys are prone to this phenomenon. Mentioned here are some of the techniques to avoid work hardening during machining.

8 9 10

152 MODERN MACHINE TOOLS - December 2011

Use rigid set-ups between tool and workpiece to counter workpiece flexure.

During tap breakage, the cause may not be the tap, but a work-hardened hole.

The depth of cut must be such as to prevent the tool from riding in the workpiece.

Use proper tool maintenance as it helps reduce work hardening problems.

Interrupted cutting must be avoided wherever possible as a greater degree of work hardening occurs as the tool enters the workpiece.

Reality Check: CNC Machine Myth 1: Anybody can run a CNC machine

Decoding

CNC myths & misconceptions

Often, managers working in companies that use Computer Numeric Controls (CNCs) might have started their careers in other areas. While this is not necessarily a drawback, managers with limited shop experience cannot always understand what is actually going on in the shop. Here are five frustration-causing miscues that have been noticed among management and shop employees.

154 MODERN MACHINE TOOLS - December 2011

Fact: While there are applications that have been engineered in order to enable a person with minimal training to operate a CNC machine, these applications are few and far between. The reality is that a CNC operator must perform several tasks that require knowledge and skill. Common operator tasks include workpiece loading and unloading, cycle activation, cycle monitoring, workpiece measurement, acceptability evaluation, statistical process control reporting, sizing (offset) adjustments, and dulltool recognition and replacement. The more operators are expected to do, the more they must know â&#x20AC;&#x201C; and more training must be provided.

Myth 2: If a job has been run before, it will run without problems in the future Fact: When a set-up person is having problems with a job, it is not unusual to hear a manager say something like â&#x20AC;&#x2DC;I thought we had run that job before.â&#x20AC;&#x2122; The assumption is that just because the job has run in the past, it will run flawlessly in the future too. However, any difference between the way the job was run in the past and the way it currently is running could potentially cause a problem. Variations must be eliminated in order for jobs to run consistently without problems.

Myth 3: Once a new job is running, you should be able to predict when a production run will be completed Fact: With hot jobs, it is tempting for managers to start predicting when the machine will finish a production run. After all, managers are in contact with demanding customers. May be the machine has a five-minute cycle time and it takes 30 seconds to unload and load. With 200 parts to run, the job should be completed in about 18 hours theoretically, but other factors determine how long it will actually take to complete a production run. How long will cutting tools last? How long will it take to replace dull tools? Can the operator keep up with the machine? With repeating jobs, managers should be able to make this prediction. However, accurately predicting when a new job will be completed may be impossible.

Reality Check: CNC Machine Myth 4: G-code programming is a thing of the past

Myth 5: CAM system programmers do not need a machine shop background

Fact: Many managers believe that all CNC

Fact: New programmers seem to have one of two backgrounds: shop experience or computer experience. Admittedly, CAM systems do simplify the task of developing programs – a person with limited shop experience can easily get through the creation of a CNC program. However, programmers with limited shop experience tend to take what they are given while those with extensive shop experience will make the CAM system give them what they want.To create the most efficient CNC programs, a programmer must know about processing, machining operations, cutting tools, cutting conditions and how set-ups are made. They must also be able to direct the set-up people and operators, who use the programs, they create. Again, a CNC programmer must possess a good understanding of basic machining practices to win the respect and confidence of experienced shop personnel.

programming is done using the company’s CAM system. But they must remember that the output from any CAM system is G-code – the same kind of G-code that manual programmers write out longhand. Of course, it is the G-code program that the CNC machine actually runs. If a set-up person has a problem that requires a program to be changed, it is often quicker and easier to change the G-code at the machine than to have the programmer make the changes in the CAM system, recreate the G-code program and send it back to the machine. Changing programs at the machine requires an understanding of G-code programming. There are other reasons why CNC people should understand G-code programming. If a programmer is to judge the quality and efficiency of G-code programs generated by a CAM system or modify the way G-code is created, he or she must understand G-code. If some jobs are simple, it is often quicker to manually correct the program than to use a CAM system.

Chennai Dec. 8-11, 2011. Chennai Trade Centre, Nandambakkam

Enthralling engineering enterprises Tamil Nadu continues to be a favoured destination for investments not only for the service sector but also the manufacturing industry due to several factors like the availability of abundant talent pool and the infrastructure facilities including sea, air, rail and road network. Catalysing growth to the next level is the fourth edition of Engineering Expo Chennai, scheduled to be held from December 8-11, 2011. This edition will further augment the industrial activities that are synonymous to the competitive spirit of Engineering Expo and the state as well. By Bhargav T S apan has identified Tamil Nadu as one of the most potential states for investments recently, and towards this, the Japanese Ministry of Economy, Trade and Industry (METI) has signed a bilateral economic co-operation agreement with Tamil Nadu. The agreement is a feather in the cap for the state as it has been identified as a potential investment destination by none other than an industrially advanced country like Japan. It is estimated that about 240 of the 725 Japanese companies are already in Tamil Nadu and many more investors are looking at the state as an attractive investment destination. According to a senior State Government official, the joint Steering Committee of METI and the State Government have identified several infrastructure projects in the state. He added that the government has plans for establishing a Japanese industrial cluster near Chennai.

Fostering development Acting as a key enabler in propelling the growth of the manufacturing and service sectors in the state is Engineering Expo Chennai organised by Infomedia 18. The fourth edition of the Expo to be held in Chennai will be a conducive platform in amalgamating the capabilities of the state with the specific needs of the industries. “The paradigm of Engineering Expo participation has grown beyond

175+ exhibitors 12,000+ expected visitors ` 45 crore worth business expected 44,000 sq ft exhibition area 5,000+ products to be showcased 26 cities to participate expectations and become the hub for all engineering activities like manufacturing, designing, construction and EPC projects,” states Abhishek Goyal, Marketing Executive - Transformer Division, Electrotherm India. Countries like Korea, Japan and Thailand have evinced interest in investing in the state particularly close to the major ports. Tamil Nadu has a unique distinction of having three major ports – Chennai, Tuticorin and Ennore. It also boasts of having the first corporatised port – Ennore, in the country. “Opportunities are abundant in the areas of power, including renewable energy; roads and minor ports development; water augmentation; wastewater treatment; logistics and industrial parks,” asserts

M Velmurugan, Executive Vice Chairman, Guidance Bureau, Industries Department, Government of Tamil Nadu. The State Government is facilitating investments through exclusive industrial estates for industries from these countries. With Chennai emerging as the hub of international investments, the government is concentrating on improving the urban infrastructure. According to the industrial development authorities, the government will launch two special programmes – Chennai City Development Mission that will include the suburban areas with an allocation of ` 500 crore; and an Integrated Urban Development Mission for other cities and towns at an investment of ` 750 crore. A separate project for the industrial development of the southern districts is also in the pipeline involving creation of a self-sustainable industrial growth corridor on the MaduraiTuticorin highway. A detailed project has been prepared with locations identified for creating clusters of investment regions for manufacturing, agricultural business, knowledge hubs and tourism. These projects

Event Preview will be implemented through publicprivate partnership, the government sources reveal.

Growth catalyst The State Government, apart from large industries, is also looking at accelerating the growth of Micro, Small and Medium Enterprises (MSMEs) with additional incentives. The first step will be a three per cent interest rebate on loans provided by the Tamil Nadu Industrial Investment Corporation. Tamil Nadu Small Industries Development Corporation has identified over 2,256 acres in 25 locations to promote industrial clusters for MSMEs. The government is also revamping land pricing policies to simplify the processes. According to Goyal, since 2009, Tamil Nadu has become the major hub for most of the manufacturing industries. “The Engineering Expo has become an ideal place for companies in various manufacturing sectors to showcase their product strength. It extends its purpose to both buyers and sellers of engineering products. On one side where the sellers can cater to a large potential client group, even the buyers are made aware of the latest technological changes, which in turn help them choose the best product. Secondly, considering the level of competition in cities like Chennai where most of the companies have entered a price war, platforms like Engineering Expo are the best way to invest in marketing and reach out to a larger clientele,” he adds. Sandeep Khosla, CEO – Publishing, Infomedia 18, states, “The last three editions of Engineering Expo have contributed immensely to the engineering and service industries from this part of the country. Besides, it has significantly benefited the small and medium enterprises in spreading their wings, as the event provided an ideal platform to connect the buyer and the seller. As we look forward with further value-additions
