Editorial

Times are changing escue plans running into hundreds of billion dollars to prevent sovereign debt crisis, volatile energy costs and rising demand for financial inclusion among several strata of society across the globe, irrespective of the stage of a particular country’s economic prosperity. Are these mega challenges confronting the world today not highly unprecedented and almost unthinkable just a few years ago? The idea here is not to sound like a doomsday prophet, but to recognise the reality of a fast-changing global phenomenon and more importantly, mitigate the risks effectively.

Change is not something new for an organisation of any size or industry. In fact, progressive ones make that significant difference by managing change in a sustainable manner. A few months ago, we also embarked on a similar journey to ‘change’ ourselves, more precisely our brands, for better. In this exciting and challenging soul searching sojourn, we revisited & thoroughly analysed every practical aspect of our motto of providing informative empowerment to our audience and not merely publishing content. Although we have put our best efforts in perfecting the product and practices further, we would also submit that the best practices for managing change are still elusive. The result, as you can see, is the new avatar of ‘MODERN MACHINE TOOLS’. From the brand new sections to focussed features, emphasis has been given on ensuring more analytical, in-depth and contemporary first-hand information. Of course, all these are presented in a lucid and elegant way, thanks to an optimum combination of applying mind over matter as well as some of the latest publishing software available. Rather than blowing our own trumpet, we will prefer your valuable feedback on these changes. Suffice to say, it will help us in our ongoing endeavour to help our audience in terms of receiving superior value on a sustained basis. Happy reading!

Inflation rate worries Indian manufacturers The continuously rising inflation and interest rates has got the Confederation of Indian Industry (CII) concerned about the growth outlook for the country which is deteriorating rapidly. Experts feel that a GDP growth of

8.0 per cent may not be achievable not only in the current year but also in the forthcoming year. This invariably impacts the machine tool manufacturing industry. With the growing global competition and opportunities in offer, this could have been the best year for the Indian manufacturing industry to make a headway towards progress. While the dependence on imports is still at its peak, it will be more difficult for the industry to penetrate into the global competition with the increase in the raw material prices, fuel prices etc. “At a time when economic policy should focus on the creation of jobs, it is unfortunate that the economy is being forced into a sluggish growth phase”, said B Muthuraman, President, CII.

Technology & Innovation Material provides stability and strength HASCO, a mould-making company, recommends TOOLOX33 to its clients as a better alternative to the conventional materials 1.2311 and 1.2312 as it is a fully-hardened and tempered tool steel with a hardness of 29 HRC. Its

unique structure is significantly better than that of established DIN steels and comparable specialised steels. ESU properties ensure excellent polishing, etching and graining results for high-quality surfaces. Due to its low carbon content, this stress-relieved material is excellent for welding. Its low tendency to distort at a wide range of machining volumes as well as its high form stability enables the tightest possible machining tolerances. There is no need for expensive and timeconsuming stress-relief annealing and re-machining such as costly grinding work. Finishing can therefore be carried out with just one clamping process. TOOLOX33 is available as a standard plate in the proven HASCO qualities and tolerances P1100 and K20; special dimensions can be supplied on request at short notice. This new TOOLOX33 provide metallurgical benefits in the standardised HASCO plate sizes, which represent great value for money.

Consumables with better life and performances Hypertherm, a US based manufacturer of advanced metal cutting systems, is now selling consumables for Kaliburn Spirit plasma cutting systems that last at least twice as long as the OEM consumables. Testing shows the life expectancy of the consumables increases by two to three times when cutting at 275 amps and below, and increases more than 50 per cent when cutting at 400 amps. In addition to lasting longer, the consumables deliver better and more consistent cut quality, resulting in the need for less secondary work. This

technology has resulted in life and performance improvements. SilverLine electrodes contain a solid silver front so they wear more slowly; CoolFlow nozzles have an angled o-ring, deep cooling contours and thicker walls to extend the working life; and the swirl ring is made with lava instead of ceramic, making it more robust and economical. These new Centricut consumables for Kaliburn reduce the overall cost of operation and deliver exceptional cut quality and process reliability. At the same time, they maintain the fast cutting speeds. The Centricut brand consumables are available for all Kaliburn Spirit and ProLine systems. These products are precision manufactured to tight tolerances so customers get consistent, reliable performance from their cutting system.

IN CONVERSATION WITH Stephen Nell

China will win the sprint but India will win the marathon …asserts Stephan Nell, Managing Director, Körber Schleifring GmbH. With the global stock market oscillating between ambiguous and mystifying numbers, Nell discusses how Asia is being seen as a haven of stability with the markets fluctuating. Talking to Debarati Basu, he magnifies on the promises of the rapidly growing Indian economy. Q Amid rapid technological

Q On the heels of a recent

advancements, tell us how this industry is coping up with the growing global demand?

Greece bailout, in which direction do you see the markets in Europe and rest of the world moving?

In Asia, specially in India, the market is taking big steps forward. If we look at it from a technology point of view, the developments in the emerging markets of India and China are moving in the same direction as that of Europe the US. The products that we have are ready to fulfill the needs of the customers. We have premium products and the customers are ready to pay, not just because we are a Swiss and a German company, but because of the performance of our machines.

As far as the future of the industry is concerned, we are looking into a crystal ball. We do not really know what the future holds for us. Over the last few weeks, the stock markets have not shown a healthy sign. Today, there are two theories that we are counting on. Some say that this time the crisis will not affect the economy while others forecast that the market will see a downsizing over the next two years. If we were asked this question three months back, then we were sure to see a growth over the next two to three years, with the market

MODERN MACHINE TOOLS - November 2011

reaching its peak by the year 2014. But now the situation has changed. However, globally the market paints a totally different picture. There is a possibility that the US might step into a second recession. Asia cannot be counted with Europe or the US with China growing rapidly. We are quite optimistic about Asia, but very conscious about the developments in the US and Europe. However, we do not believe that we will see another crisis soon.

Q The US economy has also seen

a downturn recently. What are the precautionary measures that you have taken this time? I don’t think this crisis would pose a big problem for us this time but it would

Stephen Nell certainly be difficult for many companies whose survival will be tested again. The last crisis was a hard one. The market did not have the time to adjust to the negative impact of the credit crunch as it all happened in just a few monthsâ&#x20AC;&#x2122; time. Most companies were just on the verge of getting back on track after the last recession when the news of another recession has hit the market again. If we step into a crisis like that of 2009 in the next 12 month, it is going to be very difficult for many companies to recover. For us, the situation is different as ours is a group which caters to various sections of the industry. Therefore, if we face a normal crisis, the impact on us as a group would not be direct. The impact is more cyclical in nature. Walter is usually the first company to go down as it is close to production, and that impact reaches Studer almost six months later, followed by MĂ¤gerle in the same periodicity. This is the same trend that we observe when the market goes up. For us, the risk is spread out. Also, as a group we are strong in Asia with our operations in China and India. And during normal recessions, these two markets do not drop like the US and European markets. At this moment, we are taking more than 40 per cent of the orders from Asia. So, if Asia stays strong, it would not be a big problem for us.

Q From starting your career

with Fritz Studer AG as a Sales Director to being the Managing Director of the organisation, how has been your journey and in what ways have you seen this company grow? When I started, Studer had an order intake of a little more than 100 million. Four years later, we celebrated an all time high, with more than 250 million. But this was not the success of one single person. It was the success of a team, including all divisions of Studer. The key for success is motivated team. Over the years at Studer, I have been fortunate to be a part of such a team.

Q Being a part of this company

for almost a decade, what has been the toughest decision that you have taken for the company which the organisation looks up to as a milestone decision? I cannot pinpoint or highlight one decision. The toughest time we had was in the year 2009. In this year, we had to take many decisions to overcome the downturn. Looking back, 2009 was tougher than the previous years. I am more proud of the results we achieved in 2009 than those we recorded in 2008, which was a record year in itself. We did not lose money and we could retain all our employees. But once again, it was a team success. Everyone at Studer was fighting the crisis and pitched in.

Q As the Managing Director,

what are the qualities that you try to pass on to every employee to help the organisation to grow? As the head of a team, your first responsibility is the people you are in-charge of. For sure, professional skills are important. But with a highly motivated team, you will reach more than 100 per cent.

Q India is an important part of

your companyâ&#x20AC;&#x2122;s operations. How do you foresee the growth of the Indian market in the next five years? Someone had told me once that China will win the sprint but India will win the marathon. The growth and development in India is not as fast as China but it is growing and is making a steady progress. Over the next five years, although we are not expecting the same growth rate in India as we saw in China, I personally believe in India and in Asia. It is one of the most important markets for us.

Q What is the next trend in the

grinding sector that you feel will make a difference to the industry and how is your organisation

bracing for the next level of competition? There are certain technology jumps that the industry is seeing. But if you look at grinding, it varies a little from technology to technology. So, in cylindrical grinding, the biggest invention was the combination of hard turning with a grinding machine. This machine has been able to reduce production time by 70 per cent. We are also working on new technology in tool grinders, with new design and software, which will prove to be revolutionary development for the industry. We are working on projects with various universities to find the next technology jump in the industry.

Q What are the differences in

reaching out to the Indian market as compared to the European or American market? It is not about European, Indian or a Chinese customer. Customers are different everywhere and our aim has to be to fulfill their expectations. We have to be more patient with our Indian customers because working here is different due to high customer expectations and huge amount of paper work involved in the process. It is much easier to sell a machine in the US than in India. That is the reason why we have set up a separate sales and service unit in India so as to understand customer needs better. However, with the industry growing rapidly, the demand for high-end technology remains the same in India similar to that in any part of the world. But there are also certain challenges that we face here. In India, there is a huge market for cheaper machines, which is not a part of our product line. Also, the level of automation is very low in the country. We had faced the same situation in China initially.

Q What is your message for

budding entrepreneurs? It does not matter what you do, you have to do it just a little better than the others. November 2011 - MODERN MACHINE TOOLS

IN CONVERSATION WITH Bertrand Sicot

There has been a shift by many mould and tool makers towards offering expanded capabilities …affirms Bertrand Sicot, CEO, Dassault Systèmes SolidWorks Corp. Since joining as the company’s ‘second employee’ in Europe, he has steered the organisation towards continued market leadership by ensuring that its software helps create products better, faster and cheaper. Manas R Bastia caught up with him on his recent trip to India to unveil the company’s latest comprehensive 3D design solution suite SolidWorks 2012. Excerpts of the exclusive conversation…

Q How has industrial design

for metalworking evolved in recent years? We have seen significant transition by the CAM vendors towards complete and seamless integration with SolidWorks. This allows industrial designers and CAM programmers to actually use the same tool, SolidWorks, without needing to export/import and repair data. 60

MODERN MACHINE TOOLS - November 2011

From a CAD viewpoint, SolidWorks focuses a lot on surfacing capabilities and complex geometry creation. This allows the creation of any geometry, no matter how complex and enables finetuning of moulds and tooling needed to manufacture these complex shapes. From a business aspect, there has been a shift by many mould and tool makers towards offering expanded

capabilities, such as product design. Since many industrial designers rely heavily on advice from their tool makers, they have begun offering full range design services including CAD, rapid prototyping and even Finite Element Analysis (FEA) and simulation. Finally, the seamless integration that SolidWorks provides between product design, tool design, FEA and

Bertrand Sicot simulation, and now CAM, offers product designers and manufacturers a one-stop-shop ‘design through manufacturing’ environment without compromising on best in class CAD & CAM features and capabilities.

Q How is DS SolidWorks

addressing its customers’ concerns vis-à-vis the latest trends in their respective customers’ business? SolidWorks is committed to offer a full range of tools to help in several areas of manufacturing driven by the need to reduce time and cost. This is demonstrated though our continued efforts with our CAM partners to develop applications that are seamlessly integrated with SolidWorks. We have significantly improved the critical tools necessary to speed up production with improvements in areas like import and repair, including automatic feature recognition and conversion of sheet metal parts, faster and easier mould splitting, etc. In addition, SolidWorks has been leading the industry with Design for Manufacturing (DFM) and Design for Cost (DFC) capabilities with DFMXpress and new SolidWorks costing capability, respectively.

Q How does DS SolidWorks

help in making better design decisions in the product development process? SolidWorks 2012 enables designers to automatically generate real-time manufacturing cost estimates for sheet metal and machined parts as the parts get designed. This saves time for designers as the costs are calculated automatically every time the design changes and they do not need to spend time securing quotes. The costing tool also allows managers and executives to track manufacturing costs during the design phase. This allows designers to go back and make changes based on manufacturing cost so that targets can be achieved consistently. In addition, manufacturers can use the costing tool to automate their

quotation process and precisely meet their profit margins. Likewise, DFMXpress helps designers evaluate if their designs are difficult or even impossible to manufacture. And when it comes to changing materials or manufacturing processes to save costs, SolidWorks provides complete FEA and simulation capabilities to make sure the design will function as required and be reliable.

that have inspired you here to grow? I have enjoyed every bit of my journey with DS SolidWorks, starting as a Territory Sales Manager to becoming the CEO of the company. I am like the man next door. Although my team is there to help me out, I am self-sufficient. Passion, a positive attitude and listening to what I feel is right have given me that extra edge to come this far.

Q How do you deal with a Q In India, a high proportion of

the manufacturing industry belongs to the SMEs. What are your value propositions for this segment? We are focused on improving our customers’ productivity by creating tools that reduce time, cost and improve the quality of products. Most of our 1.5 million customers fall in the SME segment with 1-5 seats of our software. Our products enable SME customers to be more productive, without the high implementation pains and costs associated with traditional product development tools.

Q How do you ascertain an

industry trend? There are many ways we ascertain industry trends including the following: Sales trends (customers’ demands and a watch on competitors) Industry marketing sources (blogs, news, magazines, analyses, etc) Internal marketing gap analysis (where we can add value in the product development process) However, our most reliable and valuable source is from direct contact with our customers. Through enhancement requests, blogs and thousands of on-site customer visits, we collect, categorise and analyse the real needs of our customers and then try to develop their needs into solutions.

Q How do you reflect on

your career growth at DS SolidWorks? What are the three most important aspects

tough situation? What is the toughest business decision you have ever made? As they say when the going gets tough, the tough gets going. I take a deep breath and think about the pros and cons to make the right decision. I believe one has to make decisions with a cool mind. The toughest business decision I had to make in relation to the India market was moving away from Tier 2 channel structure to Tier 1. This decision was tough as the Tier 2 partners had financial information and business would have been disturbed. However, we decided to move to Tier 1 because the customers would benefit and we would be closer to the customers. The process would also make the direct Value-Added Resellers (VARs) more profitable and allow them to invest back into the business.

Q What are your future plans

for expansion, and in particular for India? The future plans of DS SolidWorks are to double our business by increasing penetration in the domestic market and increase our VAR network from 28 to 38.

Q What is your message for

budding entrepreneurs? Never give up! This is the key to success. If you believe you are doing the right thing, just go for it. Nothing is stronger than your inner will. One should have a clear focus and do the right thing for one’s business. November 2011 - MODERN MACHINE TOOLS

The industry today believes in power-packed solutions which are smaller, lighter and laden with intricate accuracies. For this demand to generate compact solutions, size has become the most important criterion in the manufacturing fraternity. With this rising demand, machining, too, has undergone a complete shift where manufacturers are now bound to think at a micro level. Debarati Basu

he industry, as a whole, is undergoing a revolution. Miniaturisation is the trend and manufacturers across the world are trying to incorporate high precision micromachining to reach the next level of accuracy and precision, which can take the industry to new heights. And to achieve this result, micromachining is the solution that the industry is trying to adopt. Micromachining forms the basis of fabrication of micro-components of size which ranges from 1 to 500 micrometres. The need for miniaturisation of devices in a gamut of industries, has led to ultra-precision manufacturing and micro-fabrication. But, many feel that 64

MODERN MACHINE TOOLS - November 2011

this is still not enough. Experts across the globe are now trying to surpass this range to achieve nano level of accuracy. “As a technology, micromachining has advanced a lot in the world. Today, the world is talking at the submicron level of machining. We have ventured into nano-machining and this technology has a long way to go,” says PJ Mohanram, Senior AdvisorTechnology, Indian Machine Tool Manufacturers’ Association (IMTMA).

Technology leap Micromachining as a technology is being widely adopted in manufacturing of various applications that demand micro components. The technology, given the demand, is also being tried and tested

for measures which can break through the conventional machining range. This technology was first used for machine components like semiconductor chips. Now, it has widened its horizon to include a range of industries in its gamut. Sectors like aerospace, defence applications, medical implant and equipment are in a rush to reach the next level of miniaturisation. Micro-machined components play a crucial role for practical advancements in Micro-Electromechanical Systems (MEMS), micro-electronics and nanotechnology. The technology is used for fabricating micro-channels and micro-grooves in micro-fluidics applications, micro-filters, drug delivery systems, micro-needles and micro-

Micromachining probes in biotechnology applications. With the technological leap that the industry is observing today, manufacturers are trying to achieve the level of accuracy that conventional machining could not reach. The race to fabricate the smallest possible component has lead to the realisation of sizes below 10 micron. The advancements in the technology has also recognised industrial requirement at 100s of micron. While for years, machine tool manufacturers struggled to machine difficult machine materials, micromachining has successfully overcome that hurdle. This technology is being intensely used in some of the finer applications of aerospace, space technology and medical implants, which invariably depend on the usage of exotic materials. However, the challenge of achieving greater accuracy, precision and resolution still continues.

Going beyond conventional The increasing awareness about the advantages of manufacturing microcomponents is giving rise to new ways of machining micro components. The technology of micro machining is in itself taking the next leap to redefine precision. The need to create moving parts on a miniature device has opened up applications for sensing devices and devices that physically exert force to create motion. These devices are categorised as sensors and microactuators and are required in every possible micro machined devices. Sensors dominate micro machined applications in the sectors like space craft, air craft manufacturing and even in the automotive sector where the primary application of these devices include speed sensors, accelerometers and sensors to monitor temperature and pressure of the machine. Sensor monitoring of medical implants is also the next most crucial need of the medical industry. Taking precision to the unimaginable heights, the industry today is talking not just in terms of water jet machining, but is also imbibing machining through laser, plasma, electron and ion beams. 70

MODERN MACHINE TOOLS - November 2011

Water jet machining has grown and become highly automated with CAD/ CAM software that control and operate hardware for precision machining. Moreover, Abrasive-Water Jets (AWJs) are capable of machining most materials up to the thickness of about 0.2 μm. Current water jet technology is capable of machining fine features of around 150 micron. The main challenge, however, is to understand and control the supersonic and three-phase microfluidic flow that involves fluid to fluid, fluid to solid, and solid to solid interactions through the nozzle and in the rapidly evolving blind hole. Water jet machining is widely used in medical technology to machine titanium implants, tool-blanks, prefabricated mounting plates, rubber mountings and instruments. Other industries include watch making, electronics like chip support, sensors, printed circuit boards, complex chip sets and jewellery making as well. Laser micromachining today is a mature technology which is widely being used for high precision micro-fabrication. Machining up to 1 micron wide and 2 mm deep can be achieved with laser technology. Scientists across the world are exploring this area of machining so as to have even more stringent accuracy of machining which can go beyond 1 micron. This technology is widely used in some of the areas like aerospace and medical technology where high level of precision and accuracy is required. Laser technology comes in as a viable option to machine a range of materials including metal like aluminium, tungsten, titanium, ceramics, hard to machine materials like diamond, silicon nitride, tungsten carbide, plastics and glasses and crystalline materials. These technologies however are yet to establish themselves in the Indian manufacturing industry. “Although India still does not have the acumen to adopt these technologies, the country has an edge over others for being a preferred destination for business. Many foreign companies have realised that the growth is in Asia. And the best way to enter

the market is through collaborations with Indian companies. This is the time when the Indian industry can make the most of the global technology, which is at its disposal. The industry, government and scientific institutions should work together to grow,” said Professor S Mohan, Visiting faculty at Centre for Nano Science and Engineering (CeNSE), Indian Institute of Science (IISc) and scientific consultant on High Technology Industrial Application to the principal advisor to Government of India.

Indian micromachining industry With the need for miniaturisation, the field of micromachining has grown at a rapid pace worldwide in the last decade. However, the Indian industry is yet to pick up this technology with the same fervour as other countries. Even as the Indian machine tool industry has matured in machining technology, micromachining is still at a nascent stage in the country. “Micromachining has not yet come to the Indian industry. Even in the western world, it is yet to become a mainstream activity. A lot of work is happening in this area, more so because machines and equipment are becoming smaller and components are becoming tinier. Research in the nano field is bringing in a lot of change by generating more efficient materials which in turn is giving a lot of scope to develop smaller parts. Few Indian companies are into LED moulding and manufacturing which is small in size, but not small enough to be classified as micromachining,” feels S Subbarayan, Deputy General Manager - Die Mould, Makino India Pvt Ltd. Given the lack of adequate research for technological upgradation in this segment, the industry is still staggering to incorporate high-end micromachining in its machining process. Adding to it, the high investment needed to imbibe this technology is yet another deterrent for this industry. However, industry experts are optimistic about the growth in this area over the next decade.

For cutting-edge accuracy and precision In the 20th century, researchers and user industries realised the benefits of miniaturisation in terms of reduction in space, power consumption and cost. Miniaturisation also led to the reduction in weight of the devices. With this growing demand for miniaturisation, integration of laser micromachining into production processes has proven to be a cost-effective alternative instead of traditional techniques. Prof V K Jain

n the last four decades, there have been tremendous developments in the field of computer technology. This has changed the scenario of miniaturisation in different types of industries, including machine tools (NC, CNC, DNC), telecommunication (land line phone and now mobiles having many features of computers), televisions etc. All these miniaturised products could be made by additive processes (rapid prototyping, focussed ion beam, etc), forming processes (micro forming using laser, plasma, incremental forming etc.), micro-moulding processes (LIGA, etc.) 72

or subtractive processes. The last one is based on micromachining or nanomachining using laser beam, electron beam, electric discharge, electrochemical anodic dissolution, electrochemical spark, ultrasonic etc.

Laser technology revolution The integration of laser technology enhances the need of miniaturisation and Laser Beam Micro Machining (LBMM) plays an important role in miniaturisation in spite of its weaknesses in terms of heat affected zone, recast layer, low aspect ratio

features and capabilities of making only 2D features. This process works on the principle of material removal by melting and vapourisation of the work piece material by supplying concentrated high intensity heat at the focal point of the laser beam just like an ordinary light. In LBMM, the laser light is concentrated. Many times, to assist the process, a gas is also used. However, with technological advancements, some lasers have been developed which lead to the heatless laser ablating process like excimer laser, pico second laser and laser femto second.

Is India equipped to replace conventional machining solutions and imbibe high-end laser technology? A lot is being predicted about the future of micromachining technology in India. Even as the countryâ&#x20AC;&#x2122;s manufacturing sector is under the pressure to deliver growing volume, research and development on next-generation technology has taken a back seat. In such a scenario, is the country really ready to adopt high precision laser technology in micromachining still remains a big question. Debarati Basu talks to industry experts to find out the fate of this technology in the country.

The Indian industry will be able to incorporate high-end laser machining. The need for new products will drive the market and demand for this technology will go up. Lot of work is happening abroad, but in India, it is yet to pick up. Some basic research is happening in the premier institutes but manufacturing by itself has not yet come to India. As the basic research progresses and translates into advantage for the end user, this industry has to grow. India is already picking up the trends of miniaturisation. Seeing the progress, it should be a part of the Indian industry in a decade.

The manufacturing sector in India has not grown as it should have grown. Our counterparts in China, Japan, Taiwan, Korea and Malaysia have grown in a big way. Our machining is limited to duplication of some of the systems for conventional purpose. The research and technological development has to go hand in hand with the users requirements. With the numerous foreign collaborations coming into the country, this is the best time when the Indian industry can make the most of the global technology which is at its disposal. The industry, government and scientific institutions should work together.

In India, the industry is at par with the foreign industry and is using the technology very effectively, but the machine building industry is still lagging behind. The machine that we build is not supreme in terms of technology and accuracy. The kind of research and development required is still not happening in India. However, we cannot fully blame ourselves as the modern era of machine tool industry of India is just half a century old. We cannot face the western developments head on but we can try to improve. Government can play an important role by helping the industry to grow.

Micromachining technology in India is at a nascent stage. Especially, in the machine tool industry this is an exotic area. The key is to generate adequate demand to justify the investment. With the growing importance of nuclear and space technology, both domestic and international, there is an opportunity for significant growth here. Indian industry is slowly moving towards micromachining as it discovers the capability and cost benefits. Several companies have established facilities in the country and in time will need an ecosystem of suppliers, capable of meeting the high quality requirements.

EDITORIAL TAKE The country needs to raise its bar in the area of research and development to incorporate new technology and ensure high-end machining. However, the need of high investment in the present industry scenario is coming in the way of incorporating high-end research. The government and scientific institutions need to take a lead to provide better and cost-effective solution to the industry. 76

Once the capability comes, the applications are many Medical science in India is at its best but machining of medical equipment has not yet entered the countryâ&#x20AC;&#x2122;s manufacturing circuit. With the world aiming for better medical aid, the machine tool industry is trying to achieve the sub micron level of accuracy required in this segment. S Subbarayan, Deputy General Manager-Die Mould, Makino India Pvt Ltd points out to Debarati Basu the measures needed to take to make a breakthrough in manufacturing high precision medical equipment. Q With the need for

precision, what is the role of micromachining in the medical sector? The medical industry is one field where micromachining is playing a very important role. The western market has come up with lot of applications using micromachining in this field. Micromachining is not restricted to milling. Initially, micromachining was restricted to Electric Discharge Machining (EDM) and laser machining. Research on micromachining has been happening for almost a decade. Milling technology then, was not capable of handling very small cutters. But today

high speed milling is able to do so. Many EDM job functions are now handled by milling process. The efficiency of milling has gone up tremendously today. In the medical industry, there are numerous parts which require micromachining. For instance, micro motors required in robotic surgery, the actuators, biopsy scissors and equipments attached to endoscope. Some of the implants like orthopaedic screws, dental dentures etc are also picking up. Once the capability comes, the applications are many.

Q The Indian medical industry is

still in an evolving phase. Tell us about the industry growth.

This field of machining has just grown in the western world. However, medical micromachining is yet to come to India. The closest to small size machining that the Indian industry has reached is LED moulds. Even there, most of the moulds are imported. It is very popular in the far-east like Singapore, Malaysia, Thailand, Taiwan, Korea and Japan because of the fabrication facilities available there. Micromachining for the electronic industry (IC molds, fabrication etc) has been tried, tested and have been flourishing in these countries over the last 10 to 15 years. It requires huge investments and these countries cater in November 2011 - MODERN MACHINE TOOLS

Interface: S Subbarayan huge volumes to justify that investment. The machining of medical parts in India is in a very primitive stage. India is able to meet its basic needs of medical equipments like screws, dental implants, orthopaedic implants, basic surgical equipments like scissors, forceps etc. The country also manufactures syringe moulds, rubber parts for intravenous catheters and other accessories since the demand is high. However, more complicated parts like knee or hip joints, which require complex five axis machining is not yet manufactured in India. We, of course, have simpler designs of the same which are low-cost and not so complex to manufacture. Medical components and devices which involve very high degree of complexity are still manufactured abroad and imported here. Those parts which are tested, proven and consumed in large numbers are being manufactured in India.

Q The medical fraternity has

evolved in the country and today India is tagged as one of the most cost-effective destinations for medical assistance. Why is not this demand generating interest among the machine tool builders to develop highend medical equipment and solutions? Making the medical parts with the help of micromachining requires an entirely different skill set. While there is a lot of research happening in medical science, where is the research happening to make high precision machines and medical parts? India forms one of the biggest customer base for importing the medical equipment and parts but we are neither at the cutting edge of research nor are we developing new products. The prototypes are being developed in foreign countries. However, one big shift that has happened in the global industry is that today products are developed keeping India and China in mind.

Q Is laser technology picking

up in the medical machining fraternity? 82

MODERN MACHINE TOOLS - November 2011

Laser has its own limitations and advantages. Laser can remove material but its removal capability is low compared to the metal cutting process. But laser can work well on hard materials and very shallow removal of materials. It is being used selectively. In this case, micro milling and laser micromachining complement each other.

Q What are the new materials that

are being used in the manufacturing of orthopaedic parts and medical implants? What are the latest trends which are coming up in this area? Specialised steel and non-corrosive steel are some of the materials which are picking up in this fraternity. Specialised steel is especially being used in orthopaedic parts. Titanium however is used more in implants because of its special properties of being one-third the weight and twice the strength of steel. Because of this, it is one of the most preferred materials in implants. But it is also expensive. Titanium has its own limitations in machining, but this material has been earlier widely used in other industries like aerospace. The metal cutting process of titanium has matured in a very big way over the years. So, machining titanium in medical applications is seeing the next big leap in machining. Whichever be the material, the moment the size becomes smaller, it poses a major challenge on the machine tool builders to develop spindles to handle such small tools for machining. Another major concern in using these materials is the use of coolants and other chemicals that is used during the process. These coolants and chemicals might have a long-term impact on the basic material or impact the performance of the implant inside the human body.

Q What are the challenges

faced in machining of medical devices and equipment? Material is not the major challenge. The size of the material, holding the material and

having a machine to cut the features to the accuracies defined, is a bigger challenge. Major challenge in micromachining is to have thermally stable machine designs. When we talk at the micron level, the part itself is around 2~3 mm, the accuracy is in microns, so the overall mechanical structure has to be thermally stable. Any variation in the temperature can affect changes in the structural elements of the machine which can lead to dimensional errors. Designing a machine that is thermally stable and also building a mechanism that ensures a constant temperature for the machine is the key to achieve that accuracy. Apart from the external temperature, we also have to take care of temperature changes caused by heat sources inside the machine. Anything that runs on high speed will generate heat. We have to ensure that the heat generated from the spindle or motor does not lead to dimensional errors in machining. We have to control or extract that heat for which specialised cooling or thermal isolation mechanisms needs to be in place. After all these measures, there are compensation techniques which compensate errors that still remain. Online measurement techniques are taking a lead today which measures the positions and compensate for the errors. These are very critical technologies which have been exclusively developed for micromachining.

Q How do you foresee the

future growth of this industry in India? Our demand for non invasive surgery or laser technology in medical field is growing, but the masses still go for low cost options. The demand is yet to pick up so the volumes are not there. Also, within the medical fraternity the skill sets to handle this technology is still limited to bigger cities. Developing these products and technology and handling these machines is in itself a different league of work. People are still not confident. However, it is a matter of evolution.

Things are changing, but the change needs to happen at a faster rate With the manufacturing sector undergoing a paradigm shift in the way materials are machined, laser technology is building the foundation for a machining revolution. The world is looking forward to high precision machining with absolute accuracy in carving delicate geometries. Prof S Mohan, Visiting Professor at Centre for Nano Science and Engineering (CeNSE), Indian Institute of Science (IISc) and Scientific Consultant on High Technology Industrial Applications to the Principal Advisor to Government of India tells Debarati Basu how this technology will be a milestone in machining. Q The use of laser technology is

the upcoming mode of machining in industry. How has this technology evolved with the need for precision machining? Laser machining technique had first come up for the semi conductor industry but it was later found to be more effective for machining exotic materials. This technology also has the advantage of giving high accuracy and reducing wastage of materials to a large extent.

With its advantages of making corrections, controls, feedback and further correction, lasers were preferred over the conventional machining systems. However, maintenance of the systems, running the systems without much down time and also catering to the requirement is a huge challenge. There is still a need to make the industry and the customer aware of the facility. With laser technology, the cost factor is yet another hurdle. Because of this, laser machining is used only in niche areas.

The machine tool industry has been using this technology for some time now, but it has not yet reached the sub micron level of accuracy. However, it is only prevalent in specific applications of defence and aerospace which needs that level of accuracy. Also, machining of exotic materials like titanium or diamond, where the wastage of the material has to be significantly reduced, needs to be machined using laser technology. The machine tool industry per se, does not have such requirement yet. November 2011 - MODERN MACHINE TOOLS

Interface: Prof S Mohan Taking into account the cost factor, the implementation of this technology would be a huge investment for this industry as the machine tool industry is just a minor chunk of the manufacturing industry. Like in the foreign countries, this industry needs to broaden its base and bring other industries like diamond cutting tool industry, semi conducting, biomedical etc under its gamut. We cannot restrict manufacturing to just machine tools. Such technology for a small gamut of work would be too expensive. The same technology for a bigger industry would justify the investment made. The machine tool industry should aim to get benefited by its involvement along with the entire manufacturing industry in latest R&D.

Q What are the parameters

that scientists across the world are trying to achieve with laser micro machining? Laser micromachining has already come into place. The systems are becoming micro systems, also known as micro electro mechanical systems. Miniaturisation is becoming a trend and machining now needs to be done using lasers, plasma, electron beam and ion beams. From laser machining to an accuracy of 1 micron, one can go to an order of 10 mm which is one hundredth of a micron which requires electron beam lithography. The accuracy in such machining is undergoing an unimaginable transition from micro to nano. Watch manufacturing might need micro systems. But for a system like blood pressure monitoring, where a small chip needs to be integrated inside the body giving information about the sugar content and which also should have a small insulin tank integrated in it, one micron is not sufficient. The kind of motors and sensors which needs to be embedded into the body for such a system only defines the level of accuracy that the micro machines and machining process of tomorrow will have. However, the machine tool industry does not require this accuracy yet. 84

MODERN MACHINE TOOLS - November 2011

The latest trend that the machine tool industry is picking up is that of machine health monitoring sensors. To maintain the accuracy in machining, the â&#x20AC;&#x2DC;healthâ&#x20AC;&#x2122; of the machine needs to be monitored. Today, we do not just want to sense the temperature and pressure in the machine but also want an intelligent machine which can correct the variations automatically. That is a new revolution today where the temperature, vibrations, pressures and various other factors affecting the machining process can be monitored and rectified. For this, the sensors need to be embedded inside these systems. These sensors cannot be large in size as larger sensors consume some temperature and do not give the correct value. Hence the sensors have been miniaturised. In another five years, the Indian machine tool industry too will require such nano sensors.

Q Which are the industrial

sectors that will demand laser micromachining in future? It is already playing an important role in aerospace and defence sector not just in machining the parts but also in terms of having online health monitoring system for the aircrafts. This saves time in manual inspection of the parts every time the aircraft lands and gears up for its next take off. With micro sensors, the pressure and temperature of wings, turbines and other parts of the aircraft is constantly monitored. The machine tool industry or any other industry where cost is a major factor would not use this technology. But if there is a demand which triggers mass production, the cost will come down.

Q The industry today is using

exotic materials like titanium, composites etc. How effective is micromachining for machining these materials? It depends on the application. If the material needs to be compatible with

human body, titanium or silicon is the preferred material. Use of material at a very high temperature like space aircrafts needs materials like silicon carbide which is also one of the most difficult to machine materials and needs to be machined using ion beams and lasers. The automotive industry needs materials which are high in strength and light in weight. As such machining requirements are different for different applications.

Q What are the challenges and

loopholes that scientists are trying to eradicate in the micromachining process? The requirement does not stop at the use of materials or technology. The industry has to penetrate deeper and take the most intricate details into consideration. The choice of tool bits and applicable coating, the metrology and the health monitoring of the machine also plays an important role. It would take a lot of research so that the industry can work in the direction of achieving nano level of accuracy.

Q Does this technology help

in minimising waste and optimising the available resources? The industry has to start thinking about green technology. Machining involves a lot of material wastage and effluent release. The time taken to do the operation is long and power consumption is more. The latest in this sector is the use of nano lubricants which reduces wastage and decreases the pollution level, power consumption and machines the material faster.

Q How do you foresee the

future of this technology in India? The industry needs to be aware of the latest technology and educate the scientists and together, along with the government we need to bring a change. Things are changing, but the change needs to happen at a faster rate.

Efficiency through innovation EDM provides an effective manufacturing technique for producing parts made of special materials with complicated geometry. These products are usually difficult to produce by conventional machining processes. Industry testing indicates that todayâ&#x20AC;&#x2122;s

technologically advanced EDMs do not damage the surface of the material as was the case in the past. Similarly, the advantage of controlling the process parameters to achieve the required dimensional accuracy and finish has placed this machining operation in a prominent position. Over the years ,the cutting speeds have improved from 10 to 20 per cent on average. These higher speeds have been possible from a combination of technologies, including refined power supplies, increasingly

EDM prospects sophisticated software, higher pump pressures, and specialised wires. EDM now provides one of the best alternatives, or sometimes the only alternative, to machine a growing number of highstrength and corrosion & wear-resistant materials. As a result, manufacturers now are able to use this technique to manufacture more components and possibly eliminate secondary machining operations, there by reducing costs and decreasing delivery times. Cutting-tool manufacturers find wire EDMs attractive because electroerosion reduces the wastes of the expensive raw material, and needs no secondary grinding or buffing to finish the tools. Cutting speeds are similar to grinding and, in many cases, outpace it. The resulting efficiencies shorten delivery time and reduces the overall cost of manufacturing. For these reasons, electro-erosion has become cost-competitive with hard milling in some applications. The highnickel steels and titanium alloys used in medical and aerospace parts have a negative effect on the cutters but by using EDMs companies can save on their operating cost.

Business prospects Companies are on the look out of new products and innovative process to give them an edge over their competitors. They want novel ways to do their specific application at a much more cost-effective price. The production of many consumer goods, from cell phone cases to automobile components, relies on moulded parts. The mould cavities needed to produce these parts often are created through the application of EDM. Modern EDM machines have significantly evolved from their predecessors. EDMs now have additional features like the ability to integrate with other machining processes as well as automate them, ability to machine nano parts, download computer-aided design files directly and convert them into machine codes, and drill fine holes. Both wire and ram are widely accepted by manufacturing industry, with die 96

How EDM increases efficiency

Achieving difficult geometries such as long narrow slots and sharp corners Racking and stacking of parts to achieve economies of scale The ability to cut any conductive material Reduced tool wear Hardness of parts does not affect cycle time Very accurate tolerances can be held up to 0.0001 inch Burr free finishes Time for machining is less than normal machining process

and mould making companies showing especially strong interest in the latest technical developments. These advances reflect the trends and changes impacting the metalworking industry driven by growing demand for highly tolerance work delivered on very tight schedules. EDM provides a means of machining ceramic materials, irrespective of their hardness and strength. Detailed testing has shown EDM machines produce recast layers of less than 0.0004 of an inch. EDM processing offers many distinctive advantages, chief among them being its ability to cut difficult contours. Also, wire-cutting EDM can handle some of the hardest materials used in the tool and mould making industry. Toolmakers can use EDM to create intricate profiles that they could not achieve with other metal-cutting methods. EDM achieves high removal rates as compared with traditional techniques for the machining of these materials. Unlike conventional machining techniques, there are no cutting forces involved so the process is ideal for machining delicate parts. The lack of correlation between the cutting rate, the surface roughness and the physical material parameters confirms that the removal mechanisms for machining conductive ceramics differ from those involved in metal machining. The complex workpiece geometries and high accuracy to shape

and size attainable with electro-discharge machining particularly favour its use in toolmaking. There are various types of products which can be produced using EDM such as dies and moulds. EDM is also being used for decades to manufacture aerospace parts including engine, fuel system, and landing-gear components, as well as other high-stress, hightemperature parts. EDM also finds application in the manufacture of parts for surgical tools, implants, and other medical devices as it is better suited than traditional machining to cut miniature parts. Conventional machining necessitates that holding forces overcome cutting forces. While manufacturing small parts, holding or clamping parts can damage or even destroy them, while cutting pressures can bend or deflect thin sections and heat can change the material temper. Since in EDM there is no physical force on workpiece, it greatly simplifies workholding and allows even delicate parts to be machined. Also, the application of EDM in medical device, fiber optics, gas turbine, and oil industries, have remained strong. Depending on the application, EDM operations may be performed with a simple manual machine or by means of sophisticated systems that include robotics and ID chips incorporated in the tooling for traceability. The manufacturing industry has recognised that EDM is a valuable, viable process to manufacture components and parts. The growing use of EDM in a variety of end-user industries such as medical devices, electronics, automotive, metalworking and parts manufacturing will drive the demand for EDMs in coming year. The benefits of doing far more precise job in lesser time due to the contactless machining process, makes EDM the preferred choice within many end-user industries. As customers realise the advantages of these technologically superior machines that can perform multiple functions, EDMs are expected to witness greater demands in the near future.

Charging the machine tool industry When it comes to machining difficult to hard materials, producing complex shapes, reducing cost, providing precision and increasing efficiency, Electrical Dicharge Machining (EDM) has become a necessity. Right from its inception, EDM has come a long way to become one of the key machining techniques being widely used in the industry. Driven by the demand from sectors like aerospace, die & mould and automobile, it will continue to grow at a rapid pace.

in the latest technical developments. Many latest technical developments are likely to come from the EDM equipment builders. These advances reflect the trends and changes impacting the metalworking industry, where a severe labour shortage collides with a growing demand for highly-toleranced work delivered on very tight schedules. EDM is clearly emerging as an indispensable technique for meeting these challenges. Shop owners and plant managers are quick to exploit the growing potential of EDM in their production strategies. Manufacturers have mastered the art of turning small technical advances into decisive competitive advantages and have learned how to plan and execute these plans with intense discipline and faithfulness. Processes such as high-performance milling and rapid tooling are competing for some of the applications traditionally produced with EDM. Despite the technical strides that these processes have made, EDM has maintained a dominant position in mould-making. This is largely due to vast improvements in wire EDM processes. There are two primary EDM methods: Ram EDM and wire EDM. The primary difference between the two involves the electrode that is used to perform the machining.

Ram EDM In a typical ram EDM application, a graphite electrode is machined with traditional tools. The speciallyshaped electrode is connected to the power source, attached to a ram, and slowly fed into the workpiece. The entire machining operation is usually 100 MODERN MACHINE TOOLS - November 2011

performed while submerged in a fluid bath. There are many operations where ram EDM is the most efficient way to machine parts. It can machine a wide variety of shapes and sizes, including sharp corners. Also this non-contact machining method with low-pressure flushing allows it to produce very thin sections. Ram EDM can also be done in the vertical or horizontal position.

Wire EDM Also known as spark EDM, wire EDM machining is an electro-thermal production process in which a thin single-strand metal wire in conjunction with deionised water allows the wire to cut through metal by the use of heat from electrical sparks. Due to the inherent properties of the process, wire EDM can easily machine complex parts and precision components out of hard conductive materials. It works by creating an electrical discharge between the wire or electrode and the workpiece. As the spark jumps across the gap, material is removed from both the workpiece and the electrode. Wire EDM is commonly used when low residual stresses are desired. Wire EDM has no added residual stress because it has no cutting forces. There is little change in the mechanical properties of a material in wire EDM due to its low residual stresses. It has ability to be programmed and cut very intricate and delicate shapes. The ever-changing face of technology looks to play a valuable

part in resolving some of the current dilemmas in the EDM industry. Enhanced machining speed and unattended operation are solutions to the problems of compressed delivery times, competitive pricing and lack of skilled labour.

Automated EDM With modern wire EDM machines utilising CNC for production, there is a user-interface device, the computer, where the operator feed the required data for design that will eventually guide the wire EDM machine during the passes and cuts in the process of creating the final product. Moreover, like any computer today, software is needed to run the equipment. This is no different in wire EDM. The CNC controller and the software application comprise the wire EDM technology.

Limitations of EDM machining

It requires very high power supply It is useful only in conductive material machining Reproducing difficult corners and fillets Cracking may occur

There are numerous wire EDM technology software applications for wire EDM machine CNC controllers, nearly all of which integrate with varying CAD/CAM software. Today, developers can create the object in AutoCAD, designing tensile strength, variances, etc. and provide that to a wire EDM shop that will then plug this design into the wire EDM technology software, which will in turn drive the machine, turning out the final product. EDM machining is suited to working with very hard or difficult materials such as hardened tool-steel, titanium, carbide and inconel, which makeks it reliable, precise and fine tolerance machining process. EDM has gained wide range of acceptability as it increases efficiency by increasing production capabilities.

For improved efďŹ ciency quotient EDM is among the earliest non-traditional manufacturing processes, with it being used 50 years ago in a simple die-sinking application. Since then, manufacturing industry has seen rapid development in EDM, which has become the main machining process. In recent time when industries like aerospace, automotive and energy are demanding new raw materials and alloys it becomes imperative to introduce and extensively use advanced technology like EDM.

ew developments in Electric Discharge Machining (EDM) need to provide both flexibility and better automation. Users want to minimise worker training and increase the number of tasks each unit can perform. For example, EDM finishing of pre-milled cavities is a major task. Earlier, the EDM electrode would follow a pre-programmed orbit cycle without considering the shape that was premilled. With the new design, the operator describes the orbit pattern needed. A machining method typically used for hard metals, EDM machining makes it possible to work with metals for which traditional machining techniques are ineffective. An important point to remember with EDM machining is that it will only work with materials that are 106 MODERN MACHINE TOOLS - November 2011

electrically conductive. With good EDM machining equipment, it is possible to cut small odd-shaped angles, detailed contours or cavities in hardened steel as well as exotic metals like titanium, hastelloy, kovar, inconel and carbide. The EDM process is commonly used in the tool and dies industry for mouldmaking. However, in recent years EDM has become an integral part for making prototype and production parts. This is seen in the aerospace and electronics industries where production quantities remain low. Because of its capability to machine hard to machine materials EDM has gain huge acceptance in the aerospace, automotive, die & mould and electronics industries.

Advantages of EDM For creating complex or simple shapes

and geometries within parts and assemblies, EDM is one of the most accurate and suitable manufacturing processes available. It works by eroding material in the path of electrical discharges that form an arc between an electrode tool and the work piece. EDM manufacturing is quite affordable and a very desirable manufacturing process when low counts or high accuracy is required. Turn around time can be fast and depends on manufacturer backlog. The EDM system consists of a shaped tool or wire electrode and the part. The part is connected to a power supply. Sometimes to create a potential difference between the work piece and tool, the work piece is immersed in a dielectric fluid which is circulated to flush away debris. The cutting

EDM techniques pattern is usually CNC controlled. Many EDM machine electrodes can rotate about two-three axis allowing for cutting of internal cavities. This makes EDM a highly capable manufacturing process.

EDM in aerospace Two major factors have contributed to the evolution of EDM from a tool-room to a production process. Firstly, the aircraft industry had a requirement for the high-volume manufacture of precision components using the exotic, difficult-to-machine materials such as Hastelloy, Nimonics, titanium, etc. Secondly, it provided the capability of high productivity, with economies in space and manpower. EDM has been used for decades to manufacture aerospace parts, including engine, fuel system, and landing- gear components, as well as other high-stress, high-temperature parts. Throughout its history, however, the surface integrity and thereby safety of EDM-machined aerospace components has been questioned. As a result, aerospace manufacturers tightened their specifications on EDM-manufactured parts, requiring post-EDM secondary processing such as machining and chemical etching, or both. In many cases, it had been declared that EDM was not an acceptable process for the parts in question. The aerospace industry has recognised that EDM is a valuable, viable process to manufacture aerospace and aeronautical components; however, early EDM machines compromised the surface integrity of these components. Therefore, secondary machining operations, including grinding, milling or chemical etching, were required to remove recast, HAZ and micro-cracks. Industry testing indicates todayâ&#x20AC;&#x2122;s technologically advanced machines do not damage the surface of the material as in the past. As a result, aerospace manufacturers now may be able to use EDM to manufacture more components. Manufacturers could possibly eliminate secondary machining operations, reducing costs and decreasing delivery times.

Increasing efficiency The latest generation of EDM machines provide, pretty much as standard, 5-axis capability, the direct import of 3D solid modelling into the numerical controller, very less graphite electrode wear rates. Designers are enthused by the latest option to upgrade the controller to handle 8-axis simultaneous electro discharge machining. This eliminates multiple setup operations, while removing the complexity of integrating additional controllers to achieve the same machining capabilities. It can also machine highly complex geometries out of a single piece of material, provide added strength and integrity, dramatically increase machining flexibility and enable the creation of forms in 3-D that are limited only by the technical imagination of the design engineer.

Unmanned machining is a trend that is catching up in India …avers Deepak Shrivastava, Executive Director, Electronica Machine Tools Ltd. He is an industry veteran with more than three decades of experience in Electrical Discharge Machining (EDM) and wire EDM. In a candid conversation with Swapnil Pillai, Shrivastava talks about the growing application for EDMs in India driven by robust manufacturing industry. Q How has the EDM market

matured over the years? What were the challenges that your company faced in its starting years? EDM is a very unique and guarded technology and finds its origin in Russia. Very few countries in the world have the technical know-how of this technology and India is one among them. Our company started with EDM, but because of import restriction the technology upgradation 108 MODERN MACHINE TOOLS - November 2011

was very limited until 2002. Everything related to EDM or wire EDM development had to be done in house. In EDM or wire EDM, even though the technology is same everywhere, the mechatronics differ. The development and availability of these mechatronics play a vital role in making a machine. Since there were a lot of restrictions in the import of the components related to mechatronics, all our energy was channelised into developing these mechatronics.

Q Elaborate on the R&D

initiatives undertaken by the company to meet the growing demands of the industry. The demand for consistency is playing a big role in driving the R&D into EDM. It has been our belief that if the company has to grow, the market share has to remains the same and increase with corresponding increase in market size. This can be achieved by giving the customer the best and the

Interface: Deepak Shrivastava latest technology. As per our growth vision of 2015, spending on R&D is an integral part of the budget. Our aim is to offer our customers the best cost to performance ratio. Towards this objective we have been consistently investing 2-3 per cent of our turnover into R&D since 2004-05 and in the past two years it has increased to almost 7-8 per cent. These investments are mostly diverted to the development activities being done in Geneva with a focus to bring in the latest technology. The integrated R&D unit at Saswad with around 40 people also plays crucial role in the development of the latest machines.

Q EDM being a highly

technical industry, brief us about the training & development initiatives of the company. We have our own dedicated team of hardware, software and mechanical engineers who take care of the five integral functions of EDM. Out of a total of 400 people, we have around 200 engineers on a pan India basis. Out of these 40 are into R&D. We refer to the EDM process experts as â&#x20AC;&#x2DC;application engineersâ&#x20AC;&#x2122; and have structured training programmes for them. We have few application engineers in the factory, some in development site and some are spread all over the country. We also work very closely with technical institutes like IIT Kanpur and Mumbai, College of Engineering, Pune on new projects related to EDM.

Q How has EDM evolved

as a process in terms of application and technology? Speed, accuracy and finish are the three performance parameters by which EDM is accessed. There have been developments in these parameters around the world. Over the years, the cutting speed has increased 8 to 10 110 MODERN MACHINE TOOLS - November 2011

times. Our focus is on offering cost to performance product to the customer. By performance, we mean that the customer gets sufficiently good speed, accuracy and finish which is as per the industry standards.

Q Brief us on the recent

trends in EDM. Unmanned machining is a trend that is catching up in India. The machines are equipped with automation softwareâ&#x20AC;&#x2122;s, so that in case of any bottlenecks like power failure, the machine automatically resumes work. Similarly, getting a good operator is major problem, which is solved with the help of automation. Machine intelligence is also gaining prominence in the industry. Based on the intelligence, the machine calculates the best operating settings based on the end product specification that is entered by the user and delivers output.

Q With the growing use of

composites, what are the advantages that EDM has over traditional machining techniques? Wire EDM is used extensively in the press tools but with the improvement in speed and addition of new features, these machines are finding wider applications in mould making industry. Similarly, carbide can only be machined effectively using wire EDM. Traditional machining techniques will always have a problem in machining touch materials and the cost of cutting these materials is also very expensive. With the growth of aerospace and other technically advanced industries that

use inconel, titanium and other hardto-machine materials, the demand for EDM will increase. Similarly, micro EDM is playing a crucial role in the medical industry and the manufacturing of jet engine turbine cooling. Micromachining is growing and micro EDM is finding acceptance in this regards.

Q With abundant

opportunities for machine tool makers in India, how do you foresee the demand for EDM and what are your plans to cater to the growing needs? As per the industry figures, the consumption for machines tools stood at around ` 15,000 crore for March 2011. Out of this figure only 30 per cent of machine at ` 3,500 crore were manufactured in India. IMTMA projects that this figure will grow to reach ` 50,000 crore by 2015-16. So, the theme of IMTMA is to expand the market share of Indian manufactured machines so that we have a 50 per cent market share at ` 25,000 crore. Now, if we correlate the demand for EDM with the consumption of machine tools, we project the market for EDM to be around ` 300-350 crore in the coming years. To meet this growing market, we have our plans ready. We are enhancing our machining capacity and have recently bought around 10,000 sq ft facility in Pune to cater to our machining requirements. At Sasad, we have added around 40,000 sq ft to our existing plot of 280,000 sq ft. Our company is also working on a compact machine to be showcased at IMTEX 2013.

EDM, metrology system pairing opens new doors Seeking a solution for producing and measuring smaller, more intricate parts, this shop combined a ram EDM unit and optical 3D metrology system. Each provided significant benefits on its own, but the pairing of the two technologies enabled the company to achieve new levels of precision and productivity.

EDM from Makino (Mason, Ohio) with the Infinite Focus optical, 3D metrology system from Alicona Imaging (also based in Bartlett) has enabled the company to reach levels of accuracy and repeatability that outclass anything it had previously achieved. As a result, the company has saved both time and money while bringing in new work. “We have a bright future ahead of us with a whole new list of clientele that didn’t exist before, and we have these two technologies to thank for that,” says Mark Raleigh, company CEO. EDM Department provides flexible manufacturing services to a range of industries, including aerospace, defense, medical and telecommunications. Raleigh founded the company with a vision that it would invest equally in its technology, resources and customers. “We operate under the premise of three business models in one,” he explains. “We have a research and development facility, a production facility, and a turnkey solutions facility.

EDM Department, a Bartlett, Illinoisbased contract manufacturer, is a case in point. Uniting a high-precision EDAC1 ram

ensuring a competitive stance in the global market,” says Raleigh. Maintaining that competitive edge, however, has become more difficult in recent years amid an increase in smaller, more challenging work and numerous design reviews, says Raleigh. He notes that when the company first considered adding to its machining capabilities, it was already producing features and elements at the 100-micron level. Today, 25-micron features are common. Some work even requires 10 microns. The company needed a robust solution that would enable it to measure tolerances on a 1-micron scale, and Makino’s EDAC1 ram EDM did not disappoint. Running the machine through a gauntlet of positioning, surface finish and general machining tests revealed that it was actually more capable than anyone had anticipated, says Raleigh. The machine is capable of producing corner radii measuring 0.00019 inch (0.005 mm) and surface finish quality of 0.000024 inch (0.6 micron) Ry, and it provides submicron repeatability. It also achieves positional and pitch accuracies of ±0.00004 inch (1 micron). Thermal barriers and a Zaxis stabilizer enable cooling the Z axis and decreasing thermal growth, the manufacturer says. Additionally, the machine’s C axis and Mi head provide

Case study precise electrode positioning accuracy at multiple angles. Raleigh says the primary benefits of the EDAC1 are its accuracy and stability, which have enabled tighter tolerances and improved process capabilities. “To quantify accuracy and stability, we have to include the effect that the environment creates, so we continually reference our machine position over time,” he explains, adding , “The average daily true positional drift with the EDAC1 is less than 2 microns, and less than 3 microns during a 27-day period for the XY plane. The Z axis drifts less than 1 micron daily and considerably less than 2 microns during a 27-day period.” The machine’s repeatability has also contributed to cost savings and the company’s competitive edge by improving productivity and reproducibility, notes Raleigh. In fact, EDM Department’s return on investment since the purchase has exceeded the company’s expectations by approximately 50 per cent. “It has taken us to the next level of micromachining, and it is fully capable of what we’re trying to achieve,” he says. While the new machine provided the means to produce smaller, more intricate parts, the company still needed the ability to see and measure those parts. It found that solution in the Infinite Focus, an optical 3D metrology system designed to generate high-resolution, repeatable and traceable results. “It affords us the chance to look at what we are making and measure the surface finishes in high detail,” says Raleigh. “When other methodologies are taking 1,000 measurements, we can take millions of measurements with Infinite Focus, allowing us to enhance our end results and solutions,” he adds. Through Focus Variation, a technology developed by Alicona, the system combines the focus of an optical system with modulated light and continuous vertical scanning to produce a topographic 3D data model of a component’s surface. According to the manufacturer, capabilities include full 3D surface characterization of forms; data presentation in true object surface color; simultaneous measurement of varying surface finishes; measurement and capture of step slopes, high ‘Z’ ranges, roughness, 118 MODERN MACHINE TOOLS - November 2011

However, at Tier 1 automotive supplier Cloyes Gear and Products’ plant in Subiaco, Arkansas, this is standard procedure for the production of Variable Valve Timing (VVT) stators. The company attributes the consistent, worry-free nature of its stator production in large part to the use of a VSS-2 singlepass honing machine from Sunnen (St Louis, Missouri).

Cloyes’ Subiaco plant houses its Powder Metal (PM) production facility. Here, the company performs the entire production process for high-strength, low-weight PM parts, including both primary and secondary operations. With presses ranging in size from 60 to 825 tonne, the company achieves part densities of 7.5 g/cc in materials including iron; phosphorus iron; pre-alloyed, copperinfiltrated, tungsten-carbide/bronze matrix; and both 300- and 400-series stainless steels; among others. Key capabilities include sintering to 2,250°F; hardening via induction, carburising and carbonitriding; and a range of secondary operations. In operation, the VVT stators interface with rotors that move about 15 degrees to adjust valve timing for optimum engine performance, based on rpm and other parameters. They are made of sintered steel with a hardness of 45 HRa. A critical operation in the production of these parts is sizing and finishing the minor ID, which must be performed after induction hardening to achieve the specified 50-micron roundness tolerance and 80-micron total tolerance. The company found this operation challenging, particularly because the minor ID consists of five different segments. “We could turn this ID on a lathe, but it would be very challenging on a production basis because of the highly interrupted bore,” says Justin Carty, Process Engineering Manager at the plant.

ool life results are measured in terms of the quality of the parts machined. If the size, geometrical tolerances and surface qualities are above the levels of the requisite tolerances, it marks the end of cutting tool life. Tool life is not just the factor of cutting tool alone, but also depends on machining conditions and the various processes involved.

Factors affecting tool life The machine: Machine plays a vital role in determining the tool life. An ideal machine must have excellent spindle with good run outs and absolutely no backlash, least clearance possible in the spindle bearings and spindle dynamics during rotation. Other main criteria

that have an impact on the tool life of a machine are machine axis and its stability, internal coolant supply, etc. The right selection of the machine for a particular part is the key for ensuring optimum cutting tool life. An ideal machine should be vibration free, internal coolant supply from 10 to 40 bar pressure, spindle run outs of less than 0.003mm. The latest CNC Machines tools with HSK Spindles are ideal for optimum tool performance. Materials: Companies deal with various components like steel, stainless steel, grey cast-iron (GG), nodular iron (GGG), aluminum and other non-ferrous materials. The following are the reasons for tool wear due to material properties. Abrasiveness due to the tensile strength and hardness of the material.

Too soft to machine and long chipping and difficult to machine.

substrate and coatings alone but also the edge preparations, ‘strengthened cutting edge, new innovative chip breaking geometries like ’03‘ and ’13‘ that brings tremendous benefits of high performance drilling to increase the tool wear resistance. In case of ’fine boring’ , similar developments have noticeably resulted in big change bringing benefits in terms of not only tool life but also overall process stability, which is very important factor in fine boring. The new geometries with chip breaking topography have helped to handle difficult-to-machine parts like medium to low alloy steel and stainless steel applications. These new geometries are again offered with PVD and CVD coatings. Most important among these are cements and coated cermets, which bring highest wear resistance, thus leading to longer tool life for fine boring of all kind of steel and stainless steel machining.

W57 New style Insert for fine boring

In case of fine boring of grey cast iron and nodular iron components, the new coatings with nano-structure have been introduced with CVD multi layer coatings TiCN-TiN-Al2O3. The new technology not only does coating, but also gives a ‘special surface treatment‘ which smoothens the chip surface by avoiding or delaying the built-up edge, which increases the tool life. High speed Reaming is another important tooling solution bringing tremendous technological advantages to increase the tool life. The expandable reaming technology offers the wear compensation possible in case of tool wear. The tool diameter can be brought back to the required tolerance fields just by easy expansion of the screw. The cutting materials are made of sub-micron carbide substrate, which is suitable for all kinds of work piece material to be machined together

with Ti-N, DBG-N coatings. The other harder substrates include DST, which offers higher wear resistance to ream in all kinds of steel, stainless steel and Nodular iron. DST, being hardest substrate automatically offers to operate at a cutting speeds of Vc= 100 to 300 metres/minute, with longer tool life guaranteed. With the additional DBG-N coating on DST cutting material, the performance of the reamer can further be enhanced to extend the tool life.

Significant trends and R&D New trend of increasing the wear resistance of the cutting tool are moving towards sub-micron grade carbide substrates that increase hardness of the cutting materials, and polishing and bleating process to improve edge stability. Even in hard part milling, boring is possible with new carbide substrates that are being constantly developed and evolved. The indexable insert reaming tools are new innovations that avoids re-sharpening process and with CVD, coating are possible due to solid carbide substrate that would give benefits of increasing wear resistance. Coatings on cutting edges make a fine, yet crucial difference in the high speed of reaming. New PCD grades are being introduced for machining aluminum especially where the tool life issues are faced. For example, tool life of finish milling of aluminum cylinder head of a car can be increased by 5 to 8 times that older grades, with the introduction of new PCD grades. These new grades can also be used for reaming aluminum, which has more than 14 per cent silicon content.

Automation Trends: Growth drivers

Catalyst for manufacturing performance improvement Automation is the fundamental driving force for the growth in the manufacturing industry, which is facing intense worldwide competition. It creates an important link between technology and improvements in processes, operations, methodology. However, these systems can reach unbelievable efficiencies only when they are used by personnel with sound technological knowhow. The new trend is to overcome this scarcity by using systems that offer hundreds of man-years worth of machining intelligence. Dr Emil Somekh

ore and more organisations are finding it difficult to run their costly machining infrastructure with higher efficiencies, since these costly machines require the technological knowhow and attention of an expert, who could often minimise the trial and error cuts and turn them into safe, practical CNC programs. For example, the latest revolutionary machining technology currently available boasts of up to 70 per cent reduction in machining time as a new 130 MODERN MACHINE TOOLS - November 2011

technology feature. This is a boon to the manufacturing industry which is facing a severe margin crisis. The industry should be aware that generally most CAM systems just produce standard tool paths that mandate the need of an expert, who knows the capability of the machining infrastructure and cuts down trial and error, while optimising based on experience.

Demand for efficiency The latest technology currently available is not just a tool path, but a revolutionary

technology for high efficiency milling that links all key components of metal cutting to deliver an expert methodology. This new technology ensures that the mechanical and thermal loads on the tool remain constant, thus enabling the users to achieve maximum permissible material removal rates for given cutting conditions. This ensures that the costly machining infrastructure is run at the most optimal efficiencies, reducing machining cost and improving profitability.

While other systems generate the tool paths by keeping the cutting angle of the tool with the material constant, the latest technology uses a minimum and a maximum cutting angle, stipulated by the technology advisor as constraints (patent pending), and generates its tool paths in conjunction with matching feeds and speeds, such that the mechanical and thermal loads on the tool remain constant, a feature that facilitates deeper cuts at higher feeds than other systems.

Automate machining infrastructure In spite of the availability of such powerful productivity enhancing technologies and products, there is a probability that a large part of the Indian machining community will lose out on taking advantage of them, because of the entrenched conviction that 2D and 2.5D machining do not need any sophisticated CAM programming and can even be done on the controller, thus being in danger of wasting up to 70 per cent of their potential productivity and losing out on the use of automation to its maximum potential. Hence, it is advisable to stop using traditional inefficient machining and start cutting with the latest technology, already being used by many successful users worldwide. This is best and only way to automate your machining infrastructure.

Energy Management: Energy index

Best energy practices for manufacturing excellence Energy is a significant part of operating costs in industries as it directly affects the overall revenue of an organisation. Manufacturers are under growing pressure to comply with new environmental controls and sustainability regulations. All these factors have forced manufacturers to effectively monitor energy consumption and manage it to meet conservation requirements. Nishant Kashyap

nergy management systems are being deployed around the world to improve energy and facilities management and help reduce consumption of electricity and fuel. The Indian metalworking industry has also shown the urgency in adopting energy management into their systems. The energy management systems can assist the plant managers and corporate management in understanding and then actively managing energy use and costs. The fundamental goal of energy management is to produce goods and provide services at costs causing least environmental effects.

Importance of energy management Energy management refers to managing the effective use of energy. In this rapidly growing manufacturing world, energy management has become a key strategy to save cost and increase efficiency. Most of the manufacturer have realised that to be competitive, they must have effective energy management system. According to Aashutosh Singh, General Manager, Hind Tools India Pvt Ltd, â&#x20AC;&#x153;The growing cost of electricity and increasing environmental concerns have forced companies to have proper energy management system in the organisation. As the cost of energy directly

effects the overall revenue, companies are constantly looking for new ways to reduce energy consumption.â&#x20AC;? Effective energy management allows organisation to ensure sustainable growth through company-wide energy management policies.

Energy audit In any industry, the three top operating expenses are often found to be energy, manpower and raw materials. If one were to relate to the manageability of the cost or potential cost savings in each of the above components, energy would invariably emerge as a November 2011 - MODERN MACHINE TOOLS 133

As the cost of energy directly effects the overall revenue, companies are constantly looking for new ways to reduce energy consumption.

top ranker. Thus energy management function constitutes a strategic area for cost reduction. Energy audit will help the company to understand the ways energy and fuel are used in production process, and help in identifying the areas where waste can occur and if the scope for improvement exists. The energy audit gives a positive orientation to the energy cost reduction, preventive maintenance and quality control programmes, which are vital for production and utility activities. It also helps to keep focus on variations which occur in the energy costs, availability and reliability of supply of energy, identify energy conservation technologies, right fit for energy conservation equipment etc. In general, energy audit is the translation of conservation ideas into realities, by lending technically feasible solutions with economic and other organisational considerations within a specified time frame. The primary objective of energy audit is to determine ways to reduce energy consumption per unit of product output or to lower operating costs. Energy audit provides a bench-mark for managing energy in the organisation and also provides the basis for planning a more effective use of energy throughout the organisation.

Plant energy performance Plant Energy Performance (PEP) is the measure of whether a plant is using more or less energy to manufacture its products than it did in the past, a measure of how well the energy management programme is doing. It compares the change in energy consumption from one year to the other, considering production output. PEP monitoring compares plant energy use at a reference year with the subsequent years to determine the improvement that has been made. However, a plant production output may vary from year to year and the output has a significant bearing on plant energy use. For a meaningful comparison, it is necessary to determine the energy that would have been required to produce this year production output, if the plant had operated in the same way as it did during the reference year. This calculated value can then be compared with the actual value to determine the improvement or deterioration that has taken place since the reference year.

Environment aspects For any corporation or industry, there are many things that they must consider. Every element is crucial and needs to be managed carefully. One of the most important one is 134 MODERN MACHINE TOOLS - November 2011

Energy index keeping a proactive approach towards environmental concerns. It is important for companies to make sure that they have a good energy system. The energy system includes energy of water, electricity, gas, air, and steam. The energy system does not only affect corporation or industry, but it is also beneficial for environment. There are many tools and techniques that a company can use in order to support energy system. Each of those tools has different characteristics, function and benefit. To save the energy many software solutions are available for companies which are very useful in energy management monitoring that can control results down to asset level. This will help ensure that every element is optimised properly. By using this management service, nowadays it is possible for companies to see and control the energy system from personal computers. Such a software helps to check on any energy system in a corporation. â&#x20AC;&#x153;In these modern times,

Manufacturers can now monitor how much energy that being used and how much energy that being wasted. As a result, they can lower

the energy wasted and the cost that they have to spend for the energy system. With the increasing awareness and incentives for cleaner production, companies which have a very efficient energy management monitoring process taking place will have very good chances of availing regional and state grants for efficiency in energy use.

Policies & Regulations: Import policies

Impediment to industry growth With high inflation rate adversely affecting the Indian industry, the machine tool sector today is experiencing a jolt. Being an import-centric country, the inflation has only made it tougher for the industry as imports become a pricey deal. The industry today is hoping for government intervention for relaxation in the import policies. Debarati Basu

ver 60 per cent of the machine tool industry’s needs still depend on imports from various countries. While the Indian industry is a long way from being able to cater to its own demands, a major chunk of demand is directly or indirectly met through imports. Amidst high growth prospects for the machine tool industry in the country, the import policies imposed by the government seem to be a roadblock. The industry over the years has seen rampant growth in the engineering and 136 MODERN MACHINE TOOLS - November 2011

manufacturing sector. With new sectors emerging, India promises a huge growth potential to global market. Envisaging the growth, many foreign companies today are entering the Indian market. However, most Indian companies are crippled by the stringent import duties and policies. “The Indian industry heavily depends on imports of the inputs for the machines that we build such as CNC systems, ball screws and high precision bearing. This comprises almost 70 per cent of the total imports. There are other specialised devices like work holding equipment that the

country imports but they are not of a significant volume. We are expecting the government to support us by reducing the customs duty so that our cost of production can come down. The import duty today is almost 7.5 per cent,” says Shrinivas Shirgurkar, Managing Director, Ace Designers Ltd.

Dependence on import With rapid growth being registered in various sectors, the domestic machine tool industry is not able to cater to the market need, which further emphasises the dependence on import. “The high

Import policies rate of import duty has a direct impact on the domestic machine tool industry. The country imports nearly twice what the domestic machine tool industry produces, to meet the requirement of machine tools for industry in all segments. The share of the Indian machine tools industry in total consumption is around 36 per cent, pointing to an obvious need for the industry to further develop its products and volume to meet the requirements of the Indian user sectors. A substantial part of the imports is in specialised machines of high technology, very large machines and machine types, which are not manufactured in India,” explains N Gopinath, Vice President- Marketing, MMC Hard Metal India Pvt Ltd. The industry imports majorly from China, Japan, US and Germany along with other European countries. The global economic downturn has also played its role in affecting the Indian industry. “Currently there is a significant impact with the value of Yen which has gone up by 40 to 50 per cent over the last two years. We heavily depend on Japan for importing CNC machines and this has raised the cost of production in India by almost 10 per cent. We cannot afford to absorb this price rise and if we increase the price of our products, the demand would shrink,” says Shirgurkar. The industry today is trying to strike a balance between the growth in this sector and the price rise. Over the last decade, most of the growth in India’s machine tool industry came about with the enhanced requirements from the automotive and auto ancillary industry, defence and railways. “The Indian machine tool industry still has to depend on import of important components and the high rate of imports continues to make the cost of local manufactures uncompetitive against the import of finished machines. Also, while liberalisation has brought in easy import of high technology machines, this has impacted the technology development of the domestic manufacturers. While customs procedures have eased off quite a bit, the paper work is still complicated as 142 MODERN MACHINE TOOLS - November 2011

compared to other developed nations,” says Gopinath. High inflation rates in the recent times in no way takes off the pressure from the Indian manufacturers. Even as the Indian Machine Tool Manufacturers’ Association (IMTMA) in its latest report projected a 2.3 times growth in the demand for the machine tool industry by end of the 12th Five Year Plan, the rampant price rise does not spell good news. “The high inflation rate is definitely going to affect the growth of the industry. The RBI raised the interest rate to curb inflation and this in turn has raised production cost. In addition to this, in the past couple few weeks, the Rupee has been hammered down against the US dollar and Yen, which in turn, is pushing import costs up, leading to the increase in the cost of manufacturing. Obviously, this would be passed on to the domestic customer and eventually will have a cascading affect. Already, Index of Industrial Production (IIP) has shown signs of a slow down, car sales are down and eventually, this will affect capital purchase decisions,” points out Gopinath.

Need for government aid The small, medium and the bigger industries are looking forward for government aid and support to take hold of the situation.

“There is no policy for the machine tool industry such as the Technology Upgradation Fund Scheme (TUFS) for the textile industry. A ‘zero’ duty policy for high-end inspection equipment, and coating plants for the cutting tool industry would go a long way in increasing technology levels in India. Also, liberal depreciation rates, lower bank loan rates would help support growth of the industry. For the carbide cutting tool industry, over 70 per cent of the carbide comes from China and totally controlled by them. The cost of Ammonium ParaTungstate has gone over 200 per cent in the past year and there has been no government intervention in this matter. Most of the used tungsten carbide is exported for recycling. With tungsten carbide prices growing, it would help if the government gave some subsidy for companies who are willing to set up recycling plant. The result of this exercise will be long term,” says Gopinath. Even though the machine tool industry has continuously been in talks with the government, no concrete measures have been taken. “We have been approaching the government but the results have not been successful,” adds Shirgurkar. With the inflow of resources and global interest, the industry however remains optimistic about making ends meet and pave the growth path.

Strategy: Lean manufacturing

The way forward for metalworking industry Developed by Toyota and accepted by the world, Lean Manufacturing has become one of the key strategies in the manufacturing industry. Lean is about doing more with less, with an emphasis on less time, inventory, space, labour and money. Lean manufacturing aids in eliminating waste, simplifying procedures and speeding up production. The way mass production came to be known as the ‘production system of the 20th century’, Lean production has been recognised as the ‘production system of the 21st century’. Nishant Kashyap

e it any business, there is always scope for improvement. Whether it is eliminating waste, modifying procedures, motivating workforce to make recommendations, or just seeking better standards, lean manufacturing takes most of these into account. Over the past two decades, lean manufacturing, which is also known as Toyota Production System, has generated a greater attention and enthusiasm among the manufacturers.

Benefits of lean manufacturing Lean manufacturing is the processes, techniques, strategies and initiatives that has being implemented by companies around the world with an aim to reduce unnecessary and unproductive tasks, activities and behaviours in the work environment. Because of the high cost of raw materials, production process, manpower, energy and evergrowing demand of customers, firms are currently facing a challenge to be able to keep their profitability and efficiency intact. The advantage of implementing lean manufacturing techniques and 146 MODERN MACHINE TOOLS - November 2011

strategies is that it results in significant reduction of manufacturing time. When the manufacturing lead time is lowered considerably, it follows the operational costs incurred from the use of energy, utilities and wages. Lean manufacturing helps companies retain, maintain and increase earnings, widen their margins and help them generate savings from lower investments. Space is another area where lean manufacturing advantages are clearly and effectively exhibited. Working space is one of the primary and basic factors that helps business going.

Adoption in metalworking industry 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. Customised in nature, the products from the Indian basket comprise

conventional machine tools as well as CNC machines. 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. 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. Lean manufacturing is gradually making a mark for itself in the industry. It needs to gain pace to establish itself as a global competitor. In future, the Indian machine tool builders need to be competitive along with maintaining the quality standards, which could be possible by implementing Lean techniques in their system.

Tips & Tricks: Industry best practices

Selecting proper tool design and operating conditions for optimum machining Machining of composite materials is difficult to carry out due to the non-homogeneous structure of composites and also the high abrasiveness of their reinforcing constituents. This usually damages the workpiece and also results in very rapid wear development in the cutting tool. Conventional machining processes such as turning, drilling or milling can be applied to composite materials, provided proper tool design and operating conditions are adopted. Swapnil Pillai

omposite materials are being increasingly used in aerospace, automotive and wind turbine manufacturing. Their strong, light and thermally stable qualities are finding application in various industries, but these qualities also make it difficult to machine Machining composites is very different from machining metals, and machining one type of composite is different from

2 3

machining another composite. Moreover, the range of composite materials is broader than that of metals. Machining composites needs a reassessment of methods, tools and in some cases even machinery. Working with composites makes extra demands on part design and on the manufacturing process. Composites are highly abrasive, which means cutting tool life can be quite low. In addition,

The general principle of machining composites is to use extra-sharp cutting edges that have sufficient clearance in order to give a clean cut and minimise the tendency for the tool to rub against the workpiece. Tool sharpness is also critical. Keep all machining, drilling and cutting tools sharpened to reduce fuzzing, pitting, fraying and delamination. Tool wear needs to be absolutely minimised, as even minor geometrical changes to the edge can rapidly lead to excessive heat generation and edge breakdown and if not addressed can affect the allimportant quality levels.

To cut cleanly with the least amount of tool wear, optimising tool geometry is important. Composite drills need a severe clearance angle, and a highrake gash angle for easier entry into the material. A tool geometry designed to minimise cutting pressures is critical for cleanly cutting composites.

the low-thermal-conductivity materials do not produce sizeable chips that carry heat away from a workpiece during machining. Thus, the wrong tool can cause the materialâ&#x20AC;&#x2122;s resin to burn or melt, damaging what is often a costly workpiece at that stage of production. And because composites consist of layers of fibrous material bound by resin, they are prone to delamination and break away as they are machined.

Achieve successful performance, security and results requires establishing individual processes to suit and optimise operations and the composite materials in question.

Using the right amount and type of coolant is paramount in reducing heat buildup in resin which will minimise particulate damage

Ensure post-process cleaning of the material by rinsing it with water, solvents or appropriate materials.

Use proper dust collector for â&#x20AC;&#x2DC;dryâ&#x20AC;&#x2122; operations.

Select the right machining speeds, drilling rates and feed rates appropriate for the materials used.

Pune as a preferred choice for the manufacturing companies to establish their base in the region. The proximity to Nhava Sheva port and the presence of huge supplier base are some of the key investment drivers for this region. The bustling industrial hub of PimpriChinchwad has seen many MNCs setting up their base here to leverage on the small & medium enterprise (SME) advantage. Pune occupies an important place in production as well as export of cutting-edge engineering solutions. Satish Joshi, Director, Micro Supreme Auto Industries (I) Pvt Ltd, says, “Pune offers good transportation and logistics support, and has comparatively less union troubles. These factors have resulted in the creation of a positive environment, suitable for high growth rate and capital investment.” As per the latest figures released by the Auto

Component Manufacturers Association (ACMA), Pune has 53 large companies with a collective turnover of $ 1,400 million, and exports worth $ 235 million. Additionally, there are about 7,000 auto ancillary units in and around Pune. According to S J Gijare, General Manager - Handling Equipment Division, CTR Manufacturing Industries Ltd, “Pune was home to many ‘start-up’ SMEs in the 1960s and 1970s with hi-tech products that met the requirements of defence establishments and some large private companies. The last decade has witnessed a high growth in the SME sector with thousands of such units coming up and adopting latest manufacturing and management techniques.” Engineering Expo Pune, being organised by Infomedia 18 Ltd, is a

testimony to the rising significance of Pune in the Indian industrial landscape. Milan Supanekar, Proprietor, Welding Technologies India, observes, “Pune is a preferred manufacturing destination for automobile as well as engineering companies. This has a favourable repercussion on the development of the SME sector here. Therefore, the business environment for SMEs is favourable.”

Leveraging the legacy Engineering Expo enjoys wide media coverage and leaves no stone unturned in consistently meeting the expectations of both exhibitors and visitors alike. The previous edition of the event generated business worth ` 47 crore and more than 6,038 business leads. This has reinforced the faith of exhibitors in the event, which is evident from the fact that this year’s edition was fully booked two months in advance. Referring to the event as a gateway to Pune’s industrial opportunity, Prasanna Kulkarni, Business Manager - Industrial Air, Atlas Copco (India) Ltd, says, “Engineering Expo provides an excellent platform to interact and touch base with the customers. It enables us to not only showcase

our products but also provide live demonstrations. This interactive forum provides companies a chance to display their products and discuss the latest happenings in the industry. Western region is one of the important markets and companies will utilise the platform of Engineering Expo to create a brand that comes first in the mind of the customer and is synonymous with quality.” Elaborating further on the crucial role played by Engineering Expo in enhancing business prospects, Prashant Wani, Proprietor, Shende Sales Corporation, states, “The Expo has carved a niche for itself among professionals, and thereby attracts quality visitors. This enables us to reach a wide base of customers and generate high amount of business.” S Chandra Sekar, Senior Manager - Western Region, S & T Engineers (P) Ltd, feels that the event enables exhibitors to forge new relations with decision makers from the SME sector and corporate houses, who are regular visitors at the event. “It helps us to connect with our existing customers as well as meet prospective clients, besides showcasing our new range of products. Mainly, it gives us the opportunity to identify and interact with decision makers from various big and small companies,” he adds.

More in store The sixth edition of the event aims at empowering the visitors with latest technology. Companies can use this Expo to reinstall customers’ confidence and loyalty in the brand & take advantage of new opportunities. As Engineering Expo Pune continues its success saga, an ebullient Sandeep

Khosla, CEO - Publishing, Infomedia 18 Ltd, puts this in perspective, “Engineering Expo has come a long way today by becoming one of India’s largest multi-location (other places include Ahmedabad, Chennai, Indore, Rudrapur and Aurangabad) SME meeting points. Over the years, it has successfully delivered its goal of a preferred destination for SMEs and manufacturing & engineering companies to connect, transact, and leverage ideas to foster growth of individual organisations as well as that of the industry at large. As we look forward with further valueadditions for even better experience and reach to the target audience, we welcome large, medium & small industries in manufacturing and servicing sector to be a part of the Expo in this exciting journey.” Gijare, who feels that Engineering Expo plays a vital role in bridging the gap between business stakeholders, says, “The event enables manufacturers and traders f rom Maharashtra and other states to showcase their products and services, thereby gaining brand recognition & additional customers. Also, many visitors to these exhibitions, particularly in the SME segment, have gained appropriate knowledge and solutions to meet their specific requirements.” With the Indian industry poised to maintain the high growth momentum in the coming years, expectations are high about an upbeat investment environment in Pune. This spells excellent business opportunities for the manufacturing sector to scale new heights, and Engineering Expo Pune would act as a catalyst towards this end.

EMO HANNOVER 2011

Stimulating new business with strong global appeal EMO Hannover 2011 lived upto the expectations - as more than a trade fair - from stimulating new business across international machine tool industry to creating strong global appeal among nearly 140,000 visitors from more than 100 nations. Brimming with thousands of technical innovations, a supporting programme on Knowledge Transfer, and orders worth billions, EMO Hannover proved to be a world championship of sorts for the machine tool industry. A report…

he success saga continues at EMO! As the curtains came down on EMO Hannover 2011 – the tenth time in Hannover since 1975 – there was a commonly shared sentiment by exhibitors, visitors and organisers. In the words of Dr Detlev Elsinghorst, EMO Hannover General Commissioner, “This EMO was a winner in every respect and has earned top marks from visitors and exhibitors alike. EMO Hannover has further expanded its reputation as 168 MODERN MACHINE TOOLS - November 2011

the flagship fair for the international metalworking industry.” Adding to this Dr Wilfried Schäfer, Executive Director of the German Machine Tool Builders’ Association (VDW), the organisor of the event observed at the end of the fair, “The machine tool industry continues in full swing. In the course of the past six days, the order volume reached a minimum of €4.5 billion. Against the backdrop of an upswing in orders over the past few months, EMO’s positive

outcome means an even stronger market footing for exhibitors.”

‘Machine tools & more’ With the motto of ‘Machine tools & more’, the six-day premier event in Hannover showcased a wide array of latest machinery, solutions and services for metalworking by nearly 2,037 exhibitors from 41 different countries. “EMO has confirmed its international reputation as an unparalleled showcase for innovations. With its remarkable

EMO Hannover 2011

innovative spirit and drive, the industry is clearly making a major contribution to sustainable growth,” remarked Dr Elsinghorst. EMO Hannover 2011 reinforced machine tools industry’s innovation quotient not only in terms of impressive performance specifications, but also by highly functional and attractive design – a crucial aspect for today’s highperformance machinery. What’s more, sustainability in production formed the focus of most innovations and solutions at the event. “This EMO reflects the high priority manufacturers are now giving to energy-efficient plant and machinery. When it comes to staying competitive in the global marketplace, the efficient use of energy and raw materials is becoming a decisive factor,” added Dr Elsinghorst.

Beyond boundaries As nearly 40 percent of all EMO attendees came from abroad, the exhibitors seemed to be elated at their international prospects. To this Dr Schäfer added, “The strong international

appeal makes EMO unique throughout the industry, and is a key factor in its success. We see EMO as a reflection of ongoing globalisation. This accounts for a shift in foreign attendance, with an increase of more than 6.5 percent in the ratio of foreign visitors from outside Europe, particularly Asia and South America, which in turn has led to record-breaking figures for the duration of stay per visitor: One out of every four attendees spent more than three days at EMO 2011.” Not withstanding the financial turbulence in the European Union, one could see a positive vibe in the exhibition halls, where more than half of all visitors played a major role in their companies’ purchase decisions, as reported by the organisers. Further, 55 per cent of EMO trade visitors came to the show armed with concrete investment plans with this figure reaching 75 per cent for foreign visitors. While half of all attendees said their investments were targeted at expanding capacities, 20 per cent were planning to make firsttime purchases of machine tools. On

this Dr Schäfer observed, “There will be no rest for EMO exhibitors once the event is over. The many orders taken at EMO – on top of an already high utilisation of capacity – will have everyone working at full tilt.”

More than just exhibits EMO Hannover 2011 was not only about the exhibition. A well executed and range of supporting events made a visit to this EMO quite fulfilling. Among others conferences on topics such as sustainable manufacturing, advances in aerospace technologies, Russia as a growth market and talent recruitment for the future managed to stir intellectual discussions among participants at the fair. Hopefully, it will lead to commensurate developments in the global machine tool industry till the next EMO at Hannover from 16 – 21 September 2013.

OPTIMISING

The Northern

ADVANTAGE

The ‘Think Global… Act Local’ anthem got another anecdote. With major multinational manufacturing and general engineering companies participating in and visiting the maiden edition of Engineering Expo Rudrapur, this northern stronghold got a befitting partner. With many promises delivered and many made, the Expo concluded with a promise to come back next year with more offerings and opportunities for the participating & visiting companies. Arindam Ghosh

ew age realities spring some unwritten guiding principles. In the boundaryless market reality, it is critical for companies to establish a strong base in the local markets. This guiding principle take a different dimension when the multinational corporations have to establish a local connect and client base 170 MODERN MACHINE TOOLS - November 2011

while keeping their gaze fixed on the global trend. To combat such critical needs, many skillfully crafted ‘meet your customers’ or ‘showcase your innovations’ platforms are created. But when it is a veteran brand like Engineering Expo and an opportune location like Rudrapur, the scope and extent of such platforms multiply manifold. The latest edition of the Engineering Expo, an established trade show brand

of Infomedia18 Ltd., turned out to be a huge success in terms of its quest towards bringing out the message to the entire Indian manufacturing fraternity of a new and emerging manufacturing hub – Rudrapur – located in the state of Uttarakhand. With the aim of highlighting India’s new manufacturing hub situated in the northern belt, it indeed helped the fraternity to come together and created a conducive business environment for manufacturers to network, showcase and build brands & business, all under one enabling roof. Vikas G Patil, Incharge – Customer Care, Ratnaparkhi Electronics India, one of the exhibitors at the event, substantiated this fact. “We have been participating in Engineering Expo since the past 4-5 years and we are grateful that Infomedia18 Ltd. has given us this opportunity to participate and display our machines at Engineering Expo Rudrapur. Engineering Expo takes place in areas where new industries are coming up and I hope that Infomedia18 Ltd. keeps searching for new & lucrative places so that we can also reach there and showcase our machines,” he added. The inaugural function of the Expo saw the attendance of Chief Guest Tilak Raj Behar, MLA, Rudrapur; along with the Guest of Honour, Darbara Singh, President, Kumaun Garhwal Chamber of Commerce and Industry (KGCCI) – Uttarakhand; Meena Sharma, Chairman, Rudrapur Municipality, and Anil Sharma, Lawyer; in the presence of Sudhanva Jategaonkar, Associate Vice President, Infomedia18 Ltd. The guests highlighted the need to tap the potential of this region and offer a fillip to the industries here by providing them a conducive networking environment and state-of-the-art products & services. “Rudrapur has been emerging as an industrial destination for companies, and Uttarakhand is garnering benefits from this growth. I am sure that events such as Engineering Expo will further substantiate the importance of Rudrapur as a major industrial hub. The expanse of products & technologies on display at the event will offer a whole new gamut of opportunities for existing companies

Engineering Expo Rudrapur 2011 as well as pave the way for the growth of prospective companies in the region,” Behar pointed out.

Rudrapur shining The latest edition of Engineering Expo turned out to be an eye opener of sorts. It highlighted the potential that new manufacturer-friendly regions like Rudrapur in northern India have to offer to manufacturers. Elaborating further on the same, Singh opined, “There are many reasons why big manufacturing companies are setting up their plants in Rudrapur. Apart from the fact that the region is highly adaptable, the state government is supportive and offers manufacturers a slew of industryfriendly policies. Companies wanting to set up base here can have access to skilled manpower and resources. In addition, proximity to Delhi is one of the biggest advantages that this region offers investors.” Commenting from the organiser’s perspective on the choice of a new location for organising Engineering Expo, Jategaonkar explained, “Going by the customers’ feedback, we selected Rudrapur as our next destination. We are committed to work closely with the Government of Uttarakhand in furthering industrial growth of the state and that is the intent of launching the Rudrapur edition of Engineering Expo.” Setting up manufacturing facilities in the Tier II and Tier III cities is the new mantra for all big manufacturing companies in India. Cities like Pune, Nagpur and Indore are slowly and steadily finding space in the investment and expansion plans of the big

companies as they provide easy access to land, labour & logistics expertise, strategic geographical locations, etc. Led by manufacturing biggies, Rudrapur is fast emerging as a leading investment destination in the northern belt of the country.

Exhibitors positive on the new edition Held during September 23-26, 2011, Engineering Expo Rudrapur boasted of profuse industry participation from diversified manufacturing spaces, which included machine tools & accessories, process machinery and equipment, material handling equipment, hydraulics & pneumatics, automation and instrumentation, electrical & electronics, light and medium engineering, safety & security, packaging machinery, etc, from all over the country. Substantiating this, Patil stated, “The business generated has been quite good. A lot of potential customers had visited our stall. Based on the enquiries I received, if things work out, around 30-40 per cent of my business will come from Rudrapur.” On how he plans to cash in on the lucrative opportunities that Rudrapur offers, T N Gopinath, Director – Technical & Marketing, Suyog Rubber India, one of the exhibitors at the event, explained, “There are a number of auto companies as well as engineering companies in Rudrapur. We are located in Haridwar as we are suppliers to Mahindra, who are our primary customers in Uttarakhand. Having said that we would like to develop business in Rudrapur as it offers a potentially bigger business opportunity in comparison to Hardwar.” Highlighting the healthy relationship, which Infomedia18 Ltd. shares with the exhibitors, Arun Nene, Manager – Channel Support, Jyoti CNC Automation, one of the exhibitors at the event, averred, “Our relationship with Infomedia18 has brought us to Rudrapur.” Responding to the question as to whether Engineering Expo Rudrapur fulfilled its promises, Michael A Martyr,

Satisfied visitors The responses from visitors were quite encouraging as well. They highlighted that such events should be organised more often in future. “The expo was highly informative. More events like these should be organised here,” opined Joginder Singh, Managing Partner, J K Industries, and further added, “The event met my expectations and it has been able to meet some of my business requirements as well.” Another visitor, Papu Prasad Sharma, Manager – Electrical, Teracom, averred, “The event was well organised and the product spread was good.” Commenting on the potential that events like Engineering Expo hold, Martyr said, “Such exhibitions provide food for thought and opportunities to learn besides offering the opportunity to become a service provider to companies looking out for vendors or suppliers. I find a lot of potential in expos such as this.” Taking a step ahead and carrying this growth momentum forward, the next edition of the Engineering Expo will be organised in Ahmedabad this month.

Book Review Author: Shigeo Shingo Price: ` 695

Non-stock production: The Shingo system of continuous improvement In this book, Shigeo Shingo defines Non-Stock Production (NSP) as a cause-oriented pursuit of improvement. Shingo pulls together all the piece of production puzzle and thoroughly destroys the myth of the inevitability of waste and inventory. This book provides specific information and proven techniques that is deemed necessary to develop a successful and fully integrated continuous improvement system. It includes fundamental flaws in European and American production philosophies and basic concepts for improving production systems.

The sayings of Shingeo Shingo Key strategies for plant improvement This book contains hundreds of case studies and examples to demonstrate a scientific method for seeking, identifying and solving production problems. In this book, Shigeo Shingo describes an appropriate approach to manufacturing improvements, developed and refined over the course of time. He calls this approach ‘scientific thinking mechanism’ (STM). It is a must-read for plant managers and engineers and formalises a powerful and creative way of thinking, that the author himself has used time and again to overcome problems that seemed virtually insurmountable. This book provides comprehensive approach for basic way of thinking, scientific mechanism for improvement, problem identification and implementation. The book is a good combination of distinctly industrial engineering and non engineering presentation that holds and inspires the imagination of a non-technical person.

Manual chucks The production capacity of a lathe is entirely a function of the chuck used, the gripping power and the true running of the chuck. Guindy Machine Tools offers manual chucks. The chuck body and the wormwheel-cum-camring are made from steel forgings, which provide the desired grain flow and this minimise distortion under the clamping forces. All parts are amply proportional, made from high-tensile alloy steels, hardened and ground wherever necessary, to close limits of accuracy. The normal dimensional variation in the gripping diameter of jobs is taken care of by the adequate stroke of the base jaws, thus avoiding frequent resetting of the false jaws. On each circular cam, slides a chrome case-hardened button with a groove of the same radius as the cam. This provides a large pressure bearing area to the load transmitting surfaces. The large bearing surfaces reduce the stress per unit area to the minimum and completely inhibit any denting of the circular cam.
