Peter Zelinski has been a writer and editor for Modern Machine Shop for more than a decade. One of the aspects of this work that he enjoys the most is visiting machining facilities to learn about the manufacturing technology, systems and strategies they have adopted, and the successes they’ve realized as a result. Pete earned his degree in mechanical engineering from the University of Cincinnati, and he first learned about machining by running and programming machine tools in a metalworking laboratory within GE Aircraft Engines.

EOS North American User Day Comes to IMTS

This batch of parts produced through direct metal laser sintering
was made by one example of an EOS user, C&A Tool.

At next month’s International Manufacturing Technology Show, various new developments reflect IMTS attendees’ heightened interest in additive manufacturing and the sizable number of exhibitors offering additive manufacturing services or technology. This category has now added its name to a pavilion: This year the North Hall will house the Fabricating/Laser/Additive Pavilion. In addition, a new event has been added to the show: the half-day Additive Manufacturing Workshop September 9.

One other significant additive manufacturing development is this: EOS, the maker of additive manufacturing machines for metal and plastic parts, has for the first time brought its North American User Day to IMTS. The recurring event that gathers together users of EOS laser-sintering technology will take place Wednesday, September 10, and is open to both EOS customers and IMTS attendees. Speakers will include Dr. Hans Langer, the company’s founder and CEO, as well as companies offering solutions related to additive manufacturing such as MicroTek Finishing, Shapeways and Within. To register or learn more about either the EOS North American User Day or the Additive Manufacturing Workshop, visit this page.

Video: Young People and Their Mentors Describe Manufacturing Careers

Loading the player ...

Cutting tool supplier Widia and manufacturing media firm Creative Technology produced this video titled “Why Not Me?” to illustrate manufacturing careers, and to highlight young people who have chosen this work as well as their employers and teachers. The video visits various sites where manufacturing is either performed or taught, including Cardinal Manufacturing, Chippewa Valley Technical College, MRS Machining and Prototype Solutions Group. Carlos Cardoso, chairman, president and CEO of Kennametal Inc. - Widia Product Group, appears in the video to make the case for the value and opportunity of manufacturing careers.

Video: Racing Engine Oil Pump Gear Produced through Additive Manufacturing

Gears are expensive parts to make in small quantities. This video from 3D Systems describes how just one gear—for an oil pump—was critical to overcoming a problem with excessive oil pressure in a Mitsubishi 4G63 race engine for a car run at over 185 mph.

English Racing of Camas, Washington, knew that a change in gear size might solve the problem, but the team didn’t know how to get this gear. The complex custom part would have been costly to machine as a one-off job, particularly since one-off prototypes would also be needed to test and refine the design.

Metal Technology of Albany, Oregon, proposed additive manufacturing instead, growing the part directly from the CAD model on its ProX 300 direct metal sintering machine. This video shows the part not only being additively manufactured in this way, but also functioning successfully at full speed within the engine.

Why Reshore?

Kent Bicycles, a United States-based company that currently manufactures bikes in China, will be building a plant in South Carolina so that it can serve American demand with American production. This Washington Post article details the company’s move. The article paints an interesting picture of reshoring, identifying the many factors that contributed to the move. According to Kent CEO Arnold Kamler, the reasons for reshoring include all of the following:

1. Shifting Opinion. In the 1990s, he says, offshoring was fashionable. “Made in the USA” was not. For a manufacturer to be regarded well by important commercial partners (retailers, for example), it helped to look to offshore production even for small cost savings.

2. Customer Encouragement. Related to Point 1, Wal-Mart recently expressed its new preference to Kent. The big retailer enouraged the bike maker to shift some production to the United States. Wal-Mart’s encouragement gave Kent the confidence to press ahead.

3. Foreign Demand. International business is doing so well that Kent expects to be able to sell all of its current overseas production outside the United States. Therefore, this shift in production will not subtract production from overseas. Instead, U.S. production is the alternative to an overseas increase.

4. Cost. Cost of labor in China is increasing. The difference between U.S. and Chinese labor cost is not as great as it once was.

5. Worker Commitment. Mr. Kamler found what he regards as a serious attitude toward production-floor work in Clarendon, South Carolina. Many of the workers he observed were single mothers basing their families’ livelihoods on this work. By contrast, he has noted what he views as an increasingly “apathetic” attitude among personnel in overseas facilities. He cites the distraction of cell phone use by production employees as a significant problem.

6. State Competition. State governments recognize the value of manufacturing and are pursuing manufacturing facilities. New Jersey and South Carolina competed for Kent’s plant. Part of the winning offer from South Carolina was the commitment to train Kent’s workers for free.

New This Year: IMTS Virtual Field Trip for Students

Loading the player ...

Students who are too far from Chicago to be able to visit the International Manufacturing Technology Show in person will be able to experience IMTS in their classrooms thanks to “Technology Applied,” a new, online virtual field trip that will be filmed at the show. Teachers can register to access any or all of the show’s three 30-minute episodes, which will be broadcast on three consecutive days during the IMTS: September 10, 11 and 12.

The virtual field trip will be filmed, produced and hosted by the team that creates The Edge Factor Show. By taking an exciting look at some of the automation, equipment and processes demonstrated at IMTS, the episodes show students the technology they are likely to employ if they pursue manufacturing careers, and will also illustrate how science and mathematics are applied in manufacturing every day. CNC machining, additive manufacturing, aerospace manufacturing and racecar technology are some of the topics to be addressed, with content appropriate to grades 5-12. Learn more by watching the teaser above and by visiting the “Technology Applied” registration page.

Consider encouraging the teachers you know to register for this event. Thanks to the support of Sandvik Coromant, the lead organizer of the virtual field trip, registration is free for the first 1,000 teachers who sign up. Learn more.
