The FABTECH logo may be new, but the results of FABTECH 2017 reflected the continuing commitment to advancing the technology of the forming, fabricating, welding, and finishing industries that the five sponsoring industries represent. “The manufacturing industry is entering a new age and experiencing an industrial revolution that is changing the way we manufacture,” said John Catalano, FABTECH show co-manager and SME senior director. “And in the midst of this, FABTECH is also evolving to stay at the leading edge of the industry. We are excited to launch a new logo that demonstrates the evolution of the FABTECH brand.”
“While we usher in a new visual identity, FABTECH remains committed to delivering a high-quality, innovative event experience,” added Mark Hoper, FABTECH show co-manager and FMA senior vice president of media and expositions. “The show will continue to meet the demands of the industry and showcase not only what’s new, but what’s next.”
And what’s next may already be here. Advances in manufacturing technology of all kinds—from hardware to software and productivity-enhancing ancillary equipment—could be seen in the booths of 1700 exhibitors who took up 750,000 square feet of exhibit space. They welcomed 45,000 plus visitors to Chicago’s McCormick Place, where FABTECH 2017 revealed that the metal forming and fabricating industry is well aware of the key trends in the metalworking industry. Automation, digitalization via Industry 4.0, and just about any way of lasing, punching, cutting, burning, and welding materials were highlighted in virtually every exhibit.
Targeting the Skills Gap
Panels of industry experts probed the key trends in metalworking manufacturing with well-attended discussions about the state of manufacturing, the potential of hybrid additive manufacturing, and innovative workforce development efforts to fill the skills gap in manufacturing. There are many more jobs—several million by various counts—that are going unfilled in manufacturing because there aren’t enough qualified candidates. STEM training of the young is the job of manufacturing companies, one prescient panelist said, especially since companies haven’t been as committed to doing the job in the past.
Panelists agreed that the time for action by manufacturers is now to fill the growing skills gap between the metalworking jobs available and the pool of qualified candidates to fill them. In assessing the state of the industry, panelists pointed out the apparent disconnect between the high-tech reality of today’s manufacturing shops and the “smokestack” image of the past. Young people who attended FABTECH 2017 were able to see the truth of modern manufacturing. Panelists agreed that the next most important step is to communicate that to their parents and the schools at the earliest grade levels as possible.
At the 3D/Additive Pavilion, a panel of experts examined the implications of this hottest of technologies. The panel, “Evolution of Additive Manufacturing and What It Means for the Fabrication Industry,” revealed the challenges in design, implementation, and—for this audience—the metallurgy behind the growth of AM.
“Additive manufacturing is an enabler—you can use it to make end-use products, tooling, or prototypes. It is now an alternative manufacturing process,” said Carl Dekker, president of Met-L-Flo Inc. (Sugar Grove, IL), a contract manufacturer utilizing AM. “It enables the evolution of technologies or products that would not be economically viable to go to production any other way, and gives them a chance to see the light of day. As those types of products proliferate, we will see more opportunities that we can’t even comprehend now.”
Dekker outlined how the technology has evolved. “We all called it rapid prototyping until we realized that we could make parts with it. If you are producing an object for final use, whether that use a jig, fixture, or a part, that is manufacturing,” he said.
Jon Riley, senior vice president, technology for the National Center for Manufacturing Sciences (Ann Arbor, MI) pointed out that additive manufacturing of metal parts can be very cost effective, and companies are making them now. However, the extremely wide range of materials available to design parts makes using AM a huge unknown—especially for aerospace. “Airbus, Boeing, and GE all have the money to test and qualify additive processes, which involves making lots of metal parts,” said Riley. “It’s difficult for small companies to invest that kind of time and money to get data sets for the aerospace part approval process.”
He said a big step forward would be developing more information on metal additive materials through the technical committee process to make metal AM a more viable process for small to midsize companies.
Attendees couldn’t escape how “Smart” with a capital S has taken over the discussion of connectivity from the shop floor to management to remotely located suppliers. Major machine builders demonstrated how processes can be monitored, orders tracked, and data collected and analyzed on a real-time basis. And advances in automation are needed to keep up with the blazing speeds today’s fiber lasers are capable of.
In a process you might call “Part to Art,” collaborators Albert Paley, renowned sculpture artist, and Jesse James, famed West Coast Chopper personality, used their talents to create two metal sculptures, each of which resembles a collage of metal parts. In a collaborative process, Paley and James each began creating one of the sculptures, then traded the sculptures, each of which was finished by the other artist. The sculptures will be auctioned by Wright Auction House in Chicago, with proceeds benefiting the five FABTECH co-sponsors—AWS, FMA, SME, PMA, and CCAI—in order to support grants and educational opportunities for the metalworking trades.
News from the Exhibit Floor
The forming and fabricating industry has never been short of precision engineered equipment, but the addition of smart communications for individual machines, machine networks with centralized data collection, and data monitoring for maintenance and troubleshooting has taken equipment to the next level. Plus, advances in conventional manufacturing technology continue to make manufacturers more productive.
Amada America Inc. held a press event that focused on both smart communications and traditional manufacturing technology. The company demonstrated new laser operations via a live video stream from its Schaumburg, IL, technology center to the Amada booth.
