Advanced Manufacturing Now

Smart manufacturing, Industry 4.0, and the Industrial Internet of Things are all fast-evolving concepts that are changing how manufacturing processes are designed and implemented. In this podcast, Alan Rooks, Editor in Chief of Manufacturing Engineering magazine, talks with Ben Mund, Senior Market Analyst for CNC Software Inc., the developer of Mastercam CAD/CAM Software, about how companies are addressing these changes, including how parts are designed, programmed and manufactured. The discussion includes changes to toolpath development, evolution in manufacturing methods, and how manufacturers are dealing with growing "skills gap" in the manufacturing workforce.

Pete Rogers, a vice president of Acieta, discusses an impending "welding labor crisis" of a shortage of skilled welders. He talks about automated welding systems can take the load of repetitive welding tasks.

Duann Scott of Autodesk discusses developments in software for additive manufacturing. He talks about simulation and design for 3D printing with Bill Koenig, a senior editor of Manufacturing Engineering. This podcast was recorded at the RAPID + TCT in Fort Worth, TX, in April.

Sean Touhey, a junior in the manufacturing engineering program at Western Washington University, describes the innovation that led to his 5-person team winning the "design for digital manufacturing" competition for university students at RAPID + TCT. His team focused on eliminating leftover residue (sticky stuff on the dashboard), visual obstruction and airflow obstruction for cell phone mounts.

At the RAPID + TCT conference in Texas, Brian McLean, director of rapid prototype at Laika Entertainment, explains what led to his being awarded a Scientific and Engineering Oscar Plaque in 2016 for pioneering the use of 3D printers in stop-motion animated characters. He goes into the ways AM can be a competitive advantage, including precision, color accuracy, volume and repeatability. And he compares what he does with puppets to what manufacturers are doing in the medical field.

Dr. Mike Grieves, executive director of the Center for Advanced Manufacturing and Innovative Design at Florida Institute of Technology, explains ITEAM (Independent Technical Evaluation of Additive Manufacturing), which was recently introduced at RAPID + TCT. ITEAM is, he said, "a user-driven consortium to help advance AM faster than what is happening right now." The focus is on creating an information ecosystem that lets users answer "two core questions they always have to answer when they are looking at new technologies:" Can I build it with AM? (Is it technically possible?) And should I build it with AM. (Is it economically feasible?). GM, Infosys and SME are already involved.

At RAPID + TCT, Bruno Boutantin of Extrude Hone and Laurent Cataldo of Binc Industries speak about their firms' new joint offering: Finish 3D, for AM. It is, Cataldo said, "a full solution for the global market, for medium- and high-volume production series." It combines Binc's MMP (micro machining process) technology—a physical, mechanical and catalyst process "usually used to very low roughness levels"—with Extrude Hone technology for additive parts when they require finishing processes like AFM (abrasive flow machine) and CoolPulse. Finish 3D can be used in any market, he said: In addition to aerospace, "we do medical implants, and we can be used for tooling, for plastic injection mold, whatever, as soon as the volume can absorb the cost of the preparation and the fixture." Boutantin said the new offering lets customers for the first time "take any incoming roughness and … bring it below the micron." Getting to the sub-micron level is important in aerospace, for example, when manufacturers need to improve airflow in jet engine turbines, he added.

At the RAPID + TCT show in Texas, Chris Schuppe, GM of AddWorks at GE Additive, explains a new offering called AddWorks. He gets into how it came about, what it is, why it is needed, and what types of services GE is offering with it. Listeners who are already in AM can still benefit from AddWorks, said Schuppe, who details what automotive and medical customers have accomplished with AddWorks. "We've had challenges where we couldn't figure out the next steps in our (AM) journey," he said. "We lived that over the last 7-10 years. Now we are taking that as an external consulting service."

Roger Hart, research and development engineering manager of Siemens, talks to Senior Editor Bill Koenig about additive manufacturing at the RAPID + TCT Show in Fort Worth, TX. They discuss how Siemens is changing its strategy to use 3D printing. The company is moving to transition from rapid prototyping to "true manufacturing," according to the executive. Hart also talks about Industry 4.0 and other advanced manufacturing issues.

Bhuvi Nirudhoddi, an Ohio State University PhD candidate studying materials science and engineering, won the student poster challenge at SME's AeroDef manufacturing conference in California in March. She gives Advanced Manufacturing Now the 411 on her work—"Joining of aerospace alloys using high-speed impact welding"—and explains how she came up with the concept, as well as where she thinks it can make the biggest impact?
