The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.

Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix.

Advanced materials for automotive manufacturing are helping automakers build lighter, more fuel-efficient vehicles.

Composites engineers are expanding their craft to build more complex, durable parts at higher production volumes. One way they are achieving this objective is by using infusion-molding processes based on Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM).

As in other industries, U.S. forming and fabricating companies are experiencing a critical shortage of skilled labor. In this SME Media podcast, Alan Rooks, Editor in Chief of Manufacturing Engineering magazine, talks with Robert Tessier, National Director of Advanced Fabrication Technologies for Airgas about the skills gap in the forming and fabricating industry; changes needed in the education system to fill the need for skilled labor; how automation factors into efforts to reduce the skills gap; and efforts at Airgas to develop workers for manufacturing operations, including a special program for military veterans.

The need to permanently laser mark parts for tracking and tracing continues to grow.

Smart manufacturing is transforming A&D manufacturing as more companies adopt automation, artificial intelligence and robotics. Some manufacturers are also focusing on eliminating so-called islands of automation and integrating the technology across entire processes.

The three keynote speakers of HOUSTEX, EASTEC, SOUTHTEC and WESTEC—the Manufacturing Technology Series—offer perspectives pertinent to manufacturers in general, but of particular use to small and medium-sized manufacturers.

Around the U.S., the major manufacturing regions are taking stock of the fallout from the pandemic and how they can navigate out of the lockdowns in 2020 to thrive once again.

Among the expected new product offerings a company such as Trumpf would offer at FABTECH, it chose to show all of its offerings via large video screens and real-time links. It shows the reality of not only Industry 4.0 but Marketing 4.0 as well.
