Tooling to Match Composite Production

It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”

Solutions for Difficult Machining

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.

Lasers on the Cutting Edge

In the last seven to eight years, solid-state lasers have come to dominate laser welding and cutting,” said Tom Bailey, product specialist for Trumpf Inc. (Farmington, CT). While Trumpf still produces CO2 lasers, for most applications solid-state lasers literally outshine them.

2016 Was a Good Year for Lasers; 2017 Looks Even Better

Strong 2016 earnings among top industrial laser providers, continued brisk adoption of fiber lasers, cheaper ultrafast lasers, and a host of novel applications and notable corporate acquisitions signal a big year ahead for photonics-based manufacturing.

Advances in Titanium Machining—Do More on Less Floor

The demand for titanium components by the aerospace industry began as a whisper about 15 years ago and steadily grew to a sustained, raucous shout over the last five and likely won’t quiet for several more.

Hard Hips

The challenge of machining hip replacement implants out of cobalt chrome

Extrusion and Drawing Knowledge

Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.

Keeping Old Planes in the Air with Laser Scanning

Your father’s Oldsmobile may be long gone but his B-52 is still pulling missions, and they haven’t built the “BUFF” (Big Ugly Fat Fellow) since 1962. The last KC-135 tanker was built in 1965. Besides aging warbirds (the average plane in the US Air Force is over 28 years old) there are hundreds of ancient civilian airliners carrying friendlier payloads everyday. The key to doing this safely is of course excellent maintenance and periodic upgrades. Laser scanning plays an essential role.

Cold Sintering Process Saves Energy, Material

Researchers at Penn State University (University Park, PA) have devised a novel method for sintering, a widely used manufacturing process for powdered materials. The new process, which uses much less time and energy than current approaches, could have global implications on manufacturing and energy savings and pave the way for new discoveries.
