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.

Cutting Tools for Composites

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 Technologies Supplement: Processes Reduce Composite Costs

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).

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.

Buck Rogers Blasts into the Toolroom

In addition to carbide, ceramics, and cermet, the drive to create the hardest possible cutting tool materials has given us the alphabet soup of PCD, PCBN, CVD-D, and MCD (polycrystalline diamond, polycrystalline cubic boron nitride, chemical vapor deposition diamond, and mono-crystalline diamond, respectively).

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.

Additive Grows and Has Growing Pains

Additive manufacturing is both growing and coping with growing pains. Companies “have to find ways to streamline” polishing and other finishing processes of 3D printed parts, industry consultant Terry Wohlers said today during a speech at RAPID + TCT.

Coatings Expand Cutting Tool Capabilities, Reach New Markets

When first introduced in the late 1970s, cutting tool coatings—especially titanium nitride (TiN)—were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.
