Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."

Beware predictions of the demise of any technology. If the early 1920s saw the dawn of the optical comparator, there has been much speculation about its sunset. That was especially true when vision systems started hitting their stride a few years ago. Many could see optical comparators were superfluous with the use of vision systems. Many thought the sunset of optical comparators was imminent. Many were wrong. Why?

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.

Starting this month, TechFront has a new format that spotlights manufacturing research programs at key universities, followed by summaries of recent research in SME’s Journal of Manufacturing Systems, Journal of Manufacturing Processes and Manufacturing Letters, all published by Elsevier Ltd.

Four universities—Iowa State University, University of Minnesota, University of Wisconsin-Madison and North Dakota State University (NDSU)—competed in the inaugural 3M Industrial Adhesives and Tapes Disruptive Design Challenge (DDC) at 3M’s headquarters (St. Paul, MN), Friday, April 13.

Looking to reduce costs, save time and enhance your design options? Take inspiration from real examples of manufacturer’s who have achieved all these and more.

Machining aerospace materials is a challenging task. Not only are machining operations tightly controlled, a wide variety of workpiece materials are employed, including aluminum, titanium, and carbon-fiber reinforced plastics (CFRPs). The following is a brief guide to cutting tool options for successful machining of airframe components. All of the tools referenced are manufactured by Mitsubishi Materials.

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.

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.

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).
