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?

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.

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.

Lasers — well-established tools in the manufacture of medical devices—are continuing to break ground by producing smaller, more precise and more functional parts thanks to faster pulse speeds at lower cost, new applications and the marriage of laser processing to Swiss-style machining.

Data mining and Big Data are hot topics. Your company develops process mining software; how does it differ from data mining?

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.

When Desktop Metal introduced its “office-friendly” Studio metal prototype printer earlier this year, the company renewed attention on the issue of safer materials for binder jetting, an additive manufacturing method.

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.

Like its products, technology demands for thyssenkrupp Elevator Corp. are “going up.” A business unit of ThyssenKrupp Elevator AG, the company oversees all business operations in the US, Canada, and Central and South America, and says it is the largest producer of elevators in the Americas, with 13,500 employees, more than 200 branches and service locations, and sales of $2.7 billion.

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.
