Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.
When GE decided that additive manufacturing was the way to go for making metal fuel nozzles for its new LEAP engine, the company touched off interest in other shops to move 3D printers from the design studio to the factory floor. It also stepped up the focus on safety standards for metal AM.
New coatings are going the boutique route, using multiple layers and new materials to optimize for a particular application
Supplying the 700 level-one trauma centers in the US is an intensively competitive business. Not only must suppliers like Smith & Nephew Orthopedics Inc. (Memphis, TN) produce very fine surface finishes on implantable devices and surgical instruments made from difficult-to-machine materials, but they also must deliver quality products, as surgeons need them.
The landscape is changing and one estimate says all new passenger cars sold in Europe will be electric or hybrid by 2025. For the companies supplying the global automotive market, this fact and others will require an immediate and ongoing assessment of technologies and machinery.
Moldmaking is making a comeback, with more reshoring to North America of mold-and-die manufacturing that left for the Far East and other low-cost manufacturing centers. With faster metalcutting through high-speed machining (HSM) and improved EDM techniques, mold-and-die shops are finding innovative ways to compete with manufacturing operations in traditionally low-cost labor markets.
A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
Investing in factory automation for the first time is a big decision for many CNC machine shops. For Loveridge Machine (Salt Lake City, UT), owner Dennis Loveridge thoroughly researched his options before making a decision for his high tech job shop.
