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.
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.
The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.
Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.
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.
