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.
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.
Coolant is a key component to successful centerless grinding but is often overlooked. Many coolant delivery systems for centerless grinders are under engineered and are often neglected.
In what shouldn’t be too much of a surprise, challenges for advanced grinding technology from high tech industries range from handling the most difficult-to-machine materials for aerospace jet engine turbines to series production on automotive drive train lines.
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.
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.
Manufacturers are always looking for ways to keep ahead of the competition. And with advancements in bonding technologies, they’ve been able to explore new ways in doing just that. Industrial-grade, double-sided acrylic foam tapes such as 3M™ VHB™ Tapes are increasingly being used in place of more traditional mechanical fasteners such as screws, rivets, bolts, and welds—in order to permanently bond components together.
