A machined groove for the O-ring that doesn't break or flare out when tightened makes the new Anver Captured O-Ring Barbed Fitting (www.anver.com) vibration proof, says the company. Engineers there say it provides a leak-proof, tight fitting seal and retains its position. The component is designed to screw into suspensions and provide the fit of a metal-to-metal connection with the static sealing qualities of an O-ring. The grooved design reportedly simplifies installation by eliminating the need for replacement gaskets or washers because the seal is already properly positioned for a tight fit.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
