Compumotor has developed a direct drive rotary servo system that's the most compact in the company's Dynaserv line. Each consists of a brushless servo motor with 10-ft of motor and encoder cables, microprocessor-based drive, power supply, and an incremental encoder. Offered in both 4-inch and 6-inch diameter versions, they are available in speeds up to 2.5 rps and resolutions up to 655,360 positions per revolution. Axial and radial runout measures 10 mm--10 times better than the Dynaserv DR and DM series--with 5 mm available. Applications include scanning, semiconductor processing, disk drive assembly, rotary indexing, industrial robots, and low-speed inspection. Parker Hannifin, Compumotor Division, Product Code 4173.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
