An Austrian specialty metals’ producer- Bohler Edelstahl - is now operating the world’s largest radial forging machine. The RF100 from American GFM features a maximum forging force of 2000 metric tons. Forging with varying stroke frequencies and rotation angles can create a well-worked core structure as well as improved surface quality. One of the reported benefits is improved microstructure, an important feature for critical aerospace and oilfield applications. One goal is to produce large round bars and billets of nickel alloy 718, 625 and Waspaloy. Bohler Edelstahl, which dates to 1860, focuses on production of high speed steels, tool steels and special materials, concentrating on highly demanding applications. The new generation radial forging machines type RF from GFM combine the technologies of a mechanical eccentric press with that of a hydraulic press.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
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.
