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.
A new process for laser-welding large-scale, steel-aluminum foam sandwich structures for lightweighting ships, which eliminates intermetallic phase, has been demonstrated.
A major advance in repairing composite structures combining robots and lasers bodes well for commercial aircraft such as the Boeing 787 Dreamliner and Airbus A350XWB, which contain composites in large proportions of their structures.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
