Strategies for springback compensation (C03)

• Subject Area: Materials Engineering
• Term: from 2007 to 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 16071898

Springback-induced target-geometry deviations commonly occur in the production of deep drawn sheet-metal parts. For an optimal and robust layout of the process, methods from the fields of sheet metal forming and statistics are employed. After the successful study of the influence of time-varying parameters, spatial distributions on the tool surface are investigated next. In addition to studying cold forming, the press hardening process will be examined. The aim is an optimal accuracy in terms of geometry and form exactness over the formed sheet metal so that the formed parts can be utilized without major post-processing.
