Systematic Process Improvement of Stamping Processes

Abstract:

The design of a suitable forming process for a stamped part is a complex issue. Many boundary conditions must be fulfilled and many considerations must be made to come to a successful solution. Elimination of wrinkles and splits very often need contrary counter-measures and, more often than not, it is both an iterative and subjective process. AutoForm Engineering has thus developed a methodology whereby stamping issues are automatically detected, based on all important failure and quality criteria, and which enables automatic tracking of engineering progress. This paper introduces a systematic approach which reduces the number of loops in the effective design of a forming process and allows the streamlined evaluation of multiple simulations in order to determine the most influential parameters to generate the best solution. The automatic detection of stamping issues and subsequent systematic process improvement will be illustrated using both an academic part and a real automotive component.
