Die tryout prior to starting serial production plays a significant role in stamping automotive components. Despite advancements in FE simulation as a virtual process to predict material flow and correct tool designs, die tryout still requires a significant amount of time. This could be attributed to the assumptions / simplifications of the FE models used for simulations where significant press and cushion characteristics are neglected. In this study, FE simulation of the die tryout process was conducted along with experiments to analyze the influence of various factors of the multipoint cushion system in a single action press in forming a large auto body panel. The multipoint cushion system in the press was programmed using FE simulation as an alternative to conventional spotting done in several tryouts. Thus, an alternative has been developed for reducing time and cost by implementing the use of multipoint cushion systems in serial production.
