A Computer Aided System to Design Process Sequences for Deep Drawing Round Parts 950919

Designing the process sequence for deep drawing round cups is a trial and error process. The variations in the part geometry and processing conditions lead to a variety of problems that have to be solved after the dies and punches have been made. A system to design processes sequences is being developed at the Engineering Research Center for Net Shape Manufacturing (ERC/NSM). The system would help designers in developing the sequences, evaluating these sequences, and in predicting possible problems before production of parts. This would lead to a substantial savings in time and money. This system has three modules, a design module to design the process sequences, a finite element analysis module to simulate the forming process to predict possible problems when forming the part, and an interface module to handle data transfer between the two modules. The design module of the system is documented here.
