This paper describes the stamping CAE system which has been developed to rationalize the processes of stamping die design, manufacture, tryout and modification, where the most man-hours and lead time were required in the development and production preparation of a car body. This system is characterized by capabilities not only to allow interactive and efficient design but also to transmit the design information which canbe sufficiently evaluated on the same graphic terminal in terms of press forming severity, to the subsequent process. This system constitutes an important part of the integrated body CAD/CAM/CAE system. The evaluation method employed in this system is used by some Japanese car manufacturers as a common methodology. The changeover from the art to the scienceis expected to be prompted by refinement based on further research and development on simulating sheet metal forming and highly intelligent CAE.
