Process Parameter Design in Sheet Stamping Processes with Rigid-plastic Finite Element Analysis

Abstract

Determination of the effect of the process parameters on the final forming quality is very difficult in sheet metal forming process because forming processes experience very complicated deformation. These process parameters have to be determined for the optimum forming condition before the process design. In this study, finite element program is developed for analyzing the deformation in sheet metal forming operation. Design optimization concept is introduced to calculate the process parameters such as the bead force within the given design requirement. The effectiveness of this theory is examined by solving the deep drawing processes.
