Abstract

This study is aimed to predict the minimum varying blank holder force (VBHF) during the punch stroke, in order to eliminate wrinkle on cup deep drawing product. The slab method was used to develop mathematical modeling of the minimum VBHF base on a gap limit and unbending energy. The mathematical modeling has been validated to FE simulations for the prevention of wrinkling in the same criterion. Steel sheet of SPCD grade with thickness of 0.2 mm is used to generate the cylindrical cup shaped product with 40 mm diameter. Analytical Results of minimum VBHF have a similar trend result compared to FE simulation. However, the minimum VBHF can be quite effective for preventing the occurrence of excessive wrinkle
