Abstract

In the automobile development, press tool design and manufacturing are very difficult and need high cost experienced workers. Therefore, we concerned ourselves in the cost down and easy manufacturing. In this research, we have developed a tool for LH/RH of the front fender, which had difficulty in forming. We have carried out the drawing analysis by Pam-stamp and CATIA modeling. Finally, we get the optimal design parameter. As a result of try out, we found out the optimal width and margin at the center line for tool design. Also, in order to get good results we have to intaglio margin in the part of the wheel house and utilize double bead on every side except corner.
