Abstract：

The nonstandard wedge aided design system of automobile panel die was developed base on the CATIA CAA secondary development technology. In the system, the replacement process was optimized by the judging method along the closed surface direction of bounding box and along the plane direction of reference coordinate system to ensure the validity of replacement. Then, the design method of nonstandard wedge part was optimized by standard part design method based on the position sketch to realize quick adjustment of the standard part number and position. Furthermore, combining parameterization template of CATIA with years of design experience and design standard from enterprises, they were integrated to guarantee the consistency and rationality of the nonstandard wedge design. According to the practical statistics from enterprises, the efficiency of nonstandard wedge design was increased by about 50%.
