Taking the parts of car bracket forming process as an example, the issues of difficult removing for waste material during side punching and short die life for the forming process of “first blanking punching, and then bending technology” for the parts with special shape and structure were studied . The deformation effect on the quality of formed part of the blank with holes in forming process was analyzed to ensure that the shape and size of the formed part could meet the drawing requirements . Using the FastForm software of finite element analysis based on CAE (Computer Aided Engineering) for sheet metal forming,and according to the numberical model of formed part and forming material properties,the sheet blank with holes for being formed parts was reversely flattened and delivered.  The sheet blank edge-shape and hole size generated by the numerical simulation were taken as the designing references for the punch and die edge and hole shape design .Therefore,the mold design cycle can be shortened to reduce the production costs and improve the product quality and market competitiveness of enterprise.
