Abstract：

Improving the material utilization of automotive body metal panels can significantly reduce the cost of parts，and enhance the product competitiveness. A method for improving the material utilization rate of automotive body metal panels was introduced so as to achieve the purpose of cost control. With the help of CAE in the early stage of sheet metal forming, the part optimized state and process scheme were obtained by the partboundary adjustment, the craft surface optimization, the automatic nesting technology in the software and the knowledge accumulated in the actual production process. Thus, the material utilization was up to the maximum. For the rear wheel arc plate parts of a car, the material utilization is reduced from the initial 40.2% to 49.8%, so the material per vehicle saves 0.11 kg, and the material costs saves 0.7 yuan after the above method is adopted. Furthermore, the above method is effective and feasible.
