Knowledge-based stamping direction optimization for auto-body panel workpiece

This paper developed a module system which can automatically determine the stamping direction of the sheet metal part in UG system based on the three-dimensional digital model of the product. According to the knowledge and expertise of mould design the principle of the stamping direction is determined and thus the fundamental mathematical model is established. Using advanced optimization algorithms and programming techniques to process of the mathematical model, and performing a comprehensive analysis for the solving results, the feasible region of the stamping direction is found, and thus can in the feasible region to establish an optimal stamping direction. The use of secondary development technology to develop the software module with the similar UG software user interface, easy operation, to achieve the automation of the stamping direction determination, can improve the efficiency and quality of mold design significantly.
