Abstract：

For stamping part, simulation test of blanking was designed based on response surface method. Then, the blanking process of sheet metal was simulated by DEFORM-2D, and a mathematical model between blanking parameters and the length of bright region for blanking were established. The analysis of simulation results shows that blanking clearances and fillet radius of die have the greatest interactive effect on the length of bright region. Therefore, blanking speed, blanking clearance and fillet radius of die were taken as design variables, length of shear zone was taken as optimized objective, the response surface model was optimized by software of Design Expert. The optimized parameters of blanking are obtained with blanking speed 14.04 mm·s-1, blanking clearance 8.99%t mm and fillet radius of die 1.25%t mm (t is sheet thickness), and response value of length for bright region 0.834 mm. In addition, the experimental verification was conducted by stamping die, and the relative error between experimental value and response value is 11.8%. Therefore, the accuracy of response surface method applied in the optimization of process parameters for blanking is verified.
