Abstract：

For the wave spring sheet of clutch, the parameters in stamping process were optimized based on response surface method. Then, the response value of forming height was obtained by central composite design and bending die, and a secondorder response surface model between process parameters and forming height was established. The results show that the sequence of interactive influence of stamping process parameters on forming height is bending radius and stamping speed, die clearance and stamping speed, bending radius and die clearance. In addition, the die clearance, bending radius and stamping speed are taken as design variables, the forming height is taken as optimization objective, and response surface model is optimized by Design Expert software. Therefore, the optimized parameters of stamping process with bending radius 22.13 mm, die clearance 1.01t mm，stamping speed 2699.47 mm·s-1 and response value of forming height 1.782 mm are obtained by analysis. Furthermore, the experimental value forming height is 1.72 mm by rectification of process parameters. However,the response surface method has the greatest advantage in optimization of stamping process parameters compared with the optimized value 1.65 mm by orthogonal experiment.
