Abstract：

For F0 type spinning traveler sheet with the thickness of 0.44 mm, the stamping process under different parameters, such as cutting clearance, punching speed and cutting edge radius, was simulated by software Deform-3D, and the whole process of sheet metal fracture was analyzed. Then, taking the burr length generated after sheet metal fracture as the evaluation standard of section quality, and the optimal process parameters combination were selected by the analysis method combining with numerical simulation and orthogonal experimental design. The simulation results show that the burr length is smallest under the optimal parameters with the cutting clearance of 8%t, the cutting edge radius of 1.5%t and the punching speed of 5 mm·s-1. In addition, the experimental verification was conducted by the new type traveler forming machine, and the experiment value of burr length is 0.0186 mm, which is 0.017 mm for the simulated optimal value, the error is about 9.41%, but the average burr length is reduced by about 7%. Thus, the optimal process parameters combination obtained by finite element simulation can effectively reduce the burr length is proved.
