| Abstract: | Numerical simulation of the blanking process of sheet metals is done using arigid plastic finite element code and commercial software by the authors,analyzing the mechanism of burr formation process in blanking. To study the effect of the interaction between clearance and circular radius of punch, a series of Simulation have been carried out with different value. Compared with present experiments results,the finite element simulation results show good agreement with it.By the simulation results,we can predi... |
