摘要：Simulation of Micro Blanking Process of Square Hole with Fillet was carried out based on DEFORM-3D. The ratio of burnish depth, shear depth and fracture depth to sheet thickness under different relative blanking clearance (c/t) was analyzed. The results show that the burnish depth at the fillet increases generally with the increasing blanking clearance, while the burnish depth at the straight-line segment firstly increases and then decreases with the increasing blanking clearance. The relationship between burr height and relative blanking clearances (c/t) was discussed. Results show that the average burr height increases with the increasing blanking clearance.
