Numerical Simulation and Parameter Optimization of Cam’s Fine Blanking Process

To conclude the mechanics of fine blanking, the numerical simulation model of a cam’s fine blanking process was established, the forming process was simulated by DEFORM-3D software, the deform principle was summarized. Then the effect of three key processing parameters such as gap between punch and die, pressure-pad-force/counter force, serrated ring postion to fine blanking quality were researched, optimized parameters in fine blanking were gained.
