Abstract：The finite element method is introduced to simulate the process of fine blanking,then the simulation result to analyze the influence of the fine blanking process parametres on the quality of fine blanking forming parts. Firstly,the basic principle and the mechanical properties of fine blanking process are analyzed. Secondly,the finite element mesh mechanics model is set up for the thick stainless steel flange of the automobile exhaust system by combining the key technologies of fine blanking process,and using the abaqus finite element analysis software. Finally,the mean values of hydrostatic stress in 10 steps of the whole fine blanking process are extracted and calculated after the whole process of fine blanking is simulated to evaluate the influence of different parameters. The die clearance of fine blanking process is considered to be a variable. When the die clearance is 0.3mm,the quality is better.
