Abstract In order to study the material removal mechanism and micro chip formation process of 20CrMo, Johnson-Cook mo-del was used as constitutive model of 20CrMo material, 3D FEM simulation model of micro chip formation process was set up based on single CBN grain grinding of 20CrMo in Abaqus. Effects of grinding parameters on micro chip formation process were discussed. Simulation results show that grinding velocity exerts more affects on plough and chip formation stage, and effect of grinding depth on sliding and hip formation stage is obvious. Experiment of single grain grinding was set up, and micro chip formation process was experimentally studied and analyzed. From the view of grinding groove characteristics and micro chip shape, experimental results agree well with the simulation results, therefore, 3D FEM simulation model of micro chip formation process is experimentally verified.

Key words： single abrasive grain 20CrMo chip formation process grinding finite element simulation
