Abstract:Based on the ABAQUS simulation theory，the material constitutive model， friction model and fracture criterion are established respectively.The local mesh refinement is used to make thesimulation result more accurate.Besides，the boundary conditions and material parameters are set and analyzed.The cutting force and the cutting temperature field in machining process are simulated by the aid of finite element simulation software.According to the simulation results，the changing law of cutting force and cutting temperature field is developed.With the help of cutting experiments，the correctness of the finite element simulation model and the reliability of the simulation results are verified.
