| Abstract: | In view of the questions in theoretic analysis and numerical simulation with the finite element method,the separation criterion of chips, the surface contact, the setting of friction coefficient,and the thermal stress coupling are researched. A simulation example is presented by applying the finite element analysis software-ANSYS,and the change of stress and strain in metal cutting process, the forming of shear plane and the influence of the temperature field on metal cutting are analyzed. The tool's strength is also analyzed. |
