In this paper, the finite element models of metal cutting were first discussed systemically, based on metal cutting theroy. Based on the platform of finite element software DEFORM-3D, the processes of metal cutting were simulated and the laws of distribution disclosed for equivalent strain field, temperature field and tool wear were got. The error of the prediction is about 10%. The model has been validated by simulation results to be reliable.
