【Abstract】 The analytical heat transfer model for orthogonal cutting is presented. The temperature fields in cutting tools are simulated by means of Lagrange method of Finite Element Method (FEM). The influences of rake angle and feed rate on cutting temperature are obtained, which provides valuable references for the investigation of tool wear mechanisms so as to increase tool life.更多还原
