【Abstract】 The recent research and development in twist drill modeling is summarized. The performances and features of three kinds of FE software they’re suited to simulation of the cutting process are compared,and some key technologies in the Finite Element Modeling are discussed. At the same time,the application of the FEM simulation in the drilling operations is systematically introduced,and finally the open question and trend in development of FEM simulation for the drilling process are presented.更多还原
