英文摘要：

In this paper,the State-of-the-Art of tool wear simulation at home and abroad is introduced,several common methods for predicting tool wear are discussed and advantages and disadvantages of various methods are summarized.In recent years,the powerful numerical analysis of finite element simulation technology has been widely used in the prediction of tool wear in cutting process,It is introduced in detail in this paper and the key technology of predicting tool wear by using finite element method is described,including the establishment of finite element model,the establishment of the tool wear rate model. Finally,the future development direction of the tool wear simulation is discussed.
