The wear conditions of cutting tools can be studied with finite element method. This method can not only obtain various parameters in cutting process, but also has advantages in low cost and high efficiency. The key technologies in cutting tool wear with finite element technique was studied. These technologies include the constitutive model, contact type and friction model, wear model and wear calculation, ALE grid technology, separation criterion and fracture criterion. In addition, the existing problems in the current researches were analyzed and the future development were proposed. This paper has guiding the significance for promoting the use of finite element techniques in cutting tool wear.
