【Abstract】 The adiabatic shear is an important phenomenon in cutting, n has important significance to the cutting of the hard - cutting materials and the development of the high speed machining. This paper presents an overview of the study of the computer simulati on of the cutting process in abroad and home . The critic technologies of it are introduced. Eventually, the disadvantage of the computer simulation technology of adiabatic shear and the direction of its development is provided.更多还原
