Abstract :In order to solve the problems that the types of surface integrity modeling methods in metal cutting are various and the revelation for the relationship between the methods is not clear ,the main modeling methods for such surface integrity indexes as the surface morphology ,residual stress ,work hardening and phase transformation were summarized.From the view of both application scope and main achievements of each modeling method ,the research status of surface integrity modeling was generalized.The advantages ,disadvantages and their internal relationship of both analytical and numerical modeling methods in predicting each surface integrity index were discussed.In addition ,the effect of numerical simulation technology in the surface integrity modeling was mainly analyzed.The difference and relation in the research systems for the surface integrity at home and abroad were indicated.Moreover ,the development direction of surface integrity modeling was prospected.
