Abstract :
This paper mainly uses ABAQUS Explicit finite element analysis to establish a two-dimensional model about the micro cutting process of Guide abrasive wear. The Johnson-Cook constitutive model is used to simulate the stress changes in the process of guide wear. Simplify the particle as a circular, like a small tool to cut the surface of the guide rail. Treating the particle radius as the corner radius, we study the impact on the stress of the guide rail wear process in different cutting speed and radii. The simulation data is obtained by orthogonal cutting experiment and regression model is analyzed by MATLAB, the regression equation and the influence laws of various factors to the stress changes are acquired.
