Analysis of the texture direction of the milled surface on the wear resistance of the workpiece

Abstract

Wear is an important cause of surface failure and material loss of the workpiece. This paper analyzed the influence of different texture directions on the wear resistance of the workpiece produced by the ball-end milling surface. Firstly, the surface topography formed by the ball-end milling was established. Based on the Archard wear model, the Fortran language was used to write subroutines, and the Adaptive-Lagrange Euler (ALE) meshing technology of the Umeshmotion module was applied in the simulation software ABAQUS to establish a new wear simulation model; Secondly, the wear mechanism was analyzed based on factors such as contact pressure, contact area and wear amount, and the best wear-resistant texture direction was obtained; Finally, the wear resistance of the surface was analyzed according to the three-dimensional roughness parameters, the three-dimensional roughness parameters that have a greater influence on the wear resistance of the milling surface were chosen, and used the three-dimensional roughness parameters to establish the prediction model of the milling surface texture on the wear amount. This paper provides a new method for predicting the wear amount of milling topography by using three-dimensional roughness parameters. The result is of great significance for selecting reasonable milling parameters and improving the wear resistance of the workpiece surface.
