Research on friction and wear characteristics based on different texture angles of milling topography

Abstract In the field of mold manufacturing, the wear resistance of the mold is a key factor affecting the life of the mold. In order to extend the life of the mold, most scholars have invested a lot of research on the surface texture of the mold. This article mainly analyzes the influence of the texture angle of different milling topography on the wear resistance of the mold. First, we studied the formation process of the milling topography, and distinguished the quadrilateral pit topography and the hexagonal pit topography by defining the texture angle. Secondly, we carried out a wear simulation analysis on the slider with a texture angle, and studied the influence of different topography on the wear depth and stress distribution. Finally, with the help of friction and wear experiments, the wear amount of the slider with different texture angles is tested, and the relationship between the texture angle, the wear quality and the friction coefficient is analyzed. The conclusions obtained provide an effective reference for industrial designers to prepare wear-resistant molds.
