Analysis of Wear Resistance Based on Milling Topography

Abstract

In the field of aerospace and automotive mold manufacturing, the design and manufacture of wear-resistant surfaces is always an important topic. In this study, high-speed milling method was used to prepare random morphology, quadrilateral pit morphology and hexagonal pit morphology. Firstly, the milling surface forming mechanism of ball-end milling cutter was analyzed, Innovative use of texture angle to distinguish between different morphology. Secondly, a plane wear simulation is set up, the wear resistance of the workpiece was analyzed with wear depth, temperature and strain as indicators. Finally, the wear quality of the three pit morphology was compared by means of friction and wear experiments. The experimental results obtained was consistent with the simulation, which means that the quadrilateral pits have better wear resistance.
