Optimization of Micro-Texture Distribution through Finite-Element Simulation

Abstract

The existing studies on micro-texturing of cutting tools only tackle the micro-textures of uniform distribution. The theoretical and experimental bases are severely lacking for the effects of different micro-texture distributions on the anti-wear and anti-friction properties in titanium alloy cutting. To solve the problem, this paper attempts to explore the wear resistance and friction performance of micro-round-pit (MRP) textures in different distributions. Specifically, the DEFORM-3D finiteelement method (FEM) software was adopted to simulate and analyse the effects of these distributions on the ball-end milling of titanium alloy. The simulation shows that the milling force was minimized by the distribution ABC (150-175-200). This result was then confirmed by a milling experiment. In conclusion, the tool wear and cutting friction can be effectively reduced by the optimal micro-texture distribution.
