Simulation Analysis of the Influence of Micro-texture Parameters on Tool Strength Based on ANSYS

Abstract

In this paper, the influence of the micro-texture parameters of the tool surface on the tool strength is studied, and the texture parameters with less influence are selected.Firstly, the cutting force of the PCBN tool in the actual cutting process is measured by the dynamometer, and then the 3D model of the tool is imported through the finite element analysis software ANSYS. After the mesh is divided, certain constraints and the measured cutting force are applied, and finally get the deformation and equivalent stress of the tool for analysis.The results show that when designing the micro-texture, the width of the micro-texture should be between 90-110μm, the spacing of the micro-texture should be between 110-120μm, and the margin between the micro-texture and the cutting edge should be between 160-180μm. The depth of the micro-texture should be between 30-40μm, so that it can not only play the role of micro-texture on the cutting tool, but also reduce its impact on the strength of the tool.
