Tool performance prediction of fabricating humps on different cutting tools by Numerical Analysis

In this paper, the effect of humps on tool properties and cutting process on tool surface is studied. It is found that the tool temperature in cutting process can be effectively reduced and the wear of tool tip can be reduced by adding humps to three standard tools and carrying out simulation analysis. Humps on tool surface can reduce chip thickness by secondary cutting, which is beneficial to chip breaking. Humps on different cutting tools can effectively improve the performance of cutting tools. This paper can effectively guide the preparation of special cutting tools.
