Wear Analysis for Non-smooth Surface HSS Cutting Tools

In order to improve cutting tool wear resistance, non-smooth surface was applied on HSS cutting tool and finite element method was used to analyze the wear of non-smooth surface HSS cutting tools. The orthogonal simulation test was established to analyze the influence of parameters on tool wear and the relationship between parameters and tool wear was discussed. Simulation results show that non-smooth surface could significantly improve the wear resistance of cutting tool. The line space has the most influence on cutting tool wear. The ranking of parameter influence on tool wear are line spacing, pit diameter and column spacing. And the lower tool wear usually occurs at points of pit line space which is three times as pit diameter.
