Experiment on Optimal Selecting for Cutting Tools in Milling of High Hardened Steel

Abstract

In this paper, with milling characteristics of high hardness hardened steel, we choice six different coated tools to made cutting experiments on high hardness hardened steel Cr12MoV (HRC65). In this stage, through the analysis of cutting force, cutting temperature, cutting vibration, machined quality and tool wear, we have elected the preferred tool and tool geometry parameters for this processing stage. The results of the study show that: TiAlSiN is the most suitable for Cr12MoV (HRC65), which helps to improve cutting processing productivity, prolong tool life, and enhance processing quality and reduce the processing cost.
