Comparative Analysis of Simulation Results of Hard-to-Cut Materials Machining by Coated Cutting Tools

Abstract

The article describes the system approach to simulation the process of machining hard-to-cut materials using tools with wear-resistant coatings. In addition to increasing the wear resistance of the tool, factors such as thermal state model, load parameters and friction behavior at the tool-chip interface have been analyzed. A comparative analysis of these parameters is described in the article. It has been proven that the greatest wear of the cutting edge does not occur on the top of the tool, but in the area where the chip speed along the rake face of the cutting insert is greatest.
