Simulation of the performance properties of cutting tools with coatings for specified operating conditions

Abstract

The paper presents the results of solving the problem of choosing a cutting tool with coatings for the given conditions of its subsequent operation using the capabilities of computer modeling of the architecture of coatings of hard-alloy tool materials. The results of the predictive tool material design for the specified operating conditions with a high degree of reliability allow us to evaluate the performance of tool materials in actual operating conditions. The developed computer models of cutting tools multilayer coatings are adequate, and the results of the calculations correspond to the experimental data obtained under the specified operating conditions of the tools. The novelty of the proposed approach consists in the development of the methodological foundations for the design of multilayer coatings of tools based on the analysis of computer simulation results of its stress-strain state during the cutting process.
