Abstract
Today, under the conditions of sanctions, the Russian Federation needs more than ever the development of energy-saving technologies in various industries. The greatest impact on the life and operability of hard alloy cutting tools is exerted by the physical and mechanical properties of tool materials. Studies have shown that the physical and mechanical properties of tungsten hard alloys in the process of operation, namely in the process of cutting difficult-to-process materials under the influence of high temperatures, vary symmetrically. This study was based on the laws of physics of the division of electrodynamics, as well as well-known non-destructive testing techniques, scientific foundations of materials science, all studies were carried out in accredited laboratories of Tyumen Industrial University. Results of research on determination of temperature of maximum operability of replaceable cutting hard-alloy plates based on study of change of electromagnetic properties are obtained. On the basis of persistent tests in factory conditions, it was proved that the developed technique allows determining temperature intervals of maximum operability based on the study of changes in electromagnetic properties of hard alloys.
