Estimation of technological and thermobaric features of hardened steels machining: description of phenomena in the contact zone by cutting with blade tools from PCNB group BL

Abstract

So far, the development of modern tribology in the mechanical assembly industry requires the search for new tool materials, consideration of technological capabilities of cutting tools and determine the optimal characteristics and process conditions with the definition of cutting modes for machining. But the main role in the processes of technological processing is formed by the tool used to achieve maximum results at minimum cost. Their operation is characterized by significant loads, so for the processing of machine parts and mechanisms it is advisable to use structural materials with high mechanical properties. Hardened steels, heat-resistant, corrosion-resistant and hard alloys, and other high-strength materials have become widely used in industrial industries. Processing of such materials is successfully carried out by the tools which are equipped with polycrystalline cubic nitride of boron (PCNB). Such alloys have high temperature resistance, high hardness, which allows them to be used in high-speed cutting operations.
