Plastic strength of cutting parts of tools from STM when there is turning heat-resistant alloys

Abstract
The article is devoted to the modeling of physical and chemical creep process, which determines the plastic strength of cutting parts at the vertices of the tools from STM. The creep process is associated with the phenomena of diffusion and diffusion wear of the tool from STM in the zone of quasi-brittle transition (that is, the temperature transition of tool STM from brittle to plastic state at high cut-ting temperatures) with thin turning of heat-resistant alloys and steels. Turning of heat-resistant alloys at high cutting temperatures, corresponding to the quasi-brittle transition, allows the machining process at ultra-high cutting speeds, which expands the application of tools from STM. We have created mathematical model of wear and destruction of the cutting part at the top of the tool and STM due to diffusion phenomena in the process of thin turning of a heat-resistant alloy.
