Abstract

In the paper on the basis of the technical literature analysis, reference and regulatory sources and experimental studies, it was found that there is one common circumstance as a reason for the significant discrepancy between the calculated and actual values of cutting speed, cutting force components, and the value of the roughness parameter in the development of turning operation for carbon, structural, and corrosion-resistant steel. It is the probabilistic nature of the formation of contact pairs “carbide tool–steel workpiece”, the absence of mathematical models for real-time accounting of their thermophysical properties, and the orientation of the calculation models on the average value of these properties from the entire permissible scale of variation. From the standpoint of high-speed plastic deformation of machined steels, the authors have proposed some cutting modes for a preliminary test run as a test method for obtaining operational information about the variable thermophysical properties of contact pairs “carbide tool–steel workpiece” directly on the cutting machine.
