Problem statement and the research purpose. One of the main factors determining the intensity of tool wear is the temperature that arises during the cutting process. Thus, the objective is to investigate the patterns and obtain dependencies of heat generation and heat transfer between the elements of the cutting process that characterize the temperature of the tool’s teeth and blades. The aim is to establish heating and wear of the cutting edges during the machining of internal gears using the Power Skiving method. Methodology. Using a comprehensive interrelated graphical-analytical and mathematical modeling approach, including the creation of a 3D model of the undeformed chip built on the obtained sections, as well as simulations of contact, force, deformation, and thermal processes during the gear cutting of the internal ring, the friction forces and temperature on the teeth of the skiving cutters were investigated. Results. The proposed research methodology outlined in this work allows for selecting safe operating conditions for the cutting tool during the gear shaping process using the Power Skiving method. The obtained results ensure the necessary stability of skiving cutters and help avoid thermal overload. Scientific novelty and practical significance. The results of the study enable the selection of optimal cutting mode values when machining internal gears, considering the technical specifications of the equipment and the properties of the tool material. The selected safe cutting speed will maximize the productivity of this method and provide the necessary durability of skiving tools. Scopes of further investigations on the subject of the paper. In further studies, it is necessary to establish the relationship between the durability period of the skiving tool and temperature for various cutting depth values and during the engagement with the workpiece.
