The article presents the results of modeling and studying the processes of cutting internal gears by the power skiving method based on the previously developed graph-analytical model of cut layers. The results of the calculations of the geometrical parameters of undeformed chips can be used to calculate the forces that occur in the process of four-pass gear cutting and influence the parameters of this process.

The possibility of increasing productivity by increasing the cutting parameters of difficult-to-machine materials, using expensive tool materials, etc. is an extensive trend of innovative improvement and is accompanied by high costs of operations and the need to provide expensive equipment. The article argues that a more effective method of improving machining operations is the use of the workpiece Turning with Preventive Heating (TPH) method.

This article explores the formation of non-deformed chips during the cut-in of an internal toothed ring using the Power Skiving method. This pivotal stage of the cutting process poses significant hazards not only in gear cutting but also in any cutting operation. The study involved modeling the process at the initial stage for various technological parameters, including cut-in depth and number of working passes. To achieve non-deformed chips, a methodology developed for worm milling was applied.

Simulation of the dose rate of building materials γ-radiation in the premises of different designs has revealed the minimal levels of human exposure. It was determined that the exposure dose rate at the given points of a single room depends on the content of natural radionuclides in construction materials and the changing geometry of a person's exposure in the premises. When the exposure dose rate of γ-radiation above an individual plate is determined, it is conventionally divided into the discrete sources, the dose rate from several plates is summed up.
