【 摘 要 】

To achieve the required performance characteristics of the bevel gear, optimization of the tooth cutting process is necessary. At the same time, in order to predict the wear of the tool, the quality and accuracy of the processed profile, it is important to understand the course of the thermal processes that occur during cutting. The paper presents the results of a study on modelling the effect of the design of a cutting tool on the thermal phenomena that arise during processing. The standard analysis of temperature fields does not allow determining the influence of rack and clearance cutting angles on thermal processes, other characteristics of the heat exchange process are considered in the work: heat flux and specific thermal energy. The basis for the work was the new mathematical model. The model developed by the authors represents a set of two different approaches to modelling: analytical and numerical. The developed model makes it possible to perform a numerical experiment with given conditions that are close to real practical ones.
