In the article the model for forecasting of thermal processes arising during processing of bevel gears is presented. The kinematics of cutting is modeled due to the analytical model. Chipping is modeled using the finite element method. The experiment is based on the method of infrared photography of the cutting process. In the process of carrying out a numerical experiment, the graphs of the heat fields for the tool, the workpiece gear and chips were obtained, and an array of data on their change during the cutting process was achieved. The simulation results showed that the maximum temperatures and heat flows in the tool depend significantly on the choice of the rake and clearance angels of the cutting.

The article shows the possibility of determining the correction coefficients necessary for calculating the cutting force. To calculate the correction coefficients, we use the model of mechanical processing of nonvolvent gears proposed by the authors. Using this approach allows you to eliminate some of the expensive experimental research and reduce the cost of design and technological preparation of production..
