Abstract
The article presents the results of experimental studies to determine the influence of the main technological parameters of reverse surface plastic deformation (SPD) on the temperature in the contact zone of the working tool with the workpiece. To implement the proposed method of finishing and hardening processing, a device has been developed that provides a reverse circular movement of the working tool. Using a FLIR SC7000 series thermal imager, the temperature in the contact zone of the working tool with the workpiece was determined. Experimental studies have shown that the value of the temperature on the surface of the workpiece with reverse SPD varies from 42 to 123 °C and depends on the main technological parameters of the process. It has been established that the temperature exceeding 123 °C at the contact leads to a decrease in the maximum intensity of residual stresses in the surface layer of the part. Based on the results of experimental studies and using the PyCharm computer program with the Python programming language, optimal hardening modes were determined that provide the minimum surface temperature of the part, which makes it possible to maintain the quality of the surface layer after hardening.
