Research of Temperature Phenomena During Machining Surface Plastic Deformation of Detail

Surface plastic deformation of rollers is widely used to ensure the specified quality parameters of the surface layer of machine parts during their processing. Thermal processes during the processing of details by superficial plastic deformation of rollers can significantly influence the quality of the surface layer. In the article, the issues of identification regularities of the influence of processing modes and design parameters of deforming rollers at surface plastic deformation of a detail on the formation of temperature in the contact area between a deforming roller and a processed surface are considered. The known literature references do not provide uniform data in terms of applied calculation methods, therefore, it makes it difficult to conduct a comprehensive analysis of obtained dependencies and limits the ability to compare different options. The mathematical model is based on studying the process of a surface plastic deformation of calculating temperature in the contact region. Based on the research of resulting mathematical model, it is established that the temperature formed in the contact zone is much smaller than the permissible one at which there can be a change in the quality parameters of the surface layer.
