The article considers the influence of input factors of the laser processing: the radiation power, the longitudinal feed of the laser beam and the distance from the protective glass of the focusing head to the workpiece on the friction coefficient and absolute wear of steel SHH15SG. The greatest influence on the output parameters (friction coefficient and absolute wear) has the power of laser radiation, as it increases, the wear of the surface layer decreases. The obtained multi-factor models and graphical interpretation of the experiment results allow us to assign a laser treatment mode that provides the demanded wear of the treated surface layer of bearing steel. The developed method of assigning the laser processing mode reduces the auxiliary time of the technological operation and eliminates the need for additional experiments in production conditions. The results of the research are useful for manufacturing enterprises that implement laser processing processes, as well as for design organizations that develop modern laser equipment.
