Purpose. To confirm the influence of the previously obtained theoretical dependences of the cutting conditions on the geometrical forming precision and quality for the valve seats overhauled surfaces in the timing gear of the internal combustion engine. Methodology. The practical research of the valve seats quality parameters was carried out with the usage of modern control means and software. Results. The practical dependences of the different cutting conditions influence on the quality parameters of the processing surfaces were obtained. Scientific novelty. Completed work allowed to perform an analysis for the presented previously mathematical models and practically received dependencies. The discrepancy between the theoretical and actual data was defined in the certain range.. Practical importance. The completed analysis admitted to identify rational modes of cutting conditions to ensure the necessary quality parameters of the machining surfaces within valve seats overhaul process in the auto repairing industry.References
