Effect of Periodic Fluctuations of Cutting Mode Parameters on the Temperature of the Front Face of a Turning Tool

Introduction. Modern research aimed at improving the efficiency of the workpart procedures emphasizes the importance of taking into account the effect of periodic disturbances on the cutting dynamics. However, few works consider uncontrolled periodic disturbances, whose sources are spindle units and the supporting system of the machine. These disturbances also have a significant impact on the final quality indicators of the cutting process. Therefore, an urgent task in the mechanical engineering technology is to establish patterns of the effect of uncontrolled disturbances on the dynamics of the cutting process, which is particularly important for the development of systems for the automated selection of operating conditions or vibration diagnostics systems. This research is aimed at determining the mechanism of influence of periodic fluctuations of processing parameters caused by vibration disturbances on the temperature of the front face of the turning cutter, which is the key indicator of the development of diffusion wear of the carbide tool.
