Vibration dynamics and cutting process temperature at various stages of forming the wear of the cutting wedge

Abstract

On today, there is no single and consistent mathematical model describing the complex connectivity of the metal cutting process. Therefore, the article proposes new approach based on the formation of feedback connecting subsystems describing the power, thermal and vibration reactions from the cutting process. The purpose of the work: By forming a consistent model of connections between subsystems describing the power, thermal and vibration reactions from the cutting process to the shaping movements of the tool, you can obtain a description of the mechanism of self-organization of the cutting process in the process of evolutionary changes of the tool. The resulting mechanism is needed to search for some mode of operation of the cutting system, in which further wear of the cutting wedge, cutting force, temperature in the cutting zone and vibration of the tool can be stabilized. Research methods: For processing and analysis of the obtained data, a Matlab package of mathematical programs was used, in which a subprogram was developed that allows a series of numerical experiments. The main conclusion on the work is the provision put forward by us on the self-organization of the cutting system, through the process of evolution of the instrument.
