Abstract

Based on the theory of cutting mechanics, using a model experiment, the basic laws of the interaction of surface microroughness with a tool have been established, which allow developing a theoretical model for the first stage of finish anti-friction non-abrasive processing (FANT), which will ensure the efficient course of the micro-cutting process and the filling of microcavities with anti-friction material. It is noted that during the interaction of cast-iron microroughness with a brass tool, the top of the microroughness dulls with the formation of a rounding radius. The mechanism of forming the radius of rounding of micro-roughness is shown, a significant interdependence between it and the front cutting angle is established. The phenomena occurring on the back surface of micro-roughness are revealed. The ways to improve the efficiency of the micro-cutting process by ensuring the established values of the rake cutting angle are proven. It is proposed to consider the application of FANT anti-friction coatings from the perspective of a systematic approach and the principles of self-organization, which will make it possible to predict the achievement of optimal quality parameters of the surface layer: equilibrium roughness, favorable microrelief, required hardening, and residual stresses.
