| Popis: |
Based on the method of the theory of similarity and dimensions using a model experiment, we studied the effect of the force parameters of the finishing anti-friction non-abrasive treatment (FANT) on the micro-cutting process depending on the conditions of contact interaction, which allows a reasonable approach to the formation of an anti-friction coating by the friction-mechanical method. From the standpoint of process mechanics, the role of power parameters on the patterns of micro-cutting is considered. Methods and devices have been developed that allow the simulation of the FANT process, with a phased study of micro-cutting and adhesive sticking of antifriction material on the treated surface. A relationship is established between the force exerted on the surface being machined, the geometry of the microprotrusion, as well as the cutting depth, the application of which allows the use of the methods of the theory of similarity and dimensions to obtain a dimensionless value of force. An analytical relationship has been established to determine the strength for various materials and cutting conditions when applying FANT coatings. Ways to increase the efficiency of the micro-cutting process by providing optimal values of the cutting front angle are indicated. It has been experimentally proved that with an increase in the force of pressing the tool against the work surface to the set value, the continuity of the antifriction coating increases. |
