Loyev V. Improvement of finish machining of flat extensive surfaces of parts by combining of cutting and surface plastic deforming

The dissertation is devoted to improvement of finish machining of flat extensive surfaces of parts, made of hardened steels, hardened and cast irons by combining of cutting and surface plastic deforming (SPD) by an on purpose designed tool, equipped by superhard materials. Within one cut there is combined stepped face milling, finish planning with variable angles and cutting speed and surface plastic deforming by smoothening with rotation of indenter around the surface being machined. The existing combined methods of machining and tools for their implementation are analyzed, the reasons which restrain introduction of cutting in combination with SPD are determined. The new method of combining of cutting and SPD and tool for its implementation are developed on the basis of this analysis. Testing of the developed method and introduction in conditions of real industry were conducted.
