This article describes application of the method of turning the cylindrical surface of the part using the flank surface of the cutting plate. The comparison of classical turning and the use of ‘back turning’ was carried out, the area of rational application was revealed and the combined use of the methods was proposed. A finite element model of the part, tool and equipment was created for calculating deformations in the system and internal stresses. A control program for part machining using a combination of both machining methods was designed.

This article addresses the problem of increasing tool life by applying a wear-resisting coating. However, the lack of technology-based methods and optimal regimes complicate this process. A method for finishing plasma hardening of metals which allows evaluate the quality of the wear-resistant thin-film coatings and optimize application regimes have been advanced.
