Abstract
Features of parts machining in rotor-screw technological systems are presented. It is shown that the mass of the load, consisting of the processed parts and the granulated working medium, is located along the internal perimeter of the screw rotor asymmetrically to the axis of its rotation. In this regard, there are difficulties in designing the rotor-screw machines drive, and in the rationale for its optimal power. A technique is proposed for calculating the drive power of rotor-screw machines, which makes it possible to carry out a techno-economic assessment study of their applicability for finishing-hardening machining of parts in machinebuilding production. The technique is illustrated on the basis of justifying the drive power of a rotor-screw machine for hardening the details of St3 steel in a screw rotor mounted from 9 octahedra, steel balls are used as a working medium.
