High-Performance Finishing Technology in Turning with Leading Plastic Deformation

The purpose of this work is to give a new technological solution to the problem of intensification of finishing and fine machining when turning with leading plastic deformation. We experimentally confirmed that the use of a hardening device with the possibility of simultaneous contact on the two surfaces of the workpiece - cutting surface and machined surface - allows us with relatively high feedrate (up to 0,53 mm/Rev) provide roughness achievable in finishing and fine machining at S ~ 0,06 mm/Rev. Findings of the research show that the energy similarity and good compatibility with respect to the physicochemical action mechanism on the machined material by cutting and methods of surface plastic deformation are the basis for creating technologies with a complex of high technical and economic indicators for productivity, the period of cutting tool resistance, the quality of the surface layer, in particular, roughness and favorable residual stresses.
