Abstract
Modeling is carried out of the discrete plastic deformation of the rough surface of a metal part by a sliding rigid tool with a circular profile. This modeling is based on the theory of the plane deformation of a perfectly plastic solid taking into account the Prandtl contact friction. The number of discrete contacts and the plastic stress–strain state are determined by the periodic shape of the rough surface, as well as the radius and the vertical displacement of the tool with regard to asperity summits. The plastic smoothing mode used to reduce the surface roughness without the deformation of the core of the metal part is considered.
