Plastic deformation of the surface layer’s microroughness by a sliding tool with strong contact friction

Resumo

The plastic deformation of the discrete contacts of a tool with a circular-arc and an inclined profile with the periodical microroughnesses of the metallic part’s surface layer is modeled. The plane deformation theory of a perfectly plastic body is used. The plastic deformation process of the surface layer’s microroughnesses by a sliding tool with Prandtl’s high contact friction in which the plastic shear occurs in the direction of the slide of the tool, with the microroughnesses’ depressions being filled and a decrease of the surface roughness, is studied.
