Plastic Deformation of a Rough Surface by the Rigid Rolling Cylinder

Resumo

Simulation of discrete plastic deformation of a rough surface in an ideal plastic half-space under a rolling rigid cylinder taking into account Prandtl’s contact friction is considered. The roughness of the cylinder is assumed to be insignificant as compared to the roughness of the half-space surface. The regular periodic shape of the rough surface formed after machining with intense cutting conditions is considered. The resistance to the cylinder rolling significantly decreases as compared with the case of the plastic deformation of a rough surface by a sliding tool. The resulting model can be used to estimate the technological parameters for the rolling of a rough surface by wide rollers.
