Abstract
The influence of shear stresses on the physical processes proceeding on the surface of contact of a cutting tool with a chip removed has been investigated. The mechanisms of appearance of contact layers and the dependence of the lengths of the elastic and plastic parts of these layers on the normal and shear stresses in the contact zone have been considered. It was established that a natural “white” layer formed in the process of cutting plays a protective role and, as a consequence, decreases the rate of wear of the tool.
