The account of hardening of a material of a surface layer of the parts, processed by turning, at calculation of the residual stresses coused by thermal factor
The method of calculation of the residual stress in a surface layer of a details from arction of the heat factor at acceptance of the linear law of hardening parts of the material is offered. When calculating the recorded physical and mechanical properties of the processed and a tool’s materials, the processing mode, the geometrical parameters of the cutting part of the tool.
