At manufacture of heavy-duty parts, one of the important factors ensuring their safety operation is directional formation of technological residual stresses, nature of distribution of the latter having direct effect on the reliability indices. Concept of the deforming ability of the technological residual stresses was formulated as the moment load intensity adjusted to the surface. The method was proposed for calculation of torques from the effect of the technological residual stresses’ deforming ability as applicable to discrete models of parts with thin-walled elements at turning. Methodical specifics of the computation scheme formation for elastic after-effect of the technological residual stresses’ deforming ability at machining were discussed. Variants of schematization for standard elements of the parts were presented. Pre-requisites were formed for solving the task of controlling residual deformations of parts with thin-walled elements at turning.
