Abstract: Residual stresses and part distortions produced by the surface machining and mechanical enhancement are jointly analysed. A general case of superficial stress described by the two normal and in-plane shear components is treated. Rigid kinematics processes, for example cutting, ball and diamond burnishing typically produce this state. Inherent strain and stress are taken as initial invariant parameters of the technological process in integral and detailed fashion. Some simplified methods to evaluate integral parameters of the surface treatment are discussed. The methods can help to avoid the expensive investigation of in-depth residual stress distributions at the first step of the studies.

Keywords: burnishing; part distortion; inherent strain; metal cutting; process monitoring; residual stress; surface enhancement; typical distribution; rigid kinematics; surface machining.
