Abstract The article presents the results of studies on the formation of residual stresses due to finish burnishing. Improper state of stresses may arise when, seeking higher dimension and shape accuracy, smaller roughness, or improved plateau area, the production engineer is willing to apply high and very high burnishing forces Fb. Plastic deformations in roughness createdby burnishing can be easily measured with modern profilometers. However, each finish burnishing cut is accompanied by a state of stresses, some of which are residual stresses that remain in the item after machining. Excessively high stresses during the use of products are often causes of the cracking and flaking of surface fragments [1, 2]. One of most accurate methods for the evaluation of residual stresses after burnishing is their modelling taking into account the mechanical properties of material and technological parameter values used in the course of machining. The authors discuss the method of developing an experimental model, its testing, and verification of the results.
