The study analyzes dimensional changes occurring after the burnishing process related to material displacement after unloading, and consequently, an increase in the height of irregularities. Results were obtained using modern computational tools utilizing the Finite Element Method. An application was developed in the APDL language. Computer simulations were performed in the Ansys program. Results were obtained regarding the dependence of uncontrolled changes in the height of irregularities on the burnishing depth and the deviation of the surface profile. The results are presented in the form of graphs.During finishing, the final basic functional properties of the surface layer are shaped. Under specific operating conditions, these properties have a decisive influence on the durability and reliability of machines. One of the finishing methods that allows for obtaining a surface layer characterized by favorable functional properties is burnishing [1÷4]. It is one of the methods for finishing metals and their alloys, sinters, and plastics, consisting of utilizing local plastic deformation produced in the surface layer of the object [4] as a result of specific (force and kinematic) interaction of a hard and smooth tool (in the shape of a ball, disc, roller, or other) with the machined surface [4].
