This article presents the results of experimental studies on the influence of centrifugal shot peening parameters on the impact force Fu occurring during the machining of the EN – AW 2024 aluminum alloy. The surface roughness parameters Ra, Rt, Rpk, Rvk and surface topography were also analyzed. Centrifugal shot peening was carried out on the FV-580a vertical machining center using a centrifugal shot peening head. Variable parameters of the centrifugal shot peening were: tangential speed vg and infeed g. On the basis of the results obtained, it was found that the increase the tangential speed vg and the infeed g causes an increase of the impact force. After centrifugal shot peening, numerous micro-cavities were formed on the surface of the EN-AW 2024 aluminum alloy samples, which may can accumulate lubricants in their space. During centrifugal shot peening, low values impact force Fu were obtained, which confirms the legitimacy of using this method as a finishing machining of elements with low stiffness.
