Opis:
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.

Opis:
The paper presents the results pertaining to an analysis on the influence of technological parameters of pneumatic shot peening technology on the selected properties of a surface layer of butt joints made with Friction stir weld‑ ing (FSW) method. Butt joints made of two 2024‑T3 aluminum alloy sheets with the thickness of 1 mm were shot peened with glass beads. The experiments were carried out according to the statistical 3‑level completed plan PS/DC 32 . The technological parameters were changed in the range: pressure p = 0.4–0.6 MPa and peening time t = 1–3 min. As a result of the conducted research, adequate equations describing the effect of the analyzed parameters on the surface roughness were obtained. Shot peening with glass beads significantly reduced the sur‑ face roughness from Ra = 5.2 µm to Ra = 1.42 µm. This treatment provides high compressive residual stresses and the increase of the surface layer hardness. The results show that shot peening is a highly efficient and cost‑effective mechanical treatment used for improving the mechanical properties of the butt joints made with the FSW method.
