This paper deals with the problem of forming a surface roughness profile of a machined surface and a definition of the optimal depth of penetration in ball burnishing which would allow minimization of surface roughness. The assumptions, which have been numerically and experimentally verified, claim that maximum surface quality, i.e., minimum surface roughness, Ra, is achieved when the depth of ball penetration into the workpiece material is approximately equal to the maximum peak height, Rp. For the purpose of numerical simulations, a surface roughness model based on milling kinematics was used. Numerical simulations and the used roughness model support the claim that penetrating with a stiff tool up to the mean line of the roughness profile yields best surface quality. The authors maintain that ball penetrations, which exceed Rp, cannot significantly improve surface quality. Furthermore, the phenomenon of profile peak deformation is substantially clarified. The analysis of internal stresses within the workpiece after ball burnishing allowed a relationship to be established between internal stress distribution along the depth of the hardened layer and ball penetration depth.

“…The results indicated that burnishing force and number of passes were the significant factors for surface roughness. Tadic et al [9] discussed the effects of the ball burnishing process taking into consideration the initial surface roughness. Burnishing was performed using an especially designed high-stiffness tool.…”

“…Ball-burnishing process is a mechanical surface treatment, eventually used for the finishing of functional mechanical surfaces [1]. It is widely practiced following the machining of the cylindrical surfaces [2], spherical [3], concave or convex [4], flat [5,6], or complex surfaces [7] of mechanical parts. This post-machining and low-cost finishing process is often applied to improve the surface integrity of aluminum alloys, which are difficult-to-grind with the high-cost conventional grinding as mentioned in the work of El-Axir et al [8].…”

Presented in this work is a study on construction stiffness, based on examination of their neutral lines for various cross-section geometries and different force magnitudes. Investigations were conducted both through numerical simulations and experimentally. The results of numerical simulations indicate that stiffness enhancement reduces deflection in the range of 41-52 %, while the experimental tests showed the reduction of 42-54 %. Also reviewed is comparative analysis between the stiffness results obtained by numerical analyses and experiments, which showed high degree of their compliance. The deviations between the results offered by the two methods are 1-3 %, on average, while in the worst case, which occurs in just a couple of points, the deviation equals 10 %. This study revealed significant increase of element stiffness, which was obtained by employment of additional stiffness enhancing elements.
