“…The analytical model is favorable in universality and scientific settings [6]. The research, done by Li et al [6], developed analytical models for both ball and roller burnishing on hardened steel and aluminum that showed the constant coefficients that contributed to surface roughness (Rt) only depended on yield stress.…”

“…The FE model solves the problem of burnishing mechanisms; however, it is specific to a particular configuration, like the empirical model, thus can hardly be applied to other cases [6], and a clear representation of process mechanisms is required [11]. In general, the residual stress distributions are quite interesting to simulate in FE model due to the significant influence on fatigue life.…”

“…The simulations were made to analyze the surface profile, the residual stresses and the influence of burnishing parameters on surface roughness and the residual stress distribution. Li et al [3] proposed an analytical model for surface roughness during the burnishing process. They proposed a burnishing mechanism in which the geometries of the burnishing tool and workpiece, the microscopic topography of the surface and the mechanical properties of the workpiece were taken into consideration.…”
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.
“…Yen et al also constructed an FEM model of roller burnishing and analyzed the residual stress on the burnished surface [3]. Li et al reported an analytical prediction of surface roughness during roller burnishing with experimental verification [4]. El-Tayeb et al investigated the influence of the contact condition between the roller and workpiece on the burnished surface quality as well as the tribological behavior in roller burnishing of an aluminum alloy [5].…”
