Abstract

The upper-Bound method is applied to the analysis of the roller burnishing process. In this analysis spherical velocity field with the stream function is used in roller burnishing. A minimization technique of the total dissipation energy rate involving arbitrary variables was presented under a given roller burnishing condition. The influences of burnishing conditions such as burnishing depth, feed speeds and bulges on the roller-burnishing load were discussed. Roller burnishing experiments were also conducted on internal surface of SUS 304 cylinder with various burnishing conditions. The experimental results were compared with the analytical ones. The burnishing force obtained by the upper-bound method agreed with the experimental data.
