Study on the surface generation mechanism in machining

Kobayashi A, Mizutani T., Kurata Y.

1999

Vol. 4, no spec.

285-290

Surface generation mechanism by the burnishing action in machining has been examined experimentally under various velocity and load conditions. The surface generation characteristics are estimated by the surface improvement ratio ( the ratio of the deformed asperity heights and the original heights ) and the plastic flow pressure, Pm, based on the junction growth theory of Tabor (1959). Burnishing velocity in this study's region does not influence the friction coefficient (the ratio of burnishing load and friction force). The tip of asperity deformed plastically by burnishing action mainly flows in both sides of the asperity.
