Kinematic analysis of the roller ultrasonic vibration burnishing

Burnishing is a mechanical surface enhancement technique by inducing plastic deformation in component´s surface to provide a good surface finish as well as hardened layer in the near surface. Ultrasonic Vibration Burnishing (UVB) is an advanced form by combining the advantages of processing continuity with larger force of burnishing and dynamic impact effect of shot peening, which can greatly decrease the tribo-adhesion wear and more importantly produce excellent nanocrystalline surface. The kinematic law of the roller UVB is established, the relation between the roller UVB depth, the roller UVB force and the roller UVB time and their maximum values is derived, and the required real power of the vibration generator is then obtained. The average burnishing force and frictional force of roller UVB are only about 54% that of conventional burnishing. The above adopted assumptions and the expressions worked out are validated by experiments and related literatures.
