Abstract
Burnishing is a plastic deformation process in which force is applied on to a metal surface through a hard roller or ball. In this paper, an attempt has been made to investigate the optimum burnishing force, change in dimension and the variations of tangential and normal forces in the process. Expressions were derived to calculate analytically the following:
(i) optimum burnishing force,
(ii) size change in burnishing.
The accuracy of these expressions was verified by suitably conducted experiments. Five non-dimensional numbers of importance to burnishing were established. The variation of normal and tangential forces in roller burnishing (and so the coefficient of friction) was investigated experimentally.
