The effect of infeed rate on the thickness of the white layer, surface metallography, and specific grinding energies during centreless grinding have been determined, and the maximumgrinding zone temperature calculated. The average thickness of the white layer is a well defined function of the machining conditions, and increases approximately linearly from 0-24 to T53 pm as the infeed rate increases from 0-14 to T56 mm min-1. The surface roughness increases with the depth of white layer, which is formed essentially by a process of intense plastic deformation. The results are discussed in terms of Shaw’s Brinell indentation model of grinding.
