The Effects of Surface Grinding Conditions upon the Grinding Force and the Surface Characteristics of Fine Ceramics

Abstract

The effects of static stiffness of surface grinding machines, and the grinding conditions upon the grinding force and the surface characteristics of fine ceramics are described. There is a critical point in the relation between the table feed rate and the grinding force under the condition of constant removal rate. Fine ceramics ground at a lower table feed rate than the critical point and in an up-cut grinding condition exhibit a surface of quasi-brittle fracture and a greater grinding force. Grinding at a higher table feed rate and in a down-cut grinding exhibits a quasi-plastic flow surface and a lower grinding force. The surface grinding machine with a lower static stiffness exhibits quasi-plastic flow surfaces.
