Some speculations on the mechanisms of abrasive grinding

The mechanisms of grinding, a predominantly fracture mechanism in brittle material, and polishing, a predominantly plastic shearing mechanism, appear quite different. However, in a number of cases it can be shown that the difference between the two mechanisms can be triggered by differences in depth of cut and abrasive size.

Mechanism of compound fracture and removal in grinding

Abstract. The mechanism of fracture and its removal for low-expansion glass ceramics processing was studied through grinding experiments. A dynamic coefficient K d was proposed to characterise the brittle material processing property. Using surface roughness as the evaluation index, the limitations of the empirical model and the brittle fracture model were analysed.
