The material-removal rate is obtained by considering the geometric intersections between grinding wheel and workpiece, as well as the multiple grains involved in cutting. To define the model of material-removal rate Q w, the equation of chip thickness and the section cut by a grain A c g was first obtained.

Grinding wheels are abrasive cutting tools. The abrasive grains distributed on the surface of the wheel form thousands of cutting points capable of cutting away tiny chips of material. These grains are held together by a bond, in most cases a mixture of selected clays, and separated by pores. When the wheel is in use, the abrasive grains …
