Machining of ceramics not only generates dimensional tolerances but also influences the surface integrity. The use of a low grain depth of cut results in a surface layer with small or no cracks. A parameter which is proportional to the thickness of cut due to grinding parameters, has unique relations with grinding forces, resulting bending strength and residual stresses. On this relation a predictive grinding model can be based. The large amount of factors influencing grinding, especially wear and run out of the wheel, restricts the use of the model. Creep feed conditions combine high removal rates with low thickness of cut and low damage, but are very sensitive to the grinding set up. 16 figs., 1 tab., 13 refs.
