Grinding using diamond wheels is the most important method for machining engineering ceramic because of its high hardness and brittleness. But in a grinding process, ceramics generate an intense grinding force and render surface damage. Surface damage caused from the grinding can reduce the intensity of the work piece and affect the surface quality. In order to suppress surface damage, a model for the surface fragmentation damage was established in this work based on the one-way trip grinding experiment and surface fragmentation damage observation of Si(3)N(4), Al(2)O(3) and ZrO(2) ceramics. By inputing grinding parameters into this model the surface damage can be predicted and controled. This allows optimization of the ceramic grinding process by which we can increase the productivity, and reduce the grinding damage and the processing costs.
