The depth of damage induced in ceramics by the grinding process has been determined by means of the lapping and strength testing approach. The depth of damage was determined as a function of the grinding parameter of grit depth of cut. Reaction bonded silicon nitride and toughened aluminum oxide ceramics were investigated. This research establishes how much damage needs to be removed by the finish grinding operation in order to achieve maximum strength of the ground ceramic component. This knowledge is valuable for increasing the productivity of the overall roughing and finishing operations employed in grinding of ceramics.
