The grinding wheel is a productive and versatile tool. It may be used in fine machining to produce a high degree of geometrical accuracy and surface finish or to provide an effective means for heavy stock removal in snagging operations1. Although grinding is the most common means of metal removal, still much remains to be learned before a fundamental understanding can be claimed. Research has classically dealt with the relations between independent wheel and machine parameters and the dependent variables, surface finish, metal removal rate and wheel wear. The desire for improved productivity, particularly in the fabrication of refractory hard alloys, has resulted in the need for a better understanding of friction and wear in metal-ceramic systems. It is now realized that the action of an abrasive in a metal removal operation is a combination of a mechanical, or strain-energy effect, and a chemical effect. Both contribute to the overall performance. The abrasive grain should possess a combination of properties such that it will not undergo excessively rapid breakdown during grinding. Those physical, chemical and mechanical properties of ceramics which influence adhesion, and in turn friction and wear have already been reviewed2, thus providing an excellent basis for the present discussion.
