“…Diamond is not suitable for grinding ferrous metals despite its hardness. This is attributed to attritious wear caused by reversion from diamond to graphite [127]. Degradation of diamond appears to be aggravated in the presence of iron low in carbon.…”

The manufacture of high performance grinding wheels is heavily dependent upon the selecting the correct abrasive grain in terms of cutting ability, fracturing ability and the shape of the grain that controls metal removal rate, dressing interval, coolant delivery to the wheel-workpiece interface and chip evacuation. This chapter explains the recent developments in abrasive grains and bonding systems and should allow the reader to better select the correct abrasive grain and bonding system to economically machine materials.

Fracture-dominated wear of abrasive grains is the most important mechanism of material removal from an abrasive wheel during the grinding process. Fracture occurs as a consequence of tensile stresses induced in the abrasive grains by grinding forces to which they are subjected. Experimental work is extracted from the literature and compared with a model abrasive grain using a variety of abrasive grain materials such as alumina, silicon carbide, cubic boron nitride and diamond, with loads applied to the apex and the rake face of an abrasive wedge. The relationship between the wear of grinding wheels, component grinding forces and induced stresses in the model abrasive grains is described in detail. A significant correlation is found between the maximum value of tensile stress induced in the abrasive grain material and the appropriate wheel-wear parameter (grinding ratio). It is concluded that the magnitude of tensile stresses induced in the grain material by grinding forces at the rake face is the best indicator of wheel wear during the grinding process.
