Abstract: Research presented indicates that grain fracture is the most important mechanism of material removal from sharp abrasive wheels during grinding. The relationship between the wear of facets and vertices on the surface of microgrinding tools and the induced stresses in model abrasive grains is described in detail. It is concluded that the magnitude of tensile stresses induced in the abrasive layer depth is the best indicator of microgrinding tool wear during a grinding operation.
