The mechanism of workpiece removal in grinding is generally explained under consideration of tribological aspects. Grain depth of cut, average cross-sectional area of grinding chips and average cutting-edge spacing are derived theoretically. The given values,however, are not decisive, but change with wheel wear and three-dimensional distribution of cutting edges. Characteristics of wheel-to-workpiece contact are experimentally examined. Cutting ability of abrasive grains, successive cutting-edge spacing,temperature of wheel-to-workpiece contact zone and grinding forces widely change with wheel ware.
