Grinding wheel selection is governed by matching the abrasive grit, bond type, structure, and wheel grade to the physical and chemical properties of the workpiece material, since the grit-workpiece pair must be both mechanically compatible and chemically inert to avoid premature grit degradation. Abrasive machining relies on grains of indeterminate geometry held in a bonding matrix, in contrast to the defined-geometry cutting edges of milling, and wheel behavior is characterized by an alphanumeric specification system covering grit type, size, hardness (bond strength), structure (porosity/spacing), and bond material. Wheel conditioning (trueing and dressing) restores geometric accuracy and grit protrusion, controlling chip clearance and cutting efficiency over the wheel's service life.
