Grinding wheels consist of geometrically indeterminate cutting edges and a polycrystalline surface. In addition to the profile, angles, radii and distances are measured directly on the grinding wheel or on the grinding coupon.
Other parameters include grain size, grain protrusion and contact ratio of the grinding surface. With tolerances of approx. 20 µm and mostly in-process measurements, the requirements for measurement uncertainty and measuring time are high. The surface is in part highly reflective, in part transparent and places special features on the sensors.
