Grinding wheels consist of geometrically undefined 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-in coupon.
Other parameters are grain size, grain protrusion and contact ratio of the ground surface. With tolerances of approx. 20 µm and mostly in-process measurements, the requirements for measurement uncertainty and measurement time are high. The surface is partly highly reflective, partly transparent and places special demands on the sensors.
