DYNAMIC MEASURING OF NUMBER OF GRINDING EDGES AND DETERMINATION OF CHIP PARAMETERS.

A measuring equipment is presented with which the active edge density is measured as a function of the ″injection angle″ of the workpiece material flow into the grinding wheel. The results obtained make possible a determination of the active edge density for different grinding processes and grinding data. The contact arc of the individual active edge in relation to the real contact arc can be determined, as well as the maximum area of the undeformed chip section of the individual edges. Because the measurement is made continuously during several wheel revolutions, the dynamic behavior of the wheel can be studied.
