ABSTRACT:
A control circuit contains, instead of the otherwise conventional feeler or scanner contact, a displacement pick-up or displacement path transmitter which delivers pulsating signals representative of the irregularities of the scanned grinding wheel. The effective value of such pulsating signals, measured over a scanning or feeling interval, is dependent upon the wear of the grinding wheel or constitutes a measure of the compensating adjustments or repositioning displacements of the grinding wheel. The evaluation of the output signals of the displacement path transmitter or pick-up delivers data concerning the properties of the surface of the grinding wheel, the time during which there is to be undertaken a compensation feed of the grinding wheel, the frequency of the compensating feed and the degree of the compensating or adjustment feeds of the grinding wheel, and specifically, for the positional readjustment and dressing of the grinding wheel both in axial and also in radial direction.
