Apparatus for compensating for dressing tool wear during the dressing of grinding wheels

摘要

The dressing tool is mounted on a cross-slide so as to be displaceable in parallel and normally with respect to the working surface or face of the grinding wheel which is to be dressed. After each dressing operation the grinding wheel is re-adjusted so as to be repositioned in a defined plane. A displacement measuring system is operatively coupled to the grinding wheel in order to measure the amount of such re-adjustment or adjustment. A difference observed between the desired amount of dressing and the measured amount of adjustment indicates the extent of wear of the dressing tool. The dressing tool is then correspondingly further adjusted and the grinding wheel is subjected to a further dressing operation.
