ABSTRACT:
A tooth grinding apparatus uses a cutter grinder to regrind the tooth surfaces of a shaving cutter adapted to cut gear workpieces, the regrinding being performed whenever the tooth surfaces of the shaving cutter become worn. A plurality of tooth grinding data stored in memory in advance are preset in such a manner that the gear workpiece can be cut in dependence upon the state of the shaving cutter tooth surfaces so that the teeth of the gear workpiece will have a target tooth surface shape. The tooth surface state of the shaving cutter is measured, and tooth grinding data, which are closest to the measured tooth surface state, are called from the plurality of stored tooth grinding data. A grinding control unit controls the cutter grinder in such a manner that the tooth surfaces of the shaving cutter are ground based on the called tooth grinding data.
