PURPOSE:To increase the effectiveness and safety of a machine, by providing an interlocking means for stopping a machine operation at the time when the grindstone shaft discriminating data of the grindstone shaft data and grindstone data selected by a work program command means does not coincide. CONSTITUTION:A grindstone shaft discriminating data SE capable of discriminating each grindstone shaft on each grindstone shaft is prestored in a grindstone shaft data memory means 8. Moreover, the grindstone data SG composed of the grindstone tool offset data of the case of using each grindstone on each plural usable grindstones and the grindstone shaft discriminating data designating the grindstone shaft corresponding to this grindstone tool offset data, is stored in a grindstone data memory means 4. Then, whether or not the grindstone shaft data SE of the memory means 4, 8 selected by a work program command means 7 and the grindstone shaft discriminating data SG coincide, is decided by a deciding means 7. In case of the nonconformity of both data as the result of this decision the machine operation is stopped by an interlock means 7. |
