Abstract
A machining controlling apparatus numerically controls a wheel spindle stock and a spindle apparatus, and performs the machining operation of a workpiece by a grinding wheel. When a power failure has been detected by a power-failure detecting unit, a grinding machine is stopped after the grinding wheel is retreated from the workpiece within a very short period until the controlling operation by the machining controlling apparatus becomes impossible.
