<p>An abnormality monitoring unit for a numerical controlled machine, in which an error display is given on the basis of a comparison between finish pattern information and axis-shift information formed from an NC machining information. After the finish pattern information (INF-A) and the machining information (INF-B) in an NCtape are stored in a finish pattern memory device (31) and a machining information memory device (32), respectively, an axis-shift simulating device (33) simulates the shifting of the axes each time the machining start signal from an NC device (1) advances by one block. An error display device (34) compares the finish pattern information with the axis-shift simulating information and creates the error display if the axis-shift is about to proceed into the interior of the finish pattern.</p> |
