ABSTRACT:
An apparatus for displaying an operation sequence of a machine tool such as a grinding machine which is controlled by a numerical controller. During operation, successive operations instructed by a machine operator are stored in the memory of the numerical controller along with successive numerical commands which are executed during the successive operations. When a malfunction occurs in the machine tool, the storing operation is stopped, and the successive operations and the successive numerical commands executed before the occurrence of the malfunction are displayed on a display device for analyzing the cause of the malfunction.
