PROBLEM TO BE SOLVED: To provide a numerically controlled machine tool for automatically carrying out processes ranging from the disconnection of normal working to the resumption of normal working after the interrupting working only by making a working disconnection instruction. SOLUTION: A numerically control device 10 is provided with a processor (CPU) 16 for sending an operation instruction to a machine tool 1 by executing a first working program 12 or a second working program 14. The CPU 16 is configured to accept a command to carry out interrupting working by a switch operation or the like from an operator. The numerical control device 10 is also provided with an auxiliary memory 18 for temporarily storing data necessary for the resumption of working of a first workpiece. COPYRIGHT: (C)2007,JPO&INPIT
