PURPOSE:To know an operation state of a numerical control machine tool in an optional time band by using a means which contains a memory to store and the operation record information on the machine tool and delivers the stored record information. CONSTITUTION:A display 5, a keyboard 6, a processing memory 7, etc. are connected to a main control part 2 of a numerical control machine tool 1 via a bus line 3. While a mechanism part 13 is connected to a shaft control part 11. In a processing mode the part 2 delivers a processing command to the part 11 by a program PRO stored in the momory 7 and according to a processing start command MS of an operator given from a keyboard 6, etc. The part 2 monitors the processing execution state of the part 11 and the processing information MI on the processing time points, the number of works processed, etc. are stored to an operation record buffer memory 9 in the form of the operation record information DIR. The alarm information and the processing information produced in an operation mode are delivered optionally by a hard copy output means such as a printer 10, a tape puncher 12, etc. |
