PROBLEM TO BE SOLVED: To provide an NC machining program managing method simply replacing an NC machining program by storing over the restriction of a physical memory capacity. ;SOLUTION: An NC device with an NC program memory 24 storing the NC program memory 24 storing the NC machining program and an auxiliary storage device 14 of an access time longer than the memory 24 collectively manages a group of mutually related NC programs as one individual group and manages a group of NC machining programs used in common by NC machining programs belonging to plural different individual groups as a common group. NC machining programs respectively belonging to one individual group designated by the name of a group and the common group are loaded to the memory 24 and at the time of loading another NC machining program to the memory 24, an NC machining program belonging to the individual group is replaced for loading.;COPYRIGHT: (C)1998,JPO
