ABSTRACT:
A numerical control unit in which command data is inputted from a keyboard and stored in an internal memory and which controls a machine tool based on the stored command data. A cassette type memory is constructed to be detachably mounted on the numerical control unit. When the cassette type memory is mounted on the numerical control unit, the command data can be transmitted between the cassette type memory and the internal memory and stored therein and even when the cassette type memory is removed from the numerical control unit, the stored content can be retained. By repeatedly reading out the command data stored in the cassette type memory, the machine tool can be controlled.
