DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram of a CNC data management system of the present invention. The external memory 1 is provided with a data storage area 1a in which data such as optional software is stored, and a data status storage area 1b in which the usage status is written. The external memory 1 is attachable to and detachable from the CNC 10 via the connecting means 2. In the selection command means 3 in the CNC 10, data to be added is selected from the data stored in the external memory 1 by a screen operation or the like. In addition, the selection command means 3 also issues a selection command for data that is no longer needed for the data that has been used so far.

The read / write execution means 4 reads the additionally selected data from the data storage area 1 a of the external memory 1 and writes it in the internal memory 5. In addition, the unnecessary data is read from the internal memory 5, and the data storage area 1
Write to a. The data status recording means records in the data status storage area 1b the data name read from or written to the external memory 1, its date, the number of times of use, and the like.

FIG. 2 is a block diagram of hardware of a numerical controller (CNC) for implementing the present invention. The processor 11 controls the entire numerical controller according to the system program stored in the ROM 12. here,
A flash ROM is used as the ROM 12, and optional software can be added. RAM
An SRAM 13 is used to store various data. The non-volatile memory 14 stores a machining program, parameters and the like, and is backed up by a battery C.
Since a MOS or the like is used, its contents are retained even after the power of the numerical control device is cut off.

The graphic control circuit 15 converts the data such as the current position of each axis and the movement amount stored in the RAM 13 into a display signal and sends it to the display device 16, which displays it. As the display device 16, a CRT, a liquid crystal display device or the like is used. The keyboard 17 is used to input various data and operate screens. Further, like the keyboard 17, the software key 16a is also used.

The axis control circuit 18 receives a position command from the processor 11 and outputs a speed command signal for controlling the servo motor to the servo amplifier 19. Servo amplifier 19
Drives the servo motor by amplifying this speed command signal.

When a PMC (Programmable Machine Controller) 22 receives a command for M function, S function, T function, etc., it decodes this command by a sequence program and outputs an output signal for controlling the machine tool 20. Further, it receives a limit switch signal from the machine side control circuit 18 or a switch signal from the machine operation panel, processes it by a sequence program, and outputs an output signal for controlling the machine side. Further, signals required by the numerical control device are transferred to the RAM 13 via the bus 21 and read by the processor 11.

An adapter 32 is connected to the bus 21, and the memory card 3 is connected via this adapter 32.

A selection command is given by the operation of 7. That is, the option software name is displayed on the screen of the display device 16 and the cursor 17 is designated by the keyboard 17.

The optional software for which the selection command has been issued is sent to the ROM 12 via the bus 21 and written therein. At this time, the usage status such as the name or number of the added option software, the date, and the number of times of addition is recorded in the data status storage area 1b in the memory card 31.

On the other hand, unnecessary basic software or optional software stored in the ROM 12 is read from the ROM 12 by selecting and instructing the screen operation as described above.
It is returned to the memory card 31. The usage status such as the name or number of the software written in the memory card 31, the date, and the number of times the software is stored is
It is recorded in the data state storage area 1b.

In this way, the memory card 31 storing the optional software is handed over to the user in advance,
By making it possible to copy only what is needed and storing the usage state in the memory card 31, it is possible to periodically check the type of software used, the number of times of use, and the like. Then, if a fee is charged according to the usage state, it is possible to save time and labor for a person on the maker side to go out and work each time the optional software is added.

Although the memory card 31 is used as the external memory 1 in this embodiment, another memory such as a floppy disk may be used. Further, the storage device provided on the maker side and the CNC 10 on the user side may be connected via a communication line to notify the data state in real time.
