The key device 11 and the CRT 12 are arranged on the same operation panel 21, as shown in FIG. The key manual device 11 includes function keys 22 as specific keys "Fl" to "F8" arranged adjacent to the lower side of the CRT 12, an emergency stop button 23 arranged below the function keys 22, A key mode switching switch 28 as a mode switching means for switching the function key 22 to a specific mode different from the normal mode.
, mode selection switch 24 and spindle speed selection switch 25, alphabetic keys 26 and numeric keys 27.
, and other keys, switches, etc. required for a normal NC device are provided.

The function key 22 commands a predetermined function that is fixedly set in advance in the normal mode, but when switched to a specific mode by the key mode changeover switch 28,
It commands the function set arbitrarily depending on the mode.

The mode selection switch 24 selects a mode provided in a normal NC device, for example, "8UTOJ rMANUALJ".
Used to select rsTORE J, etc.

The storage unit 13 includes a ROM 16 and a RAM 17.

The ROM 16 stores various preset programs. In addition to the storage area provided in a normal NC device, the RAM 17 also stores each of the function keys 2.
2, a key definition area 18 and an index storage area 19 are provided.

The CPU 14 executes R based on the command from the key human power device 11.
Various data are displayed on the CRT12 according to the program stored in the OM16, and the I/O15+ ~
157 to control various drive systems of the machine tool. Further, the operating procedure data and index data from the key manual device 11 are written into the key definition area 18 and index storage area 19 of the RAM 17. moreover,
When the key mode changeover switch 28 is switched to a specific mode, the contents of the index storage area 19 are displayed on the CRT 12 in correspondence with the function keys 22, and the key mode changeover switch 7 is switched to the specific mode. When any function key 22 is pressed in the
The content corresponding to the pressed function key 22 is read out from among 8 and the processing according to the content is executed.

Next, the operation of this embodiment will be explained.

First, each function key 22 is placed in the key definition area 18.
Set the operation procedure data to be performed. This includes:
When the mode selection switch 24 is switched to ``R5TORE'', the display screen of the CRT 12 changes to that screen, so while looking at that screen, input the operation order data to be set to each function key 22 one by one. (see figure). Finally, when a key giving a store command is operated, the data set on the screen of the CRT 12 is stored in the key definition area 18.

Similarly, while looking at the screen of the CRT 12, index data representing operation procedure data set for each function key 22 is sequentially input (see FIG. 4) and stored in the index storage area 19.

Here, when switching to the specific mode by operating the key mode changeover switch 28, the CPU 14 selects the index storage area 19 according to the flowchart shown in FIG.
The index data set in the index is read out, and index data for one key is displayed at a position corresponding to the function key 22 of the CRT 12. Then, the data of other index keys is sequentially displayed on the CRT 12, and 8 keys are displayed (see Figure 6).

In this state, each function key 12 of the CRT 12
Since the index is displayed at the position corresponding to
The operator can select the function key 12 while looking at this index.

Therefore, erroneous operations can be prevented.

Here, when any of the function keys 12 is pressed, the CPU 14 reads the address of the pressed function key 22 according to the flowchart shown in FIG. 7, reads one instruction from the key definition area 18 of this address, and Determine whether the instruction is executable. If it is not executable, it outputs an alarm, but if it is executable, it executes the instructed command and executes all commands in sequence.

Therefore, according to this embodiment, the key definition area 18 is provided in the RAM 17 corresponding to the function key 22, and when any of the function keys 22 is pressed while the key mode changeover switch 28 is switched to a specific mode, Since the operation procedure data corresponding to the pressed function key 22 is read out from the key definition area 18 and executed, if a series of operation procedure data desired by the operator is written in the key definition area 18 in advance, Thereafter, it is only necessary to press the function key 22, so the manual key operation can be simplified without increasing the size of the manual key device 11.

In addition, an index storage area 19 is provided in the RAM 17, and when the key mode selector switch 28 is switched to a specific mode, the contents of the index storage area 19 are displayed on the CRT 12 in correspondence with each function key 22. If index data indicating the operation procedure set for each function key 22 is stored in the index storage area 19, the order of operation performed by each function key 22 will be displayed, making it easy to select the key. In addition, incorrect input can be prevented.

In the above embodiment, the key definition area 18 and the index storage area 19 correspond to the function key 22.
However, a key definition area 18 and an index storage area 19 may be provided corresponding to one arbitrary key or all keys.
