2. Description of the Related Art An NC program in a numerical control device is composed of a plurality of blocks described according to a machining order of a workpiece. Each block is composed of a sequence number word used as an index for locating a specific position on the tape, a data word described later, and an EOB (End of Block Character) indicating the end of the block. In this data word, a preparatory function word (G code) that indicates the type of control function in the block, a dimension word that indicates the movement amount or coordinates of the motion of each axis of the machine, and the workpiece and tool during cutting. A feed function word (F code) that specifies the relative speed, a spindle function word (S code) that specifies the rotational speed of the spindle, a tool function word (T code) that specifies the tool number in a machine with a tool change function, and There is an auxiliary function word (M code) as a command for executing various operations of the processing machine.

The auxiliary function word (M code) includes various codes established by JIS. For example, M00 is a program stop, M01 is an optional stop, and M0.
2 is end of program, M03 is main spindle positive rotation, M0
4, spindle reverse rotation, M05 spindle stop, M07 coolant (coolant) start command, M09 coolant stop command,
M10 is a clamp-on command, M11 is an unclamp-on command, M30 is an end-of-tape (indicating the end of the main program) command, M98 is a subprogram calling command, M99 is an end-of-subprogram (returning to the main program) command, and the like. Further, in the M code, a safety door ON, for example, M20 provided for each processing machine,
There is a safety door OFF as M21.

The state of such M code changes according to the execution of the NC program. There is a case where it is desired to confirm the state of the M code after finishing the machining by the predetermined NC program and before starting the machining by the new NC program, or when the machining machine has an abnormality. In such a case, in order to confirm the state of the M code executed by the NC program,
The operator observes the state of the machine corresponding to each M code, or causes the operator to display the bit state of the M code stored in the data area of the address corresponding to each M code on the CRT screen from the storage unit. The state of the M code was observed and the state of the M code was confirmed.
If you want to change the M code status after checking the M code status, switch the NC mode and change the M code status manually or write the M code command in a new program. Was being performed.

[0005]

In the above-mentioned method of confirming the state of the M code according to the prior art, the operator needs to classify the M codes into groups and grasp them, and it takes time to confirm them. If it is necessary to change the state of the M code after checking the state of, the NC mode must be switched to perform a manual operation, or the M code must be written in a new program and executed. There is a problem that time is wasted.

In view of the above-mentioned problems, the present invention reduces the confirmation time of the state of the M code, and the manual operation of the M code is CR.
An object of the present invention is to provide a numerical control device which is operated by key input while watching a display screen such as T.
