DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a numerical control device having a processing program editing function.

(Prior art) To create a machining program, an operator can edit the machining program by adding, modifying, or deleting the machining program according to predetermined operating procedures using an operation panel connected to the numerical control device. This is done by manually entering the machining program into the numerical control device from the keyboard.

FIG. 6 is a block diagram showing an example of a conventional numerical control device, in which the display screen (hereinafter referred to as CRT) la on the operation panel 1 used by the operator to input data and edit machining programs is shown. It is controlled by the CR7 display control section 2. A machining program editing command issued by the operator from the operation panel 1 is sent via the data bus 3 to the CPU 4, which controls all operations within the numerical control device, and then sent via the data bus 3 to select the editing program. Selection of a machining program to be sent to the control unit 5 and to be edited is controlled. The edited machining program name or the edit machining program name or edit from the machining program storage device 7 is sent from the edit program selection control unit 5 to the machining program large output control unit 6 by the edit machining program name or the edit machining program transfer request command or write request command. Input/exit of machining programs is controlled. The editing processing program retrieved from the processing program storage device 7 is temporarily stored in an editing buffer 9, and editing processing such as addition, modification, deletion, etc. of the editing processing program held in this editing buffer 9 is performed. It is controlled by the program editing control section 8. Then, as shown in FIG. 8, the edited image display data of the page with the cursor display indicating the editing position taken out from the editing buffer 9 is transferred to the screen display buffer 11, and the edited screen display data is transferred via the data bus 3. The process of transferring the data to the CRTla is controlled by the machining program display control unit IO.

In such a configuration, an example of the operation of the editing program selection control unit 5, which is the main part, will be explained with reference to the flowchart in FIG. If the machining program editing command is an editing start command, it is checked whether the machining program name is specified (step 5142). If a character string is entered manually after the editing start command, it is determined that a machining program name has been specified, and if the machining program name is "*" (step 5143), the machining program is Step 51: Display all machining program names held in the storage device 7 on the CRTla.
44) Have the operator select the cursor processing program to be edited from among them.

When the "Write/Execute" key on operation panel 1 is pressed by the operator (step 5145), the name of the machining program that was indicated by the cursor at this point is determined as the editing target, and the name of the edited machining program is changed to the name of the edited machining program. A transfer request command for the relevant editing/machining program is sent to the machining program output control unit 6 (step 5146).

On the other hand, in step 5142, if no character example has been entered manually after the editing start command, it is determined that no machining program name is specified, and the machining program name 'A, MIN' is added to the formula (step 5147). , if the machining program name is °'A, MIN '" or "*"
If not (step 5143), the name of the machining program is determined to be edited, and a transfer request command for the corresponding edited machining program is sent to the machining program output control unit 6 (step 5148).

Then, in response to the editing/machining program transfer request command in step 5141i or step 5148, it waits for the editing/machining program to be sent from the machining program output control section 6 (step 5149), and transfers the sent editing/machining program to the machining program. When the data is transferred to the editing control unit 8 (step 5150), the processing at the start of editing is ended.

On the other hand, in step 5141, in the case of a machining program editing command or an editing end command, the machining program edited by the machining program editing control unit 8 and held in the editing fan 9 is returned to the machining program storage device 7 again. Therefore, a transfer request command for the machining program is sent to the machining program editing control unit 8 (step 5151).
At the same time, a write request command for the machining program is sent to the machining program output control section 6. Then, wait for the machining program to be sent from the machining program editing control section 8 according to the machining program transfer request command (step 5152), and then step to transfer the sent machining program to the machining program output control section 6. 515
3) Terminate the processing at the end of editing.

(Problem to be Solved by the Invention) In the numerical control device described above, only the machining program to be edited can be displayed on the CRT. The disadvantage was that it was not possible to edit while referring to the .

(Means for Solving the Problems) The present invention relates to a numerical control device having a function of editing a machining program, and the above object of the present invention is to or specified by the machining program name indicated by the cursor on the display screen among the machining program names of all machining programs in the machining program storage device displayed on the display screen of the operation panel. a selection control unit that selects a machining program from the machining program storage device; and a selection control unit that superimposes the selected machining program on the display screen on which the machining program being edited is displayed based on the position of the cursor on the display screen. This is achieved by including a display control unit that displays the information at the same time.

(Function) In the present invention, the machining program desired by the operator out of all the stored machining programs is superimposed on the machining program being edited and displayed on the same screen. It is possible to efficiently edit a machining program while referring to the program.

(Embodiment) FIG. 1 is a block diagram showing an example of the numerical control device of the present invention in correspondence with FIG. 7, and the same components are given the same reference numerals and the explanation will be omitted. The machining program simultaneous display command issued by the operator from the operation panel 1 is sent to the data bus 3.
is once input to the CPU 4 via the data bus 3.
The information is sent to the simultaneous display program selection control section 12 via the above, and the selection of machining programs to be simultaneously displayed is controlled.

Reading of the simultaneous display section nib program from the machining program storage device 7 is controlled by a transfer request command for the simultaneous display section nib program sent from the simultaneous display program selection control section 12 to the machining program input/output control section 6. The simultaneous display section program taken out from the processing program storage device 7 is temporarily stored in the simultaneous display program buffer 13, and the simultaneous screen display data taken out from the simultaneous display program buffer 13 is transferred to the simultaneous screen display buffer 15. , its simultaneous screen display data and screen display buffer 11
The simultaneous display control section 14 controls the process of transferring the edited screen display data retrieved from the CRTla via the data bus 3.
