Abstract

PURPOSE:To quicken the program check through simulation, by indicating the write of a waiting command and its release command to a processing program. CONSTITUTION:In the process where a picture of, e.g. tool posts 15, 16 on a display 5 is moved with PROs 1, 2, when the tool posts are awaited with the movement of the video and a button 11 corresponding to the tool post 15 is depressed, a waiting signal MS is changed over and inputted to a control section 10, and the processing program PRO in a program memory 9 is interrupted. Thus, a waiting command MAC is written in a processing process PRCS of the PRO 1 executed with the video of the tool post 15 and the movement of the video is stopped via a simulation control section 7. In releasing the waiting, a release command MKC is written by releasing the button 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a numerical control device used in a four-axis numerically controlled lathe.

In the numerical control device of a 4-axis intermittent value control lathe, certain machining units on both turrets are started at the same time in order to eliminate interference between the two turrets and to maintain machining accuracy. In order to start the process at regular intervals, a waiting command function is provided to command the execution tie-der of the machining unit of the double turret.

Conventionally, waiting commands and cancellation of commands had to be instructed on the program when creating a program, and it was not possible to input a meeting command in the form of modifying a program on the numerical control device side. Ta. However, there have been proposals to check the program quickly and efficiently by simulating the program on the display without actually moving the tool rest, etc., but in such cases, conventional methods cannot be used. If you try to insert and modify a rendezvous command etc. in a program, you will have to re-create all the modified programs and re-enter them into the program. This was a major hindrance at the top.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a numerical control device that can immediately make corrections regarding the waiting of a Canadian program when the program is read or output.

That is, the present invention is constructed by providing a rendezvous instructing means for instructing writing of a rendezvous command and its cancellation command in the Canadian program.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

Fig. 1 is a control block diagram showing an example of a 4-axis numerically controlled lathe to which the present invention is applied, Fig. 2 is a schematic diagram showing a cutting program, and Fig. There is f.

As shown in FIG. 1, the 4-axis numerically controlled lathe 1 has a main controller 2 that constitutes a numerical controller 4.
includes a keyboard 3, a display control unit 6 to which a display 5 such as a cathode ray tube is connected, a seamstress control unit 7, and a machining program program 9 in which a computer program PRO is stored. It continues. SIEMI RESIDENT 11 CONTROL UNIT 7
Adjustment buttons 11, 12 are provided in a manner corresponding to each of the tool rests 15, 16, which will be described later. In addition, the Canadian program memory 9
The two turrets constituting the mechanism section 14 of the lathe l, namely, the first turret 15&' and the second turret 16, are connected to the turret via a turret control section 13 that controls the movement of the turret. .

Since the 4-axis numerically controlled lathe 1 has the above configuration, the operator can input the machine program P before actual machining.
When checking the RO, the keyboard 3 is operated to output the scissor release operation command SC to the main control section 2, and the main control section 2 then operates the scission control section 7.
drive and order the start of shemireshi falsification. The control section 7 immediately reads out the cutting program PRO from the machining program program 9, and displays images 15a and 16a of the two turrets on the display 5 via the display control section 6, as shown in Figure 11!3. It is displayed together with the image 19 of the workpiece in a manner that it is moved according to the cannibal program PRO. In the memory 9, as shown in Figure 2, the Canadian program PR is stored.
O is stored separately for each turret in the form of program PROI for the first turret 15 and program PR02 for the second turret 16, and each program PROI, P
H10 is for each predetermined unit of machining (here, a series of machining operations performed in a temporally continuous manner using the same tool is referred to as a machining process PBC8, and is considered as one machining unit). They are stored in the order of execution starting from the top in the figure. Therefore, the control unit 7 displays the images 151 and 161 of the tool post on the display 5 according to the programs PROI and PH10. Figure 3 Arrow A.

It is moved in the directions B, C, and D, that is, in the main direction and in the direction perpendicular thereto. When the operator recognizes that it is necessary to meet between the tool rests based on the movements of the images 15m and 16a on the display 5, etc., when ordering the meeting to the tool rest to be held, for example, the vs1 tool rest 15, The waiting button 11 corresponding to the tool post 15 is pressed. When the button 11 is pressed, the waiting signal M8 of the button 11 changes from l11 to IQI and is input to the waiting control section 10.

interrupts the Canadian program PR0 in the program program 9, and the video 15a of the tool rest 15 currently displayed on the display 5 is the program program PR0 that is currently being executed.
A waiting command MAC for a predetermined waiting hood, etc. is written on the processing process PRC8 of the OI, and the system 3
4 Stops the operation of the image 15a via the range control unit 7. This causes the image on the display 5 to stop.
5 a also boogram PROI meeting command MAC
A waiting state is entered in the process PRC8 where is written, and during this time the image 16a of the other tool rest 16
continues to move according to program PRO2. As the meeting continues, the operator no longer changes the state of the images 15a and 16a on the display 5.
When it is determined that the waiting state of the tool post 15 should be canceled, the button 11 is stopped being pressed.Then, the signal MS of the button 11 is activated.
returns from 10- to 111, and as a result, the rendezvous control unit 10 issues a predetermined rendezvous cancellation command on the process PRC8 of the cannibal program pB02 that is being executed by the image 1116a of the tool rest 16 when the rendezvous is canceled. At the same time as writing the MKC, the operation of the video 15a is started from the booth PRC8 where the waiting was performed via the transmission control unit 7, and the waiting state of the video 1511 is also released. If you want to command the tool rest 16 to meet up, press the button 12 and do the same thing as above.
A waiting command MAC is written to the program PR02 side, and a cancellation command MKC for canceling the waiting for coughing is written to the program PROl side.

In this way, while simulating the computer program PRO on the display 5, the waiting buttons 11 and 12 are operated to write the waiting command MAC and its release command MKC in the computer program PRO, and the system executes the system execution. Once the program PRO check is completed,
Based on the modified program PRO, the turret control section 13
drives and controls the tool rests 15 and 16 and begins actual machining work. The control unit 13 stops the tool post 15 (or 16) on the side where the command MAC is written when the operator instructs a meeting at the time of sieving and reaches the process PR08 where the meeting command MAC is written. Meanwhile, the other tool rest 16 (or 15) has its own program P.
The process PRC8 of RO2 (or P1'LO1) is executed, and when it reaches the process PR08 in which the release command MKC of the program P R02 (or PROI) is written, the control unit 13 starts the tool rest 15 (or 16). The processing process pncs of the Canadian program PROI (or PRO2) where the waiting was performed
The tool rest 15 (or 16) is operated from.

In the above embodiment, the machining process PR08, which is a predetermined unit of machining, is completely stored in the machine program memory 9 between the program Pf'LO1 of the first tool rest 15 and the program PRO2 of the second tool rest 16. As described above, the process PR08 can be stored in any manner in the memory 9 as long as the turret and the execution order of the process PRC8 are determined. Of course.

As explained above, according to the present invention, the rendezvous command MAC and its cancellation command MKC are sent to the Canadian program PRO.
Since we have provided a waiting instruction means such as waiting buttons 11 and 12 that instruct writing of , it is possible to make corrections regarding the waiting of the machining program 4PRO immediately at the time of starting the scissoring process, which contributes to speeding up the program check. can.
