Abstract

PURPOSE:To edit and correct a program under high working property and to operation apparatuses accurately by editing and correcting the program by a display device, specifying a block to be executed in the program on the display and interrupting the operation mode by the specified block. CONSTITUTION:At step 505, a display for a program appears on a CRT. In case of edition, the program is a blank sheet of paper, and in case of correction, a registered program is accessed. At step 507, block No. ''001'' and a block number to be corrected are accessed at the edition and correction respectively. At step 509, prescribed programming is executed to form the corresponding block. When a data input key is depressed, data are registered at a step 515. Execution decision at step 519 inquires whether the registered block is to be executed or not. When a cycle start switch, a start key, is depressed at step 519, the block is executed at step 521 by interruption processing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for editing and correcting a program in a numerical control device that allows editing and correcting a program while operating the device.

BACKGROUND ART Conventionally, a numerical control device C has been provided with a so-called editing mode for editing and modifying a program, and a so-called operation mode for actually operating the device automatically or manually.

In the former editing/correction mode, only editing or modification of the program can be performed, and in the latter operation mode, in principle, only the operation of the equipment can be performed.

However, there arises a need to directly execute programs that are being edited, edited, or modified. In other words, for example, an industrial machining machine is used as a machine tool.
When creating a program for diagonal feeding, you may want to execute the program block by block during editing, rather than executing the edited zologram, and perform programming while observing the I'hot operation.

Also, for example, if you run the edited brocrum C hot above and find out that there is a defect related to the moving whistle in a part of the brocrum, you can move the zo 1 cock where the defect exists to the above-mentioned -bot. There are cases where you want to make corrections while observing the operations in steps 1 to 1.

In a case like the above example, conventionally, the created program had to be switched to operation mode and executed from the beginning. Having to go back to the editing correction mode mentioned above to perform programming, the work efficiency is poor, and it is difficult to create a block diagram after observing the actual operation in order to improve the operational accuracy of the device. It was difficult.

In view of the above-mentioned prior art, the present invention allows programming (programming after observing the actual operation of the device) to be performed with good workability, and also enables the user to easily detect some defects in the program while observing the actual operation of the device. The purpose of this invention is to provide a program editing and correction method for a numerical control device that can be modified and also improve the operating accuracy of the Motsu-U 1m instrument.

To achieve the above object, the present invention uses a display device to edit and modify a program, and also specifies a block to be executed in the program on the display, and runs the specified block. This is a program editing/correction method for a numerical control device that is characterized by interrupting the mode and causing immediate execution.

Therefore, in the above configuration, it is possible to execute each block while editing and correcting the program, so that the program that is adapted to the actual operation of the device can be edited and corrected with good work efficiency, and the program that can operate the device with high precision. Editing and corrections can be covered.

Hereinafter, this invention will be described in detail in Section 1j by way of example.

FIG. 1 shows a schematic block diagram of the numerical control state.

ROM3, RAM5, D via pass line 1.

The CPU 9 connected to the module 7 and the like can control the position control module 11 via the serial I1013 and can communicate with the CRT controller 15 via the serial I1017. The equipment motor M is the amplifier 19.
A movement command signal is received from the position control module 11 via C.

In addition, the position detection signal of the coater F attached to the motor M is fed back to the position control module, and the speed detection signal of the tacho generator attached to the motor M is fed back to the amplifier 19. The CII 'T' controller 15 is equipped with a CRT 21 and an MDi manual data input 1 to a voice device 23 to display appropriate numerical control status and issue commands. This configuration allows for

As shown in detail in FIG. 2, the MDi device 23 has a keyboard section 25 and an operation section 27. The keyboard section 25 is
It has a numeric keypad, alphanumeric keys, and other keys, which are not shown in the figure because they are the same as those commonly used for energization. The operation section 27 is a mode selection switch 2
It also has a cycle start switch 31. The mode selection switch 29 is used to select an edit correction mode, a memory operation mode, an arp operation mode, an MDi mode, a handle feed mode, an incremental feed mode, a jog feed mode, and an equal volume mode.

→Normally, the cycle start switch is only used to perform cycle operation, but in this example, if you press this cycle start switch when modifying the program, the operation mode for the specified block will be activated. It handles interrupts so that it can only run for one block.

In addition, the MDi equipment 23 is provided with a feedbold switch 33 for stopping automatic operation, a fast-forward switch 35, a jog for each axis, an incremental switch 37, and three handles for manual pulse generation. There is. In addition, there are also a single block switch 41 for stopping automatic operation after completing a block, an optional block skip switch 43, a dry run switch 45 for operating only the program, a home return switch 47, an overwrite switch 49 for fast forwarding, A switch 51 is provided to determine the incremental feed rate. Furthermore, this release, an emergency stop button 53, a lock selection switch 55 for machine lock and display lock, a manual absolute switch 57, a feed rate override selection switch 59, a jog feed rate 3g IR switch 61, and a handle axis selection switch for the three handles. 63. Similarly, a magnification selection switch 65 is provided to determine the pulse generation rate when the handle 39 is operated.

Figure 3 shows a schematic diagram of the operating system. In the figure, the diagonal arrows indicate the flow of information with the beriferal, the thick arrows indicate the flow of information, and the thin arrows indicate the flow of information with the semaph A.
It shows communication by.

A sutus register 67 for transmitting and receiving emotional signals, an NC file 69 for storing programs, and a motion data section 71 for temporarily storing movement data to devices are present in the RAM 5 shown in FIG. The communicator 73 for the CRT controller 1 is a conversation section with the CRT controller 15: the communicator 7 for position control.
5 is a conversation part with the position control module 11. Management 77 comprehensively manages the operating state. Note that the numbers in the circles shown in the figure correspond to the flow of the operation sequence.

The program block at which the cursor C3R displayed on the UCRT 21 is located is executed when the mode selection switch 29 shown in FIG. 2 is in the editing mode and when the cycle start switch 31 is pressed. There are rules. That is, as shown in FIG. 4, when the above conditions are met, an interrupt signal is generated from the CRT controller 15, and the routine skips to the E'j interrupt routine IR.

Therefore, operating system O8 is
The execution contents are sent via the RT controller communicator 73 to yJ! Accordingly, a predetermined execution should be carried out through the managers 1 to 77 (conversation with the position control communicator 75).

An example of the editing process is shown in the flowchart of FIG.

15. Figure 6 is in edit correction mode (Pull CRT,
FIG. 3 is an explanatory diagram for explaining the display and operation status of the MDi device. Step 503 indicates that the display mode on the CRT 21 is set to program editing/correction mode. This command is issued by a display mode selection signal from the keyboard shown in FIG. Step 505
A program display will appear on the CRT 21. At this time, when editing, the program is a blank slate, and the cursor 79 automatically points to block number 001, but when editing, it is necessary to
A registered program is called.

In step 507, when editing, generally the block number OO1 address is called, and when modifying, the block number to be modified is called. In step 509, predetermined programming is performed to create and overwrite the corresponding block. Therefore, if the data input key is suppressed, the data registration process is performed in step 515 unless the user selects ``Touchi'' in step 513.

The execution determination in step 517 is to ask whether the block after registration is to be changed.

When editing, it is preferable to execute one block at a time from the device origin position. Also, when making modifications, the execution of the corresponding block will be avoided. Please note that when making this correction,
Whether the operation of the device to be pulled is set to absolute value 1 and operated from the origin device, or from the origin position by incremental stitching, or from the end point of the block one block before the block to be executed. Since it is free to set or operate, in this example, it is assumed that the device operates incrementally from its current position. Therefore, the sixth
As shown in Figure CRT 21, if you position the cursor C8R at address 003 of the block ``'' and press start key Cycle Star 1~Switch 31 with u1 up 519, the interrupt 98 process shown in Figure 4 will occur. Step 521
Then, the above block 003 will be executed.

In step 523, it is determined (117i) that the program editing or modification work is finished.The completed program is a program that takes into account several actual operations of robots, etc.

In addition, as shown in FIG. 4 (P4 interrupt conditions are as described above, the present invention is not limited to these examples. (Of course, it is also possible to provide a - switch and -C, or to use other idle keys. Also, in this example, the case where the mode selection switch is set to the flux blocking mode will be explained. (However, for example, when operating manually in MDi mode, it is also possible to send a program change interrupt signal to the edit correction mode side to change the program. It can be widely applied to editing or modifying.

As explained above, the present invention uses a display device to edit and modify a program, and also specifies l and -z blocks to be executed in the program by, for example, moving a cursor. Since there is a method C for editing and correcting programs for numerical control devices, which is characterized by causing specified blocks to be executed immediately, it is possible to easily create programming after observing the actual operation of the device. It is possible to improve the operating accuracy of the equipment.
