Abstract

PURPOSE:To easily confirm the executing state of a machining program by setting a window on an interactive screen for the program editing processing and then showing the execution state of the machining program under execution by the program execution processing within the set window in an animation. CONSTITUTION:When an NC sentence is produced, the information on the NC sentence is shown as a background animation. The input data are processed by an interactive processor 31 to obtain a work machining program. The data on this machining program are successively shown on a display device 16 in a background animation. Meanwhile, the work machining program stored in a nonvolatile memory 34 as an NC sentence is also carried out in a machining state of a machine tool 20 and then shown in a foreground animation. This display is possible for the window which is set on the input screen for the interactive data. As a result, the execution state of the machining program can be easily confirmed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an interactive numerical control device.

[0002]

2. Description of the Related Art While executing a machining program to drive and control a machine tool, other machining programs are created / edited, and information about the machining program in the process of creation / editing is displayed on a display screen as an animation. The interactive numerical control device and the interactive screen for creating / editing the machining program switch the screen display to the display screen for simulation, and animate the execution status of the machining program in the execution process on the display screen. Interactive numerical control devices for displaying are already known.

However, in the conventional interactive numerical control device,
It is not possible to animate the execution status of the machining program in the process of execution while the dialogue screen for creating / editing the machining program is selected. Therefore, if you try to animate the execution status of a machining program that is in the process of executing while creating or editing a machining program, the creation and editing work of the machining program will be canceled once and the display screen for simulation will be displayed. In addition to the selective display, there is a problem that the switching operation of the display screen is troublesome and, as a result, the efficiency of creating / editing the machining program is reduced.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art and to carry out the operation without changing the display screen even when performing the work related to the creation / editing of the machining program. An object of the present invention is to provide an interactive numerical control device capable of confirming the execution status of a machining program in the process by displaying an animation.

[0005]

The interactive numerical control apparatus of the present invention creates a machining program in response to an input operation performed by referring to the dialogue screen, and displays information regarding the machining program on a display screen as an animation. A window is set on the dialog screen of the program editing process in the interactive numerical control device that enables the program editing process to be performed and the program execution process for executing the created machining program to drive and control the machine tool in parallel. The above-mentioned object is achieved by providing a window setting means for displaying the execution status of the machining program being executed in the program execution process by animation in the window.

[0006]

When the window setting means is operated while the machining program is being created by inputting with reference to the dialog screen, the window is set on the dialog screen and is being executed in the window at the present time. The execution status of the machining program, for example, the movement trajectory of the tool, the shape of the tool, the cutting state of the work, etc. are displayed in animation.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an interactive numerical control device according to an embodiment.

The processor 11 controls the entire interactive numerical controller according to the system program stored in the ROM 12. ROM12 has EPROM or EEPR
OM is used. SRAM 13 is used as the RAM 13, and various data or input / output signals are stored therein. A CMOS backed up by a battery (not shown) is used for the non-volatile memory 14, and various data once stored are retained as they are even after the power is turned off.

The graphic control circuit 15 converts the digital signal into a signal for display and gives it to the display device 16. A CRT or a liquid crystal display device is used as the display device 16. The display device 16 displays a shape, processing conditions, etc. when creating a processing program in an interactive form.

The keyboard 17 is composed of shape element keys, numerical keys, etc., and necessary graphic data and NC data are input using these keys.

The axis control circuit 18 receives the axis movement command from the processor 11 and outputs the axis command to the servo amplifier 19. The servo amplifier 19 receives the movement command and drives the servo motor of the machine tool 20. These components are coupled to each other by a bus 21.

A PMC (Programmable Machine Controller) 22 receives a T function signal (tool selection command) or the like via the bus 21 when executing an NC program. Then, this signal is processed by the sequence program, a signal is output as an operation command, and the machine tool 20 is controlled.
Further, it receives a status signal from the machine tool 20, performs a sequence process, and transfers a necessary input signal to the processor 11 via the bus 21.

Further, on the bus 21, there are software keys 23 and NC whose functions are changed by a system program or the like.
A serial interface 24 is connected to send data to an external device such as a floppy disk device (FDD), printer or paper tape reader (PTR). The software key 23 is provided on the CRT / MDI panel 25 together with the display device 16, the keyboard 17, and the monitor switch which constitutes a part of the window setting means.

In addition to the processor 11 which is the CPU for NC, the bus 21 is connected with a processor 31 for interaction having a bus 30. ROM 32 on the bus 30,
The RAM 33 and the non-volatile memory 34 are connected.

The interactive data input screen displayed on the display device 16 is stored in the ROM 32. On this interactive data input screen, information relating to the NC sentence, for example, the overall movement trajectory of the tool is displayed as a background animation when the NC sentence is created.
Further, the work or data that can be set by the input screen is displayed on the display device 16 in a menu format. The item to be selected from the menu is selected by the software key 23 arranged at the bottom of the screen corresponding to the menu. The meaning of the software key 23 changes for each screen. An SRAM or the like is used as the RAM 33, and various data for dialogue are stored therein.

The input data is the processor 3 for dialogue.
1 to process a workpiece machining program. The created program data is sequentially background-animated on the display device 16 used interactively. Further, the work machining program stored as the NC sentence in the non-volatile memory 34 is stored in the machine tool 20.
It is also executed when processing by, and the foreground animation is displayed. This foreground animation display can also be performed on the window set on the interactive data input screen, and the foreground animation display was performed only when the display screen for simulation was selected. The configuration differs from the device.

FIG. 2 shows the processing executed by the processor 31 when the interactive data input screen is selected while the actual machining operation is being performed by the machine tool 20 using the machining program already created. It is a flow chart which shows an outline.

When the processor 31 detects that the interactive data input screen is selected during the actual machining operation by the machine tool 20, the processor 31 starts the background editing process for creating the machining program according to the program in the ROM 32. First, the input screen of the interactive data selected by the operator is displayed on the display device 16. FIG. 3 is a diagram showing a display example of the display device 16 when the item of the processing definition is selected as the input screen of the interactive data.

The processor 31, which has started the background editing process for creating the machining program, executes the process relating to the creation and editing of the machining program by the processor 11 in response to the operation of the software key 23 by the operator. This is executed in parallel with the control in the same manner as in the conventional art, and the movement locus of the tool of the machining program in the creation process is displayed as a background animation (step S1, see FIG. 3) to define the end of the background editing process. It is determined whether or not the software key has been operated by the operator (step S2). If the background editing process is not completed, the processor 31 is the processor 11 related to the drive control of the machine tool 20.
It is determined whether or not the foreground processing on the side is completed (step S3), and if the foreground processing is not completed, whether the monitor switch provided on the CRT / MDI panel 25 is set to ON. It is determined whether or not (step S4).

If the monitor switch is set to ON, the processor 31 sets a window on the interactive data input screen according to preset conditions (step S5, see FIG. 4), and the processor 11 executes the window. The drawing data for the foreground animation corresponding to the machining program is read from the non-volatile memory 34 in synchronization with the machining program, and the machine tool 20
The cutting status of the workpiece, the movement status of the tool, etc. are displayed in real time in the foreground animation in conjunction with the actual movement of the tool (step S6).

Thereafter, the processor 31 waits until the editing process for creating the machining program is completed (step S
2) or until the drive control of the machine tool 20 by the created machining program is completed (step S3),
Alternatively, until the monitor switch of the CRT / MDI panel 25 is turned off (step S4), the same processing as above is repeatedly executed, and in parallel with the processing relating to the drive control of the machine tool 20 by the processor 11, Processing related to the creation and editing of the machining program and the background animation display such as the tool motion locus by the machining program in the process of creation are executed in the same manner as in the past (step S1), and the machining executed by the processor 11 is executed. The foreground animation display (step S5, step S6, refer to FIG. 4) for displaying the cutting state of the workpiece, the movement state of the tool, etc. in real time in the window is repeatedly executed in synchronization with the program.

Therefore, when the machine tool 20 is driven and controlled by using the machining program which has been prepared while the editing work for creating the machining program is being executed, the cutting condition of the workpiece and the moving condition of the tool, etc. Even if there is something that you would like to know, like before, once you erase the interactive data input screen, reselect the simulation-specific display screen, and then display the workpiece cutting status and tool movement status, etc. It is not necessary to do so, and the operation efficiency for creating and editing the machining program is greatly improved.

Further, when the window display is disturbed when referring to the interactive data input screen, the monitor switch is turned off once and the processing of steps S5 and S6 is not executed to erase the window. Similarly to the drive control of the machine tool 20, only the input operation related to the creation and editing of the machining program and the background animation display of the motion locus of the tool of the machining program in the process of creation are performed. (Step S1, see FIG. 3). Even when the monitor switch is turned off once, the processor 31 automatically updates the data read address from the non-volatile memory 34 in synchronization with the machining program executed by the processor 11, and therefore, if necessary. When the monitor switch is turned on again, the cutting state of the work and the movement state of the tool at that time can be immediately confirmed by the animation display in the window.

When the processing relating to the drive control of the machine tool 20 is completed before the editing processing for creating the machining program, that is, when the determination result of step S3 becomes true as compared with step S2. After that, the determination process of step S4 relating to ON / OFF confirmation of the monitor switch is not performed thereafter, but in this case, the processes of steps S5 and S6 relating to window setting and foreground animation display are also not performed. Therefore, the window is not displayed on the screen. Therefore, in the editing process for creating the machining program that follows,
The window does not disturb the reference of the dialog input screen.

Finally, when the editing process for creating the machining program is completed and the operator operates the software key that defines the end of the background editing process, the processor 31 executes this determination process in step S2. The operation is detected, and the background editing process for creating the machining program ends.

[0026]

According to the interactive numerical control apparatus of the present invention, a window is set on an interactive screen for performing a processing operation related to the editing of a program, and information about the machining program being executed, for example, a moving locus of the tool and a tool. Since the shapes etc. are displayed as animations in this window, the execution status of the machining program in the process of execution can be easily performed without switching the display screen even when performing work related to creating or editing the machining program. You can check
Program creation efficiency is improved.
