The display item setting unit 11 has a function of generating an item selection image in which a predetermined plurality of displayable items are displayed in a list, and supplies the item selection image to the display control unit 14. Since the display control unit 14 causes the touch panel 20T to display the item selection image, the user can operate the operation input unit 15 or the touch panel 20T to select a desired display item from the display items displayed in a list form. . Further, as shown in detail later, the display item setting unit 11 also has a function of updating the display setting data D2 when the user operates to instruct the addition or deletion of the video module.

The monitoring image generating unit 12 acquires the image from the main control unit 10 The information specified by the setting data D1 is displayed as information indicating the state of the wire electrical discharge machine 2, and a state image indicating the information is generated. The image module generating unit 13 can obtain the current value of the plurality of display items specified by the display setting data D2 from the main control unit 10, and generate a plurality of image modules respectively indicating the current values (hereinafter only the "module" Said it. Here, the "display item" is an item indicating the state of the electric discharge machine 2 by numerical values, and examples of the display items include "processing speed", "line remaining time", "number of line breaks", and "interelectrode". Voltage". Further, the video module generating unit 13 generates a module group image in which the plurality of modules are arranged in an entire column state and outputs the image to the display control unit 14. The display control unit 14 generates a state monitoring screen for arranging the state image and the module group image in the above-described arrangement. Further, the display control unit 14 displays the state monitoring screen on the image display screen of the display device 20. Further, "screen image" means an image displayed on the entire image display surface 21.

FIG. 2 is a view showing an example of a state monitoring screen displayed on the image display surface 21 of the display device 20. As shown in FIG. 2, the state monitoring screen is composed of a state image 22M displayed on the upper portion of the image display surface 21 and a module group image 22S displayed on the lower portion of the image display surface 21. The module group image 22S is composed of image modules M1 to M7 having the same shape and the same image size. In the module group image 22S, five modules can be arranged along the horizontal direction, and two modules can be arranged along the vertical direction.

Fig. 3 is a view showing a specific example of a screen for state monitoring. The state image 22M shown in FIG. 3 indicates an image of the state of "automatic start" of the wire electric discharge machine 2 to be controlled. In the module group image 22S, the whole column The module M1 indicating the current value of the "machining speed", the module M2 indicating the current value of the "line remaining time", the module M3 indicating the current value of the "number of wire breaks", and the "interelectrode" Module M4 of current value of voltage and modules M5~M7. Here, "machining speed", "line remaining time", "wire break number", and "interelectrode voltage" are display items designated by the setting data D2.

The image module generating unit 13 displays a state monitoring screen displayed between the image display surfaces 21, and when the operation input unit 15 or the touch panel 20T is used to input an operation of the selection module, a display corresponding to the module is generated. A detailed information screen showing the details of the project. As a user operation series for selecting a module, for example, a pressing operation on the pointing device (meaning a button pressing the button of the pointing device once or plural times) or a touch operation on the touch panel 20T (meaning a finger or the like) The operation of the operating body after it touches the screen). When there is such a user operation, the display control unit 14 switches the state monitoring screen displayed on the image display surface 21 to the detailed information screen. Fig. 4 is a view showing an example of a detailed information screen displayed on the image display surface 21 when the user who operates the module M3 of Fig. 3 is operated. As shown in FIG. 4, on the image display surface 21, maintenance information image modules m1 to m11 indicating detailed information on the maintenance of the wire electric discharge machine 2 are displayed. The user can switch the detailed information screen to the original state monitoring screen by operating the operation input unit 15 or the touch panel 20T.

Next, the display control of the numerical controller 1 will be described below with reference to Fig. 5. Fig. 5 is a flow chart schematically showing the steps of the display control process.

Referring to Figure 5, the numerical control device 1 waits until it is processed. The operation input required at the beginning (NO of step ST11). When there is an operation input required for the start of machining, the numerical controller 1 displays the state image 22M and the module group image 22S on the image display surface 21 (step ST12). In other words, when the main control unit 10 detects the operation input, the monitoring image generating unit 12 generates the state image 22M, and causes the image module generating unit 13 to generate the module group image 22S. Next, the main control unit 10 instructs the display control unit 14 to cause the image display surface 21 to display a state monitoring screen including the state image 22M and the module group image 22S. Then, the main control unit 10 starts the machining control (step ST13).

Then, when there is no event regarding the module (for example, a change in the measured value of the processing speed or the like) (NO in step ST14), the display control processing shifts to step ST16. On the other hand, when an event occurs with respect to the module (YES in step ST14), the main control unit 10 detects the event based on the respective monitoring outputs of the mechanical state monitoring unit 35 and the consumables state monitoring unit 36, and causes the image to be modulated. The group generation unit 13 and the display control unit 14 update the display of the module (step ST15). Thereby, the value of the display item shown in the module can be updated to the latest value. For example, in the case of the electric discharge machine 2, since the workpiece WP is gradually processed as shown in the pre-edited program at the start of processing, it is not necessary for the operator to constantly monitor the progress of the processing. However, the operator sometimes wants to check the values of the machining speed, the inter-electrode voltage, or the specific resistance in order to determine whether or not the machining can be performed normally. Therefore, in the present embodiment, the module is updated so that the value of the display item becomes the latest value. Further, in the case of a display item whose value always changes as the processing speed, an event always occurs, and the value of the display item is updated instantaneously.

At the next step ST16, it is determined whether it is useful to select the operation input of the module. When there is no operation input for selecting a module (NO of step ST16), The display control processing shifts to step ST17. At step ST17, it is determined whether or not the processing is completed. When no processing is completed (NO in step ST17), the display control processing returns to step ST14.

On the other hand, when it is determined in step ST16 that the operation input by the selection module is necessary (YES in step ST16), the display control unit 14 causes the image display surface 21 to display the detailed information screen as shown in Fig. 4 (step ST20). Further, when there is no event regarding the maintenance information image module in the detailed information screen displayed (the case of the maintenance information image module m1 to m11 in the case of FIG. 4) (NO in step ST21), the display control processing shifts. Go to step ST23. On the other hand, when an event regarding the maintenance of the information image module occurs (YES in step ST21), the display control unit 14 detects the event based on the respective monitoring outputs of the mechanical state monitoring unit 35 and the consumables state monitoring unit 36. The image module generating unit 13 and the display control unit 14 update the display of the module (step ST22).

In the next step ST23, the display control unit 14 determines whether or not there is an operation input for returning to the original display screen (step ST23). When there is no such operation input (NO at step ST23), the processing returns to step ST21. On the other hand, when the operation input is made (YES in step ST23), the display control unit 14 causes the image display surface 21 to display the state monitoring screen including the state image 22M and the module group image 22S (step ST24), and displays The control process moves to step ST14.

Finally, when there is an operation input required for the end of the machining, or when the predetermined machining program is all completed (YES in step ST17), the main control unit 10 ends the machining control (step ST18).

Next, the processing steps of adding or deleting a module will be described with reference to FIG. Figure 6 is a schematic representation of where the module is added or removed. Flow chart of the steps. The main control unit 10 starts the processing of Fig. 6 when the operation input for setting start is detected. For example, the user selects an item of the displayed operation table by pressing a button of the pointing device, or a long touch operation by the touch panel 20T (meaning that the operating body such as a finger is relatively long The operation of leaving the screen after touching the screen) selects an item of the displayed operation table, whereby the processing of FIG. 6 can be started.

When the process of FIG. 6 is started, the display control unit 14 switches the state image 22M to the item selection image 22K and displays the item selection image 22K on the upper portion of the image display surface 21 as shown in FIG. 7 ( Step ST31). Next, the display control unit 14 displays the displayable items in the item selection video 22K in a list (step ST32). At this time, as shown in FIG. 7, "display item 01", "display item 02", "display item 03", ... are displayed on the image display surface 21 as a displayable item. Fig. 8 is a view showing an example of the displayable items of the wire electric discharge machine 2.

Then, when the operation input of the additional display item is used (YES in step ST33), the display item setting unit 11 changes the registration content of the display setting data D2, and adds the new display item to the existing display item (step ST34). ). At this time, since the video module generating unit 13 generates a new module group image based on the changed display setting data D2, the module group image 22S is updated. As a result, as shown in FIG. 9, the module M7 indicating the new display item is added to the existing modules M1 to M6. On the other hand, when there is no operation input for adding a display item (NO in step ST33), step ST35 is executed.

Then, when it is useful to delete the operation input of the unnecessary display item (YES in step ST35), the display item setting unit 11 changes the display setting amount. The registered content of the material D2 is deleted, and the display item is deleted from the existing display item (step ST36). At this time, since the video module generating unit 13 generates a new module group image that does not include the module indicating the unnecessary display item based on the changed display setting data D2, the module group image 22S is updated. As the user operation performed in this case, for example, after the pointing device of the mouse or the like is used to select an unnecessary display item, the operation of one item of the displayed operation table is selected by pressing the pointing device. Alternatively, an operation of selecting an item of the displayed operation table by the long touch operation of the touch panel 20T may be used to select an unnecessary display item. On the other hand, when there is no operation input for deleting the display item (NO in step ST35), step ST37 is executed.

In step ST37, the display control unit 14 determines whether or not there is an operation input for returning to the original display screen (step ST37). When there is no such operation input (NO in step ST37), the processing returns to step ST32. On the other hand, when the operation input is made (YES in step ST37), the display control unit 14 displays the state monitoring screen including the state image 22M and the module group image 22S on the image display surface as shown in FIG. The upper area of 21 (step ST38).

As described above, in the numerical controller 1 of the first embodiment, a plurality of modules indicating the current values of the plurality of display items indicating the state of the controlled object are displayed on one screen in an aligned state. Therefore, the user can quickly and easily grasp the current state of the controlled object. Further, the user operates the input unit 15 or the touch panel 20T in accordance with a simple procedure, and a new display item is added to the existing display item, whereby the module can be added. Alternatively, the user operates the input unit 15 or the touch panel 20T according to a simple step, and deletes unnecessary display items from the existing display items, thereby deleting In addition to the module. Therefore, the display form of a plurality of modules can be customized quickly and flexibly in accordance with the current state of the controlled object.

Further, the user simply operates the operation input unit 15 or the touch panel 20T, and selects the module to display the detailed information screen as shown in FIG. 4 on the image display surface 21 (step ST20 in FIG. 5). Therefore, the load on the user's monitoring service of the machine to be controlled is reduced.
