Abstract

PURPOSE:To exactly and easily execute the check of a complicated tool path by displaying stored display data in a display color which is coordinated to a specific display data storage means, when this display data storage means is selected. CONSTITUTION:In order to display a tool path (tool locus) in a different color, a graphic memory in a CRT display device 8 stores display data D31 corresponding to a locus A in the tool path and display data D32 corresponding to a locus B, in a plane memory #3, and a plane memory #1 and #2, respectively. Also, as for a check screen for executing a tool path check, color switching is added to a menu. When a key input corresponding to this color switching is executed, the tool path is displayed by switching a display color. In such a way, a display device which can execute a display by changing a display color of the tool path of a specific part, in the tool path can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device having a function of displaying a tool bus and the like.

[Prior Art] FIG. 3 is a block diagram of a numerical control device having a conventional display device. In Figure 3, (1) is the CPU, (2)
(3) is the memory (RAM) that stores the machine program and tool data, etc., and (3) is the memory (ROM) that stores the machine control program including the tool bus check function.
, (4) is the tape (5) on which the Kanji program is perforated.
), (6) is the operation keyboard,
(7) is an input interface for inputting data manually entered into the CPU (1) using an operating keyboard; (8) is a CRT having a predetermined display screen (8a);
Display device (9) is C that controls the CRT display device (8)
The RT controller (lO) is an output interface that outputs operation commands from the CPU (1) to the machine (11).

The CRT display device (8) has a graphic memory for graphically displaying display data such as material shapes and program shapes. This graphic memory is a device consisting of four brain memories corresponding to each display color so that the display data can be displayed in a specific color.For example, the display data D1 of a cutting edge to be displayed in red is stored in the brain memory H in green. The display data D2 of the material to be displayed in is stored in the Brain Memo January 2, and the display data D3 of the moving trajectory of the cutting edge to be displayed in yellow is stored in the Brain Memory $3.

Similarly, the display data D4 of the axis and display frame is stored in the brain memory 4, the display data D5 of the program shape is stored in the brain memories St and 112, and the display data D6 of the chuck and tail stock are stored in the brain memory! 11 and 03, respectively.

Next, the operation when displaying a tool bus of a Canadian program using a conventional display device will be described.

To display the tool bus of the Canadian program, use the CRT
A check screen as shown in FIG. 3 is displayed on the display screen (8a) of the display device (8). This check screen displays a menu at the bottom and a display frame at the center. When the operator selects a menu using the keyboard (6),
Display data corresponding to the menu is displayed within the display frame.

Note that the tool bus of the cannibal program is displayed either by displaying the entire tool bus at once or by displaying each step of the cannibal program.

[Problems to be Solved by the Invention] By the way, when displaying the tool bus of a Canadian program, the conventional display device with the above configuration draws the tool bus from the start of machining to the end of machining at one time, so for example, three When displaying a complex tool bus such as dimensional cutting, it is very difficult to understand, and there is a problem in that it is difficult to check the part you want to see with particular attention.

The present invention has been made to solve the above problems,
It is an object of the present invention to provide a display device that can display a specific part of a tool bus in a different display color.

[Means for Solving the Problems] The display device according to the present invention has a plurality of display devices, each of which is associated with a specific display color, and which stores display data to be displayed in a specific display color among the display data. display data storage means; selection means for selecting a specific display data storage means from a plurality of display data storage means; and display data stored in the display data storage means selected by the selection means, corresponding to the display data storage means. and display control means for causing the display means to display the assigned display color.

[Function] In the display device having the above configuration, when a specific display data storage means is selected by the selection means from among the plurality of display data storage means, the display control means is stored in the selected display data storage means. Display data is displayed on the display means in a display color associated with the display data storage means.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a display device according to an embodiment of the present invention. Note that in FIG. 1, parts that perform the same functions as those in FIG. 3 are designated by the same reference numerals, and the explanation thereof will be omitted.

In order to display the tool bus (tool trajectory) in different colors, the graphic memory of the CRT display device transfers display data D3 corresponding to trajectory A from the tool bus to the brain memory 83 and display data corresponding to trajectory B. D32 is stored in the brain memory Ill and $2.

Also, on the check screen for performing a tool bus check, color switching is added to the menu as shown in FIG. If there is a keystroke corresponding to this color switching, the display color will be switched and the tool bus will be displayed.

Next, the operation of the display device shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

(1) Step 5l-34 When performing a tool bus check, a check screen as shown in FIG. 1 is displayed. When the tool bus check start key is pressed (step S1), the CRT display device (2) displays the tool bus stored in the plain memory 3 (step S2). Therefore, the toolbus will be displayed in yellow.

In this case, when color switching is manually performed (step S3), the CRT display device (2) displays the brain memory
and display the tool path stored in 廁2. Therefore, the tool bus will be displayed in red or green.

Note that if the color change is manually operated again, the CRT
The display device (2) displays the tool bus stored in the brain memory 113.

Further, the tool path stored in the brain memory II3 and the tool path stored in the brain memory Ill and the fog 2 may be tool paths of the same part,
It may be a tool bus of different parts.

Further, in this embodiment, the case where the tool bus is displayed in different display colors has been described, but it goes without saying that the display colors can be similarly changed when displaying other display data.

[Effects of the Invention] As explained above, according to the present invention, when a specific display data storage means is selected by the selection means from among a plurality of display data storage means, the display control means selects the selected display data. Since the display data stored in the storage means is displayed on the display means in a display color associated with the display data storage means, complex display data, for example, complicated tool paths such as three-dimensional cutting, can be displayed on the display means. This has the effect of providing a display device that can accurately and easily check the following.
