Abstract

PURPOSE:To permit the smooth work by allowing the task of an NC instruction calculation routine to use a working calculation routine in common and output only representation data into a separate memory part and executing the color representation on a same picture scene through switching memory position. CONSTITUTION:It is judged if a key for ordinary picture is pushed down or a key for graphic picture is pushed down in the key input processing routine by the input signal supplied from a keyboard, and color representation is performed on a CRT through a buffer in case of the ordinary picture, and while, green representation is performed in case of graphic picture. Therefore, a user can grasp at a glance which data is represented or which data is set. Thus, the work for newly setting a picture scene is avoided, and the need for a user to prepare the new picture scene for graphic reprersentation is avoided, and smooth work can be carried out.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electric discharge machining device, particularly one of its numerical control devices.
This invention relates to an electrical discharge machining device that allows one function to be used as another based on certain rules.

[Conventional technology]

Conventionally, there has been a device of this type as shown in FIG. In the figure, a is the workpiece to be processed, CI is the workpiece (a movable table on which one is placed and fixed, Oe,
(A) is the sliding part, α4), H is the driving motor that moves the sliding part (11, (A), (22) is the driving motor aa
, a control device for controlling as, (24) a wire electrode, (26) a wire supply reel, (28) , (34
) is a power supply unit that supplies power to the wire electrode (24), (30)
, (32) is a wire guide, (3(S) is a tension roller, (38) is a wire take-up roller, (40) is a power source for electrical discharge machining, (42) is a DC power source, (44) is a switching transistor, ( 48) is a charging resistor, (46) is a charging capacitor, (50) is a switching control circuit, (
52) is a machining fluid supply device, (56) is a tank for storing machining fluid, (58) is a resistivity ynm device, (60) is a pump that supplies machining fluid to the machining section, (62) is a nozzle, (5
4) is a processing fluid.

Next, the operation will be explained. The movable table Ql on which the workpiece a is driven is moved in the X-axis direction by the drive motor, and in the X-axis direction by the drive motor (14)K.
The movable table (position 1G is driven by the drive motor (14), (II)
2) The position is controlled by Further, a pulse voltage V is applied between the wire (24) and the edge of the workpiece by a processing power source (40). On the other hand, the machining fluid supply device (56)
The machining fluid (54) whose specific resistance has been adjusted is applied to the workpiece (l
is supplied between the dryer and the wire (24). At this time, the machining fluid (54) flows between the workpiece Q and the wire (24).
Electrical discharge occurs through 'r, and the workpieces 0 to 0 are machined in accordance with the control signal of the control device (22).

In the control device (22), inputs 9 such as the coordinates of the wire (24) and processing conditions are displayed using a CR, T display device, etc.

[Problem that the invention seeks to solve]

Conventional electrical discharge machining equipment is configured as described above.
Display and input could not display two types of commands at the same time. In other words, during machining or during NC operation, the same calculation routine such as other NC commands must be used and displayed on the same display, and for this reason, it must be displayed in a way that the user can understand. Then, there was a problem that it was necessary to have a table, and the display procedure had to be the same.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an electrical discharge machining apparatus that can simultaneously process different NC commands and display different displays during normal work procedures.

[Means for solving problems]

The electric discharge machining apparatus according to the present invention includes a routine (task) that calculates an NC command, and the tasks commonly use a machining calculation routine, output only display data to another storage unit, and switch storage locations. By displaying different colors on the same screen, users can see which task they are working on.

[For production]

In this invention, displaying in different colors is a method of displaying screens that the operator is accustomed to, and a screen that has a second meaning is output.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing the process from the manual input of the keys to the color-coded data display on the CRT. FIG. 2 is a flowchart of the data control routine of FIG. Figure 6 is the first
0 is a more detailed block diagram of the display routine shown in FIG. 0. Next, the operation will be described. Based on the signals input from the keyboard in Figure 1, it is determined in the key manual processing routine whether a normal screen key or a graphic screen key has been pressed, and subsequent key manual processing (data setting, screen selection) will affect only one of the buffers. At the same time, other display data and color data are transferred from the data control routine of FIG. 1 to the display routine shown in FIG. 6, and are processed on the CRT according to the data flow shown in FIG. At this time, the normal screen on the CRT is displayed in color, but the graphic screen is all green, so the user can see at a glance which data is being displayed and which data is being set. You can see it here.

In the above embodiment, switching between the normal screen and the graphic setting screen was performed manually using keys on the keyboard, but the same effect can be achieved by providing a toggle or the like and inputting a signal.

〔Effect of the invention〕

As described above, according to the present invention, since the setting screen is made common and the colors are changed to give different meanings, there is no need to make new settings for the screen, and it is useful for effective use of memory. This also has the effect that the user does not have to learn a new graphic setting screen and can work more smoothly.

[Brief explanation of drawings]

Figure 1 is a data block diagram from key manual input to data being color-coded and displayed in C FIG. 4 is a detailed block diagram of a part of FIG. 1, and FIG. 4 is a schematic diagram of the wire electrical discharge machining apparatus. In the figure, αno is a workpiece, ni and aa are drive devices, and (22) is a control device. Note that the same reference numerals in each figure indicate the same or corresponding parts.
