Abstract

PURPOSE:To facilitate scaling and shorten the scaling time by displaying a mark as the criterion on a display graphic and expanding or reducing this mark to input scale information. CONSTITUTION:Scale information is inputted to an input device 11 and is transferred to a central processing unit 12 and is transferred to an arithmetic controller 14 through an input controller 13. The arithmetic controller 14 reads information in a storage device 15, and the calculation result is transferred from a display device controller 16 to a display device 17 and is displayed as graphic data. A mark 7 which is displayed in the case of input of scale information 4 is formed on the display screen of an NC device and is expanded or reduced. In the case of scaling, the mark 7 as the criterion is first displayed on the display screen. This mark 7 is expanded or reduced thereafter to allow an operator to easily imagine a designated display picture.

Description

[Detailed description of the invention]

[Industrial Application Field] This invention relates to a numerical control device (hereinafter referred to as C device), and relates to scaling for display figures. [Prior Art] @Figure 4 shows the hardware configuration of a conventional NOC device. This is a part of the figure. In this figure, the input device α receives input of scale information and transfers it to the central processing unit a2. In the central processing unit @, it is sent via the input device controller 0 to the arithmetic and control unit!! Information is transferred to αc.
The data is transferred to the display device α via 9. The display device αη has a device V that takes in the graphic data and displays the graphic. FIG. 5 shows, in the hardware configuration diagram of FIG. 4, that scale information is input from the input device 1itQ11X+) to the central processing unit @ to perform processing associated with updating the scale value.
It is a diagram showing a method of outputting the result to a display device αη. In Figure 5, (1) is the display frame, (2) is the click...
Ping frame, (3) is the final processed shape (display shape), (4)
is scale information indicating the scale on the screen, (5) is the newly input scale value, and (6) is the scale value updated and 1
This is the final processed shape (displayed figure) after this. Traditional display'
W! The scale information of the single figure displayed on the screen is input as a numerical value. The length indicated by this numerical value is displayed on the display graphic so that it is the same length as the line segment (4) indicated by the scale information. That is, the length of each line segment of the displayed figure is obtained by converting the actual length of the line segment using the following equation. (Length of the line segment after scaling of the displayed figure) = (actual length of the line segment) If the scale value is increased, the displayed figure will be reduced, and vice versa (If the ζ scale value is decreased, the displayed figure will be enlarged. [Invention] [Problems to be Solved] Scaling of displayed figures in conventional NO and H filters is performed using a urn, as expected.However, scaling information must be entered numerically, making it difficult for operators to accurately scale. There is a problem in that it is difficult to input the scale value of 1. This invention solves the above problem. , an object of the present invention is to obtain an I'llC device that allows an operator to easily associate the state of a displayed figure after scaling, thereby facilitating scaling. ] When the HeC device according to the present invention scales a display figure displayed on the figure display device,
A reference mark is displayed on a display figure, scale information is input from Cζ to enlarge or reduce the mark, and the figure is displayed based on the scale information. [Function] This invention

[In ζ, when scaling,
Display a reference mark on the displayed figure. After scaling, the operator specifies the solid part of the display that falls inside the reference mark fζ by enlarging or reducing the square mark. In this way, how much to enlarge or reduce the display figure (η) (Since the scale value 1 is determined, it is easy to imagine a display figure that is enlarged or reduced by 1. The embodiment will be explained using FIG. 1, FIG. 2, and the fourth factor. FIG. (6) are completely opposite to those with the same symbols in the above conventional device. (7) is a square mark that is displayed when inputting scale information, and (8) is an enlarged mark. The hardware configuration is substantially the same as the conventional one. Figure 2 is a flow chart explaining the operation of the NOC device which is an embodiment of the present invention. !11
~ (to) indicates each step of the operation. Although it is possible to enlarge or reduce a displayed figure depending on scaling, we will discuss the case of scaling down. Reduction is performed by enlarging the square mark (7). In other words, the enlarged figure within one mark is reduced to fit within the reference mark. First, the operator presses the key to update the snowmaking 0 old ζ scale value. The central processing unit (6) that inputs that information is a graphic display!
(7) By sending a command to the graphic display device α, the power is
As shown in the figure (&), a square mark (7) serving as a reference is displayed on the display figure (Stellib 22). At this time, the size of the mark (7) is constant to the turtle, and the display position a"t'r
aligns the center of mark (7) with the display center. The center of the square mark (7) is always made to coincide with the Eζ display center even when the mark (7) is enlarged or reduced. Next, the operator presses the reduction mode key on the input device (Step 23), and depending on the input mode, it is determined whether the enlargement is a reduction force (in this embodiment, it is determined to be a reduction).
(Step 24), enlarged square mark (8)
Central processing unit to display! Calculate the display position It of tQ2 and output it to the graphic display device αη as graphic data (
Stain knob 26). The graphic display device αη first erases the already displayed mark (7) (Step 25)
. Next, an updated mark (8
) is displayed (Step 27). C No. 11 J (bl) and t.
- Repeat the operation of ``pu@'' until the mark (8) is enlarged to the thickness desired by the operator, and then the operator presses the setting key provided on the input device (6). By this central processing unit! Termination information is input to taz (Stellab 28). Next, in the central processing bag 02 is the input mark/
From the change in size in 7 (8), use the following formula to set the new scale value (Ste Tsubu 29), Length of the horizontal side of the square mark on the melon: l Square after change Length of the side next to the mark: 14 and #X ([Current scale value = (updated 1 scale value)...
・(2) Next, calculate the length of each line segment of the displayed figure by using the equation (2), update the γ, update the scale value, and substitute it into the newly input scale value of the equation (υ). and scaling is performed (stave 80).The graphic display device α is updated to a new value and a figure is displayed on the screen as shown in FIG. 1(C) based on the scale value number ζ (stave 1131).
. At this time, the scale value updated at the same time is used as the scale information (4
). To enlarge by 1, press the enlarge mode key and reduce the square mark (7).If all other evening crops are reduced, it is the same as 6 (Step 21~
24. Step 32.34.85゜Stay 1128~8
1). In other words, the reduced figure is enlarged so that it fits within the reference mark. In the above embodiment, a square mark (7) is displayed on the display figure, and the scale 1212 is performed by enlarging or reducing this mark (7), but since it is a square mark)
Other marks that can be used as a guide, such as H:, -=
, “E, ya Kai゛” etc., and enlarge this mark.
A similar effect can be expected by inputting scale information color by reduction and performing scaling 6. Furthermore, in the above embodiment, when the square mark is enlarged or reduced, the mark of the original size disappears, but the mark of the original size may be left as a reference, and the same effect as in the above embodiment can be obtained. FIG. 8 shows another embodiment in which the original size square mark (7) is displayed with a broken line, and it is enlarged and displayed with a single square mark (8) and a solid line. In FIG. 8, the original size mark and the enlarged mark L are distinguished by broken lines and solid lines. This is to make it easier to distinguish which mark is the reference original size mark when both marks are displayed at the same time.In addition to the solid line and broken line, the distinction is made by color. It's okay. [Effects of the Invention] As described above, according to the present invention, a mark is displayed as a guide on the displayed figure, and scale information is inputted by enlarging or reducing the mark to perform the scaling 1212. , the operator can intuitively know the state (size) of the displayed figure after scaling before scaling.Therefore, there is an effect that τ scaling can be done easily and in a short time.
