Abstract

PURPOSE:To rapidly and easily perform the definition of a concentric circle by defining the concentric circle based on the code of a numeric value when the numeric value is designated with a defined concentric circle at the time of defining the concentric circle. CONSTITUTION:When the numeric value (r) is designated with a circle (defined circle) C0 which becomes an origin at the time of defining the concentric circle C1, the graphic of the concentric circle C1 with a radius larger than that of the defined concentric circle C0 by the numeric value (r) is defined when a positive code (+) is attached on the numeric value (r). When a negative code (-) is attached on the numeric value (r), the graphic of the concentric circle C1 with the radius smaller than that of the defined circle C0 by the numeric value (r) is defined. Also, when no code is attached on the numeric value (r), the circle C1 concentric to the defined circle C0 with the radius of numeric value (r) is defined.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a concentric circle definition method, and more particularly to a concentric circle definition method for graphically defining concentric circles using predefined circles.

<Prior art> In automatic programming that creates NC data using automatic programming languages such as APT and FA I).

(a) Define a point, straight line, and lining using a simple fl symbol (figure definition), and define a tool path using these defined points and a straight line and 9 circular arcs (motion statement definition). Create part programs using automatic programming language.

(b) NC data in a format that allows the NC device to execute a part program using an automatic programming language (
Convert to NC data consisting of EIA code or ISO code).

In the graphical definition of circles in such an automatic programming system, concentric circles may be graphically defined using predefined circles. In such cases, conventional methods include (1) defining concentric circles by inputting a radius difference value;

(2) There were two ways to define concentric circles, one by inputting a radius value, and the other by inputting a (]-) half-radius value. This is a method of specifying a circle, a radius difference, and the size of the radius difference.

Then, as shown in Fig. 4(a), the radius is the original circle C
If rl is larger than O, the definition statement CI = CO + r 1 + I is created by the above specification, and the concentric circles are graphically defined, and as shown in Figure 4(b), the radius is smaller than the original circle CO by C2. If the above specification is smaller, the definition statement c2=co, r2+ S is created and the concentric circles are graphically defined. In the definition sentence, the alphabet rlJ is a modifier meaning large, and "S" is a modifier meaning small. (2) Defining concentric circles by inputting a radius value is a method of specifying a circle and a radius value that become one element in the radius value input mode, and as shown in Figure 4 (c), the radius value is C3. When defining a circle concentric with the circle CO, the definition statement C3=CO,C3 is created by the above specification, and the concentric circle is graphically defined.

<Problems to be Solved by the Invention> By the way, when defining the shape of concentric circles, in the conventional method, (1) concentric circles by inputting a radius difference value and (2) concentric circles by inputting a radius value are defined by completely different statements. was. Also, the conventional (1).

The operations in the two concentric circle definitions in (2) are different, and in the concentric circle definition method by inputting the radius value in (2), 1
I had to specify whether the circle was larger or smaller than the original circle. This poses a problem in that the work of defining concentric circles becomes complicated.

From the above, it is an object of the present invention to provide a method for defining concentric circles that allows the work of defining concentric circles to be performed easily and quickly.

Means for Solving the Problems> FIG. 1 is a schematic explanatory diagram of a concentric circle definition method according to the present invention.

C1 is the concentric circle to be defined, co is the source circle, and r is a numerical value.

<Operation> When defining the concentric circle C1, when a numerical value r is specified together with the base circle (defined circle) CO, if the numerical value r has a positive sign, the radius of the defined circle CO is Figure 1 (
a)), if the numerical value r has a negative sign -, then the concentric circle C has a radius smaller than the radius of the defined circle CO by the numerical value r.
1 as a graphic definition (Figure 1 (b)), and if the numerical value r has no sign, define a circle C1 concentric with the defined circle CO whose radius value is the numerical value r (Figure 1 (C)). ).

In the tablet device 13, 13d is a tablet surface;
13b is a menu table, and 13c is a tablet cursor. A menu table 13b is pasted on the tablet surface 13a, and various items and data can be input by picking predetermined items written on the menu table 13b with the tablet cursor 13C. By moving the tablet cursor 13c on the tablet surface, the graphic cursor GC8 on the display screen is moved.

FIG. 3 is an explanatory diagram of the main part of the menu table 13b.

3a of the "Circle Definition Column" 3 is the "Concentric Circle Definition" item.

Next, a concentric circle definition method according to the present invention will be explained.

Note that, prior to processing, a system program for defining a figure from the floppy FL is stored in the RAM 11c.

Is it possible to directly input the coordinates of the shape of the circle that is the source of the concentric circles using the tablet device 13° keyboard 14a?

Or define it by quoting the figure drawn on the north side of the display screen CR'r. The defined figure is stored in RAM11c
The data is stored in the memory and drawn on the display screen CRT.

When defining concentric circles from the state where the original circle has been defined,
The operator selects the "Concentric Circle Definition" item 3a from the menu table +3b shown in FIG. Then, a question prompting the circle 11 (which is the source of the concentric circles) is displayed, and the graphic cursor GC8 is cursed on the screen.

Therefore, the operator selects the circle CO (second
When the user places the graphic cursor GC8 on and picks it, the processor Ila displays a question for inputting a numerical value to specify the radius of a concentric circle.

Next, the operator selects "+r" to define a concentric circle with a radius larger than r, "-r" to define a concentric circle smaller than six radii r, and "r" to define a concentric circle with radius r. ” is input from the keyboard 14a according to the question sentence. As a result, if the input numerical value r has an IF sign (+), the processor lla (see Fig. 1)

Also, if the input value r has a negative sign (-) (Fig. 1(b)), then r.
A concentric circle C1 with a smaller radius (r, -p) is defined by the definition statement C1=C0, -r (2) and stored in the RAM 11c.

Furthermore, if the input numerical value r has no sign (Fig. 1 (e
)), a circle C1 concentric with the circle CO whose radius value is the numerical value r is defined by the definition statement CI = GO, r... (3) and stored in RAM, 11 c. 7. In addition, drawing, etc. When performing graphical processing, the processor lla uses the definition statement of the source circle CO and the definition statements (1) to (3) described above to determine the radius of the center of the concentric circles and performs drawing and other graphical processing. conduct.

<Effects of the Invention> According to the present invention, when defining concentric circles, when a numerical value is specified together with a defined circle, if the numerical value has a positive sign, the radius of the defined circle is less than the radius of the defined circle. If a concentric circle with a large radius difference is graphically defined, and the numerical value has a negative sign, a concentric circle with a radius difference smaller than the radius of the defined circle by the numerical value is graphically defined, and the numerical value has a sign. If not, the configuration is configured to define a circle that is concentric with the circle that has been defined for navigation using the radius value, so the concentric circles can be defined more quickly and easily, and as a result, the shape can be defined. The creation time of NC data created using sentences can also be shortened.
