Abstract

PURPOSE:To easily and surely determine a qualifier by displaying all patterns which can be defined without undefined qualifiers on a CRT, and displaying question sentence to ask which pattern is to be defined. CONSTITUTION:When a pattern definition statement with a qualifier undefined is inputted from a keyboard or the like (in a step 11), all of patterns C1-C4 defined by this pattern definition statement are displayed on the pattern display part of the CRT (in steps 12, 15, and 18). Questions to ask which pattern is to be defined are displayed on the question display part of the CRT 8 (in steps 13 and 16). The defined pattern is specified (in steps 14 and 17), and this specified data is used to determine the undefined qualifier in the pattern definition statement. Thus, patterns displayed on the CRT are referred to easily and surely determine the qualifier even if the qualifier is difficult to understand.

Description

[Detailed Description of the Invention] <Industrial Application> The present invention relates to a method for creating an NC part program consisting of a figure definition statement and a motion definition statement created using an automatic programming language. N suitable for determining
This article relates to a method for creating a C part program.

<Prior art> In automatic programming that creates NC data using automatic programming languages such as APT and FAPT, points, straight lines, and arcs are defined using simple symbols (shape definition), and these definitions are A tool path is defined using points, straight lines, and circular arcs (motion statement definition), and a part program is created using an automatic programming language. NC data in the format (
It is converted into NC data consisting of ErA code or rso code.

For example, when creating a part program using a tree automatic programming language by moving a tool along a shape consisting of straight lines and circular arcs shown in Fig. 4, first, the tool starting point P1, the cutting starting point P2, the straight lines S1, S2, and the circular arc C8. ... as PART, ■RE I DA I ...

・01) If you define C1 INI END and the motion statement along the tool path in an automatic programming language and enter it into the automatic programming device Z, the automatic programming device will automatically perform EIA while referring to the NC data output table. Create and output executable NC data using code or 180 code.

However, (1) instructs the start of the part program, and rRE I DA I J is the heading.

(Indicates the type of 21if N Cm, MILL for milling and TURN for turning.
Use. rABsJ indicates an absolute command (INCR is used in the case of an incremental olfactory command).

(3) means a straight line passing through points P2 and P3, and (4
) is a circular arc with center ("4p y4) and radius r1, (5)
means the lower tangent (straight line) of the two tangents that touch the arc 01 through the point P5. However, the alphabet B is a modifier that means below, and in the case of an upper tangent, use the modifier A that means above instead of the modifier 已.

(6) is a tool command that commands a tool with a tool diameter of 10Isll, (7) is a spindle rotation speed command, and (8) is a command to offset the tool to the left in the direction of travel (
However, if the tool is to be offset to the right side in the direction of movement, TLRGT), (9) is a coordinate system setting command indicating that the start point is P, (111 is a command to set the cutter at point P2 without passing through straight line S1). The command for positioning so as to be in contact with a straight line (11) is a speed command indicating that the feed speed is 500 mm/min.

Now, in the above example, only one modifier appears, but
In addition, as shown in Figure 5 (A), 2 of the circle C1 and the straight line S1
The one that specifies one of the two intersection points Pi and P2 (the modifier R is the right point P1, L is the left point P2, A is the upper point P1, and B is the lower point P2).

Specifies one of the four circles that touch 2 (the upper left circle for A and L, the upper right circle for A and R, and the lower left circle for B and L,
The lower right circle is specified by B and R).

<Problems to be solved by the invention> By the way, even for beginners of automatic programming languages or those who know the grammar of automatic programming languages, modifiers in figure definition statements may be difficult to understand, and figure definitions can be troublesome. There was a problem with incorrectly defining shapes.

From the above, an object of the present invention is to provide a method for creating an NC part program that can easily and reliably determine a modifier while referring to a figure drawn on a CRT, even when the modifier is difficult to understand. .

Means to solve problems〉 FIG. 1 is a schematic explanatory diagram of the method of the present invention.

11.14.17 are data input steps, 12°15.
18 is a graphic display step, 13.16 is a large amount display step, and 19 is a modifier determination step.

When a figure definition sentence is input from the keyboard or the like with the word undefined (step 11), all figures C1 to C4 that can be defined by the figure definition sentence are displayed on the figure display section of the CRT ( Step 12゜15.18) Display the size of which figure you want to define on the question size display section of the CRT (
Step 13.16).

Then, identify which shape it is (step 14.17)
, determines undefined modifiers in the graphic definition statement using the identified data (step 19).

<Embodiment> FIG. 2 is a block diagram of an automatic programming device that is an embodiment of the present invention.

101 is a ROM in which loading programs etc. are stored.
, 102 is a processor that performs automatic programming processing;
103 is a RAM. This RAM 103 stores the system program read from the floppy FL, the automatic programming 8-word NC part program input from the keyboard, processing results, etc.

104 is an NC data storage memory for storing finally created NC data in an executable format; 105 is a keyboard; 1
06 is a display device (CRT), 107 is a disk controller, and FL is a floppy disk.

The figure definition method according to the present invention will be explained below with reference to FIGS. 1 and 2.

If you input figure definition sentences sequentially from the keyboard 105 etc.,
The processor 102 determines whether each graphic definition statement contains a "?" character that makes the modifier undefined (see step 11 in FIG. 1).

If "?" is not included, RA the shape definition statement.
The figure defined by the figure definition statement is stored in the M103 and drawn on the CRT 106.

However, if the "?" mark is included, for example, the figure definition statement CI=31. S2,10. ? ,? is input (this figure definition statement creates two straight lines 31
.
(step 12), and display the setting size "Above/Bottom for Sl?" indicating which figure is desired to be defined on the question large display section of the CRT 106 (step 13).

Thereby, the operator refers to the figure drawn on the CRT and inputs whether it is above or below the straight line S1 (step 14). In other words, if it is above, the modifier rA means above.
Enter J, and if it is below, enter the modifier "B" which means below. However, the arrow keys ↑ on the keyboard,
You may also use ↓ to enter the top and bottom. In step 14, it is determined that the figure is on the lower side.

As a result, the processor 102 displays only the 61 (lower) figures C3 and C4 specified with respect to the straight line S1 on the figure display section of the CRT (step 15), and also displays the 61 (lower) figures C3 and C4 identified with respect to the straight line S1 on the figure display section of the CRT (step 15). "Left/Right?" is displayed on the large question display section of the CRT (step 16).

Thereby, the operator refers to the figure drawn on the CRT and inputs whether it is to the right or left of the straight line S2 (step 17). However, if it is right, the modifier rR means right.”
If it is left, the modifier rLJ that means left is input, but it may also be input using the arrow key -1- provided on the keyboard. In step 17, "right" is input.

As a result, only the figure C4 on the specified side (right side) is displayed on the figure display section (step 18).

Finally, modifiers are determined by these input rB, RJ or "↓, →" meaning "bottom, right", and the modifiers replace "?p ?J" in the figure definition sentence (step 19). Note that rB and RJ are modifiers themselves, so in step 19, immediately replace r? and ?J with the modifiers.Also, if they are input using arrows, remember the correspondence between the arrows and the modifiers. Find the modifier from the correspondence table and replace it.

Thereafter, the above process is repeated to input all figure definition statements.

Note that the above is a case where two modifiers are undefined when defining one circle that is tangent to two straight lines 31 and 32, but 1
If only one is left undefined, it will be displayed graphically as shown in Figure 3 (A) and (B).
Enter the left side to determine the modifier. However, Fig. 3 (A)
is an example in which the upper and lower modifiers are undefined, and is shown in Figure 3 (B
) is an example where the right and left modifiers are undefined.

Although the present invention has been described with respect to a figure definition sentence that defines a circle that is in contact with two straight lines, the present invention is not limited to such a case, but can be applied to all figure definition sentences that have modifiers.

<Effects of the Invention> According to the present invention, when a figure definition sentence with an undefined modifier is input, all the figures that can be defined without the undefined modifier are displayed on the display screen, and which figure is displayed. Since the configuration is configured so that the modifier is determined by displaying the amount of data to be defined and having the user specify the shape, even if the modifier is difficult to understand, it can be easily done while referring to the shape drawn on the CRT. Modifiers can be determined reliably.
