Abstract

PURPOSE:To edit and generate an NC part program with high efficiency just in a single time of execution by integrating a correcting operation itself into a part program. CONSTITUTION:The corrected sentences 13-15 are provided and a corrected sentence indicating part 12 indicates the corrected sentences that are carried out before and after those sentences 13-15. An original part program part 11 is converted into a 1st NC part program and a 1st corrected sentence 13 indicated by the part 12 is executed for correction of an original part program part. Then the corrected part program is converted into a 2nd executing NC part program. Hereafter the part 11 is corrected by the corrected sentences 14 and 15. Thus a part program is obtained and then converted into an executing NC part program for output. The correcting operations are integrated into the part program so that plural executing results are obtained just in a single time of execution.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is an N method for modifying an original part program created in an automatic programming language, converting the part program into an executable NC part program, and outputting it.
Regarding the O part program ff4 method.

<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 Define the tool path using points, straight lines, and circular arcs (movement definition!l), create a part program using an automatic programming language, and (b) create an automatic program using the NC data output table. A part program written in a programming language is converted into NC data consisting of NC data (EIA code or ISO code) in a format that can be executed by an NC device.

For example, when creating a part program that moves a tool along a shape made up of straight lines and circular arcs as shown in FIG. ss,,S

If you define INE PEND and the motion statement along the tool path in an automatic programming language and input it into the automatic programming device, the automatic programming device will automatically convert it into EIA code or ISO code while referring to the NC data output table. Create and output an executable NC part program. Note that in the above, line numbers are attached to each figure definition statement and motion definition statement, but these are omitted. Also, P.E.
ND means part program end.

By the way, in one original part program created using an automatic programming language, the first, second,..., nth
There is a case where it is desired to obtain NC part programs of the first to nth executable formats that have been modified. In such a case, conventionally, the first modification is made to the original part program using the keyboard, the first modified part program obtained by the appropriate position modification is converted into the first NC part program in executable format, and then the original part program is similarly modified. Make a second modification to the part program, convert the second modified part program obtained by the appropriate position modification into a second NC part program in an executable format, and thereafter obtain the n-th NC part program in the same manner. I have to.

To delete, press the Delete key and enter the line number you want to delete; to add, press the Insert key and enter the definition statement to be added and its line number; to make corrections, press the Alter key. This is done by inputting the line number and definition sentence of the definition sentence to be corrected.

<The problem that the invention is trying to solve> However, by modifying the part program from the keyboard in this way,
The conventional method of repeating the procedure of converting the corrected part program with the appropriate position correction into an executable NC part program and outputting it requires n times of work, which is troublesome, and it is difficult to convert all n NC part programs. There was a problem in that efficiency was low because the operator was restricted until the product was obtained.

From the above, the present invention provides an efficient NC part program generation method that can obtain execution results for the number of edges (n NC part programs) in one execution by incorporating the modification work itself into the part program. The purpose is to

Referring to step 101 in FIG. 6 above, the original part program 11 is converted into an executable first NC part program (step 103), as in the conventional method.

After the conversion is completed, the commands of the correction statement directive 12 are executed in sequence. That is, the command (1) counts up vl, and the judgment statement (2) checks whether 1=1. In this case, since v1=1, the process jumps to sentence number Δ (steps 105 and 107).

Since the statement number Δ does not have PEND and the first modified statement 13 is arranged, the modification by the first modified statement 13 is applied to the original part program 11 to create the first modified part program and the RAMIO3 working memory 10
3a (steps 109, 111).

When the modification by the first modified sentence 13 is completed, the jump command ``Jump, OJ'' jumps to sentence number 0, and from then on, the first modified sentence q stored in the working memory 103e is
Convert the program into an executable NC part program (
Step 113).

After the conversion of the first modified part program is completed, the command of the modified statement instruction statement 12 is executed again. In other words, both the command (1) counts up vl and (V1=
2) Check whether V1=1 from judgment statement (2) d. In this case, since v1≠1, the following judgment sentence (3
), thereby checking whether ■1=2, and since V1=2, it jumps to the statement number (step 105
．． 107).

Since there is no PEND in the statement number opening and the second modified statement 14 is placed, the correction by the second modified statement 14 is applied to the original part program 11 to create the second modified part program and the RAMIO3 working memory 10
3e (steps 109, 111).

When the modification by the second modification statement 14 is completed, the jump command "Jump, OJ" jumps to statement number ○, and the second modification part program stored in the working memory 103e is then converted into an executable NC part program (
Step 113).

After the conversion of the second modification part program is completed, the command of the modification statement instruction statement 12 is executed. That is, the command (1) counts up vl and (V1=3)
, Judgment statement (2) determines whether v1=1 or not, Judgment statement (3)
Check whether v1=2. In this case, V
Since 1=3, the jump command rJUMP jumps to the statement number (steps 105 and 107).

The statement number is rPEND indicating the end of the part program.
J has been inserted, and the process ends.

<Effects of the Invention> According to the present invention, by incorporating the correction work itself into the part program, multiple execution results (
n NC part programs) can be obtained and NC part programs can be edited and generated efficiently.
