Abstract

PURPOSE:To shorten the time generating a part program with a subprogram system by integrally specifying a call part in the subprogram by the part program using automatic programming language. CONSTITUTION:NC data NCP with an execution type is composed of a main program MP and the subprogram SP, and is provided with a subprogram call command 11 and a subprogram end command 12. The part program PPR using the automatic programming language is equipped with a main program MP' and a subprogram SP', and a command 33 instructing a subprogram main body 32, a call command 31 and the end is inserted into the SP' part. Thus, at the time of outputting the conversion of the data NCP, the main part MP1' in the program PPR is sequentially converted into an NC data MP1 with an execution type so as to output. If the command of the program PPR is a call instruction 31, it is converted into a call instruction 11 with an execution type so as to output. Afterwards, data is converted into the data NC of an execution type, stored in a working memory 41 and sequentially converted and outputted.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an NC data output method, and is particularly applicable to Bell's NC system, in which an NC device can execute a t<-dot program created using an automatic programming language. The present invention relates to an NC data output method of converting into data (NC data in executable format) and outputting the data.

<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 (
NC consisting of E I A code or ISO code)
Convert to data.

For example, in creating a part program that moves a tool along a shape consisting of straight lines and circular arcs shown in Fig. 3, first the tool starting point P1, cutting starting point P2, straight lines S1, S2
and arc C1... P=x y P2=x2. y2 P=x, ys=p, p...(1) C1=
X4. y4. rl... (2) P5 = x5 y5 S = P, C, B... (3) Define the figure as follows, and then use these defined points, straight lines, and arcs to create CUTTER, 5 ...(4) TLLFT ...(51F
ROM, P, ... (6) PA
ST, S, P...(7)S
.

By defining INI END and motion statements along the tool path in an automatic programming language and inputting them into the automatic programming device, NC data in executable format in EIA code or ISO code is automatically created and written to NC tape. Output. However, (1) means a straight line passing through points P2 and P3, (2) means an arc with radius r1 at the center (x4°y4), and (3) means a straight line passing through point P5 and touching arc C0. Of these, the lower tangent line (straight line) is indicated, (4) is a tool command that commands a tool with a cutter diameter of 5 mm, (5) is a command to offset the cutter to the left in the direction of movement, and (6) is a command when the starting point is Pl. The command indicating that (7) is the straight line S1
This is a command to position the cutter so that it passes through the straight line and touches the straight line at point P2.

By the way, in such automatic programming, there are cases where it is required to output NC data in subprogram format. Incidentally, the subprogram format NC data is (al execution format NC data (NCP) (7) as shown in FIG. is inserted, and up to the subprogram call instruction, NC is executed by the main program part MPI.
(b) After the subprogram call command, processing is performed according to the commands of the subprogram SP, (C1 subprogram end E2 continues the main program, and in-program part MP2 performs NC control.
This is C data. However, in Fig. 4 (A>) “M2
"O" is the subprogram call 17 instruction, the alphabet '°P'" is the word address word which means that the following numeric character is the subprogram name, "M O
2" is a program end command, and "M99" is a subprogram end command.

Such NC data in subprogram format has conventionally been
As shown in Figure (B), (a) a part program portion MP' corresponding to the main program MP1, and (b) a subprogram call command (MODE).

(C) Part program part MP2' corresponding to main program part MP2 (However, "F I N
I'' is a command indicating the end of the part program), (subprogram part sp' corresponding to dl subprogram SP (however, "MODE, SUB.

Lororo°°, specify the name of the subprogram that follows.
L:l M:/F,” MODE, SUB, END
” is a command indicating the end of a subprogram) is created and inputted to the automatic programming device, and output from the automatic programming device. Note that 1. f = 1, program PPR
If input, the automatic programming device will change MP1' part → MP1 part MODE, CALL, Rororo; →M98. P Rororo;
MP2' portion→MP2 portion MODE, SUB, [[1 mouth; →0 rororo SP' portion-sp portion MODE, SUB, END, →M99; It is converted into NC data in executable format and output.

<Problem to be solved by the invention> As described above, in the conventional method, there is a correspondence between the part program written in the automatic programming language and the NC data in the executable format, as shown by the arrow in FIG. 4(B). After the part program is created, the conversion process can be performed relatively easily.

However, in the conventional part program creation method, a subprogram call command 21 is inserted at an appropriate position in the main part, and the part 1 of the subprogram part is called after the main part 1 to program creation.

It was to generate a program SP'.

For this reason, in the conventional part program generation method, it is necessary to separately designate the calling part 21 and the part SP' of the subprogram, which makes programming cumbersome. In particular, there is a problem in that the longer the block length becomes, or the more subprogram call commands are included in the part program, the more troublesome the programming becomes.

From the above, it is an object of the present invention to integrally -C-cut the part called the subprogram call part in a part program using an automatic programming language.
An object of the present invention is to provide an NC data output method.

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

In Figures 1 (A) and (B), NCP is the executable N
In the C data, MP is the main program and SP is the subprogram 1. M P 1 to MP2 are main program parts, 11 is a subprogram call command, and 12 is a subprogram end command.

Moreover, in FIG. 1(B), PPR is a part program written in an automatic programming language, M P 1 ', MP
2' is the main program part, SF5 is the subprogram part, and 31 is the subprogram call command 1.
32 is the main body of the subprogram, 33 is a command for instructing the end of the subprogram, and 41 is memory (working memory).

Effect> In a part program using an automatic programming language, programming becomes easier if the subprogram call part (31) and the called part (32, 33'l) can be specified together.

Therefore, in the present invention, part program (PPR
) are created in the order of tool motion, and the subprogram call command (3]), subprogram body (32), and SAZOP 1 "grab," command (33) are integrally inserted at appropriate locations in the 1<-do program.

Then, when converting and outputting the executable NC data (NCP), the main part (
MPI') into NC data (MPI) in sequential execution format and outputs it, as well as part program (PPR).
If the command is a subprogram read command (31), the command is executed as a subprogram read command (1).
1) and then outputs the subprogram body (32) up to the subprogram end instruction (33) in the executable format N.
The part program (MP2') is converted into C data and stored in a memo U (41), and after the subprogram end command (33), the part program (MP2') is sequentially converted into executable NC data (MP2) and output.

The memory (41) after the conversion process of all partogolograms
The executable NC data stored in is output as a subprogram (sp) after the already output NC data (MP2) with a program name (0rororo) attached.

<Example> FIG. 2 is a flowchart of the process of the present invention.

Hereinafter, the invention will be explained in detail with reference to FIGS. 1 and 2. It is assumed that the part program (PPR) has already been created. That is, the part program PPR is generated by inserting a subprogram call instruction (31), a subprogram body (32), and a subprogram end instruction (33) in the order of tool movement and at appropriate locations in the part program. shall be.

(1) Sequentially read data or commands of a part program that has already been created and stored in memory.

(2) The processor checks whether the read data is a command (FINI) indicating the end of the part program.

(3) If it is not F I N I, create executable NC data using the read data.

(4) After reading the data read in step (1), the subprogram call command "MODE, SU" is sent.
B.

Check whether it is "n".

(5) If it is not a subprogram call command, the subprogram end” MODE, SUB, END
” Check whether

(6) Next, check whether the data is in the subprogram itself (in the subprogram).

(7) If it is not a subprogram, the NC data generated in step (3) is stored in the NC data storage memory or output to an external storage medium. Thereafter, the process from step (1) onwards is repeated.

As a result of the above, the part program (P
The main program part (MP1') of PR) will be converted into an executable main program part MPI.

...See part 31 of Figure 1 (B) (8) On the other hand, if the data read in step (1) is a subprogram call command, the processor secures an area in the working memory 41 to store the subprogram. .

(9) Thereafter, the tjNC data generated in step (3) is sequentially stored in the working memory 41 until the command indicating the end of the subprogram is read.

As described above, the part program SP' of the subprogram (32) is stored in the working memory 41.・
...Refer to part 82 in Figure 1 (B) [10] Step (5)
), if the read data is a command indicating the end of a subprogram, check whether the subprogram already registered in working memory and the newly created subprogram are the same by comparing the contents of each subprogram. do.

(If there is a Kawamukai subprogram (with subprogram number m), it is assumed that the newly created subprogram is discarded and the same subprogram is called. In other words, it is assumed that m−+n .

Cl2) After that, or if they are not the same in step (10), check whether it is in a subprogram.

If the subprogram is not in the j131 subprogram, the executable subprogram call command "M2S Pn" is stored in the NC data storage memory or output to an external storage medium. ...After referring to part 33 of Figure 1 (B), repeating the process from step (1) onwards,
The main program portion (MP2') of the part program (PPR) shown in ) is converted into the main program portion (MP2) in executable format.

...Refer to part 34 of FIG. 1(B) (X4) If the above processing continues and the command F I N I " indicating the end of the program is read, the processor executes the working, NC command stored in the memory 41. Store data as a subprogram in NC data storage, memory, or output to an external storage medium.・
...Figure 1 (B) With reference to S5, the part program (
PPR) is the NC data (
NCP) and output.

Note that although the above description is a case in which the subprogram body (referred to as the first subprogram body) does not include a subprogram call command, it may also be included. In this case, a state is created in which the subprogram is in progress at the step board (121:.2), and the second subprogram call command is transferred to the first subprogram storage area of the working memory by the processing of the subprogram (I5). M 98 P△△
△″ will be stored.

FIG. 5 is a relationship diagram showing a schematic relationship between a part program PPR, which is more complex than that shown in FIG. 1, and executable format NC data NCP obtained by converting the part program.

<Effects of the Invention> According to the present invention, a part called a subprogram call part is integrally specified in a part program using an automatic programming language, so it is easier to create a part program in subprogram format compared to the conventional method. , can be created in a short time without mistakes.
