Abstract

PURPOSE:To reduce an area for storing macros, by treating character strings used in a macro as character-string variables. CONSTITUTION:A microprocessor 1 reads a macro one block by one block from a magnetic bubble memory 4 and stores commanded character strings in a prescribed area of a RAM 3. Then the microprocessor 1 stores a character string which is formed by adding the character string stored in the prescribed area of the RAM 3 to a character string commanded by the current block in another prescribed area of the RAM 3, or stores a character string which is formed by adding a character string commanded by a read block to the character string stored in the prescribed area of the RAM 3 in another prescribed area of the RAM 3. Therefore, the program quantity of a macro which uses numerous character strings, whose parts are common, can be reduced and effective utilization of a memory can be realized.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a numerical control device that can reduce the unique memory area of a macro by treating character strings used in the macro as character string variables. It is something.

[Conventional technology]

When machining is performed in a fixed cycle, the cycle is recorded in memory as a macro in advance.1. Let me go, G6
Conventionally, a necessary macro is called by a block including 5, an argument is specified, and control is performed according to the macro to which the argument is specified.

Macros for processing a rectangle are shown in a~ below.

1--l When the numerical control device reads block β including the above G65, it reads macros a-k for rectangular processing, and then variables #26. I for each #27! x, ly are given, and then a rectangular shape is processed according to maflob ~k. In this way, when machining is performed in a fixed cycle, by pre-registering the cycle as a macro in the memory, it is possible to easily create a carnivorous program.

[Problem that the invention seeks to solve]

However, the conventional example described above has the following problems. The above macro has blocks b, c, e, and f to check if an argument has been forgotten, and also has blocks b, c, e, and f.
A character string is used for f. Furthermore, blocks b and c
are respectively variable #26. If #27 is not specified, this is an instruction to perform the processing of N 100 and N 110, and block e.

[respectively rDATA ERRORXJ, rD
This is a command to display "ATA ERRORY" on the display device. In this way, strings are sometimes used in macros, but in the past, strings had to be directly commanded in macros, so if you wanted to use many different types of strings, you could It is necessary to prepare a macro statement that commands example characters, which causes the problem that the program becomes large and a large amount of space is required to store the macro.

The present invention solves the above-mentioned problems, and aims to reduce the area in which macros are written even when a large number of character strings are used in macros.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention calls a macro by a macro call command, and in a numerical control device that performs control according to the macro, the character string commanded by the registration command in the macro is The storage means described in item 1 and the character string instructed by the addition command in the macro are stored in item 4.
9 Means 1. This is provided with an addition means for adding to the character string that is being written.

Further, FIG. 2 is a flowchart showing part of the processing contents of the microprocessor 1, and the operation of FIG. 1 will be explained below with reference to the same figure.

In addition, the following symbols a-n° show examples of macros for processing a rectangle. Note that these are written in the magnetic bubble memory 4 in 1. a.

When the block is read, macros are read block by block from the magnetic bubble memory 4, and processing according to the flowchart in FIG. 2 is performed. If the microprocessor 1 determines that the block from which SJδ is taken has the format r#9000=(character string) (step S3), it stores in RAM 3 the character string commanded by the block from which Aε is taken. In the predetermined area #A, write 1. Let's do it (Ste.

step S7), if it is determined that the read block has the format r#9000=(character string)+;'' (step S4), a predetermined value in RAM3 is written after the character string commanded by the read block. A character string to which the character string 1.9 written in area #A is added is stored in a predetermined area #B of RAM 3 (step S8), and the read block is r#900.
0 = + (character string)'' (step S5), the character string commanded in the block read after the character string stored in the predetermined area #A of RAM 3 is read. The added character string is stored in a predetermined area #B of RAM 3 (step S9), and the read block is “#”.
If it is determined that the character string has the format 3000=123#9000J (step S2), the character string stored in the predetermined area #B of the RAM 3 is displayed on the display device 5.

For example, the processing contents of the microprocessor 1 will be explained as follows, taking the above-mentioned macros a° to n° as an example.

Following block a゛ indicating the program number, block b
When reading ", the microprocessor 1 reads the string rDATA ERRORJ commanded by the block b" because the block b has the format r#9000=(character string); (step s3). It is stored in a predetermined area #A of RAM3 (step s7), and then block C
(Step Sl). By reading block C', microprocessor 1 determines whether variable #26 is specified (step 510), variable #2
If it is determined that 6 is specified, read the block d", if it is determined that it is not specified, read the block 7ri f
o is read (step SL, 10). If it is determined in step SIO that variable #26 is specified and block d is read, the microprocessor 1 determines whether variable #27 is specified (step 5IO) and reads block d''. If it is determined that it is specified, block g
” to start processing the rectangle (Step 5IO)
, if it is determined that variable #27 is not set, block h' is read (step Sl, 10).

Then, if it is determined in step SIO that variable #26 is not specified and block f is read, the block f has the format r#9000-+ (character string). (Step S5), the microprocessor 1 adds the character string commanded in block f' (X in this case) after the character string (DATA ERROR in this case) stored in the predetermined area A of the RAM 3. Column rD
ATA ERRORXJ is stored in a predetermined area #B of the RAM 3 (step S9). Also, if it is determined in step SIO that variable #27 is not specified and block h' is read, the block h' is r#9000=+
(character string)" (step S5)
, the microprocessor 1 reads the character string (DATA ERROR in this case) stored in a predetermined area of the RAM 3.
R the character string rDATA ERRORYJ, which is followed by the character string commanded in the block h' (Y in this case).
It is stored in a predetermined area #B of AM3 (step S9).

Then, when the processing of block f' or block h' is completed, microprocessor 1 reads block i'. Block i is r # 3000 = 123 # 9
000J format (step S2), the microprocessor 1 reads the character string (in this case rDATA ERRORX) stored in the predetermined area #B of the RAM 3.
” or r DATA ERRORYJ 'I is displayed on the display device 5 (step S6), and the process is ended.

In this way, this embodiment converts the character string rDATA IERRORJ commanded by block b' in the macro into RA
This character string rD is stored in a predetermined area #A of M3.
When specifying a character string that includes ATA ERRORJ as a part, use the character string rDATAE like blocks f' and h'.
Since it is only necessary to instruct the character string to be added to RRORJ, the amount of macro programming can be reduced compared to the conventional example. This is especially effective when using a large number of character strings that have some common parts.

In addition, in the embodiment described above, rDATA ERROR
J is registered and rXJ or rYJ is added, but the character strings to be registered and the character strings to be added are not limited to these.Also, even if multiple types of character strings are registered, Of course it's a good thing.

〔Effect of the invention〕

As explained above, the present invention provides a storage means [embodiment In this case, the predetermined area #A of RAM3] and
Additional command in macro [#9000=+ in the example
(Character string) or #9000 = (Character string) A block expressed in the format of tens] is added to the character string stored in the storage means. This is achieved by performing the processing in step S8.9 on the processor 1), so the amount of macro programs that use a large number of partially common character strings can be reduced, and memory can be used effectively. There are advantages.
