Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and apparatus for displaying a program created in an NC language in a natural language such as Japanese.

<Prior art and problems to be solved by the invention> Conventionally, numerical control devices (hereinafter abbreviated as NC devices) have been used.
A work program written in NC language is used to give operation commands to the machine.

Therefore, in order to create a work program or modify a created work program, one must be familiar with the NC language.

Specifically, for example, No. N100T060606 N101G53GOOX25.000290.000↓ N102S6N102S6004 N103G54G01G98W-20F250 No. N10

5↓ N109G53GOOX50.000z130゜000
↓ When a work program for N110M30↓ has been created, if it becomes necessary to display the program for modification or the like, the only way is to display the program using the NC language itself.

Also, you can understand the contents of the program by looking at the work program displayed in this way, and if you are familiar with the NC language, the numbers starting with N indicate the block number, block 100 is tool selection, block 101 is Rapid traverse (absolute value command in machine coordinates), 102 starts spindle forward rotation and cutting fluid discharge, 1
03 is cutting feed (relative value command in workpiece coordinates), 104 is left arc (relative value command in workpiece coordinates), 105 is stationary, 1
06 is cutting feed (relative value command in workpiece coordinates), 107 is cutting feed (relative value command in workpiece coordinates), 108 is spindle stop and cutting fluid discharge stop, 109 is rapid feed (absolute value command in machine coordinates), 110 is You can understand that each indicates the end of the program. However, an operator who is not familiar with the NC language cannot accurately understand the contents of the program, and therefore cannot debug or modify the program. That is, even if it is possible to create a work program using symbolic NC or the like even if one does not know the NC language very well, it is not possible to deal with subsequent debugging, modification, etc.

Also, unlike programming languages such as FOTRAN, NC languages are not standardized, so the NC languages may differ depending on the manufacturer, machine, etc., and it is important for operators to know these various NC languages. Not only is it required, but it is also required to know which NC language to use. As a result, the number of operators who can create and modify work programs is considerably reduced, and there is also the disadvantage that a long period of time is required to train operators who can meet these requirements.

<Object of the invention> This invention was made in view of the above problems,
It is an object of the present invention to provide a new natural language display method and apparatus for displaying program contents in a manner that is easy to understand even for operators who are unfamiliar with NC language.

Means for Solving the Problem> In order to achieve the above object, the natural language display method of the first invention is such that a table showing the correspondence between the NC language and the natural language is created in advance, and the NC language Import the program created character by character, divide it into multiple words starting with an alphabetic character and ending with the next alphabetic character or before the line break mark as one word, and compare each division with the NC language in the table.
This method reads out the natural language corresponding to the matched NC language from a table and displays it.

The natural language display method of the second invention is a method of displaying natural language read from a table at a predetermined location.

In order to achieve the above object, the natural language display device of the third invention includes a table in which NC language and natural language are stored in correspondence in advance, and a program created in NC language character by character. An importing means for importing, a character determining means for determining whether the imported characters are English characters or line feed marks, and a word starting with an English character and ending before the next English character or line feed mark and dividing into a plurality of words. It includes a classification means, a translation means for comparing each classification with the NC language of the table and reading from the table a natural language corresponding to the matched NC language, and a display means for receiving and displaying the natural language read from the table. There is.

In the natural language display device of the fourth invention, the table is NC
Languages and display formats are also stored in association with each other in advance, and further includes a reading means for reading out the display format based on the classified NC language, and the display means reads out the natural language read from the table. It is displayed at the corresponding location in the read display format.

Effect> In the natural language display method described above, a table showing the correspondence between the NC language and the natural language is created in advance. Then, the program written in the NC language is taken in one character at a time and divided into a plurality of words, with each word beginning with an English character and ending with the next English character or line feed mark. In this state, each category is compared with the NC language FA in the table from the noteal that matches which of the NC languages in the table, and the natural language corresponding to the matched NC language is read out from the table and displayed. This allows the entire range of programs created in NC language to be displayed in natural language. As a result, even an operator who cannot understand the NC language can accurately understand the contents of the program. Furthermore, even if the NC language differs depending on the manufacturer, machine, etc., this can be easily handled by simply changing the table or the contents of the table.

In the natural language display method of the second invention, the natural language read from the table is displayed at a predetermined location, so compared to the case where the natural language is displayed in the order of the program categories. A remarkable natural language display can be achieved.

In the natural language display device of the third invention, first, the NC
Languages and natural languages are associated in advance and stored in a table. In this state, the program created in the NC language is imported character by character by the importing means, and the character determining means determines whether the imported characters are English characters or line feed marks. Then, based on this discrimination result,
The classification means divides the word starting with an English character and ending with the next English character or line break mark into multiple words, and each division is compared with the NC language in the table by the translation means, and a matching NC language is selected. A corresponding natural language is read from the table, and the natural language read from the table is received and displayed by a display means. As a result, even an operator who cannot understand the NC language can accurately understand the contents of the program. Furthermore, even if the NC language differs depending on the manufacturer, machine, etc., this can be easily handled by simply changing the table or the contents of the table.

In the natural language display device of the fourth invention, since the table stores the NC language and the display format in association with each other in advance, when the natural language is read from the table by the translation means, the display If the format is stored, the reading means reads the corresponding display format, and the display means displays the natural language read from the table at the corresponding location in the read display format. Therefore, it is possible to achieve a display in natural language that is much easier to see than when displaying in natural language in the order of the program sections.

(1. In these cases, the natural language is
Various natural languages such as Japanese and English can be used.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 8 is a schematic diagram showing an example of the front panel of the NC device, which includes a CRT (1) that displays screen selection, menus for function selection, created work programs, etc., a numeric keypad, and cursor keys. Keyboard section including keys, data input keys, etc. and operation amount setting I\
The operating section (3) includes a handle, an emergency stop switch, a power switch, etc.

FIG. 1 is a block diagram showing an embodiment of the natural language display device of the present invention, which includes a table (4) in which NC language and natural language are stored in association with each other in advance, and The import section that imports the program character by character (5
), a character discrimination unit (6) that discriminates whether the imported characters are English characters, line feed marks, program end marks (hereinafter abbreviated as EoF), or other than these, and based on the discrimination results, a Compare the division section that divides the word up to the next English character or line break mark into multiple words with the NC language in Table (4) for each division, and select the natural language that corresponds to the matched NC language. A translation unit [F]) reads out the table (4), and a CRT (1) receives the natural language read out from the table (4) and displays it.
and a control section 00) that repeatedly operates each of the above sections until EOF is detected.

Note that (11) is a program reference memory that stores a program created in the NC language.

FIG. 2 is a diagram schematically showing the contents of table (4).
Japanese expressions are stored in advance in association with each of degrees O3'' to M30. Therefore, this example
This corresponds to the case where a program created in a foreign language is translated into Japanese, which is a type of natural language, and displayed.

An example of a natural language conversion/display device with the above configuration is as follows.

When natural language display is instructed, the program created in the NC language and stored in the program memory (11) is imported character by character from the import unit (5), and the imported characters are English characters, A character discriminator (6) determines whether the mark is a line feed mark, a program end mark (hereinafter abbreviated as EOF), or something else. That is, the character discriminator (6) discriminates all the characters that are sequentially fetched. Therefore, based on the discrimination results for all the characters that are sequentially captured, the classification unit (7)
Divide one line of the program into multiple words, with one word beginning with an alphabetic character and ending with the next alphabetic character or line feed mark. Then, by supplying each classified word to the translation unit (8), it is compared with the NC language in the table (4), and the natural language corresponding to the matched NC language is selected in the table (4).
Read from 4). Therefore, the natural language read from the table (4) is displayed on the CRT (1
), it is possible to display the words in Japanese corresponding to the words of the program created in the NC language. Regarding the above match determination, depending on the type of English character, complete word-by-word matching or matching of only English characters is required, so these requirements are dealt with in the translation section (8). .

In this case, the repeating operation is controlled by the control unit 00) to repeat the above series of processes until the imported character is determined to be a line feed mark, so the program is translated into Japanese and displayed line by line. In addition, since the repetitive operation is controlled by the control unit 00) to repeat displaying the Japanese language on a line-by-line basis until the imported characters are determined to be EOF, the entire program can be displayed in Japanese. can.

For example, when reading one line of program N108M05M09, the program instruction number is 108 based on "N108", and the program instruction number is "MO
Based on the translation results, it is determined that the spindle is stopped based on "S" and that the cutting fluid discharge is stopped based on "MO9°."

As a result, a Japanese display of "(program block number) 108, spindle stop, cutting fluid discharge stop" can be achieved corresponding to one line of program N108MO5MO9.

<Embodiment 2> FIG. 3 is a flowchart showing an embodiment of the natural language display method of the present invention. When natural language display is instructed, the program memory (11
), and in step ■■■, it is sequentially determined whether the imported character is an English character, a new line mark, or an EOF. Then, if it is determined that the captured character is neither an English character, a new line mark, nor an EOF, the process of step (2) is performed again.

Furthermore, if it is determined in step ■ that it is an English character, it is determined in step ■ whether or not it is the first English character, and if it is determined that it is the first English character, step In step (2), this alphabetic character is designated as the first character of the word, and the process in step (2) is performed again. On the other hand, if it is determined that it is not the first character, in step ■, this alphabetic character is designated as the first character of the next word, and the character before this alphabetic character is designated as the last character of the word. Then, in step (■), search the table (4) for an NC language that is equivalent to the obtained word,
In step (2), the Japanese language associated with the searched NC language is read out from the table (4) and displayed, and the process in step (2) is performed again. If the character before the line break mark is determined to be a line break mark in step ① above, in step [phase], the character before the line break mark is designated as the end character of the word, and in step is searched from the table (4), and in step @, the Japanese corresponding to the searched NC language is read out from the table (4) and displayed, and in step ■, the displayed line is line-feeded, and the order of the imported characters is changed. Reset and perform the process in step (2) again.

Furthermore, if it is determined that it is EOF in the above step (■), in step [Yes], the character before EOF is specified as the last character of the word, and in step (2), the character in the NC language equivalent to the obtained word is table (
4), and in step ■, the searched N
The Japanese language associated with the C language is read out from the table (4) and displayed, the order of the imported characters is reset in step (2), and the series of processing is terminated.

Therefore, in the case of this embodiment as well, the program written in the NC language is imported character by character, and the table is searched by dividing it into a plurality of words using English characters as boundaries. Programs created in other languages can be displayed in Japanese.

<Embodiment 3> FIG. 4 is a block diagram showing another embodiment of the natural language display device of the present invention, and the differences from the embodiment of FIG. 1 are as follows.
Instead of table (4), table (4') is used that stores Japanese display format data in association with a specific NC language. Reading unit (1
2), instead of the display section θ), the table (4'
) receives the natural language read out from the reading unit (
12) The Japanese display matte read out by
CR for display in the state applied to the relevant part of the data
The only difference is that the display section (9') that supplies the signal to T (1) is used.

Therefore, in this embodiment, "GOO" to "G
99° Specific NC like “M03” ~ “M2O”
The Japanese display format data is read into the table (4') corresponding to the program step that includes the language, and the display section (9') displays the Japanese corresponding to each word in the Japanese display format. , it is possible to achieve an extremely easy-to-read Japanese display.

Specific example> For example, the Japanese display of the work program shown in Attachment 1 will be as shown in Attachment 2, and the corresponding Japanese will be displayed in predetermined places, achieving an extremely easy-to-read Japanese display. can. Figure 5 (A) is a diagram schematically explaining the Japaneseization of the NC language order of the program, and shows the "fast forward"
, [cutting feed], [right circular arc cutting], [left circular arc cutting], [stay], and [return to origin], respectively. FIG. 3B shows the position assigned to display the Japanese words obtained by translating the words of the program.

As is clear from these figures, if the word positions for Japanese translation are divided into ■~■, then for each position ■~■ where translated Japanese is displayed, For the position @, use the Japanese word for ■ and a numerical value, for the position MO, use the Japanese word for ■ and a numerical value, and for the position it [existence], use ■. For position ■, Japanese for ■ and Japanese for numerical value, for position ■, Japanese for ■, and for position ■, Japanese for position ■. By allocating and displaying the Japanese characters in ■ and the Japanese characters in the numerical values, it is possible to achieve the Japanese display as described above.

<Embodiment 4> FIG. 6 is a flowchart showing another embodiment of the natural language display method of the present invention, and the difference from the embodiment of FIG. 3 is that in place of the processing step In step ■, the Japanese language associated with the searched NC language is read out from the table (4'), and in step @, the Japanese display format data associated with the above NC language is read out from the table (4'). The only difference is that in step (2), a processing step is adopted in which the Japanese language read from the table (4') is applied to the corresponding part of the Japanese display format and displayed.

Therefore, in the case of this embodiment as well, since the corresponding Japanese words are displayed at predetermined locations, it is possible to achieve an extremely easy-to-read Japanese display.

<Embodiment 5> FIG. 7 is a flowchart showing still another embodiment of the natural language display method of the present invention.

As shown in the same figure (A), a word is extracted in step 2, the extracted word is translated into Japanese in step 2, and 1 word of Japanese is displayed in step 2. In step ■, the contents of the buffer are extracted for the next processing, and in step ■, it is determined whether or not it is EOF. If it is not EOF, the process in step ■ is performed again, but if it is EOF, it is Finish the series of processing.

(B) of the same figure is a flowchart explaining in detail the process of step (■), in which one character of the program is read out, and in step (■) it is stored in a buffer,
In step ■■, it is determined whether it is EOF or a line feed code, and if it is determined that it is neither, the program is read for one character in step [phase], and in step ■@■, it is determined whether it is EOF or a line feed code. However, it is determined whether it is a line feed code or an English character, and if it is determined that it is neither, it is stored in a buffer in step (3) and the processing in step [phase] is performed again. Conversely, in step ■@■, EOF1 line feed code,
If it is determined that it is either an English character or an English character, in step (2), the most recently read character is returned to the program memory, and the series of processing is completed. Further, even if it is determined in step (■■) that the code is EOF or a line feed code, the series of processing is immediately terminated.

(C) of the same figure is a flowchart explaining in detail the processing of step ■.In step [Yes], the contents of the buffer are extracted, and in step ■■, it is determined whether it is an EOF or a line feed code, and which If not, the content retrieved from the buffer is compared with the content of table (4) in step ■, and if they match, the content of the buffer is transferred to the corresponding table in step [phase]. Replace it with Japanese and complete the series of processing. Also, in step ■■, EO
F.

Alternatively, if it is determined that it is a line feed code, or if there is no match in step (2), the series of processing is directly terminated.

FIG. 5(D) is a flowchart illustrating the process of step (2) in detail. In step (2), the contents of the buffer are taken out, and in step @ (2), it is determined whether it is an EOF or a line feed code. If it is determined that neither is the case, a display based on the contents of the buffer is performed in step [phase], and the series of processing ends. Also,
If it is determined that it is a line feed code, the display is moved to the next line in step (3), and the series of processing ends.

Furthermore, if it is determined that it is EOF, the series of processing is immediately terminated.

Therefore, in the case of this embodiment, the program is extracted word by word based on English characters, line feed codes, or EOF, translated into Japanese word by word, and displayed. By repeating the series of processes up to ), a program created in the NC language can be translated into Japanese and displayed.

Note that the present invention is not limited to the above-mentioned embodiments; for example, instead of displaying in Japanese, it is possible to translate and display in any natural language such as English, French, Spanish, etc. Natural language can be displayed in any format different from that shown in FIG. 5, and various other design changes can be made without changing the gist of the invention.

<Effects of the Invention> As described above, the first invention divides a program created in the NC language into one word and displays each word by translating it into natural language, which makes it impossible to understand the NC language. Even an operator can accurately understand the contents of a program, and even if the NC language differs depending on the manufacturer, machine, etc., it has the unique effect that it can be easily handled by simply changing the table or the contents of the table.

Since the second invention displays the natural language read from the table in a predetermined location, the natural language display is much easier to read than when the natural language is displayed in the order of program divisions. It has the unique effect of being achievable.

The third invention divides the program created in the NC language into one word and each word is translated into natural language and displayed, so even an operator who cannot understand the NC language can understand the contents of the program. It has the unique effect of being able to be understood accurately, and even if the NC language differs depending on the manufacturer, machine, etc., it can be easily handled by simply changing the table or the contents of the table.

The fourth invention is that the natural language read from the table is displayed at a predetermined location, so it is easier to read the natural language than when the natural language is displayed in the order of program divisions. It has the unique effect of being able to achieve display.
