Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method and an 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, a work program created in an NC language has been used to give an operation command to a numerical control device (hereinafter abbreviated as an NC device).

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

More specifically, for example, N100T060606 ↓ N101G53G00X25.000Z90.000 ↓ N102S600M07M03 ↓ N103G54G01G98W-20F250 ↓ N104G03W-20.000I0K10.000F180 ↓ N105G04U7 ↓ N106G01W-20.000F250 ↓ When the work program of ↓ has been created, if it is necessary to display the program for correction etc., the only way was to display the program in the NC language itself.

Also, you can understand the contents of the program by looking at the work program displayed in this way.If you are familiar with the NC language, the number starting with N indicates the block number, block 100 is tool selection, 101 is tool selection. Rapid traverse (absolute value command in machine coordinates), 102 starts spindle forward rotation and cutting agent discharge, 103 feeds cutting (relative value command in work coordinates), 104 left arc (relative value command in work coordinates), 105 stops , 106 is cutting feed (relative value command in work coordinates), 107 is cutting feed (relative value command in work coordinates), 108 is spindle stop and cutting agent discharge stop, 109 is fast feed (absolute value command in machine coordinates), 110 Indicates the end of the program respectively. However, an operator who does not know the NC language very well cannot understand the contents of the program accurately, so that there is a disadvantage that debugging and modification cannot be performed.
In other words, even if a work program can be created by a symbolic NC or the like without knowing the NC language very well, subsequent debugging and correction cannot be dealt with.

Also, unlike programming languages such as FOTRAN, NC languages are not unified, so NC languages may be different for different manufacturers, machines, etc., and operators may be aware of these various NC languages. Not only is it required, but you also need to know which NC language to use. As a result, the number of operators who can create and modify work programs is greatly reduced.
There is an inconvenience that it takes a long time to train operators who satisfy these requirements.

<Object of the Invention> The present invention has been made in view of the above problems, and a novel natural language display method and apparatus for displaying the contents of a program so that an operator unfamiliar with the NC language can easily understand. It is intended to provide.

<Means for Solving the Problems> In order to achieve the above object, a natural language display method according to a first aspect of the present invention is to prepare a table indicating a correspondence between an NC language and a natural language in advance, The program created in step 1 is read one character at a time, starts with an alphabetic character, and divides it into multiple words with one word up to the next alphabetic character or before the new line mark. In this method, a natural language corresponding to the NC language is read from a table and displayed at a predetermined location.

In order to achieve the above object, a natural language display device according to a second aspect of the present invention includes a table for storing an NC language, a natural language, and a display format in association with each other, and a program created in the NC language. A capturing means for capturing one character at a time, a character discriminating means for determining whether the captured character is an English character or a line feed mark, and a plurality of words starting with an English character and extending up to the next English character or a new line mark as one word. Classifying means, reading means for reading the display format based on the classified NC language, and translation means for comparing the NC language in the table for each category with a natural language corresponding to the matched NC language from the table And a display means for receiving the natural language read from the table and displaying the natural language at a corresponding position in the read display format.

<Operation> In the case of the above natural language display method, a table indicating the correspondence between the NC language and the natural language is created in advance. Then, a program created in the NC language is fetched one character at a time, and is divided into a plurality of words, starting with an English character and ending up to the next English character or a line feed mark as one word. In this state, since each section matches any of the NC languages in the table, each section is compared with the NC language in the table, and a natural language corresponding to the matched NC language is read from the table and is predetermined. By displaying the program at a predetermined location, the entire range of the program created in the NC language can be displayed in the natural language. As a result, even an operator who cannot understand the NC language can correctly understand the contents of the program. Even if the NC language differs depending on the maker, machine, etc., it can be easily dealt with by simply changing the table or the contents of the table.

Further, it is possible to achieve a natural language display which is remarkably easy to see as compared with the case where the display is performed in the natural language in the order of the program division.

In the natural language display device according to the second invention, first, NC
The language, the natural language, and the display format are stored in a table in association with each other in advance. In this state, the program created in the NC language is fetched one character at a time by the fetching means, and whether or not the fetched character is an English character or a line feed mark is determined by the character determining means. Then, based on the result of the determination, the dividing unit divides the word into a plurality of words starting with an alphabetic character and ending up to the next alphabetic character or a line feed mark as one word, and dividing the word into a plurality of words by the reading unit.
Reads the display format based on the language, compares it with the NC language of the table by the translation means for each section, and matches
The natural language corresponding to the NC language is read from the table, the natural language read from the table is received, and the display unit displays the natural language at a corresponding position in the read display format. As a result, even an operator who cannot understand the NC language can correctly understand the contents of the program. Even if the NC language differs depending on the maker, machine, etc., it can be easily dealt with by simply changing the table or the contents of the table.

Further, it is possible to achieve a natural language display which is remarkably easy to see as compared with the case where the display is performed in the natural language in the order of the program division.

In these cases, various natural languages such as Japanese and English can be adopted as the natural language.

<Example> Hereinafter, an example will be described in detail with reference to the accompanying drawings.

FIG. 8 is a schematic diagram showing an example of a front panel of the NC unit, a CRT (1) for displaying a menu for selecting a drawing and a function, a created work program, etc., a numeric keypad, a cursor key, and a function. It includes a keyboard section (2) including keys, data input keys, and the like, and an operation section (3) including an operation amount setting handle, an emergency stop switch, a power switch, and the like.

FIG. 1 is a block diagram showing an embodiment of a natural language display device according to the present invention. The table (4) stores an NC language and a natural language in association with each other in advance, and a table created in the NC language. Capture unit that captures programs one character at a time (5)
And a character discriminating unit (6) for discriminating whether the fetched character is an English character, a line feed mark, a program end mark (hereinafter abbreviated as EOF) or any other character. Division unit that divides up to a word before the English character or new line mark into multiple words (7)
And a translation unit (8) that reads the natural language corresponding to the matched NC language from the table (4) by comparing with the NC language of the table (4) for each section, and a natural language read from the table (4). It includes a display unit (9) that receives and supplies it to the CRT (1) for display, and a control unit (10) that repeatedly operates the above units until EOF is detected. (11)
Is a program memory for storing programs created in the NC language.

FIG. 2 is a diagram schematically showing the contents of a table (4), in which Japanese expressions are stored in advance in association with NC languages "G00" to "G99" and "M03" to "M30". is there. Therefore, this embodiment corresponds to a case where a program created in the NC language is translated and displayed in Japanese, which is a kind of natural language.

The operation of the natural language display device having the above configuration is as follows.

When the natural language display is instructed, the program created in the NC language and stored in the program memory (11) is fetched character by character from the fetch unit (5).
The character determining unit (6) determines whether the fetched character is an English character, a line feed mark, a program end mark (hereinafter abbreviated as EOF), or any other character. That is, the determination by the character determination unit (6) is performed for all of the characters that are sequentially captured. Therefore, based on the determination results of all the characters sequentially taken in, the division unit (7) starts with an alphabetic character and extends one character before the next English character or a line feed mark.
The program of one line is divided into a plurality of words as words. Then, by supplying each segmented word to the translation unit (8), the word is compared with the NC language of the table (4), and a natural language corresponding to the matched NC language is read from the table (4). Therefore, by supplying the natural language read from the table (4) to the CRT (1) via the display unit (9), the display in Japanese corresponding to the words of the program created in the NC language can be performed. Can be. Regarding the match determination, since a complete match in word units is required according to the type of English character, or a match only in English character is required, the translation unit (8) deals with these requests. .

In this case, the repetitive operation is controlled by the control unit (10) to repeat the above series of processing until the captured character is determined to be a line feed mark. It can be displayed, and the repetition operation is controlled by the control unit (10) to repeat the display in Japanese one line at a time until the captured character is determined to be EOF. Can be displayed.

For example, when the program N108M05M09 for one line is read, the program instruction number is 108 based on “N108”, the spindle is stopped based on “M05”, and the cutting is performed based on “M09”. The fact that the ejection of the agent is stopped can be determined based on the result of the translation. As a result, Japanese language display of "(program block number) 108, spindle stop, cutting agent discharge stop" can be achieved corresponding to one line of program N108M05M09.

<Embodiment 2> FIG. 3 is a flowchart showing an embodiment of a natural language display method according to the present invention. When a natural language display is instructed, a program memory (1
One character of the corresponding program is fetched from 1), and in a step, it is sequentially determined whether the fetched character is an English character, a line feed mark, or EOF. If it is determined that the fetched character is not an English character, a line feed mark, or EOF, the step processing is performed again. If it is determined in the step that the character is an English character, it is determined whether or not the character is the first English character in the step. If it is determined that the character is the first English character,
In the step, this English character is designated as the first character of the word, and the process of the step is performed again. vice versa,
If it is determined that the character is not the first character, in this step, this English character is designated as the first character of the next word, and the character before this English character is designated as the last character of the word. Then, an NC language equivalent to the obtained word is searched from the table (4), and in a step, Japanese language associated with the searched NC language is read out from the table (4) and displayed, and the process of the step is performed again. If it is determined in the above step that the character is a line feed mark, in the step, the character before the line feed mark is designated as the end character of the word, and in the step, it is equal to the obtained word.
The NC language is searched from the table (4). In the step, Japanese language corresponding to the searched NC language is read out from the table (4) and displayed. Reset, and the process of the step is performed again. Furthermore, if it is determined in the above steps that EOF,
In the step, the character before the EOF is specified as the last character of the word, and in the step, the NC language equivalent to the obtained word is searched from the table (4), and in the step, the NC language is associated with the searched NC language. Japanese is read out from the table (4) and displayed, and the order of the fetched characters is reset in a step, and the series of processing is ended as it is.

Therefore, also in this embodiment, the program created in the NC language is fetched one character at a time, and the table is searched by dividing the table into a plurality of words with English characters as boundaries. Programs written in a language 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. The difference from the embodiment of Fig. 1 is that a specific language is used instead of the table (4). The use of a table (4 ') in which Japanese display format data is stored in advance in association with the NC language, and the provision of a reading unit (12) for reading the Japanese display format data from the table (4') , Instead of the display unit (9), receives the natural language read from the table (4 ′), and displays it in a state where it is applied to the corresponding portion of the Japanese display format data read by the reading unit (12). for
The only difference is that the display unit (9 ') for supplying to the CRT (1) is used.

Therefore, in the case of this embodiment, "G00" to "G9
9 ”, and reads out the Japanese display format data into the table (4 ′) corresponding to the program step including a specific NC language such as“ M03 ”to“ 30 ”, ), The Japanese corresponding to each word is applied to the corresponding portion of the Japanese display format, so that the Japanese display that is extremely easy to read can be achieved.

<Specific Example> For example, the Japanese language display of the work program shown in the separate table 1 is as shown in the separate table 2, and the Japanese language corresponding to the predetermined location is displayed, so that the Japanese language display that is extremely easy to read can be achieved. . FIG. 5 (A) is a diagram schematically illustrating the conversion of a program into NC languages in the order of NC language.
“Cut feed”, “Right arc cutting”, “Left arc cutting”, Stop, and “Return to origin” are shown, respectively. FIG. 4B shows positions assigned to display Japanese obtained by translating the words of the program.

As is clear from these figures, if the word position in the case of Japaneseization is divided into ~, the Japanese position of the translated Japanese is displayed for each ~ position. , Japanese and numeric values for position, Japanese and numeric values for position, Japanese and numeric values for position, numeric values for position By assigning and displaying the Japanese and the numerical values of the Japanese and the numerical values, the Japanese language of the position, and the Japanese of the numerical values for the position, respectively, Japanese language display can be achieved as follows.

<Embodiment 4> FIG. 6 is a flowchart showing another embodiment of the natural language display method according to the present invention. The difference from the embodiment of FIG. The Japanese language associated with the searched NC language is read from the table (4 '), and in step Japanese language display format data associated with the NC language is read from the table (4'). The only difference is that a processing step of applying the Japanese read from (4 ′) to the relevant portion of the Japanese display format and displaying the Japanese is adopted.

Therefore, also in the case of this embodiment, the Japanese language corresponding to the predetermined portion is displayed, so that a remarkably easy-to-read Japanese language display can be achieved.

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

As shown in FIG. 3A, a word is extracted in a step, the extracted word is translated into Japanese in a step, one word of Japanese is displayed in a step, and a next word is displayed in a step. The contents of the buffer are taken out in order to perform the processing of, and it is determined whether or not it is EOF in the step, and if it is not EOF, the processing of the step is performed again.
The series of processing ends as it is.

FIG. 4B is a flowchart for explaining the processing of the steps in detail.
Characters are read out, stored in a buffer in a step, and it is determined whether each is EOF or a line feed code in the step. If it is determined that neither is the case, the program is read out by one character in the step, and Whether each is EOF,
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 a step, and the processing of the step is performed again. vice versa,
If it is determined in the step that the character is any one of EOF, a line feed code, and an English character, in the step, the most recently read one character is returned to the program memory, and a series of processes is ended. Also, in the case where it is determined in the step that it is the EOF or the line feed code, the series of processing ends as it is.

FIG. 11C is a flowchart for explaining the processing of the step in detail. In the step, the contents of the buffer are taken out, and in the step, it is determined whether it is EOF or a line feed code. In this case, the contents retrieved from the buffer in the step are compared with the contents of the table (4). If the contents match, the contents of the buffer are replaced with the corresponding Japanese characters in the table in the step, and a series of processing is completed as it is. I do. Also, if it is determined in step that the code is EOF or a line feed code, or if they do not match in step, the series of processing ends.

FIG. 11D is a flowchart for explaining the processing of the step in detail. In the step, the contents of the buffer are extracted, and in the step, it is determined whether the buffer is EOF or a line feed code. If it is determined that none of them is present, a display based on the contents of the buffer is performed in a step, and a series of processing ends. If it is determined that it is a line feed code, the display is shifted to the next line in a step, and a series of processing is ended. Further, when it is determined that the EOF has occurred, the series of processing ends.

Therefore, in the case of this embodiment, the program is taken out one word at a time on the basis of English characters, line feed codes or EOF, and is translated into Japanese one word at a time. By repeating only a series of processes, the program created in NC language can be displayed in Japanese.

The present invention is not limited to the above-described embodiment. For example, instead of displaying in Japanese, it is possible to display by translating into any natural language such as English, French, Spanish, etc. Natural language can be displayed in an arbitrary format different from that shown in FIG. 5, and various other design changes can be made without changing the gist of the present invention.

<Effects of the Invention> As described above, the first invention divides a program created in the NC language into one word at a time and translates each word into a natural language and displays it. Therefore, the NC language cannot be understood. Even an operator can understand the contents of the program accurately, and even if the NC language differs depending on the maker, machine, etc., it can be easily dealt with simply by changing the table or the contents of the table. A unique effect is achieved in that natural language display can be achieved which is remarkably easy to see as compared with the case of sequentially displaying in natural language.

In the second invention, a program created in the NC language is divided into words, and each word is translated into a natural language and displayed. Therefore, even if an operator cannot understand the NC language, the contents of the program can be read. Can understand correctly, and
Even if the NC language differs depending on the maker, machine, etc., it can be easily dealt with only by changing the table or the contents of the table, and the natural language which is remarkably easy to read compared to the case of displaying in the natural language in the order of program division This has a specific effect of achieving coded display.
