Abstract

PURPOSE:To attain the conversion of the numerical control NC data format of an ISO or EIA standard into the NC data undergone the standard formatting, by using a data code standardizing means and a delimiter deleting means, etc. CONSTITUTION:The standards including ISO, EIA, JIS-7, etc., are previously stored in the form of the NC data codes. Then the NC data 4, e.g., the NC data of the ISO standard of a specific NC device is sent to a data code standard izing process 5. Thus the data 4 is changed into the standardized data in the process 5 by a program which converts the ISO standard in the data 4 into the JIS standard by the ISO standard stored in the file 1. Then the standardized data 4 is converted into the JIS standard, e.g., the codes of JIS-7. These codes are supplied to an NC data format standardizing process 7 via a delimiter deleting process 6 and standardized. Thus it is possible to convert an NC data format of the ISO standard, etc., into the NC data that have undergone the standard formatting.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for converting NC data format into standard formatted NC data.

[Technical Background of the Invention and Problems Therein] Known standards for NC data formats for sterilizing NC machines include ISO standards, HIA standards, and JI8 standards, which are considered standards, depending on the configuration method.

Since the NC machine is driven according to one of the above standards, there is a problem that if the data format is different, the NC@ cannot be driven.

[Purpose of the invention]

The present invention has been made in response to the above-mentioned problems, and provides a method for converting NC data formats configured according to ISU standards and EIA standards into standard formatted NC data.

[Summary of the invention]

That is, the present invention provides a means for converting a data code of a specific NC data format into JIS format, a means for deleting a delimiter code from the data converted to JIS format, and a means for deleting a delimiter code from data footnotes, numbers,
The present invention provides a method for converting an NC data format into standard formatted NC data, which is provided with means for obtaining data codes of the same length formatted in a standard format for operands such as characters.

[Embodiments of the invention]

Next, an embodiment of the method of the present invention will be described with reference to all the drawings. NC data that controls a specific NC machine, such as ISO standard data 7 formatted NC
An example of converting to a database will be explained.

First, the NCC data extrinsic database will be explained.

That is, as NC data codes, ISD, EIA, JI
Standards such as S-7 are stored in advance in the data code file (1).

In addition, delimiters between each step of the NC data are stored in the entire delimiter code file (2), and individual operand attributes in each step of the NC data are stored in advance in the operand attribute file (3).

The NC data (4) of the I80 standard stored on the NC tape is sent to the data code standardization step (5) as shown in FIG.

NC data (4J) is stored in each delimiter information storage section (4J) in each delimiter information storage section (4I).

That is, I stored in advance in the data code file (1)
ISσ standard in NC data (4) is JI based on SO standard.
In the data code standardization step (5), the data is converted into a JIS standard, such as JIS-7 code, which is considered as standardized data.

Delimiter deletion process (6) for the converted JIS-7 code
By deleting the delimiter code from the JIS NC data using the delimiter information stored in the data code file (2), the length is divided into multiple steps at the part with each delimiter code. NC data 6υ of the configuration shown in FIG. 1 (q) with different values are obtained.

In this way, the NC data 6υ from which the data code has been deleted is supplied to the weighting process (power).

In other words, the NC standardizes each step of the NC data.
Data format standardization process συ, operand standardization process in NC data based on operand information from the operand consistency file (3) ts+, command standardization to standardize commands that are the constituent elements of t helland, multi-color characters, etc. (9), Number standardization Ell), Character standardization circle is performed.

The NC data standardized in this way is shown in Figure 1 ((,
) from the data structure of each block as shown in Figure 1 ◎
The NC data σ2 of the data fort is obtained at the output.

The NC tape No. 111 (H) has an already known storage structure, and each delimiter (43 stores the contents of which process is to be executed in the next process), and the NC data of each delimiter q force is stored in each delimiter (43). is configured to store data such as the above-mentioned command numbers and characters.

The standard formatted NCC data pace is also NC data that can be replaced as a data format that is easy to handle in CAi)/CAM.

The means for standardizing the data code (5) from the NC data (4) stores in advance a correspondence table as shown in FIG.

That is, extract the JIS pointer for the I80 code in FIG.
JIS code in figure (8)? Standardization is performed by outputting. A specific example of standardization of the NC data format will be explained with reference to Figures 3 to 9.The NC data that drives the NC machine is as shown in Figure 3 (S,
S8. ...Consists of steps Sn, each step (S
), each operand (OP) is configured to have a different size. An example of such a data format is ISO
These include SO2FIA@ and Raku.

As shown in Figure 4, the NC data of such a formano) is converted into an NC data format with the same size for each operand (UP) and each step (S).
It is a means of obtaining data. An example of a data format in which OP and S have the same size is the JIS standard. .

First, one action unit of NC data is broken down into three components of commands, numbers, and characters, each consisting of multiple steps with different lengths, and each of the above components stored in advance in the NC data attribute file is analyzed. Using attributes, a component part is created for each step in which the command number, character code, and length are coded to a predetermined constant length, and this is combined to create NC data coded to a constant length for each step. You can repeat the operation to obtain it.

Next, it will be explained more specifically. That is, N shown in FIG.
Assuming that the components of each step and each operand for C data are composed of commands, numbers, and characters, the contents of each operand are $11r& by which of the 15 patterns shown in the fifth factor. There will be. A method for converting NC data having such a configuration into the same length for each operand and each step is shown in the flowchart of FIG. That is, for the NC data shown in FIG.
(101) LA then counts from operand 1 (
102) Execute division into three components sequentially from operand 1 of LA step 1. That is, the attributes for the three elements of numbers, commands, and characters are stored in an NC data attribute file, and the attributes from this attribute file are compared with the input NC data to identify "numbers" and "commands" for the NC data.
Divide into three important parts of ``characters'' (l O3). Standardization steps (104), (105), and (106) are performed for each divided "number,""command," and "character." In other words, the constituent elements "numbers" divided from the NC data are compared with the attribute codes of numbers, commands, and characters that have been stored in the attribute file in advance for the standardized data that has been completed in the number standardization step (107). , command, character,
The presence or absence of numbers is determined (10B), and if there are commands or characters, the respective standardization steps (109) (110
). Furthermore, when there are only numbers, the standardization step (104) is ended as "none". In addition, in the respective standardization steps (109) and (110), after similarly performing the standardization process, the respective processed foods are stored in the above attribute file.

Compare with the attribute code (111) (112) and check the presence or absence of each character and command. If yes, repeat the process of standardizing characters and commands (113) and (114) and end. do. Command standardization and character standardization are also performed in the same way. The state in which these processes have been executed is counted by a counter (115), and this count is combined with the pre-stored number of operands (UP) constituting one step.
m) and -step's last operand (OP
Repeat until m), repeat the above process, TJPm
When completed (116), it is output as -step completed, and the number of steps completed for that operation is output (117)
do. Compare this count number with the pre-stored number of steps that make up the NC data, and check whether the operation can be repeated until the last step (S-n) is completed (118)
When L and S-n are completed, the process ends 119.

The standardization process for each command, number, and character described above is as shown in the flowcharts of FIGS. 7 to 9.

Each command standardization process is as shown in the flowchart shown in FIG. The code and number of digits of the command stored in advance as a standard to be converted are obtained from the Uchi, N, and C data attribute files (121).

This read content is compared with the input NC data (122), and it is determined whether the command code and the number of digits are equal (123). If they are not equal, the code is output as is with a predetermined length. On the other hand, if they are equal, the number of digits of the command code of the input NC data is stored in the command set area (124), and the process ends (125). In this way, commands are standardized.

Further, each number standardization process is as shown in the flowchart shown in the eighth leg.

That is, Gυ reads the number of digits of a number made to a certain length from the attribute file. Place a flag (f) on the number “0” (
132). Next, count the number of steps (133),
The input NC data (134) is sequentially determined from operand 1 in step l to determine whether it is a number (135), and if it is a number, it is determined whether there is a "0" in the number (136), and " If there is a number "0", it is determined whether the number "0" is equal to the "0" that set the flag (f) above (137), and if it is "0", the number "0" is But if they are not equal, count (1
38) Set the number other than the flag rOJ to the number set area) (139).

Step number run for these processes) (140)
The process (1) is repeated until the number of digits stored in advance is reached.
41), set the numeric part in the numeric set area for output, and obtain a fixed length numeric code output with "0" stuffed into the remaining digit parts. That is, a code is obtained in which the numerical part is shifted to the right, and the process ends (142).

In this way, numbers are standardized.

Next, the standardization process for each character is shown in a flowchart in FIG. That is, the number of digits of a character is read from the NC data rigidity file (151). Next, count the number of steps Q
s2) Regarding L, input NC data (153), from step l to determine whether there is a me1 table of contents character (154)
)I do. If there are characters, compare and determine whether there is a pre-stored space (@) in the data (15
Do 5).

When there is no space, delete a character in the character set area for step 1 of the manual NC data (156).

That is, the characters are set to left justified. (157) L, repeat the process until the number of digits stored in advance is reached (158) and end (159)
do.

In this way, characters are standardized.

〔Effect of the invention〕

As explained above, according to the method of the present invention, it is possible to obtain a method for converting NC data of ISO standards and EIA standards into JIS standards, which are standard standards.
If it is 0%, it has the effect of converting and using NC tapes of other standards.

Furthermore, there are effects such as the ability to obtain a replacement signal for the CAD/CAMJIJNC data.
