The present invention relates to a control table creation device for a measuring machine for creating a control table that becomes the basis for the measurement.

[Conventional technology] In recent years, measurement data networks have been developed that centrally manage measurement data measured by various measuring instruments and share and effectively utilize this data among various departments such as the design department, manufacturing department, and quality control department. A system is being developed. In this type of system, CN C (Com
A variety of measuring devices are used as terminal measuring devices, from advanced measuring devices such as three-dimensional measuring machines to small measuring devices such as digital calipers and digital micrometers that have a function of outputting digital data.

There are problems in that it is not efficient and measurement errors are likely to occur. In particular, when selecting a CNC coordinate measuring machine as the measuring machine, the measurement operator has to create a command to give the measurement procedure based on the measurement instructions and input it into the coordinate measuring machine, which is a complicated task. However, there is a problem in that the burden on the measuring worker becomes even heavier.

Also, taking automatic measurement using a coordinate measuring machine as an example, even if the measurement instructions are the same, if the coordinate measuring machine used is different, the commands for automatic measurement will be different. Every time you change it, you have to create a new command and re-enter it. Therefore, there is also the problem that a lot of time is wasted on command input work.

The present invention has been made in view of such problems, and includes:
It is an object of the present invention to provide a control table creation device for a measuring machine that can significantly reduce the burden on a measurement requester and a measurement worker and create a control table that instructs efficient measurement work.

At the same time, the drawing information associated with the data table, a message necessary for the measurement work, and the storage location of the measurement data are added to the command to control the measuring machine, display the message, and transfer the measurement data. The present invention is characterized by comprising a control table creation means for creating a control table for performing control.

[Operations] According to the present invention, when the measurement requester inputs the measurement description,
The measurement description table creation means creates a measurement description table by appropriately integrating and sorting the data in an order that improves measurement work efficiency.

Further, when drawing information specifying a measurement location is generated by the drawing information creation means based on the operation of the measurement requester, this drawing information is associated with the measurement description using the data table.

Further, the control table creation means expands a command based on the created measurement description table, adds the drawing information to this command through the data table, and adds necessary information such as a guide message. Create a control table.

Therefore, according to the present invention, when the generated control table is used on the measurement terminal side, even if the measurement requester freely inputs the measurement description without considering the work efficiency during measurement, the work efficiency can be improved. In addition to giving measurement instructions with a high level of accuracy, it is possible to give extremely easy-to-understand measurement instructions to the measurement worker by utilizing the added drawing information, messages, etc.

Moreover, according to this invention, the measurement requester gives work instructions in the form of a measurement description, so there is no need to be aware of different commands for each measuring machine, and even if the measuring machine is changed, - Since the created measurement description table and data table can be utilized, no burden is placed on the measurement requester and the measurement operator.

In addition, by saving each table and drawing information separately, it is possible to make measurement technology an asset, and by using these for other measurements, it is possible to further improve the efficiency of measurement work. I can do it.

Therefore, according to the present invention, it is possible to significantly reduce the burden on the measurement requester and the measurement worker, and to improve the measurement work efficiency.

Of the measurement description tables created by the measurement description table creation section 1, data regarding elements and data regarding correlations are input to an element data table generator 7 and a correlation data table generator 8, respectively. Also,
Drawing information created by the drawing information creation section 3 and statistics/calculation designation information inputted by the statistics/calculation designation information input section 5 are given to the element data table generator graph. The element data table generator 7 adds this information to the element data portion of the measurement description table to create an element data table. The created element data table is stored in the element data table storage section 9. Further, the correlation data table generator 8 creates a correlation data table based on the input correlation data of the measurement description table. The created correlation data table is stored in the correlation data table storage section 10.

These three created tables, namely the measurement description table, the element data table and the correlation data table, are supplied to the control table generator 11. The control table generator 11 is configured as shown in FIG. 5, for example. That is, each measurement description constituting the measurement description table is supplied to the command expansion section 51 and the guide message selection section 52 in numerical order. When the measuring machine specified in the measurement description is a three-dimensional measuring machine, the command expansion unit 51 converts command expansion tables 12a and 12b+1 stored in the measuring machine side command expansion table storage unit 12.

Each terminal device 22. ~22□.

Next, the operation of the control table creation device according to this embodiment configured as described above will be explained.

In this measurement data network system, a measurement requester issues a measurement instruction using a measurement description table. The measurement description table is, for example, a table as shown in FIG. 6, and is divided into a header section 61 and a main table 62.

The header section 61 describes the product name, product number, general tolerance, measuring device used, parameters related to the measuring device, etc. of the object to be measured. In addition, this table 62 describes definition elements directly necessary for measurement work, projection plane, display surface, first element name, output designation, special designation, comment, second element name, correlation output designation, etc. be done.

In this table 62, the definition element column contains information for defining elements that are not measurement elements but are necessary for measurement reasons, such as information on the reference plane and origin when measuring with a coordinate measuring machine. is described. Here, XY, Y, and ORG indicate the XY plane, Y axis, and origin, respectively.

In the column of projection plane, information indicating the projection plane when measuring with a three-dimensional measuring machine is described. Here, xy, yz
, zx, etc. indicate that the XY plane, the 72nd plane, and the ZX plane are projection planes, respectively.

In the display screen column, a drawing of the object to be measured viewed from the terminal device 22. ~22. ．． Information indicating whether to display is described. This information can be omitted if it is the same as the projection plane.

In the name column of the first element, the element to be measured, for example Nα1
Elements such as a circle of 1 and a line of Nα13 are described with symbols.

Here, PLi+ CI i+ spi, p'ri
.

LIi+CYi, etc. indicate the line, circle, sphere, point, projection line, and cylinder of Nαi, respectively.

The willow of the output specification of the first element includes the items to be measured in the element specified in the name field of the first element, such as diameter, X coordinate, Y coordinate, X coordinate, etc. symbols, and the design value, An upper tolerance tolerance value and a lower tolerance tolerance value are described.

In the special specification column, information on the measuring device, probe, etc. to be used is described.

In the comment column, notes etc. that should be conveyed to the measurement operator are described.

In the name column of the second element, a symbol that defines the second element to be measured is written when two elements need to be specified, such as the distance between the centers of circles.

In the correlation output specification field, items to be measured in the relationship determined by the first and second elements, such as symbols such as distance and angle, design values, upper error limit tolerances, and lower error limit tolerance values are displayed. Described.

Next, a method for creating this measurement description table will be explained.

First, the measurement description editor 33 of the measurement description table creation section 1 shown in FIG. 3 is activated. In the measurement description editor 33, the measurement description input editing section 34 is activated, and thereby only the table frame of the measurement description table is displayed on the display section 32. The measurement requester operates the input unit 31 and inputs the measurement description necessary for giving the measurement instruction into the necessary locations within the table frame. Note that at this time, inputting the measurement description can be performed freely regardless of the measurement order, measuring device, etc.

In addition, when creating a table using a measurement description table created in the past, the measurement requester needs to use the input section 31
The built-in editing section 36 is activated by , and the table to be used is specified from among the measurement description tables stored in the measurement description table storage section 2 . At this time, for example, the display section 3
A multi-window is formed in 2, and the table currently being edited is displayed in one window, and the table specified above is displayed in the other window, making it easy to move data between both windows. This allows you to create tables efficiently.

This allows past data to be used effectively.

When all the items are written in the measurement description table, the measurement description editor 33 activates the input information check section 35. This checks whether there are any input errors or contradictions in element names, angle symbols, and parameters.

At this stage, each measurement description is arranged in a disjointed manner regardless of the order of measurement, measuring device, etc., so next an editing operation is performed to rearrange the descriptions into an order that takes into account measurement efficiency.

First, if there is an instruction to use a specific part of a measurement description table created in the past in the measurement description table, the built-in editing section 26 is activated and the measurement description table storage section 2 is accessed. Incorporate the necessary data into that part.

Subsequently, the measurement description integration unit 27 is activated, and as shown in FIG. 7, when different output symbols for the same measurement element are input separately, the output symbols are combined into one description. In the illustrated example, N[1
11 to find the x, y, z coordinates of the circle, and N(
The description of finding the diameter of the circle Ill is shown in the same figure (b
) is integrated into the description of finding the x, y, z coordinates and diameter of a circle of Nα11.

Finally, the measurement description sorting unit 28 is activated, and the measurement descriptions are rearranged in an order that takes measurement efficiency into consideration. Sorting is performed, for example, based on the following criteria.

■Compile measurement descriptions for each measuring device used.

■For coordinate measuring machines, compile measurement descriptions for each probe used.

■In the case of a coordinate measuring machine, compile measurement descriptions for each projection surface.

■Combine measurement descriptions into elements to be actually measured and elements determined by calculation.

■Compile measurement descriptions so that the detection parts such as the probe in the coordinate measuring machine and the lens in the projector can perform measurements with the shortest moving distance.

■As specified by the user, compile measurement descriptions so that only specific elements are measured preferentially.

By sorting the measurement descriptions based on such criteria, a measurement description table 82 that takes measurement efficiency into account is generated from a measurement description table 81 that does not take measurement efficiency into consideration, as shown in FIG. 8, for example.

The measurement description table generated by the above method is stored in the measurement description table storage section 2, and is also supplied to the element data table generator 7, the correlation data table generator 8, and the control table generator 11.

The element data table generator 7 and the correlation data table generator 8 generate a data area, which is a physical area on the storage device, for storing measurement data on the host computer 20 from the created measurement description table. The measurement data consists of element data determined by one element, such as the coordinates of a point and the diameter of a circle, and element data determined by two elements, such as the distance between two points and the distance between the centers of two circles. It is broadly divided into correlation data. Therefore, the element data table generator 7 creates an element data table that is a data area for element data, and the correlation data table generator 8 creates a correlation data table that is a data area for correlation data. The element data table created by the element data table generator 7 also includes a measurement description table, drawing information, and statistics Φ
It is also a table that associates calculation specification information with this information and assembles this information when creating a control table.

FIG. 9 is a schematic diagram showing an example of an element data table. That is, the element data table includes the index section 91 and the tree table 9.
2. The index section 91 contains pointers (memory N
(1) is stored. In addition, the tree table 92 has a memory Nα(
= data area 93 in which measurement data is stored in association with each element), and display data indicating which drawing to display in response to measurement instructions for the corresponding element and the position and form of the arrow. 94 and data 95 for specifying statistics and calculations, and the data 94.95 corresponds to a portion associated with the measurement description. Note that the display data 94 is created by the drawing information creation section 3, and the statistics/calculation designation data is input from the statistics/calculation designation information input section 5.

In addition, the correlation data table is also as shown in Figure 10.
It is composed of an index section 101 and a tree table 102. The index unit 101 stores a pointer (memory N(1)) to the corresponding correlation data from the names of the first and second elements for the row in which the contents of the correlation building exist in the measurement description table. Table 102 shows memory Nα (=each element)
The measurement data is stored in correspondence with the .

On the other hand, the measurement requester can import drawing information of the measurement target from the drawing input device 24, such as an image scanner, in conjunction with the creation of the measurement description table. Drawing information is CA
In the case of D data, the data may be directly imported from a CAD system.

When the drawing information is read by the drawing input device 24,
This drawing information is stored as original drawing data in the original drawing data storage section 42 via the drawing information editor 41 shown in FIG. Once the original drawing data is stored, the drawing information editor 41 displays the original drawing data as shown in FIG. 11(a) on the display section 46.

Next, the drawing information editor 41 displays the element names and drawing information sequentially sent from the element data table storage unit 9 on a specific part of the screen as shown in FIG. Prompt the measurement applicant to make corrections and specify the arrow symbol. In the example shown in FIG. 11(a), the measurement requester uses the drawing MS (
The original drawing data itself is registered as an overall drawing), and the position of the element name PLII is specified by selecting one of the four arrows by operating the mouse or the like on the input unit 45, for example.

For example, when 5PII is sent as the XY1 element name as a drawing, the measurement requester operates the mouse etc.
Cut out only the part of the projection of the XY plane from the original drawing data,
For example, as shown in FIG. 11(b), the drawing is enlarged appropriately and registered as the drawing name XY, and the arrow and its position are specified. Through similar operations, drawing information is registered for other drawings and other elements.

As a result, the drawing information editor 41 creates each plan data in which the drawing name 121 and the binary figure data 122 are paired, as shown in FIG. At the same time, as shown in FIG. 13, additional information indicating the element name, drawing, arrow type, X coordinate of the arrow on the screen, and the correspondence between do. The created drawing data and additional information are stored in the drawing information storage unit 4 as drawing information.
At the same time, it is transferred to the element data table generator 7, where it is incorporated into the element data table.

Further, the statistics/calculation designation information inputted from the statistics/calculation designation information input unit 5 is also stored in the statistics/calculation designation information storage unit 6 and transferred to the element data table generator graph, where it is shown in FIG. It is incorporated into the element data table as shown.

The element data table, correlation data table, and measurement description table created in this way are supplied to the control table generator 11, where they are used to create a control table.

FIG. 14 is a flowchart showing the control table creation procedure.

First, one line of measurement description is input from the measurement description table storage section 2 (Sl). If the measuring machine designation field in the measurement description is a three-dimensional measuring machine (S2), the command expansion unit 51 of the control data table generator 11 shown in FIG. 5 expands the mobile constant description into a CNC command. (S3).

At this time, since the commands differ depending on the model of the measuring device, the command expansion table 12 al corresponding to the model
l 2 b,! 2 Command expansion is performed with reference to c. This command expansion is executed, for example, in the order of command expansion for the reference plane designation operation, command expansion when the projection plane changes, command expansion for the first element, second element, and correlation output designation, and command expansion for the definition element. When the command expansion is completed, the guide message selection unit 52 searches the guide message dictionary 53 to check whether there is a guide message corresponding to the measurement description and the expanded command, and if there is a guide message, selects the guide message. Select (S4).

On the other hand, the control table generator 11 is supplied with element data memory Nα, drawing information, and statistics/calculation designation information using the element name of the measurement description as a key from the index section of the element data table. Further, the control table generator 11 is supplied with a memory Nα of element data using the element name of the measurement description as a key from the index section of the correlation data table.

Then, these pieces of information, the command developed by the command development section 51, and the guide message selected by the guide message selection section 52 are assembled by the information integration processing section 54 (S15), and one row of the measurement description table is assembled. Control table data for minutes is created. If this is executed for all rows of the measurement description table, a control table as shown in FIG. 15 will be created.

This control table is transmitted to the terminal devices 22□ to 22. through the communication controller 21 in FIG. , to the corresponding terminal device 22k. The terminal device 22 sequentially executes the control table one step at a time to control the operation of the measuring machine 238, and displays necessary guide messages and drawing information, etc., as shown in FIG. give measurement instructions to the person. In addition, FIGS. 16(a) and (b)
are the step N( of the control table shown in FIG. 15), respectively.
It shows the display form on the measurement terminal 22 when IO/1G and O/14 are executed.

Therefore, the measuring worker only has to proceed with the measuring work while checking such guide messages, drawings, and arrows indicating the measurement points, so that the burden on the measuring worker is significantly reduced.

[Effects of the Invention] As described above, according to the present invention, a measurement requester can freely input measurement descriptions without considering work efficiency during measurement. In addition, since the measurement requester gives work instructions in the form of a measurement description, there is no need to be aware of different commands for each measuring machine, and even if the measuring machine changes.
- Measurement description tables and data tables that have been created can be reused. Therefore, the burden on the person requesting the measurement can be significantly reduced.

In addition, according to this device, drawing information is added through the data table to commands developed based on the measurement description table, as well as guide messages.Using this on the measurement terminal side improves work efficiency. By using the added drawing information, message information, etc., extremely easy-to-understand measurement instructions can be given to the measurement operator. Therefore, the burden on the measuring worker is reduced, and the measuring work can be carried out efficiently.
