2. Description of the Related Art When designing a plurality of mechanical parts required for manufacturing a predetermined product, each designer creates a study drawing for each individual part, and each designer overlays the created study drawings. At the same time, the shape of the parts will be examined and the examination diagram will be modified to create the final examination diagram. And
A parts drawing is created based on this study drawing. Currently, it is the mainstream to create the above-mentioned study drawing and parts drawing using a CADAM system.
When designing a mechanical part using the AM system, two pieces of data, that is, a study drawing for studying the shape of the part and a part diagram for machining the prototype part, were created in separate files.

In the preparation of the study drawing, first, after displaying a plurality of parts on the screen, the part to be designed is selected, and the mechanical part to be designed as shown in FIG. Front view (PV), top view (T
V), bottom view (BV), left side view (LV), right side view (RV), etc. are displayed together with the origin of the position coordinates, and the shape of the component from each direction is examined to make an examination as shown in FIG. 9. FIG. 1 is created on a CADAM system drawing. Then, the data file of the examination FIG. 1 as shown in FIG. 10A is created.

When the data file of the study figure 1 is created, as shown in FIG. 10B, a part diagram 2 is created on the CADAM system drawing based on the study figure 1 separately from the study figure 1. To do. FIG. 10B shows a part diagram 2 on the CADAM system drawing, and the drawing frame 3 is shown in the part diagram 2.
Then, the part number, the part name, etc. are entered, the dimensions are entered in the part shape, and a part drawing data file different from the data file of the study FIG. 1 is created.

As described above, if the data files of the study drawing 1 and the part drawing 2 are created as separate files, both the data files of the study drawing 1 and the part drawing 2 must be changed when changing the shape of the part. Therefore, the following problems have occurred. (1) Design workability is reduced. (2) When the data of the study drawing and the parts drawing are inconsistent, it is difficult to know which is the correct information. This may lead to processing errors. (3) Since the same shape data is duplicated, the data amount is doubled, and the data management on the host computer side becomes enormous.

[0006]

In view of the above problems, the present invention improves design workability, prevents data inconsistency, and facilitates management of study drawing and part drawing data.
It is a point to provide a system for recognizing position coordinates of study drawings and parts drawings using the DAM system.

In the study drawing created and read from the created file, the movement amount and the rotation angle for returning from the study drawing to the parts drawing,
In the parts drawing, the movement amount and the rotation angle for returning from the parts drawing to the study drawing, and the movement amount and the rotation angle of both of them are automatically calculated and displayed on the display screen of the drawing in the specific direction extracted from the parts drawing. Is characterized by.

[0008]

[Example] As described above, conventionally, the study drawing 1 and the part drawing 2 were created in different files. However, in order to prevent inconsistencies between the figure shape of the study drawing and the figure shape of the part drawing, the study drawing It is necessary to create a parts drawing in the same file and unify the data.

The technical idea of the study coordinate and the component diagram position coordinate recognition system using the CADAM system of the present invention is as follows.
When a study diagram and a part diagram on an ADAM drawing are created on the same screen, the rotation angle and the amount of movement for automatically returning from the study diagram to the part diagram and from the part diagram to the study drawing are automatically calculated and displayed. ,
The point is that the study drawing and the parts drawing can be created in the same file.

FIG. 8 is a block diagram showing an example of a study diagram and a part diagram position coordinate recognition system using CADAM according to the present invention. The host computer 4 of the system of the present invention includes a CPU 5, a main storage device 6, and a CADA.
M7, IUE (Interactive User E)
xit) 8, drawing movement execution module (program) 9 on CADAM, CADAM drawing data file 1
0, a CADAM terminal 11 including a drawing file disk is prepared. The IUE8 is a user program that is a CA.
It is an interface for accessing the database of the DAM drawing data file 10.

With such a system configuration, the host computer 4 is provided with an environment using CADAM7 and IUE8. Also, the study drawing and part drawing movement execution module 9 is created in the host computer, and the environment is set so as to be executed by the IUE function.

The steps for creating a study drawing and a parts drawing in the same file using the system having the configuration shown in FIG. 8 will be sequentially described below. <Step 1> As shown in FIG. 1, a study drawing 12 for arranging a part drawing of a new part is displayed on the screen by trigonometry to create a study drawing.

<Step 2> As shown in FIG. 2, the drawing frame 13 of the parts drawing is designated on the screen of the examination drawing 12 in the position state of step 1.

<Step 3> As shown in FIG. 3, the drawing frame 13 specified in step 2 is moved to
Move it to the left. Then, the (X value, Y value, rotation angle R) of the current position state of each of the examined drawings is given a file name and stored in the main storage device 6 of the CADAM system.
The storage of the position state may be performed in step 1.

<Step 4> As shown in FIG. 4, all the drawings such as TV, PV, etc. of the examination drawing 12 or necessary drawings are moved and placed in the designated drawing frame 13 for parts drawing.
Then, the position state (X value, Y
Value and rotation angle R) are given with the same file name as in the study diagram, and C
It is stored in the main storage device 6 of the ADAM system.

<Step 5> As shown in FIG. 5, in the drawing frame 13 for parts drawing, a drawing work is performed in which dimensions, part numbers, parts names, etc. are entered. The position state of the component executed in step 4 may be stored in this step.

<Step 6> The examination drawing 12 and its position state, and the part drawing 14 and its position state are created in the same file.

Examination by the above steps The position state of FIG.
The position state of each drawing of the parts drawing 14 is created in the same file. When the parts drawing 14 is instructed to the CADAM system shown in FIG. 8 from the file created in the same file as described above, as shown in FIG. The component drawing 14a is plotted and displayed on the screen. In the plotted component drawing 14a, the X-axis movement amount, the Y-axis movement amount, the rotation angle ( X2
Y2, R2) is displayed near the origin for each of TV, LV, PV, RV and BV. In many cases, the movement amount and the rotation angle in each drawing do not actually become the same amount, and X2, Y2,
R2 has different values.

When actually using the system of the present invention, in addition to displaying the movement amount and the rotation angle for returning from the part drawing to the study drawing, a diagram in a predetermined direction from the plotted part drawing screen, for example, When the front view is excerpted and displayed, the movement amount and rotation angle for returning from the parts drawing to the study drawing are near the origin of the screen on which the front view is displayed, and the study drawing returns to the parts drawing near the origin of the study drawing. It is also possible to display both the movement amount and the rotation angle.

Examining the parts shown in FIG.
When the instruction to return to 2 is given to the CADAM system, a return examination FIG. 15 is displayed on the screen as shown in FIG. 7, and the X-axis movement amount for moving from the examination FIG. The axial movement amount and the rotation angle R are calculated for each figure and displayed near the origin. In the case of FIG. 7, all the figures are (X
1, Y1, R1) are displayed together with the examination diagram, but actually the movement amount and the rotation angle have different values.

As described above, the feature of the present invention lies in the fact that the movement amount and the rotation angle of both are conventionally calculated and displayed so that the study drawing and the parts drawing which have been created separately can be created in one file. Since the movement amount of each is stored in one file, the study drawing is displayed on the screen to change the shape of the part, and each movement is based on the amount of movement from the study diagram displayed in the study drawing to the part drawing. It becomes easy to return the directional drawing from the study drawing to the position of the parts drawing and execute drawing work. If further investigation is required, it is possible to change the shape of a part from the part drawing to the consideration drawing based on the amount of movement from the part drawing displayed in the restored part drawing to the consideration drawing. .

[0022]

According to the present invention, the work of changing both the study drawing and the part drawing when changing the part shape is eliminated, and the design workability is improved. Moreover, since the data of the study drawing and the parts drawing are unified, data inconsistency can be prevented. Further, the study drawing and the parts drawing can be created in one file, which leads to saving of drawing data storage means such as a disk.
