FIG. 4 is an example of a completed diagram of the present invention displaying the same content as FIG. 1.

To explain the method for creating a parts diagram according to the drawing procedure, first, a diagram of the material developed at a predetermined scale is drawn on the graphic display shown in FIG.
Alternatively, if there is a drawing of a specific shape that has been automatically drawn by inputting the shape code and dimensions in advance, it is displayed.

Next, a machining origin symbol 201 is called from the parts drawing symbol library 102 shown in FIG. 2 and attached to the corresponding position at the lower left of the developed material diagram already displayed. Next, a machining point symbol 202 is attached to the point to be machined, and a predetermined machining content code (for example, C, R, *ABCDEFGH, etc.) is entered using the key, and the machining point symbol 202 is attached to the same point as the machining point symbol. Furthermore, when "R" to "Z" are displayed as processing content codes, a table symbol 207 is arranged to display the details of the processing content, and the table symbol 207 is placed at a certain point (for example, points N1 to N3) in the table symbol. The details of the processing contents (for example, W, 20, 10, and F) are entered using the keys.

Next, if you need a rectangular corner notch,
Corner cutout symbols 203 are attached to the lower left and upper right points of the rectangle to be cut out. (In this example, the lower left point matches the attachment point of the machining origin symbol).

Next, bending symbols 208 and 209 are placed on the X-axis and Y-axis, respectively, on the central axis that requires bending (in this example, it is shown as a broken line for ease of understanding).

Next, the marking position symbol 204 is attached at a point that does not interfere with other processing.

Furthermore, attach the corresponding bending radius symbol 205 and surface treatment specification symbol 206 to any point,
Finally, enter the material, plate thickness (SPHC, 2 and 3 in this example) and material cutting dimensions (100 x 150 in this example) in the predefined positions, and finally display Figure 4 on the graphic display. It is completed on the device 102 and stored in a parts diagram drawing file.

(Description of Graphic Information Extraction) The input interface section 104 in FIG. 2 decodes the data in the parts diagram drawing file and stores it in the parts diagram graphics data file 105.

201 to 209 are symbol figures 201 in Figure 4, respectively.
This is the number that was pre-assigned to 209.

(Description of Graphic Data Analysis Processing Unit) Among the data recognized above, the symbol type code and data details are found for the symbol by referring to the data in the symbol master file 104 in FIG. 2 using the symbol number as a key item. First, for symbols whose type codes indicate a bending radius symbol and a surface treatment specification symbol, the corresponding data in the data breakdown column is recognized as bending radius and surface treatment specification data, respectively.

Next, for those whose symbol type code indicates the machining point symbol, its attachment point coordinates (X _KN , Y _KN )
It finds the NOTE located on the same coordinates as the machining point, recognizes it as the machining content code corresponding to the machining point, and then calculates the machining position coordinates (X _OKN ,
Y _OKN ) and stored as a set of data with the processing content code.

X _OKN = X _KN −X _O , Y _OKN = Y _KN − Y _O …(1) Now (X _O , Y _O ) is the mounting point of the machining origin symbol.

The details of the processing content corresponding to the processing content code are defined in advance, but in the case of undefined processing content,
Display using machining details codes “R” to “Z”,
Since the details are written in a predetermined position in the table symbol 207, the data is extracted and recognized as detailed data of the processing content. For example, in this example, for a symbol whose symbol type code indicates a table symbol, for its coordinates (X _T , Y _T ), [(X _T +
α ₁ ), (Y _T −β ₁ )] is found and recognized as the machining type and shape corresponding to the machining content code “R”.

Similarly, [(X _T + α ₂ ), (Y _T − β ₁ )], [(X _T + α ₃
),
(Y _T −β ₁ )] are recognized as the machining size and machining direction corresponding to the machining content code “R”, respectively. In this example, processing type, shape: W,
Recognized as 20, processing size: 10, processing direction: F.

Next, for symbols whose type code indicates the marking position symbol, based on the relationship between the values of the symbol's attachment point coordinates (X _I , Y _I ) and the attachment point coordinates (X _O , Y _O ) of the machining origin symbol, Marking position (X _OI ,
Find Y _OI ).

_{X OI = _ _ _ _ _} ), recognize that the first character of the data in the data breakdown of the symbol master is the bending axis direction, and the second character is the data indicating the front and back direction of bending, collect the corresponding bending symbols,
The bending positions are arranged in ascending order for each bending axis direction, and the combination of data arrangement in the front and back directions of bending is recognized, and a predefined bending pattern code corresponding to the arrangement combination is determined for each bending axis direction.

In this example, the bending in the X-axis direction is 1 in the front direction.
For each bending in the Y-axis direction, a bending pattern code indicating one bending in the back direction is recognized.

Next, from among the data in the part diagram figure data file, a NOTE with data of a specific coordinate point defined in advance is found, and the material, plate thickness, and material cutting dimensions are recognized respectively, and the following part diagram information is obtained. is created and filed in the parts drawing information file 108.

(a) Part drawing number (identification number) (b) Material material, plate thickness, and material cutting dimensions (c) Surface treatment specification data (d) Engraving position of part identification code (e) For each bending axis of bending process Bending pattern code and bending position, bending front and back directions, and bending radius (f) Machining content code and machining position coordinates for each machining point, and detailed machining content data such as machining type, shape, machining size, and machining direction (machining information synthesis processing (Explanation of part) Recognizes the part recognition code and part drawing number based on the manufacturing command information from the manufacturing command file 109, finds the relevant data in the parts diagram information file 108, and basically calculates the details of the machining content using the machining content code as a key item. The data is found in the machining information file 110 and recognized as data on machining type, shape, and machining direction.

In addition, the first character code of the processing content code is “*”
The ones that have a drawing number for drilling holes for attaching equipment, etc.
Since it is entered as a NOTE, the corresponding data in the basic machining information file 110 is extracted for the number of holes using the machining content code, that is, the drilling machining drawing number as a key item, and the machining type, shape, machining size, machining direction, and Recognize the processing point coordinate increment value (△X, △Y)).

Next, the position from the machining origin to each machining point is converted to obtain the machining point position (X, Y).

X=X _OKN +△X, Y=Y _OKN +△Y...(3) Now (X _OKN , Y _OKN ) are the machining position coordinates determined by equation (1).

Next, in order to stamp the post-work instruction contents above or below the processing point position, the marking information is edited as follows.

For a machining point with predetermined machining shape data (20 in this example), data on the engraving content and engraving position coordinate increment value are found from the engraving information file 111 in accordance with the machining type and machining size, and the machining point position ( The marking position (X, Y K ) is determined by adding the marking position coordinate increment value (△Y _K ) to the marking position (X, Y ₎ . However, (Y
If the value of +△Y _K ) is larger than the already recognized value (material cutting dimension Y _S - α ₀ ), it is not possible to engrave at that point, so the value of (X, Y - △Y _K ) is used as the engraving position. It is recognized and recognized as a set of data with the data of the engraving content.

Finally, for each machining point determined above, the machining shop group and standard machining time are determined from the standard machining time information file 112 using the machining type, shape, and machining size as key items, and the machining shop group is determined from the relationship with the number of pieces to be machined. The standard machining time for each is determined and used as instruction data for the worker as a target man-hour.

We create NC-processed tape using technology, perform hole punching with a press machine, tap the punched holes in the punched plate material, and use a marking device to mark post-work instructions such as welding. and parts recognition code are engraved on it.
The plate-like material processed by the shear is divided into sizes specified as material cutting dimensions, and parts can be manufactured automatically up to the point of cutting.
After that, (2) is entered in the work instruction slip (a) ~
Bending and other post-work can be performed using the information in (f) and the marks engraved on the parts.

For example, an explanatory drawing of the finished shape after bending corresponding to the bending pattern code may be prepared in advance, and the bending dimensions, direction, bending radius, etc. can be read from the post-work instruction slip. Also, during surface treatment, parts and slips are separated and painted, and the part recognition code engraved on the parts is compared with the part recognition code written on the post-work instruction slip. It is possible to attach a slip to the parts and transfer them to the assembly department. Even if a part were to come loose, the serial number and drawing number of the part can be determined based on the part recognition code engraved on it.
