FIG. 31 is a flowchart showing the processing contents of the NC data creation method for the metal plate sequential forming apparatus according to one embodiment of the present invention, and FIG. 32 is for the metal plate sequential forming apparatus according to one embodiment of the present invention. It is explanatory drawing of the graphic data produced by the NC data production method.
[0060]
When creating NC data for drilling, a solid line is basically used in the plan view of the bent part, so NC data for drilling is created for bending, overhanging, and burring forming lines. The outlines are drawn using the alternate long and short dash lines, dotted lines, and alternate long and two short dashes lines.
[0061]
In FIG. 31, the processing content of steps s100 to s150 is processed by the punching data creation device 100, and the processing content of steps s200 to s270 is processed by the sequential molding data creation device 200.
[0062]
In step s100 of FIG. 31, the calculation means CPU1 of the drilling data creation device 100 creates a developed view composed of outlines in FIG. 32 using the drilling NC data creation software and displays it on the display means DIS1. At this time, in the developed view, a hole HO1 for drilling is also created and displayed with a solid line.
[0063]
In step s110, using the input means I / O1 of the drilling data creation apparatus 100, bend lines DL1, DL2,..., DL6 indicating the bends are additionally created with a one-dot chain line in the developed view displayed on the display means DIS1. And display.
In step s120, using the input means I / O1 of the punching data creating apparatus 100, the overhang forming lines PL1 and PL2 indicating the overhang portions are shown as broken lines in the development view displayed on the display means DIS1. Create additional and display.
In step s130, using the input means I / O1 of the punching data creation device 100, the developed hole displayed on the display means DIS1 is processed by punching for preparing a burring hole for burring. The pilot hole shape line HO2 is additionally created with a solid line, and the molded line BL1 is additionally created with a two-dot chain line in a reference form and displayed.
[0064]
In step s140, the calculation means CPU1 of the drilling data creating apparatus 100, as shown in FIG. 32, shows the bending lines DL1, DL2,. The graphic data of the developed view to which the line HO2 and the formed line BL1 are added is stored as graphic data Dp.
[0065]
In step s150, the calculation means CPU1 of the drilling data creation device 100 creates NC data for drilling processing based on the drilling hole shapes such as the drilling hole HO1 and the pilot hole shape line HO2 drawn in the developed view. And output as perforated NC data D1.
[0066]
On the other hand, in step s200, the calculation means CPU2 of the sequential molding data creation device 200 reads the graphic data Dp created by the drilling data creation device 100 using the NC data creation software for sequential molding and displays it on the display means DIS2. .
Next, in step s210, the material and plate thickness, which are material data, are respectively input using the input means I / O2 of the sequential forming data creation apparatus 200.
[0067]
Next, in step s220, the calculation means CPU2 of the sequential forming data creation device 200 can automatically identify the one-dot chain line as a bend line from the read graphic data Dp by the line type. Automatically extracts by distance from the end face.
Next, in step s230, when the input means I / O2 of the sequential forming data creation apparatus 200 is used to select one element of the inner shape and the outer shape of the overhang forming line, the arithmetic means CPU2 configures the continuous straight line and the R configuration. To automatically extract the overhang. For example, the overhang forming line PL1 is selected by clicking with an input means such as a mouse, and designated as an outline using the input means. Further, the overhang forming line PL2 is selected by clicking with an input means such as a mouse and designated as an inner shape line with the input means. By selecting the inner shape line and the outer shape line, the calculation means CPU2 automatically extracts the overhanging portion by the configuration of the continuous straight line and R.
Next, in step s240, the overhang height is input using the input means I / O2 of the sequential forming data creation apparatus 200.
[0068]
Next, in step s250, when one element of the pilot hole of the burring forming line is selected using the input means I / O2 of the sequential forming data creation apparatus 200, the calculation means CPU2 performs burring by the continuous straight line and R configuration. Automatically extract the molding part. For example, the pilot hole HO2 is selected by clicking with an input means such as a mouse and designated as a pilot hole for burring using the input means. When a pilot hole for burring molding is selected, the calculation means CPU2 automatically extracts a burring molding section by a continuous straight line and R configuration.
Next, in step s260, the burring height is input using the input means I / O2 of the sequential molding data creation apparatus 200.
[0069]
In step s270, the calculation means CPU2 of the sequential molding data creation device 200 automatically creates sequential molding NC data using a previously registered molding procedure and manufacturing condition database, and outputs it as sequential molding NC data D2. To do.
[0070]
As described above, in this embodiment, the NC data creation graphic data of the turret punch press for punching and the sequential forming apparatus can be shared, and the NC data for sequential forming can be created in a short time.
Further, by sharing the same graphic data, it is possible to prevent manufacturing defects.
