SUMMARY OF THE INVENTION It is an object of the present invention to provide a cutting die making system and a recording medium for quickly and easily applying a line image having a stepped blade shape to a contour image for forming a cutting die. It is in.

[0005]

Means for Solving the Problems and Action / Effect In order to solve the above-mentioned problems, a punching die making system according to the present invention, as described in the claims, punches a sheet material into a predetermined shape. In a blanking die creation system for creating a mold, a contour line indicating a shape to be punched is displayed on a screen, and a desired position is designated with respect to the contour line image displayed on the screen, and the designated position is designated. A cutting portion that is formed outside the contour line and cuts the remaining portion of the sheet material to be punched into a plurality of sections within a predetermined area set in advance to include (contain) the sheet material inside. It is characterized by generating and displaying a line image of a line of sight (hereinafter also referred to as a stitch line).

In a similar system, a contour line indicating a shape to be stamped is displayed on a screen, and a cut line formed outside the contour line and dividing the remaining portion of the sheet material to be stamped into a plurality of sections. In addition to specifying the line image form, a desired position is specified for the outline image displayed on the screen, and a preset position corresponding to the sheet material is set based on the specified line image form and position. In a predetermined screen area, one end of the cut line image is connected to or close to one side of the contour line, and the other end is an outer edge of a predetermined area or a side opposite to the one side. The cut line image may be adjusted and displayed so as to be connected to or close to the cut line.

[0007] That is, by specifying the line image form that is the basis of the cut line image and the position where the cut line image is formed, the cut line image is formed based on the line image form, and the contour image and its contour are formed. It can be formed so as to straddle the outer edge of the region set based on the line, or to straddle between opposing sides of the contour image. With simple and few operations,
Since it is possible to form a score line (steering edge line) that divides the scrap of the sheet material into a plurality of pieces, it is possible to reduce the time required for forming the cutting die.

[0008] The line image form of the score line can be formed by a plurality of line segments connected via a bent portion, and the score line image adjusting means is provided with respect to a predetermined score line forming direction. With respect to the side of the contour line inclined at a predetermined angle range, the cut line image can be adjusted so that the line segment image of the cut line connected to or close to the side is perpendicular to the side.

Since the cut line image is formed by bending a part of the image so as to be perpendicular to a predetermined side portion, it is possible to prevent the formation of an acute angle portion that is difficult to separate from the product portion in the waste portion. Can be. It should be noted that, compared to a straight stay blade, a stay blade having a shape bent in the longitudinal direction also has advantages such as being less likely to come off from the template.

The display means can simultaneously display the outline image and a plurality of position candidate images which are candidates for the position designated by the position designation means. By simultaneously displaying the outline image and the position candidate image, it is easy to specify the position with respect to the outline. Further, by displaying such a position candidate image in association with a contour image, for example, on a rectangular frame, it becomes easier to visually recognize the position candidate image.

It is to be noted that a program for realizing the processing in the above-described die forming system can be recorded on a recording medium such as a floppy disk, a CD-ROM, a magneto-optical disk, and a ROM card. And
By installing the program recorded on the recording medium into a computer system and a computer system equipped with a display device such as a CRT or a liquid crystal display and an input unit such as a mouse and a keyboard connected to the computer system, Can be used as the above-described die forming system.

That is, the pointer P displayed on the screen is aligned with a desired icon using the mouse 18, and then a click button (not shown) provided on the mouse 18 is pressed a predetermined number of times, so that the function corresponding to the icon is selected. The operation is enabled (hereinafter, such an operation is referred to as “click” or “mouse click”).

Prior to the start of the blanking die forming process, a development image 26 (FIG. 4) is read from the contour image data storage unit 24a as a contour image and displayed on the drawing area 44 (S1 in FIG. 6). Thereafter, for example, when an icon for starting the drawing formed in the icon group 42 is clicked, a setting display as shown in FIG. 7, that is, a program for executing the cutting die creation process is started, and the drawing on the CAD screen 41 is started. A basic setting screen 50 for creating a die is superimposed on the area 44. The basic setting screen 50 is used for setting display colors on the screen such as the above-described various frame lines such as the product frame, the stay blade frame (or the sheet frame), and the form frame, and the outline image for the drawing area 44 of the CAD screen 41. A display position (hereinafter, also referred to as an outline reference position) of the (development view 26) is set, and each display section is formed for each setting item. As the contour reference position, various settings are stored in advance in addition to the setting for matching the center position of the contour image 26 with the center position of the drawing area 44. When the reference position change button 51 is clicked, the display section is displayed. At 52, selection candidates for various settings are displayed. By selecting a desired reference position from the selection candidates, the contour image 26 is moved and displayed so that the reference position set in the contour image 26 matches the center position of the drawing area 44.

After setting the display color and the center position (S2),
When the execution button on the screen is clicked, a frame size input screen 53 for setting various frame sizes for the outline image 26 is displayed as shown in FIG. The product frame 30 is
According to the maximum width position of the developed view in two directions perpendicular to each other, that is, the vertical direction and the horizontal direction, two parallel lines passing through both ends in the horizontal direction of the contour image 26 and upper and lower ends in the vertical direction are passed. It is set by a rectangular frame line formed by two parallel line segments (S3). The setting of the stab blade frame 34 that defines the outer edge position of the stake blade is performed by individually inputting the respective dimension values of the product frame 30 in the vertical and horizontal directions into a display window shown in the drawing. The length and width of the mold 36 indicating the outline of a plywood (hereinafter, also referred to as a mold) serving as a base of the punching die are set by inputting dimension values in each of the horizontal and vertical directions. A center line bisecting the direction (horizontal direction) passes through the center of the product frame 30 (S4). These product screen 30, setting blade frame 34 and formwork 36 for the setting screen are
It is stored in advance in the data storage unit together with the image data of the setting screen.

When the dimension value is set for each frame on the frame dimension input screen 53, a setting screen 58 (FIG. 9) for setting the arrangement position of the fixing screw insertion hole to the template is displayed. . In other words, a plurality of screw insertion holes (screw holes, etc.) through which screws for fixing the template to the punching device are formed are formed in the template such as a plywood plate. It is necessary to decide. The screw insertion hole 60 has a hole diameter, an arrangement interval, and the like specified by a screw hole formed on a mounting surface of a punching device on which a template is mounted. Setting screen 58
Is designed to input a vertical distance and a horizontal distance between adjacent screw insertion holes 60, and each screw insertion hole 60 is
It is set by inputting the hole diameter and spot facing diameter.

The size and arrangement interval of the screw insertion holes 60 formed in the template are obtained by converting a screw insertion hole pattern set so as to correspond to each of the manufacturer, model number, and other types of the punching device into data. You can also memorize it. On the setting screen, the model number and the like of the punching device may be displayed, and by selecting the displayed model number and the like, the screw insertion hole pattern stored in correspondence with the model number may be displayed as an image.

Following the setting of the screw insertion holes 60 and the positional relationship between them, the screw insertion holes 60 and the mold (veneer frame) are set.
36, and the arrangement position setting processing is performed (S5). The setting of the arrangement position of the screw insertion hole 60 is performed on the setting screen 62 as shown in FIG. 10, and for example, with respect to the arrangement direction center line 64 of the screw insertion hole row 63 arranged at the bottom on the screen. The distance 1 to the underline of the product frame 30 and the distance 2 to the underline of the veneer frame 36 are input. In the rotary cutter type punching machine, such a setting at the lowermost stage is a setting on the tip side in the rotation direction.

After inputting these values, the execution button is clicked to move to the next step. The setting screen 65 shown in FIG.
A candidate image is set on the product frame 30 as a guide for specifying the position when the cut line image is provided (S6). Setting screen 65
Displays two line segments that intersect each other at right angles at one corner of the product frame 30 and two mark images 66 each serving as a guide at the time of setting on each line segment.
Between the vertical distance and the horizontal distance. By inputting the vertical distance and the horizontal distance in advance in this way, as shown in FIG. 12A, the vertical and horizontal distances are displayed on the frame of the product frame 30 displayed on the drawing area 44 later. A mark image (hereinafter, referred to as a mark image) is provided at the coordinate positions calculated by the geometric operation module so as to be equally spaced in the direction.
67) will be displayed. Displaying the selection candidate points 67 makes it easy to specify the position where the stay blade is formed, as described later.

When the setting of the screw insertion hole 60 and the selection candidate point 67 is completed in each setting screen, as shown in FIG. 13, the drawing area 44 on the screen has the contour 26 and the product determined by the contour 26. Frame 30, its product frame 3
The stay blade frame 34 and the mold frame 36 that are larger than 0, the selection candidate points 67, and the screw insertion holes 60 are superimposed and displayed on the same screen (S7). The screw insertion holes 60 are displayed on the entire form 36 at intervals set on the setting screen 58 in FIG. 9.
For example, when the contour line (the position where the punching blade comes) and the fold line (the position where the grooving blade comes) pass through the spot facing circle, the circle image indicating the spot facing diameter and the circle image indicating the insertion hole are: The information is deleted from the screen (S8). This means that the formation of the contour line and the fold line has priority over the formation of the screw insertion hole. It should be noted that, when a cut line (steering edge line) described later is generated and displayed starting from the selection candidate point 67, the circle image of the screw insertion hole overlapping (interfering with) the cut line is automatically deleted from the screen. This will be described later.

After the above-described preparatory steps, a predetermined icon is clicked, and the cutting die making system 1 proceeds to the processing for generating and displaying the stitch line in S9. FIGS. 14 and 15 show the flow of the stitch edge line generation / display processing. In the step edge line generation / display processing, as shown in FIG. 16 at T1, a plurality of step edge line image form selection candidates are simultaneously displayed in the display area for each shape of the selection screen 70 by screen division. It has become. Note that the plurality of selection candidates for the stay blade shape may be sequentially displayed in the same display area by switching screens.

Here, the shape 0 is a shape in which a long line segment 71 and a short line segment 72 are connected in an obtuse bent form to form a stay blade line, and the line segment 72 extends along the horizontal direction. Shape 1 has a long line segment 71 extending along the vertical direction, and shapes 3 and 4 are symmetrical shapes of shapes 0 and 1 respectively. Shape 2 is a simple straight edge line consisting of one line segment, shape 6 is a horizontally long straight edge line bent at a right angle, shape 7 is a similar vertically long straight edge line, and shapes 9 and 10 are respectively Shape 6,
7 is a left-right symmetric type. In general, the shape 11 is a mode in which, when the connecting line does not form a right angle when the connecting line does not become a right angle when the connecting line is directly connected to the contour line, the cutting line is automatically generated in a polygonal line form so that the connecting line becomes a right angle. Note that the above shapes 0, 1, 3, and 4 are not automatically generated so that the connection portions are at right angles, while presuming that they are connected at right angles,
When it is desired to bend the extended portion for some reason, the angle is manually input to obtain a desired polygonal-shaped stitch blade line.

That is, as shown in FIG. 17B, in the shapes 0, 1, 3, and 4, the line segment 72 forming a part of the stay blade line is perpendicular to the side of the contour line. Then, a line segment (steering blade bent portion) 71 is formed at a predetermined angle (the angle is manually input). As shown in FIG. 17A, in the shapes 6, 7, 9, and 10, the formation direction of the line segment 73 of the cutting edge line is set in the screen in the vertical or horizontal direction, and the tip portion (on the cutting edge frame) (Coming) to line segment (stitch blade bent part) 7
Reference numeral 4 denotes a shape connected at right angles. This hook-shaped bent portion 74 helps to prevent the stay blade from coming off the template.

When a mouse is placed on the display portion of the target shape from the simultaneous selection of a plurality of stitch blade line shape selection candidates shown in FIG. 16 and clicked (T2), the display area is highlighted and executed in that state. Clicking the button confirms the selection. For example, by selecting the shape 9 in FIG. 16, a dimension determination screen 75 as shown in FIG. 17A is displayed. In the stay blade line shape shown in shape 9 (the same is true for shapes 6, 7, and 10), the line segment 74 is different from the line segment 73 of the stay blade line.
(The bend portion) is bent at a right angle, only the length dimension of the bend portion 74 is set, and the other line segment 73 is set.
Is automatically adjusted in length by the cut line image adjusting means. Also, for example, when the shape 3 in FIG. 16 is selected, FIG.
A dimension determination screen 76 shown in (b) is displayed. Shape 3
When the stitch blade line shape of (shapes 0, 1, and 4 is also selected) is selected, the length of the line segment 71 can be automatically adjusted, and the length of the line segment 72 is input. A bending angle with the line segment 71 is input.

After selecting the shape and determining the dimensions (T3),
Proceeding to T4, for example, as shown in FIG. 20, by selecting an arbitrary point from a plurality of selection candidate points 67 displayed on each of the vertical and horizontal frame lines of the product frame 30, the cut line image adjusting means As a result, the cutting edge lines based on the selected shape are sequentially formed.

When, for example, the shape 9 in FIG. 16 is selected as the step blade shape, the score line image adjusting means executes the following processing, for example. As shown in FIG. 20A, by specifying the selection candidate point 67 (on the product frame 30), the process proceeds to T5, and the stitch blade line is connected from the coordinates of the specified position and the forming direction of the stitch blade line. Is extracted. The point 67, which is the designated position, is designated in the area 33 on the screen surrounded by the side portion 26a of the contour image and the stab blade frame 34. Furthermore, from T6 to T7
After the intersection point between the side portion 26a and the cutting edge line and the intersection point between the cutting edge frame 34 and the cutting edge line are calculated by the geometric calculation module, as shown in FIG. The line segment 73 of the edge line connects the side portion 26a and the stay blade frame 34, in other words, the contour line (26a) and the stay blade frame 34
Is generated and displayed so as to cross the region 33 formed between the two (T8), and a bending portion 74 is generated and displayed on the bending edge frame 34 at the tip thereof (T8). T
9).

When the shape 2 in FIG. 16 is selected in advance, as shown in FIG. 18, for example, a selection candidate point 67 on the product frame 30 (in this case, the product frame 30 and the side 26a of the contour line) Are specified on the same straight line) (such as clicking with a mouse), a simple straight streak line 76 from the point 67 to the streak frame 34 is drawn to the side 26a.
Is automatically generated and displayed in a direction perpendicular to.

Further, when the shape 3 in FIG. 16 is selected in advance, for example, as shown in FIG. 19, by specifying and inputting a selection candidate point 67 (such as clicking with a mouse), the point 67 is set as a starting point. , A line segment 7 of length a
2 and a line segment 71 bent by the angle θ from this are displayed by automatic generation, and the tip of the line segment 71 extends to the stay blade frame 34. The length a and the angle θ are the fixed values input in FIG. 17B, and the bent cutting edge line instead of a straight line as shown in FIG.
It can be used for avoiding the interference between 1) and the stay blade line or for other appropriate circumstances.

When, for example, the shape 11 is selected on the selection screen 70 in FIG. 16, the processing flow is as shown in FIG. As shown in FIG. 21A, the shape 11 is such that the stay blade line 77 is designated by inputting only the length of a line segment 77b whose length is adjustable, and the length of the side portion 2
A line segment 77a whose direction is automatically adjusted so as to be connected or approached at a right angle to 6b is connected. In such an image shape of the step edge line 77, a position in an area where the side connected to the step edge line is inclined, such as an area sandwiched between adjacent flaps, is specified. As an example,
The flow when the selection candidate point 67a in FIG. 13 is designated will be conceptually described. As shown in FIG. 21B, a distance a from the side 26b (this distance a has been input in advance)
A straight line 26b 'parallel to the side portion 26b is virtually set (T12), the intersection of the virtual straight line 26b' and the line segment 77b is obtained, and the line segment 77b is adjusted so as to be connected to the straight line 26b '. (T13-15). Then T16
The line 77a 'is formed so as to be perpendicular to the side 26b from the end of the line 77b' whose length has been adjusted, as shown in FIG.

When the connection form does not become a right angle (outside the right angle) as it is with respect to the side as described above, an adjustment process of partially bending and connecting the side so as to become a right angle is performed.
Although it is possible to implement evenly even if the angle slightly deviates from the right angle, as shown in FIG. 22, a certain allowable range (for example, ± angle α) is set for the right angle, and in this allowable range, Even if it comes off, it is also possible to perform a process of connecting straight as it is without bending a part. If the side portion 26b is within the allowable range, the line segment 77b of the stay blade 77 is directly connected to the side portion 26b. In this case, the process proceeds from T11 to T17 in FIG.
In substantially the same manner as in the processing shown in FIG. 14, the length of the stay blade line is adjusted in the horizontal (or vertical) direction with respect to the screen,
Will be connected. If the value of the distance a shown in FIG. 21 is set to 0, it is possible to obtain a stitch blade line connected to the side while the stitch blade line extends in the horizontal direction by the same drawing method as in FIG. By utilizing this, substantially, FIG.
The same result as in the case of can be obtained.

As an extension of FIG. 21, it is also possible to automatically generate and display a stitch line 78 as shown in FIG. As a premise, in the embodiments described above, the selection candidate points are displayed uniformly at predetermined intervals on the product frame 30. In addition, or instead, the operator may select the selection candidate points. If a setting is input by clicking with a mouse or the like, an arbitrary portion on the screen can be selected as a reference point for forming the step blade. Here, as an example, the above-mentioned mode in which the reference point is displayed at a plurality of positions and the operator uses the appropriate number of the reference points to obtain the reference point of the stay blade, The mode switching operation can be selectively performed between a mode in which a reference point is obtained by a typical setting input (such as clicking) and a mode in which the above-mentioned uniform display is performed and an operator can freely input a setting. Now, assuming a mode in which only the third mode is possible without mode switching, for example, FIG.
, When a point 67 is set and input (clicked with a mouse or the like) in a region between the flaps Fa and Fb on both sides, a three-connection stair blade line 78 broken at two places is automatically generated and displayed on the screen. be able to.

The stay blade line 78 includes a middle line segment 78b (length adjusted) parallel to the product frame 30, a line segment 78a connected to the side 26b of the contour 26 at right angles, and the other side. A line segment 78c connected to the portion 26c at a right angle is connected in a polygonal line form. 24. When the mouse is clicked at an appropriate position between the flaps Fa and Fb in FIG. 24, the clicked position is set as a reference point (point) 69, and the product frame passes therethrough. 3
The intersections P1 and P2 of the virtual straight line 78b 'parallel to 0 and the virtual straight lines 26b' and 26c 'parallel to the sides 26b and 26c at the interval a are obtained, and the side 26b is determined from the intersections P1 and P2. , 26c, which are connected at right angles to the line segments 78a,
By generating geometric shapes 78c and displaying them collectively on a screen, a stitch line 78 in the form as shown in FIG. 23A is obtained.

The display of each line segment 78a, 78c can be set and input in advance to the same length a.
When the shape 11 is set, if the lengths of the two lines perpendicular to the two sides are separately set to, for example, a and b, respectively, the stitch blade line in a form as shown in FIG. 78 can also be generated.

Further, as shown in FIG.
Instead of above, a predetermined position of the contour line 26 (for example, the flap F
By specifying the position at the middle of the side (26c) of the side b of FIG. 2B by clicking the mouse or the like, the reference point (point) 69 'is set as the start point or end point as shown in FIG. It is also possible to generate and display the stay blade line 78. In this case, conceptually, a virtual straight line 78b 'passing through the point 69' clicked in the middle of the side portion 26c and parallel to the product frame 30, and a virtual straight line 26b parallel to the side portions 26b and 26c at the interval a. Intersection P1, with ', 26c'
P2 is calculated, and line segments 78a 'and 78c' connecting these points P1 and P2 and the side portions 26b and 26c at right angles are calculated. Further, a connection point P3 between the line segment 78c 'and the side portion 26c and a point 69 on the side portion are calculated. Line segment (virtual line 78b ') so that'
By performing the movement process on the coordinates while adjusting the length of the coordinate, finally, the stay blade line 78 starting from the initial point 69 ′ (or the end point) is displayed on the screen.

As shown in FIG. 26C, the flap F
A stitch blade line 78 connecting the side portions 26b and 26c between a and Fb through two break points, or a stitch blade line 78 "connecting through one break point as shown in FIG. It is also possible to display a screen so that another stitch line 79 is connected.Taking the stitch line 78 in Fig. 26A as an example, for example, the flaps Fa and F on the product frame 30 will be described.
By designating a point 69 displayed in advance (clicking with a mouse or the like) or setting a predetermined position on the product frame 30 arbitrarily (mouse clicking or the like) between the points b, the stitch blade line 78 is moved to the side portion. (Similarly regarded as a new side formed later), and the connecting line 7 is connected from the point 69 to the connecting line 78 at a right angle.
9 is obtained (FIG. 3 (c)). In this case, the stay blade 79
Is connected to a middle line segment 78 b of the stay blade line 78, and extends to the stay blade frame 34. In addition, as shown in FIGS. 3D and 3E, a hook blade 80 having a hook-shaped tip or a hook blade 81 bent at a set distance and a fixed angle is connected to the above-mentioned brush blade 78. It is good also as a form to make it.

When a stitch line is formed by clicking the mouse at an arbitrary position other than the selection candidate point 69, in order to specify in which direction the stitch line is to be drawn with respect to the clicked position, for example, a product shown in FIG. Clicking on a point Q1 on the frame 30 and then clicking on an arbitrary position Q2 specifies that the reference direction of the stay blade line to be drawn is a direction at a predetermined angle with respect to the straight line including Q1, for example, perpendicular to the straight line including Q1. Can be. In this case, more specifically, this Q
By clicking point 1 in FIG. 24A after clicking 1, the reference direction (horizontal direction in this case) of the stay blade line 78 is determined.

The selection of the blade shape in FIG. 16 and the dimension setting in FIG. 17 and the like are not required every time the position for forming the blade edge is specified.
As shown in FIG. 4 and FIG. 15, by returning to T4 via T10, it is possible to repeatedly specify the positions at a plurality of locations and collectively form a plurality of stitch blade lines having the same shape.
The selection of the shape, the dimension setting, and the selection of the formation position of the cutting edge line are repeated, and finally, a cutout image having the cutting edge line formed over the entire outer periphery of the contour line 26 as shown in FIG. 27 is obtained.

As shown in FIG. 28, when the horizontal stitch line 91 intersects with the vertical stitch line 90, the cut line adjusting means adjusts the horizontal stitch line 91.
Is formed so as to be divided before and after the vertical stay blade line 90, or so as to divide the vertical stay blade line 90 with the horizontal stay blade line 91 interposed therebetween. Also, as shown in FIG. 29, by forming the stay blade line 76, the screw insertion hole 81 (screw hole) that overlaps the stay blade line 76 is actually unavailable because it overlaps with the stay blade. Is deleted from the screen. When giving priority to the screw hole here, there is a method of bending the stay blade line 76 so as not to interfere with the screw hole (81), as shown in FIG.

Further, since the forming intervals of the stay blades are not always equal, it may be necessary to move a uniformly displayed selection candidate point. As shown in FIG. 12B, when an image movement command is specified for the selection candidate point 67 displayed based on the set value (the point 67 is made movable and moved by an input device such as a mouse or a keyboard). Specify (input) the amount, etc.), and select candidate points 67 according to the specified movement amount.
Selection candidate points 67a and 6
By displaying one of the displayed points 67a and 67b, the display of the selected point 67b remains, for example, and the point 67a is erased as shown in FIG. . At this time, the point 67 before the movement is displayed in a different color, for example, so that the presence or absence of the movement can be easily checked.

The die image data thus created can be partially modified by the application program 23b. Further, the image data can be stored in the storage device 22 (FIG. 1), and a development view (to which a stitch blade line or the like is added) can be printed out from the output device 19 based on the data. Also, instead of printing and outputting, a band blade (a cutting blade, a creased blade, a stitch blade) can be arranged along the contour line (including the dividing line for the fold) and the stitch blade line of the cut die image.
The development data with the cutting edge line etc. added is output to a slit forming device such as a laser cutting machine, so that the slit corresponding to the development data is formed on a template such as a plywood plate. The head unit can also be driven.

In the above-described example, the product frame, the stay blade frame (or the sheet frame), the veneer frame, and the like are displayed together with the outline, but these frame displays are not necessarily required. In addition to the contour line, only the mark image for specifying the stay blade forming position may be displayed. Also, when displaying a mark image to form a stitch blade,
The mark image is displayed not on the product frame, but on the sheet frame, on the stay blade frame, on the veneer frame or on any one of the frame lines on the virtual frame that is not displayed on the screen, or not on the frame. It is also possible to display on the contour line, or to display in a dotted or random manner around the contour line.

Also, as shown in FIG.
Is stopped so that it is not directly connected to the side 26a of the contour line or the stub blade frame 34, so that the end of the stub blade line 76 is positioned close to the side 26a or the stub blade frame 34.・ Can be displayed. In this case, the scraps surrounding the punched sheet product and separated by the stay blade are partially connected to each other, but in the process of exclusion, the connecting portions are cut and individually cut or separated. If it is more convenient not to divide at the time of exclusion, it is also possible to perform exclusion in a connected state of the waste portion, and to divide later, or to fold without dividing.

Further, as shown in FIG. 31, it is also possible to superimpose the shapes of the stitch blade lines described above, in other words, to display the screen in a complex combination. For example, there is a selection screen for selecting the shape 3 and the shape 11 in FIG. 16 in a multi-layered (composite) manner, for example, when there are a plurality of individual selection areas, and "3" and "11" are numerically input to the respective selection areas. Alternatively, the user clicks the area of shape 3 on the screen with the mouse, and further clicks the area of shape 11 to set the multilayer mode. As a result, for example, as shown in FIG. 31 (a), a straight line is connected to the inclined side portion 26b and extends to the side portion 26c or the stepping blade frame 34, and a bending portion at the tip end is provided. 92
It is possible to obtain a steeper blade line form having c. FIG.
The cutting edge line 93 shown in FIG.
6c at right angles to each other, and
c is automatically generated. Figures (c) and (d)
16 can be said to be, for example, a layered combination of shapes 0 to 4 and shapes 6 to 10 in FIG. A blade bending portion 94c or 95c may be added.

The functions of the die making system 1 described above are essentially realized by the programs stored in the storage device 22. Therefore, if these programs are recorded on a recording medium such as a floppy disk or CD-ROM, the above-described FDD 25 or CD-ROM drive 26 can be used in a computer system having a hardware configuration substantially similar to that shown in FIG. By installing each program in the storage device 22, the function of the die cutting system 1 can be ported to the computer system.
