DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration diagram of a die machining data allocation apparatus 1 according to the present embodiment.
[0017]
First, the template will be explained. In this example, the template refers to data including template mold machining data and a line segment to which the template mold machining data is assigned.
[0018]
Template mold processing data refers to mold processing data registered as part of the template data. Since the die machining data assigned to the part figure includes die outer shape information, rotation information, and position information, NC data can be created by converting the die machining data. .
[0019]
Referring to FIG. 1, the die machining data allocating device 1 is composed of a computer and includes, for example, a computer main body (including a storage device) (not shown), a display unit 3, an input / output unit 11, and the like. ing.
[0020]
The die machining data allocation apparatus 1 includes a display unit 3 for displaying a figure of a drawing and the like, and a CAD / CAM unit 5 for editing the figure, creating NC data, and the like. The drawing created by the CAD / CAM unit 5 and NC data are stored in the CAD / CAM data file 7.
[0021]
The CAD / CAM unit 5, the input / output unit 11 for inputting / outputting necessary data, and the control unit 13 for managing the allocation of mold machining data using a template are coupled by a link control unit 9. ing. By having this link relationship, the control unit 13 can read and write CAD / CAM data from the CAD / CAM data file 7.
[0022]
The control unit 13 uses a template to assign a template die machining data to a part graphic, a template storage management unit 17 for managing the template storage, etc., and a die machining assigned to the part graphic. An NC data creating unit 19 that creates NC data from data or the like is provided.
[0023]
The allocation management unit 15 includes a template search unit 21 and a die machining data allocation unit 23.
[0024]
The template search unit 21 searches for and reads a template from a plurality of templates registered in the template database 29.
[0025]
The mold machining data allocating unit 23 performs a process of allocating template mold machining data to a part figure using the template searched by the template search unit 21.
[0026]
The template accumulation management unit 17 includes a manual editing unit 25 and a template registration unit 27.
[0027]
If the die machining data to be assigned to the part graphic is not registered as a result of the search by the template search unit 21, normal die machining data is automatically assigned to the part graphic. Then, the manual editing unit 25 creates a template by, for example, manually editing mold machining data automatically assigned to part graphics.
[0028]
The template registration unit 27 stores the template edited and created by the manual editing unit 25 in the template database 29. Thereby, this template can be used from the next time.
[0029]
The NC data creation unit 19 creates NC data from the die machining data assigned to the part graphic and stores it in the NC data file 31.
[0030]
The data transmission unit 33 reads NC data from the NC data file 31 and stores it in the CAD / CAM data file 7 and transmits the data to the NC processing machine 37 via the communication cable 35, for example.
[0031]
A method for registering a template in the template database 29 will be described with reference to FIG.
[0032]
When NC machining a part with a mold, mold machining data is assigned to the part graphic of this part on the display screen. Normally, die machining data is automatically assigned to a part figure, but the automatically assigned die machining data may not be appropriate for product processing. In this case, the die machining data is again assigned to the part graphic, but is registered in the template database 29 so that the die machining data assigned here can be reused.
[0033]
As shown in FIG. 2A, when the line segments to which the die machining data is assigned are the line segments L1, L2, and L3, the graphic formed by these line segments is extracted.
[0034]
FIG. 2B shows the storage format of the line segments L1, L2, and L3 in the template database 29. When the straight traveling direction is 0 degree and the next element (line segment) extends rightward in the traveling direction, it is defined as a negative angle. When the next element (line segment) extends to the left, it is defined as a positive angle. Accordingly, the line type is defined as LINE and the increase angle is defined as -90 degrees for the line segment L1 and stored. For the line segment L2, the line type is defined as LINE, and the increase angle is defined as -60 degrees and stored. For the line segment L3, the line type is defined as LINE, and the increase angle is defined as +60 degrees and stored. Since these line segments are connected, the shape is defined by these data. As a result, for example, even if a part of a part graphic is different from the size of the shape included in the template, a similar graphic can be handled. Here, for example, when there are line segments LA, LB, and LC, the length is different from the line segments LA, LB, and LC, and the line segments L1, L2, and L3 are different in length. Includes shapes with the same angle.
[0035]
FIG. 2C shows a state in which the template mold machining data KT1 and KT2 are assigned to the shape included in the template. The template mold machining data KT1 is stored in association with the line segments L1 and L2. Template mold processing data KT2 is stored in association with line segment L3.
[0036]
With reference to FIG. 2C and FIG. 2D, the association between the line segment of the shape included in the template and the template mold processing data will be described. The template mold processing data KT1 has a rectangular shape type, and the outer shape of the template mold processing data KT1 is defined by the end points of the line segments L1 and L2. That is, the definition points P1 (V1X, V1Y), P2 (V2X, V2Y), P3 (V3X, V3Y), and P4 (V3X, V1Y) are stored in the memory. Further, the value 1 of the overhang amount H1 is stored.
[0037]
The shape type of the template mold machining data KT2 is a triangle, and the outer shape of the template mold machining data KT2 is defined by a line segment L3 and a virtual perpendicular including the end point of the line segment L3. That is, the definition points P3 (V3X, V3Y), P5 (V4X, V4Y), and P6 (V3X, V4Y) are stored in the memory. Further, the value 1 of the protrusion amount H2 is stored.
[0038]
In addition, a rotation template, which is data obtained by rotating a template stored in a memory, and a symmetric template, which is line symmetric data of the template, are created and stored in the template database 29. In the case of the shape of rotation and symmetry and a combination thereof, the rotation template, the symmetry template, and a combination thereof are used to assign to the part figure.
[0039]
Here, with reference to FIG. 3 to FIG. 14, an operation of assigning template mold machining data will be described.
[0040]
In step S301, the part figure W is displayed on the display unit 3. FIG. 5A shows a state in which the part graphic W is called up on the display screen GH. In this example, the part figure W includes line segments LN1, LN2, LN3, LN4, LN5, LN6, LN7, LN8, LN9, LN10, LN11, LN12, and LN13.
[0041]
In step S303, die machining data is automatically assigned to a part figure W of a part to be die-molded from a workpiece.
[0042]
FIG. 5B shows a result of assigning a normal die without template registration when the die machining data is assigned to the part graphic W in step S303.
[0043]
Mold processing data KG1, KG2, KG3, KG4, KG5, KG6, KG7, KG8, KG9, KG10, KG11, KG12, KG13, and KG14 are assigned to each line segment of the part figure W.
[0044]
In step S305, the die machining data is manually assigned, and it is determined whether or not to register the assigned template die machining data. If it is determined in step S305 that template mold machining data is to be registered, the process proceeds to step S307. When it is determined in step S305 that no template mold machining data is registered, the process ends.
[0045]
In step S307, the part to which template mold machining data is allocated is deleted from the mold machining data automatically allocated in step S305.
[0046]
FIG. 6A shows a state in which the die machining data automatically assigned to the tip of the portion to which the template die machining data is assigned is deleted. As a result, the die machining data KG7 assigned to the line segment LN6, the die machining data KG8 assigned to the line segment LN7, the die machining data KG9 assigned to the line segment LN8, and the die assigned to the line segment LN9. Die machining data KG10, Die machining data KG11 assigned to line segment LN10, Die machining data KG12 assigned to line segment LN11, Die machining data KG13 assigned to line segment LN12, and Allocation to line segment LN13 The obtained die machining data KG14 is deleted.
[0047]
In step S309, template mold processing data is newly allocated, for example, manually to the portion where the mold processing data automatically allocated in step S303 is deleted in step S307.
[0048]
FIG. 6B shows a state in which template die machining data is assigned to the part erased in step S307 of the part graphic W. Template mold processing data TK1 is allocated in association with line segments LN6 and LN7. Template mold processing data TK2 is allocated in association with line segment LN8. Template mold processing data TK3 is allocated in association with line segment LN9. Template mold processing data TK4 is allocated in association with line segment LN10. Template mold processing data TK5 is allocated in association with line segments LN11 and LN12. Template mold processing data TK6 is allocated in association with line segments LN12 and LN13. Template mold processing data TK7 is allocated in association with line segment LN13.
[0049]
In the above-described association, for example, by selecting a line segment with a mouse when assigning template mold machining data, the instructed line segment is associated with the template mold machining data.
[0050]
Further, a reference point is selected and the data of this reference point is stored in the template database 29 simultaneously with the template data. Thereby, the arrangement position of the die machining data with respect to this reference point is determined and registered. Then, it becomes a reference point when assigning the template die machining data next time. In this example, the reference point BP1 is set as shown in FIG. 6B, for example. Thus, for example, in the case of template mold machining data TK4, the positional relationship between the mold reference point BP defined in the template mold machining data TK4 and the reference point BP1 is determined, and the next template mold data is assigned. An allocation position for the reference point BP1 is determined.
[0051]
In the process of step S311, an area for template registration is designated, and then the screen is changed to a mode screen for registering a template. By designating this area and changing the mode, the data registered in the template is separated from the part graphic W and the die machining data assigned to the part graphic.
[0052]
FIG. 7A shows a state where an area for template registration is designated. For example, a button BN1 for designating a template area is pressed and an area EA for template registration is designated with the mouse.
[0053]
FIG. 7B shows a state where the display screen GH has been changed to the template registration mode. As a result, line segments LN6, LN7, LN8, LN9, LN10, LN11, LN12, and LN13 are displayed on this display screen GH, and template mold machining data TK1, TK2, TK3 associated with these line segments are displayed. , TK4, TK5, TK6, and TK7 are displayed. The shape displayed here and the template mold processing data associated with the line segment included in the shape are stored in the template database 29 as template data. The shape is matched with the part graphic when the mold processing data is allocated to the part graphic next time, and the template mold processing data is allocated to the corresponding part.
[0054]
In step S313, when the template mold machining data assigned to the line segment is assigned, the set reference point is changed.
[0055]
FIG. 8A shows a screen for changing the allocation reference point of the template die machining data. For example, when the tool machining data assignment reference change button BN2 is pressed, the menu PM is displayed.
[0056]
In this example, a case where the reference point of the template mold processing data TK4 is changed will be described, for example.
[0057]
FIG. 8B shows details of the menu PM. For example, since the template mold processing data TK4 is a single mold, the button TB for changing the reference position is pressed. As a result, the reference point BP1 set ahead of the template die machining data TK4 is displayed on the display screen GH.
[0058]
As shown in FIG. 8A, the initially set reference point BP1 is changed to a new reference point that can be appropriately moved with respect to the expansion and contraction of the line segment LN9. Accordingly, even if the line segment LN10 moves to the left and right on the screen due to the expansion and contraction of the line segment LN9, the new reference point also moves, so that the template mold processing data TK4 can move to an appropriate position.
[0059]
In step S317, a template name is registered by inputting a template name, a used plate thickness range, automatic allocation conditions, rotation recognition, and the like.
[0060]
FIG. 9A shows a screen for template registration. For example, the template registration button BN3 included in the menu MU displayed on the display unit 3 is pressed. As a result, the template registration screen TG is newly displayed.
[0061]
FIG. 9B shows details of the template registration screen. Enter the template name TN in the column for entering the template name. The minimum value TMIN and maximum value TMAX of the used plate thickness are entered in the column for entering the used plate thickness range.
[0062]
Check both DLs in the column for determining automatic allocation conditions. Check the recognition column KN for automatic allocation rotation recognition. Then, a template is registered by pressing the registration button TB. As a result, the template is newly registered in the template database 29, and the die machining data of this template can be assigned to the same or similar part graphic.
[0063]
In the process of step S319, the priority of the registered template allocation order is determined.
[0064]
FIG. 10A shows a screen for instructing template assignment priority. When the priority order determination button BN4 of the menu MU is pressed, a screen PY for newly determining the priority order is displayed.
[0065]
FIG. 10B shows details of this screen PY. On this screen, the priority for using the template registered this time is determined and the apply button TB2 is pressed. As a result, the mold shape of the template is preferentially assigned.
[0066]
In step S321, template setting is completed and template registration is also completed.
[0067]
Thereby, the template can be used next time.
[0068]
FIG. 11A shows a process of assigning mold machining data to a product graphic using a registered template. For example, the die machining data assignment button BN5 included in the menu MU is pressed. Thereby, the screen SG is displayed. In this example, the case where the line segments LN2, LN4, LN6 and the line segment LN13 included in the product graphic are equally long is shown.
[0069]
FIG. 11B shows details of the screen SG. On this screen SG, for example, the template use column TC is checked and executed.
[0070]
FIG. 12 shows a state in which the die machining data including the template is assigned to the product graphic in the above execution. Mold processing data of the template TP registered in the work figure W is assigned. In this example, the template mold processing data TK1 and TK7 are also assigned to be longer corresponding to the lengths of the line segment LN2, the line segment LN6, and the like.
[0071]
FIG. 13A shows a case where the line segment LN7 included in the product graphic is long.
[0072]
As shown in FIG. 13B, for example, the template usage column TC is checked on the screen SG for execution.
[0073]
FIG. 14 shows a state in which the die machining data including the template is assigned to the product graphic in the above execution. Mold processing data of the template TP registered in the work figure W is assigned. In this example, the template mold processing data TK1 is also allocated to be extended horizontally in response to the line segment LN7 extending horizontally.
[0074]
The present invention is not limited to the above-described embodiments of the invention, and can be implemented in other modes by making appropriate changes.
[0075]
FIG. 15 shows a CD-ROM as an example of a storage medium storing a control program for controlling the above-described die machining data allocation device 1. The CD-ROM is a computer-readable storage medium storing a control program for controlling the die machining data allocating device 1 by a computer.

【The invention's effect】
As described above, according to the present invention, template mold machining data can be automatically assigned to all or part of a part graphic, and the NC data creation time can be reduced.
[0077]
Further, since the template mold processing data is automatically assigned to the part figure, it is possible to prevent a product defect due to an assignment error.
[0078]
Since individual template mold machining data included in the template can be transformed into similar mold machining data, there is an effect that even when a part graphic template is assigned to a part similar to the template, it can be automatically assigned. .
[0079]
By setting the reference position to the shape included in the template, there is an effect that it is possible to cope with the case where the position where the template mold machining data is allocated is moved.
[0080]
By registering a rotation template and a symmetric template, template mold processing data can be assigned even when all or part of a part graphic is rotated or inverted.
