Abstract

PURPOSE:To easily add or correct process information on a repeat figure by providing a repetitive additional processing means which adds the same information as information added to an original figure to another figure repeatedly. CONSTITUTION:A process information adding process part 10 discriminates a figure is a repeat figure or not and when it is discriminated that the figure is the repeat figure, process information is added to the original figure regarding the specification of a master figure or a slave figure. When approach information 19 is added to, for example, the master figure F4, a repetitive process is performed and the approach information 19 is added to other figures F5 and F6 similarly; and the information to which the process information is added is stored as program generation information in a storage part 11 as well as figures other than the repeat figure. Consequently, the adding process of the process information is facilitated and speeded up and the information after the process information is added is easily and speedily corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an automatic programming device that automatically generates NC programs for various processing mechanisms.

(Conventional technology) Various processing machines such as laser processing machines, wire cut electrical discharge machines, and turret punch press machines require CAD.
(Computer Aided Design) and CAM (Co+computer Aided Manu)
Automatic programming devices are often used in combination with CAD (factoring) to generate NC programs for numerically controlling machines using CAM in order to process machining figures designed using CAD.

Here, CAD generally has a copy function and a repeat function, and figures for repeatedly processing the same shape can be easily designed by copying or repeating a parent drawing.

The copy function is a function that transfers the original drawing to another position so that all product figures have individual shape data.

The repeat function is a function that has shape data only for the parent figure, expresses each child figure by its transfer position, and defines a large number of product figures only by specifying the transfer position.

On the other hand, C inputs machining figures and creates NC programs.
AM manually processes drawings designed using the copy or repeat function, adds processing information to each figure, and generates an NC program to process all figures.

However, since the automatic programming section itself configured in CAM does not have a function similar to the copy function or repeat function, the automatic programming section adds processing information to each individual figure individually [7, NC to process individual machining shapes with various machining information attached
It is about generating a program.

The same applies to an automatic programming device that is not based on CAD-CAM, but is one in which a simple graphic processing device and an automatic NC program generation function are attached to an NC device that controls a processing machine.

Therefore, in the conventional automatic programming device, a figure created using a repeat function is converted into individual figures, individual pressure information is added to each figure, and an NC program is generated.

Also, when it becomes necessary to modify a figure created using the repeat function, you can either start over from the CAD side or use the NC program! 4: It was necessary to modify each of the individual figures that had been previously generated, and to generate an NC program for the revised figures.

An example of pressure information added to machining shape data is as follows:
For example, in laser processing, as a preliminary process before cutting the product, the pierced earring and this pierced earring are shaped into the product (Masochi needle-shaped figure consisting of connecting line segments, processing speed for each processing position, laser output conditions, etc.). (Cows are an example.

(Problem to be solved and attempted by the invention) However, in the conventional automatic programming device as described above, even if there are two repeat figures C, individual number machining information is added or modified in the same way as other figures. For figures that include a large number of one-nobit figures, processing information must be added at 7N+.

In addition, when modifying a figure from the CAD side, the automatic programming device must be activated from the initial state, so it is easier than modifying the figure, but it takes a lot of time to generate the NC program. There was a problem in that it required

Therefore, an object of the present invention is to provide an automatic programming device that can easily add or modify processing information for repeat figures.

[Structure of the Invention] (Means for Solving the Problems) The present invention for solving the above problems expresses the relationship between a parent diagram and a plurality of child diagrams using its reference position and shape data of the parent diagram. In an automatic programming device that inputs machining shape data including repeated shapes, adds pressure information to each shape, and generates NC program data, for each repeat shape, one of the parent diagrams or child diagrams.
By adding processing information to the original drawings related to one designation,
The present invention is characterized in that a repetitive addition processing means is provided for repeatedly adding the same information added to the original figure to other figures.

Also, regarding the relationship between the parent diagram and multiple child diagrams, input machining shape data including repeat shapes that express the child diagram as its reference position and the shape data of the parent diagram, and add machining information to each shape. In an automatic programming device that generates NC program data, when modifying the information by adding processing information to the repeat figure, the information of the original figure related to one more designation of the parent figure or child figure. The present invention is characterized by the provision of an iterative correction processing means for repeatedly correcting other figures so that the same information as the original figure is obtained by the correction.

(Function) In the automatic programming device of the present invention, it is recognized that a repeat figure in a processed figure should originally be a form in which the exact same relationship is transferred to another position, and here a new repeat is simply referred to as a repeat figure. It is defined as not only showing the same shape, but also having the same shape and showing the same processing, and adding information to the original drawing related to the designation of one of the parent drawings or child drawings, or adding information to the original drawing or By modifying the information added (N1), it is now possible to add or modify other figures so that they have the same content as the original figure.

(Example) In FIG. 1 showing an example of the present invention, 1 is a CAD-
1 shows an automatic programming device consisting of CA, M;

The CAD 2 is equipped with a copy function 3 and a repeat function 4, similar to the CAD onboard the ship. An operating device w7 including a keyboard 5 and CR, T6 is connected to the CAD2.

On the other hand, the CAM 8 of this example has various production management functions, as well as a processing figure data setting section 9 that inputs the figures created by the CAD 2 and stores the settings, a processing information addition processing section 10, and the processing section 10. It includes a program generation information storage section 11 that stores information to which machining information has been added as program generation information, an NC program generation section 12, and an NC program output section 13.

The program generation information storage unit 11 develops each figure and holds each figure as individual data, even regarding repeat figures. However, in this example, a repeat flag RP is provided in the program generation information storage section 11, and it is stored that a repeat graphic is a repeat graphic.

A correction processing section 14 is connected to the processed figure data setting section 9 and the program generation information storage section 11.

FIGS. 2 and 3 are explanatory diagrams of the copy function 3 and repeat function 4 of the CAD 2.

The copied data is the figure F1. F2. For F3, Fl　(Pi, F2.F3) F2 (1’4.F5.F6) F3 (F7.F8.F9) It is expressed as , and there is actual data.

Also, the repeated data is the figure F4. F5, F6
For F4 (, Plo, pH, F12.F5.F6) F5 (
F4. Ll, ) F6 (F4.F2) and position data Ll for the parent figure (F4).

There is a relationship of child diagrams (F5.F6) indicated by F2.

Therefore, in CAD2, for example, the fourth
It is possible to create the processed shape of a product as shown in the figure using the copy function 3 and repeat function 4. The product shown in FIG. 4] 5 has a shape W f (W+, W2
,...) is shown as an example of laser cutting. Here, it is assumed that the cut shape Wi is created using the repeat function 4.

FIG. 5 shows a graphic processing system of the automatic programming device 1 comprising the above-mentioned CAD-CAM.

In step 501, the shape shown in FIG.
It is created in step D2, and in step 502, it is input to the CAM 8 and set and stored in the processing figure data setting section 9.

Therefore, in step 503, the processing information addition processing unit 10
In step 504, it is determined whether or not the figure is a repeat figure. If it is not a repeat figure, the process moves to step 504, and processing information is added to each individual figure. As described above, the processing information includes approach information 16 as shown in FIG. 6, laser output conditions, and the like. Figure F1 shown in FIG. ．． F2.
Since F3 is a copy figure shown in Fig. 2, processing information (16) is added to figure F1, and then processing information (17) is separately added to figure F2, and so on for each figure individually. It is processed. The information added to the processing information is stored in the storage unit 1 as program generation information.
1 and stored sequentially.

Next, in step 505, it is determined whether all the figures have been processed, and the process returns to step 503 until all the figures have been processed.

On the other hand, if it is determined in step 503 that the figure is a repeat figure, the process moves to step 506, where processing information is added to the original figure related to the designation of either the parent figure or the child figure. In the example shown in FIG. 7 corresponding to FIG. 3, for example, when approach information 19 is added to the parent diagram F4, repeated processing is executed in steps 507 and 508,
Other figures F5. Similarly for F6, approach information 1
9 is added.

The information to which processing information has been added for the repeat figure is stored in the storage unit 11 as program generation information, similarly to figures other than the repeat figure. However, for convenience of later processing, the fact that the repeat graphic is a repeat graphic is stored in the repeat flag RP.

Therefore, in the automatic programming device 1 of this example, steps 507 and 508 are repeatedly processed for each repeat figure, so if machining information is added only to the shape Wl in FIG. 4, for example, other shapes w2, w3, etc. ...
Processing information is automatically added to the date.

Next, when it is determined in step 505 that machining information has been added to all the figures, the process moves to step 509, where the NC program generation section 12 generates an NC program.

The generated NC program operates a work clamp device (not shown) that grips the workpiece so that each shape is sequentially cut under predetermined conditions following the approach information added, and the laser and assist Indicated by the command to control gas.

In step 510, it is determined whether there is a modification command, and if there is no modification, the NC program generated from the NC program output section 13 is outputted to a predetermined machine in step 511, or if there is a modification command, modification processing is performed in step 900. to move to.

FIG. 8 is an explanatory diagram of a modified example. 8eJ(a) is the 4th
This is an enlarged view of the shape Wfi in Fig. 8(b).
) is an example in which each edge portion in FIG. 8(a) is changed to R.

In FIG. 9 showing the contents of the correction process, step 901
Now let's determine the mode. The modes here are CAD mode and CAM mode, and when the CAD mode is selected, the process moves to step 902.

In step 902, the original drawing set in the machining figure data setting section 9 is referred to, and the figure is corrected appropriately using the functions of CAD2.In step 903, the processes shown in step 503 and subsequent steps in FIG. 5 are executed, and the NC program is newly generated. In this respect, it is the same as the conventional example, and although the rest is automatic, a considerable amount of time is required to generate the NC program.

On the other hand, if the CAM mode is selected in step 901, the process moves to step 904, where the program generation information for the modified part is read out from the storage unit 1, and the repeat flag RP is referred to, and in step 905, the repeat figure is It is determined whether or not.

If it is determined in step 905 that the figure is a repeat figure, the process moves to step 906, where correction details for the figure or processing information are entered for either the parent figure or the child figure, and in step 907. Automatically correct all repeat shapes repeatedly.

Therefore, in this example, if the repeat figure is corrected, for example, in FIG. 8(b) using one figure Wi shown in FIG. 4 as the original figure, all the remaining repeat figures will be automatically corrected. Correction time can be shortened.

The same applies to modification of processing information such as approach information.

If it is determined in step 905 that the figure is not a repeat figure, then in step 908 individual corrections can be made for each individual figure.

In step 909, it is determined that all corrections have been completed, and the correction process is ended.

As described above, in the automatic programming device 1 of this example, the machining information addition processing unit 10 shown in FIG.
Since the correction processing unit 14 is provided with a repeat correction function of steps 906 and 907 in FIG. This is useful in laser processing that requires the use of many repeat functions.

FIG. 10 shows another example of repeat figures.

(a) The figure shows angled linear machining (LAA), (b) the figure shows circular arc machining (ARC), (c) the figure shows circumferential machining (BHC), (
Figure cl) shows an example of lattice processing (GRID), and figure (e) shows an example of single-shot processing (SINGL).

In the above embodiment, an example of an automatic programming device using CAD-CAM is shown, but other automatic programming devices such as those not called CAD-CAM or automatic programming devices that are linked to an NC device are also applicable. The same applies.

Further, in the above embodiment, an example of laser machining is shown, but the same applies to press machining and wire cut electric discharge machining.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in any appropriate manner by making appropriate design changes.

[Effects of the Invention] As described above, the present invention defines a figure that repeats the same figure and the same processing as a repeat figure, and for the set repeat figure, it can be used to create other figures by adding processing information of the original figure. The contents are the same for the information used to generate the NC program, and other figures are also modified in the same way by modifying the original diagram for the information used to generate the NC program, making it easy and quick to add machining information.
