Abstract

PURPOSE:To attain the output of the hole working data on an entire die plate with a single output operation and to shorten the output time of the hole working data by adding a file name to each late and outputting the intermediate data on the entire die plate. CONSTITUTION:The output order of plates PLT is decided by a processor 11a for the batch output of the intermediate data on the entire die plate. then a file name is added to each PLT at the batch output in accordance with the output order of the PLTs. Thus the intermediate data on the entire die PLT is outputted. At the same time, the output order of split plates is also decided in case these split plates are used. Then a file name is added to each split plate and the intermediate data on all component split plates are outputted.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for outputting hole machining data, particularly for mold CAD.
The present invention relates to a hole machining data output method that outputs intermediate data for creating NC data for hole machining each plate after designing a mold made of a plurality of plates using an ICAM system.

<Prior art> A progressive die or a molding die is composed of multiple plates, and several press punches (progressive die) or cavities/cores, runners/gates, water holes, etc.
The above molding die is provided. Note that each plate is fixed with mounting bolts and other parts.

Mold C for designing such progressive die or mold die
The AD/CAM system is a mold design system (CAD system) that designs molds by itself, as shown in Figure 6.
a, and an NC data creation system (CAM system) lb that creates NC data 2 for mold processing. In addition, each system is 1s.

(b) may be configured with separate devices, but in reality, a system is constructed as appropriate by loading a system program for mold design and a system program for creating NC data into one computer.

In such a mold CAD/CAM system 1, for example, a progressive die design system (CAD system) l
a: interactive product placement based on the input product shape;
The number of stages, pitch, etc. are designed (blank layout processing), then the punch shape or die shape is created interactively (strip layout processing), and each plate that makes up the progressive die is automatically designed by die concept processing, and CAM The system 1b receives shape data and processing information (intermediate data) of each plate automatically designed by CADla, and creates and outputs NC data. still.

If the plate number is a progressive die (see Fig. 7 (n)), it is divided into an ox-shaped plate and a lower plate with the dividing surface SPF as the boundary, and the upper plate is numbered with a positive number in order, for example. TeN
o, 1. No, 2. It is defined as...

The plates of the lower mold are numbered with negative numbers starting from N010.
o −1+ N o , 2 + . . . are defined. In addition, if it is a mold mold (see Figure 7 (b)), it is divided into a fixed plate and a movable plate with the dividing surface SPF as the boundary, and the fixed plate is numbered with a positive number in order from the dividing surface SPF. No, 1. No, 2. ..., and the movable plates are numbered No. 1, -1, and No. 2, with the nearest plate from the dividing plane SPF being N010, and negative numbers assigned in order.
+... is defined.

By the way, the intermediate data for hole machining of each plate automatically designed by the mold concept processing was outputted according to the processing flowchart shown in No. 8@. That is, in the hole data output mode, specify the plate number to be output from the list of designed plates (step 201).Then, the system determines whether the specified plate is split or not (step 202) - split If it is not a plate, the process jumps to step 204, and if it is a split plate, a question for specifying the split plate for outputting intermediate data is displayed, and the operator is asked to specify a predetermined split plate (step 203). Interactively specify the origin of the output data, the position of the hole machining reference point, and the machining direction (machining from the surface of the plate or from the odor (step 204)), and select an external output medium (paper tape, floppy disk, etc.). If you specify (
Step 205), intermediate data for hole machining of the specified plate (or split plate) is output (Step 205).
06), if there is another plate to be output next, the process from step 201 is repeated (step 207).

<Problems to be Solved by the Invention> However, in the conventional hole machining data output method, operations for outputting intermediate hole machining data for each plate or each split plate (see Fig. 8) are required. In order to perform the operations from step 201 to step 207, in order to output all the plates of the entire mold, the same operation must be repeated multiple times, resulting in poor operability.

Furthermore, after the output operation for one plate (after step 205), it is necessary to wait until the data output for that plate is completed in step 206 before outputting the next plate. There was a problem that it took a lot of time.

From the foregoing, an object of the present invention is to provide a hole machining data output method that can output hole machining data of a plate for the entire mold with a single output operation.

<Means for solving the problem> Figure 1 shows a CAD/CAD system for progressive die design to which the present invention can be applied.

A floppy disk stores a system program for creating NC data, a floppy disk 16c stores generated NG data, a printer 17, and a printing paper PRP. The output order when outputting intermediate data of the entire mold plate at once is set by a parameter.

In the tablet device 1113, 13a is a tablet surface, 13b is a menu table, and 13C is a tablet cursor. A menu table 13b is pasted on the tablet surface 13a, and various items and data can be entered by clicking on a predetermined item written on the menu table 13b with the tablet cursor 13C.

Note that the output order of the plates of the entire mold when outputting intermediate data all at once is set by parameters stored in the RAM 11c together with the mold design system program. That is, when outputting the intermediate data of each plate all at once, ■ start with the upper mold plate closest to the dividing surface, ■ then start with the lower mold plate closest to the dividing surface, and ■ plates with splits are on the left side (those with small Y coordinate values). The parameters are set to output from.

FIG. 3 is a flowchart of the process of the present invention. below.

Hole machining data output processing according to the present invention will be explained according to the flowchart in FIG. It is assumed that the plate list LST and the shape of the plate PLT automatically designed by the mold concept processing are drawn on the CRT of the graphic display device 12.

After checking the machining data output section T5 (Fig. 2) with the tablet cursor 13c, the operator selects "hole data J item TH".
Big a (step 101).

Due to the big of "hole data" item THa, processor L
la asks the CRT which plate's hole machining data is to be output (Plate No. = J).In response to this question, ) If you want to output hole machining data, refer to the plate list LST drawn on the CRT, enter the plate number (for example, "2" for a punch plate), and output the hole machining data of the entire plate of the mold. If you wish to output all of
(You may also press the NLJ key).

Processor l] a is the question text (“Plate No., = J
) to judge the input from the operator.Step 1
02) If the plate number is input, the conventional hole machining data output process is performed (see FIG. 8).

On the other hand, if the "input" item is picked, a question text for setting output data shown in FIG. 4 is displayed. That is.

Processor lla determines (i) the origin (X.,
Y, ) and (jj)rBp= J, the position of the hole machining reference point is set at the four corners of the plate (Fig. 7, UL (upper left),
UR (upper right), LL (lower left), LR (lower right)) - (Group) IN/R = J is used to process the plate from the front (enter "N") or from the back. Processing (r
Input RJ) or the machining direction. In response to the question, the operator selects 1, for example, the origin of the output data (10, O).
, machining reference point (BP=LR), machining direction (N/R=N)
is specified (step 1.03). When the origin, reference point, and machining direction are specified, the processor Ila first displays a question on the CRT asking about the external output medium. When the operator selects floppy by pressing, for example, the function key rF"IJ in response to the question (step 104), the operation for outputting the hole machining data all at once ends. - Output at once When the operation for is completed, the processor Ila changes i→1 (Step 105), and determines whether the first plate is cracked or not, which is determined based on the plate output order rules ■ and ■ stored in the RAM 11c. (Whether it is split plate configuration or not) Determine step 106)
If there is no crack, output the hole machining data of the first plate with a file name (for example, rHOiJ) (step 107), and perform the processes from step 112 onwards. If the first plate is broken, the processor lla changes j→1 (step 108), and the j-th split plate is determined based on the output order rule for split plates stored in the RAM 11c. The hole machining data is output with a file name (for example, rHOl-jJ) (step 109), and then the processor lla determines whether all the split plates of the first plate have been output (step 110). If it's not output.

j+l→j Then, step 111), repeat the process from step 109 onward. On the other hand, if all the plates have been output, that is, if the output of the first plate is completed, the processor Ila will output all the plates of the entire mold. It is difficult to judge whether the output has been output (step 112), and if not all have been output.

i+1→i, step 113), and repeat the processing from step 106 onwards.On the other hand, if all are output, the hole machining data output processing is ended.

In 1 and above, the case of progressive die was described, but
In the case of a mold mold, the mold base is similarly designed using the mold design system program, starting with the fixed plate closest to the splitting surface, then starting with the movable plate closest to the splitting surface, and starting with the split plate. Left side (Y coordinate value)
The configuration is such that parameters are set for the order in which the plates are output from Jl-Small Products), and intermediate data of the plates for the entire mold is output by attaching a file name to each of the 5 plates according to the order in which the plates are output in batch output. do.

<Effects of the Invention> According to the present invention, the output order of each plate is determined when the intermediate data of the plates of the entire mold are output at once, and the output order of the plates is determined in accordance with the output order of the plates when outputting the intermediate data of the entire mold at once.
Since the configuration is configured to output intermediate plate data for the entire mold by assigning a file name to each plate, it is possible to output the hole machining data for the entire mold plate with a single output operation. The time required to output the entire hole machining data can be shortened.
