Abstract

PURPOSE:To reduce the setting time of copying data and improve the efficiency of metal mold machining by superposedly displaying plural copying zones on a CRT simultaneously and judging the propriety of each copying zone, existence of being left uncopied, and excessive superposing of zones. CONSTITUTION:From a copying zone memory part 11 in which plural copying zones (a), (b), (c), (d) which are set on a model 1 are stored, e.g., zones (a) and (c) are selected and designated by a copying zone display setting part 12. Then, the software limit information on the designated zones (a), (c) is taken out of the memory part 11 by a copying zone display controlling part 13, to send out the signals of the whole picture plane informa. tion including these. These signals are received by a copying zone display part 14 to superposedly display the whole picture image of the model 1 and the software limits indicating the zones (a), (c), on a CRT 15, thereby, preventing existence of being left uncopied or wasteful copying and improving the efficiency of metal mold machining.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a copying control device, and is intended to be able to quickly and accurately copy a model, and is applicable to copying machines, coordinate measuring machines, and digitizers. It is useful.

<Prior Art> In order to imitate the model 1 shown in a perspective view in FIG. 2, as shown in FIG. 3 shown in a plan view, four areas a,
The pattern is divided into areas b, c, and d, and copying is performed for each area. To designate each region, divide it into sections with different shapes using software limits or software potential lines.

Among these, the software unilimit 2 is a method of specifying an area A (area indicated by hatching) using straight lines LYP, LYN, LXP, and LXN, as shown in FIG. 4, for example. The software potential line is, for example, as shown in FIG. 5, the coordinate point LW1. LW2. -,
This is a method of specifying region B (region indicated by /X latching) by giving several points and surrounding them with line segments connecting the points.

Areas a and b specified as described above.

The copying methods for c and d are different.

Model 1 is copied by performing multi-step copying in which the process of copying one area is completed and then copying the next area.

Conventionally, when performing multi-step scanning as described above, the software limit (or software potential line) for one area or the CRT (Cathode
-ray tube). Then, the operator confirms whether or not the intended scanning range is met by checking the software limits displayed on the CRT.

<Problems to be Solved by the Invention> By the way, in the conventional technology, for example, only one region of the copying model 1 in FIG. Although it was possible to determine whether or not there was any overlap between each area of the entire model, it was not possible to check whether or not there was an unpatched part between each region.For example, if areas a to d do not overlap, unpatched parts will occur. , it was necessary to re-copy the remaining traces.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, it is an object of the present invention to provide a tracing control device that can easily and quickly check whether there is a portion left to be scanned.

Means for Solving the Problems〉 The configuration of the present invention that achieves the above object includes a tracing area storage unit that stores a plurality of tracing areas set on a model and with different tracing methods, and a scanning area storage unit that stores a plurality of tracing areas that are set on a model and have different tracing methods, and a plurality of tracing areas that display images. A copying area display setting section for selecting and specifying an area, and information on software limits and software potential lines indicating the copying area selected and specified by the copying area display setting section, sequentially retrieved from the copying area storage section, and the retrieved information a copying area display control unit that superimposes the image data and sends it out as image data, and a copying area display unit that receives the image data and displays software limits and software potential lines indicating one selected and designated copying area on an image display device in an overlapping manner. A tracing control device comprising:

By displaying multiple scanning areas simultaneously, you can not only judge whether each scanning area is appropriate, but also check whether there are any remaining areas on the entire model or avoid unnecessary scanning with many overlapping areas. It becomes possible to judge at once whether or not they have been carried out.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. Further, it is assumed that the model 1 shown in FIG. 2 is divided into areas shown in FIG. 3 and copied. Copying area shown in Figure 1
The t storage unit 11 stores a plurality of tracing areas a, b, c, and d set on the model 1. Each area a.

Patterns b, c, and d are copied using different methods.

The tracing area display setting unit 12 selects and specifies a plurality of areas for image display, for example, area a and area C. The scanning area display control section 13 displays the areas selected and designated by the scanning area display setting section 12, for example, areas a and c.

Information on software limits and software potential lines indicating the information is sequentially taken out from the copying area display section 11, and the copying area display section m section 13 superimposes screen information including the extracted information. As a result, the images showing the entire model 1 are overlapped at the same position to form one image, and the area a.

An image signal in which an image showing C is displayed simultaneously is created and sent out. The tracing area display unit 14 receives the image signal and displays the entire image of the model 1 and the software limits and software potential lines indicating areas a and C on the CRT 1.
Show on 5. This allows the software limits and software potential lines indicating regions a and C to be observed simultaneously with the image of model 1. Note that by specifying all areas a, b, c, and d in the scanning area display setting section 12, software limits and software potential lines indicating all areas "a, b, c, and d" can be displayed on the CRT 15.

<Effects of the Invention> As specifically explained above in conjunction with the embodiments, according to the present invention, it is possible to determine at once whether there is any remaining copying or extra copying between each area of multi-step copying, which saves time compared to conventional methods. The time it takes to set up tracing data can be reduced. In addition, in the past, if there was a trace remaining, it was often noticed after machining, and it was necessary to trace again, resulting in unnecessary trace machining.However, with the present invention, unnecessary trace machining can be prevented and the efficiency of mold machining can be improved. can be achieved.
