Abstract

PURPOSE:To preclude repetitive working, an omission of working, or a relative position shift by displaying pieces of plotting information on different machining shapes on the same screen, and generating NC data corresponding to the different piece of plotting information and outputting them individually to a storage medium. CONSTITUTION:An NC data generating means 2a displays the pieces of plotting information on the different machining shapes inputted from a keyboard 3 or mouse 4 as an input means on the same screen of a CRT 1, generates the NC data corresponding to the pieces of plotting information on the different machining shapes, and outputs the generated different NC data to a tape puncher 5 individually. Consequently, this constitution generates the NC data which causes none of the repetitive working, omission of working, and relative position shift even when working is carried out by plural working machines.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a CAD-CAM device for generating processing NC data to be supplied to, for example, a two-dimensional processing laser processing machine and a turret I topanse. .

[Conventional technology]

FIG. 4 shows the hardware configuration of a CAD-CAM device for two-dimensional processing, for example. In the figure, (1) is a CRT
, (2) is the arithmetic unit, (3) is the keyboard, (4)
(5) is a tape punch J-1 that outputs N(, -'-), (6) is a paper tape as an output medium for the processor. There is.

Next, a conventional method for creating two-dimensional NC data will be explained. When creating NC data based on each machining shape diagram shown in Fig. 6, C! IILT (1) While looking at the screen, input points and lines of one circle that constitute the processing shape using the keypad threshold (3) and the mouse (4). The procedure is to first select the origin person camo-V, specify an arbitrary position on the CRT (1) screen with the mouse (4), and set it as the origin (coordinates x
@, '(@). Next, to input the machining start point, select the 1-point large camo, and enter the coordinate values (for example, X-5, YUJl) from the keyboard
Enter the four circles (corner 8). After inputting the graphical elements constituting the machining shape, the order of the machining path is specified by dragging the mouse a. Thereafter, an NC data creation process is performed to convert the input data created by the input operation into NC data, and then processed data is outputted using a tape punch (5) or the like. This move) @ is shown in Figure 5.

(Problem to be Solved by the Invention) Since the conventional CAD-CAM device ill is configured as described above, for example, when processing a part of the same part with a tally topane mill after laser processing, a separate tally-top bunch is used. It is necessary to draw only the machining parts for sag, tachi, etc. using the Φ software, specify the machining, and output NO data for sag, tachi, etc. Duplicate machining, machining omissions, or relative position deviations may occur. T-co has a problem to solve.

This invention was made in order to solve the above-mentioned problems, and generates NC data that does not cause duplicate machining, machining omissions, or relative positional deviations even when multiple machining is performed using multiple machining machines. The purpose is to obtain a CAD/CAM system that can be used.

[Means to solve the problem]

The CAD-CAM device according to the present invention includes a display means for displaying a drawing state of a processed shape, an input means for inputting drawing information of the processed shape, and a display means for inputting different drawing information inputted from the input means. The apparatus is equipped with an NC data generating means that generates one piece of NC data corresponding to the machining shape while displaying it on the same screen, and outputs each of the generated different NC data individually to an NC data storage medium. be.

[Effect]

In this invention, the NC data generation means displays drawing information of different machining shapes input from the input means on the same screen of the display means, and generates NC data corresponding to the different drawing information and individually stores the drawing information on the storage medium. Output to.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, the same reference numerals as in FIG. 4 showing the conventional example indicate the same parts, so the explanation thereof will be omitted. In the figure, (2a) is the keyboard (3) which is the input means.
, controls the screen display of ll0RT (1) by input commands from the mouse (4), and N.

It is an NC data generation means that generates data and outputs the result to the tape punch J+ (5). Also, Figure 2 shows N
A flowchart showing the procedure for generating C data, FIG.
It is a figure which shows an example of the drawing state of the process shape displayed on RT(1) screen.

Next, the operation will be explained. For example, the machining shape shown in Fig. 3 is created using the CAD function on the step 1 shown in Fig. 2. Select it and enter the laser processing start point (e) using the mouse.

Next, as shown in the stage (82b), select the machining section for sauce and topanse with the mouse in the same way, and select the tool to be used for machining (round tool or square tool, its size, etc.) .After that, specify the NC data creation process,
Step 88A (88B) Create NC data for the laser and for the tray 1 punch as shown in the following steps.

Finally, the steps .

In addition, the method of specifying the machining part and the creation and output processing of each NC data are the same as those conventionally performed for convergent surfaces.In the above embodiment, two-dimensional NC data is used for laser and It can also be used for turrets and topances, marquees and nogs, and for waste cards and electrical discharge machines. It goes without saying that it is possible not only to use two processing machines, but also to add processing for each processing machine. [Effects of the Invention] As described above, this invention allows While drawing a plurality of different machining shapes on the same screen of the display means by the data generation means, it is possible to correspond to each of the different machining shapes.
=Constructed so that NC data is generated and stored individually in a storage medium (γ) This has the effect of obtaining flatness accuracy that does not cause duplicate machining, machining omissions, or relative positional deviations.
