Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an automatic programming device for laser-punch complex processing.

(Prior Art) In recent years, combined laser/punch processing, which combines laser processing and punch processing, has been performed on one workpiece. This is because when arranging various machining shapes on one workpiece, one shape may be laser or punch machined depending on the machining shape or specified due to the molds held or due to machining accuracy issues. It is something.

As the processing machine, a laser processing machine and a punch processing machine arranged in parallel or in series, or a combined laser/punch processing machine can be used.

Conventionally, when processing a center punch with a laser in such laser-punch combined processing, processing conditions were set manually.

In other words, a center punch can be punched using a center punch tool, or it can be used as a center punch by, for example, cutting cross-shaped lines with a laser. With a center punch, it is necessary to set many processing conditions such as the shape of the scribing line, scribing speed, laser output (power, pulse frequency, duty ratio), and assist gas, and these conditions must be set manually. was.

Therefore, with conventional automatic programming devices for laser/punch combined processing, although it is possible to display the center punch position on the processing figure and express that center punch processing should be performed, laser processing It is not possible to specify whether it is by laser processing or by punch processing, but if the center punch is by laser processing, it must be laser processing.
The processing conditions were individually set manually.

(Problems to be Solved by the Invention) However, as mentioned above, in the conventional automatic programming device for laser punch combined processing,
Since the method involved manually specifying the center punch by laser processing, it took a lot of time to specify it, and it took a lot of effort and time to create the NC program.

Therefore, the present invention provides the following features in laser punch composite processing:
To provide an automatic programming device in which a laser center punch can be specified on a figure in the same way as a punch processing center punch, and there is no need to individually set processing conditions for the laser center punch.

[Structure of the Invention] (Means for Solving the Problems) The present invention that solves the above problems is an automatic method for creating NC programs for laser processing and punch processing for a workpiece that is subjected to combined processing of laser processing and punch processing. The programming device includes a laser/punch figure data input section for inputting figure data indicating the shape of a workpiece for laser and punch processing, a center punch mark by laser processing shown on the figure data, and a center punch mark by laser processing shown on the figure data. Laser processing is performed by comparing the center punch identification mark storage unit that stores the identification mark of the center punch mark, and the figure input and set in the figure data input unit with the identification mark stored in the center punch identification mark storage unit. a center punch determination unit that determines a position to be center punched by a laser or a punch process, and a center punch determination unit that determines a position to be center punched by a punch process; a mark-corresponding machining condition storage unit that stores machining conditions for the mark; and a center punch by laser or punch processing at the position determined by the center punch determination unit, with reference to the machining conditions stored in the mark-corresponding machining condition storage unit. A mark-compatible NC program creation section that creates an NC program for machining, and an N created by the NC program creation section.
Features (Functions) The automatic for laser/punch combined processing of the present invention is characterized by being equipped with an NC program output unit that outputs a C program to a laser processing machine, a punch processing machine, or a laser/punch combined processing machine. The programming device has a center punch mark created by laser processing,
The center punch mark produced by punch processing is expressed separately, for example, by dividing it into a circle indicating the center point and a cross shape, and the processing conditions corresponding to each mark are memorized and shown on the figure. The mark on the center punch is identified and an NC program is created according to predetermined machining conditions.

Therefore, the programmer places a center punch on the shape,
By simply specifying whether laser processing or punch processing is to be used by attaching an identification mark, an NC program for the center punch can be automatically created. The laser processing conditions may be input and specified in advance. It is also possible to specify multiple machining conditions, such as whether to use only scribe lines or whether to provide a pinhole in the center, and select and set them according to the workpiece.

(Embodiment) Referring to FIG. 1, a laser beam according to an embodiment of the present invention is shown.
The punch composite processing automatic programming device 1 includes a laser punch figure data input section 2 for inputting figure data for performing laser punch processing.

The graphic data input unit 2 may be an image scanner device that directly inputs drawings, or may input and store graphic data created by CAD.

In the drawing or graphic data input here, the shape to be processed by laser processing or punch processing is shown, and the center punch position for laser processing or punch processing is written using an identification mark of the processing type. The identification mark will be explained in detail in FIG.

A center punch determining section 3 is connected to the laser punch figure data input section 2 . A center punch identification mark storage unit 4 is connected to the center punch identification unit 3 .

The center punch identification mark storage unit 4 stores reference figures for pattern recognition of circles and cross marks having a center point as shown in FIG. A circle with a center point indicates a punch center punch, and a cross mark indicates a laser center punch.When punching, punching must be performed using a punch tool at the center of the mark. is stipulated. Furthermore, it is stipulated that a center punch mark formed by laser processing is to be laser processed using a preset processing condition At around the center of the mark.

FIG. 4 is an explanatory diagram showing types of processing conditions for laser processing.

In the figure, condition A1 is to maximize the laser output (power) at the center position to mark a cross shape with a laser;
By heating the center position more greatly, the center point of the cross mark can be printed more easily.

Condition A2 is such that a pinhole is made at the center of the cross shape, and then the cross line is marked with a laser.

Condition A3 is such that after making a pinhole, a circle is marked on the outside with a laser.

These conditions may be selected in advance depending on the workpiece.

Referring again to FIG. 11, the center punch discrimination section 3 refers to the center punch identification mark storage section 4 and discriminates the processing type of the center punch by pattern identification.

A mark compatible program creation unit 5 is connected to the center punch determining unit 3, and a mark compatible machining condition storage unit 6 is also connected to this. Mark-compatible machining condition storage unit 6
In addition to storing the laser processing conditions shown in FIG. 4 in association with each mark, the processing conditions for punch processing are also stored.

In this example, only the selected condition among the plurality of machining conditions At shown in FIG.
is read out.

Therefore, the mark-compatible NC program creating section 5 can set the processing conditions for laser or punch processing according to the marks on the figure, and create the NC program.

To give an example of an NC program, first, in the case of a punch press, the program is programmed to punch the shape using the punch press, then index the tool for the center punch, and use this tool to sequentially process all the center punch parts. Ru. Regarding center punches made by laser processing,
Since there is no need to change tools, there is no need to put all the center punch parts together; for example, before and after cutting one shape, a center punch is machined on the center punch part shown in that shape, and the next shape is cut. Programmed to move to machining.

The combined form of the laser and punch is the same whether it is a combination of a laser processing machine and a punch press machine on a line or a multifunction processing machine that integrates both.

An NC program output section 7 is connected to the mark-compatible NC program creation section 5, and the created NC program is output to a predetermined machine online or offline.

The above center punch program creation procedure is summarized in Fig. 2. In step 201, CAD data is input, and in step 20
In step 203, the center punch mark is extracted, and in step 203, the processing machine is determined.

In case of center punch processing by laser processing,
The process moves to step 204, where a center punch laser program is created.

If center punch processing is performed by punch processing, the process moves to step 205, where a center punch punch program is created.

As described above, in the automatic programming device for laser/punch combined processing of this example, it is possible to create an NC program by indicating the center punches for laser processing and punch processing with different marks on the figure and having them automatically discriminated. .

Furthermore, since a plurality of machining conditions are set in advance and selected and set according to the workpiece, it is possible to form an optimal center punch according to the material of the workpiece or the use of the workpiece.

In the above embodiment, for laser processing, the processing conditions shown in Fig. 4 are selected and specified, but the marks of the plurality of laser punches shown in Fig. 4 are shown on the figure so that they can be identified including the processing conditions. It's okay.
