FIG. 5 shows details of the graphical dialogue module 40.

As shown, the graphical dialogue module 40 includes an MDI
It is comprised of a drawing signal manual section 40A that inputs operation signals such as 37, a machine allocation section 40B, a laser processing condition determination section 40C, and a processing condition display data creation section 40D. Machine allocation section 40B, laser processing condition determination section 40C1

The drawing signal input section 40A is an MDI illustrated in FIG.
37 operation signals are input, and for each unit element figure specified by the operator, it is sent to the processing condition display data creation section 40 via the machine allocation section 40B and the laser processing condition determination section 40C.
9D.

The MDI 37 shown in FIG. 6 includes a special key group 37A and a general-purpose key group 37 for easy operation, considering that this example is a multi-purpose processing machine 1 including a punch press machine and a laser processing machine.
It is composed of B.

The special key group 37A starts with a key for calling macro definition, and then moves (copy), calls product, calls nesting data, calls processing conditions, offset setting command, laser processing approach symbol, straight line, radius, etc. Specifying various shapes.

A-Z keys for specifying special processing, burring processing, etc.
It consists of an EOB key that indicates the end of input.

The general-purpose key group 37B is composed of a so-called numeric keypad and an edit key.

Therefore, according to the MDI 37 of this example, it is possible to easily manually manually machine the product figure to be machined by the multi-tasking machine 1 one by one using the special key group 37A on which appropriate pictograms are written and the general-purpose key group 37B. can.

The machine allocation section 40B automatically determines whether to perform punch processing or laser processing for the input figure based on the flowchart shown in FIG.

Shown in sequence, in step 701, the machine type parameters set for the machine are read, and if it is a laser-only machine, the process moves to step 702, where it is determined whether burring processing or special mold processing is included. However, if it is included, this machine cannot process it, so do not specify any processing. If it is not included, the process moves to step 703 and commands laser processing.

Here, since this example is a multi-processing machine consisting of a punch press machine and a laser processing machine, steps 701 to 704 are performed.
, the change mode is read, and if there is an overall change command to the laser, the process moves to step 702, but if not (partial change), the process moves to step 705.

In step 705, a hole shape is extracted from the figure.

Next, in step 706, it is determined whether or not the hole shape can be punched, and if punching is possible, step 70 is performed.
If not possible, the process moves to step 708. The determination here is that if the hole shape matches the pre-registered mold dimensions, it is determined that punching is possible; otherwise, it is determined that laser processing is possible.

Steps 707 and 708 are the processing range, that is, the work W
It is determined whether or not the hole position is within a range that can be punched due to the machine. If it is within the processing range, it is determined that punching is possible and the process moves to step 709. If not, the process moves to step 710 and laser processing is performed. Set.

In step 709, a mold request is further made, and in step 7
At step 11, it is confirmed that the mold can be set on the turret 7.8, and at step 712, punching is set.

In step 708, burring processing or special mold processing is determined in the same way as step 702, and if it is one of these special processings, no processing is specified, and if it is not one of these special processings, laser processing is specified in step 710.

The reason why punch processing was given priority in the above processing is that the speed of punch processing is superior to that of laser processing.

Therefore, in the process of this example, a figure can be automatically divided into three categories: punch processing, laser processing, or no designation. Further, the machining process designated in this manner can be changed by manual operation of the MDI 37.

In FIG. 5, the laser processing condition determination unit 40C:
For a designated figure to be laser processed, processing conditions such as laser processing speed are automatically determined based on FIGS. 8 to 10.

That is, the laser processing figure is input in step 801 of FIG. 8, and a straight line or a circular arc is determined in step 802. If it is a straight line, the process goes to step 803, and if it is a circular arc, the process goes to step 80
Move to 5.

In the case of a straight line, referring to the table data in FIG. 9, in step 803, predetermined processing conditions (H, M, L,
Ul to U7) will be set.

As shown in FIG. 10, the machining conditions include, in addition to the speed F, the laser output P, the laser frequency, and the duty R1 of the laser pulse.
The diameter of the tool (beam) is also determined, and each condition is expressed, for example, as a 1-word (8-bit) code, and the line segment data D includes (D, F, P, Q, R, D,
...) is added.

In step 804, the set conditions are stored together with the graphic data, and the colors are divided according to the speed conditions, and the colored display data is output to the CRTR 39.

A similar determination is made for circular arcs (step 805.
806).

The coloring conditions are determined, for example, as follows, taking into account the above-mentioned layout machine.

Punch processing...purple color laser processing (straight line H)...green (straight line M)...blue (straight line L)...yellow (straight line U)...light blue (arc L) . . Yellow and above. Specific operation examples of the graphical dialogue module 40 shown in FIGS. 5 to 10 are shown in FIGS. 11 to 13.

That is, when the MDI 37 is operated according to the procedure shown in the flowchart of FIG. 11, the screen of the CRT 30 is suitably transformed into a form that is easy to input, and the screen shown in FIG. By repeating the
As shown in FIG. 13, a desired machining shape can be input.

More specifically, on the screen shown in FIG. 12, graphical guidance 57 corresponding to the input content is displayed at the bottom right in a form that can be erased as appropriate by an expert, and above it are input items 58 such as starting point coordinates and ending point coordinates. It can be displayed as appropriate.

As shown in FIG. 14, in addition to being able to display dimensions, etc., the display figures are colored to allow identification of the allocation machine and laser processing conditions determined in FIGS. 7 and 8.

That is, in FIG. 14, the purple holes are shown to be punched, and the yellow, green, and blue holes are shown to be laser processed, and the speed of laser processing can also be determined by the color. It is possible.

In this example, the graphic data created in this way is transmitted to the graphic human power device (40) of the control device 13 attached to the multitasking machine 1.
The same applies even if the image is created using another graphic input device and sent using the IC card 53 as a medium.

Therefore, the NC program creation module 42 shown in FIG. 4 inputs the conditional graphic data shown in FIGS. 14 and 10, adapts the mold file 47 and the processing condition file 49 to this, and An NC program using the G code and M code shown in FIG. 16 is created and provided to the NC device.

The NC program shown in Fig. 16 indicates that, in the figure shown in Fig. 14, punching is performed using the mold T1, then piercing is performed at the starting end of the approach by laser processing, and then shape processing is performed in sequence. be.

To explain briefly, G92 indicates movement of the workpiece coordinates. G90 indicates linear movement and punching with the mold T1. The next Mloo indicates transition to laser mode. G62 indicates that the speed will be adjusted at the corners to prevent burns regarding the laser processing that will be performed from now on. G30 indicates that the beam diameter R-0°1 is given to the register of Pl. The next 090 indicates movement to the piercing position. GOO is the Z axis (
This indicates that the machining head) should be lowered. G32 shows the selection of assist gas type. G31 indicates piercing. G34 indicates the start of profile machining.

The next 600 indicates a temporary wait (dummy). 601 below indicates laser processing of the outer shape by linear movement. The next 63°3 indicates the end of contouring. G31 indicates that the laser output is stopped. GO
O indicates raising the Z axis. G40 indicates cancellation of beam diameter correction. Ml indicates laser mode cancellation. G50 indicates return to origin.

These G codes and M codes can be arbitrarily defined according to the machine manufacturer's convenience, and it is difficult for an experienced person to memorize them. It can be managed only with the drawings shown.
The effect is enormous.

In addition, in this example, the graphic data shown in FIG. 14 created in this way is stored in the IC card 53, so that it can be stored or provided to other machines of the same type or other models, and during this time, Graphical data stored in the IC card can be edited as appropriate, allowing for easy visual management.

In the multi-tasking machine 1 described above, the control device 13 has a configuration that integrates an automatic programming device 30 with a graphic input device (40) and an NC device 55, as shown in FIGS. 3 and 4. It has the following effects.

First of all, the automatic programming device 3 is connected to the NC device 55.
Since 0 is combined, when creating an NC program on site, there is no need to directly create the NC program shown in FIG. 16, and it is sufficient to input the machining figure shown in FIG. 14. In other words, since there are generally no G-code and M-code experts on-site, on-site workers can perform NC
This is important for creating programs in a timely manner.

Second, as shown in FIG. 4, since the processed data managed by the automatic programming device 30 is made into graphic data, the processed data can be managed in visually visible figures, making it extremely easy to manage and invisible to the untrained eye. This also makes it easier to understand and eliminates the possibility of mistaking the processed data for something else.

Also, in this case, since the graphic data is interposed between the IC card 53 and the external device, the management of the IC card, and even the host computer, can be managed using the graphic data, and the entire factory can be managed. This makes management easier.

Thirdly, since the graphic interaction module 40 shown in FIG. 4 is configured as shown in FIG. 5, it is easy to use human power, and it is possible to add processing conditions to graphic data and manage it as shown in FIG. It is intuitive and can prevent processing errors.

In the above embodiment, the processing machine is an example of a punch and laser processing multi-purpose processing machine 1, but it goes without saying that the present invention can be applied to various machines such as a single machine or a machine configured as a system. Furthermore, graphic data used in one machine can be used in other machines as well.

Further, in the above embodiment, although the graphic human input device (40) is used as an example, the NC program inputted from the NC tape 54 in FIG. 4 is converted into graphic data by the conversion module 41, and the product data file 44 The figures stored in the memory card 53 and the figure data input from the IC card 53 are transferred to the C again.
The scope of application is various, such as checking or editing on the RT39 screen and processing with transformed graphic data.

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

[Effects of the Invention] As described above, since the present invention is a method for controlling a processing machine using an IC card as described in the claims, processing data can be managed in the form of graphics, and this graphic data can be transferred to the IC card. Since a card is used as a medium to intervene in the system, and each processing machine automatically generates its own NC program, processing data is extremely easy to manage and machine control is facilitated.
