Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a processing figure input device used in the field of metal processing.

(Prior Art) In recent years, automatic programming devices have come into use in the field of metal processing such as sheet metal processing. The automatic programming device automatically creates an NC program for the operation of the processing machine by matching processing machine conditions to processing figures automatically input by a scanner device or the like or manually input figure data.

Therefore, conventionally, various graphic input devices have been proposed in order to create machining figures that are input directly or indirectly to this automatic programming device.

Since general-purpose CAD is not intended only for the metal processing field, there is a problem in that it is difficult to input information.

Furthermore, since the machining figures are submitted to the automatic programming device and are intended for creating NC programs for the machining machine, there is a problem in that the machining figures completed in general-purpose CAD cannot be directly provided to the automatic programming device. There is a point.

In other words, it is necessary to add machining conditions to the machining figure rather than just the product shape, but for machining figures created with general-purpose CAD, new machining conditions are detected and then provided to the automatic programming device. This requires a large amount of input man-hours.

Furthermore, when the machining figure and the machining conditions are defined separately, there is a problem that it is not possible to estimate the machining state using only the completed machining figure, and sufficient figure management is not possible.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a graphic input device that allows easy input operations, reflects machining conditions, and can create graphics that are easy to manage.

and processing condition display data creation means C4 for causing the display means C3 to display conditioned figures, such as coloring, by associating each line segment of the drawn figure with a processing condition set automatically or by means. Features.

(Function) The graphic input device of the present invention is provided with a guidance storage means C2, and displays guidance in a form that can be erased as appropriate depending on drawing conditions.

Further, a machining condition display data creation means C4 is provided, and each line segment of the drawn figure is given a color determined for each machining condition, for example, and displayed on the display means C3. It does not have to be a color, but may be a coded symbol.

Therefore, with the graphic input device of the present invention, it is possible to perform an input operation while arbitrarily displaying guidance appropriately defined according to the processing object according to the skill level of the inputter, and furthermore, it is possible to perform an input operation while displaying guidance appropriately defined according to the processing object, and also to perform input operations while displaying guidance appropriately defined according to the processing object. For example, since it is displayed in color, the processing state can also be estimated from the displayed figure. Furthermore, since machining conditions are attached to the completed figure, it can be provided as is to an automatic programming device, making it extremely easy to manage machining data.

As shown, the graphic interaction input module 40 includes MD1
It is composed of a drawing signal input 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 40B1 Laser processing condition control section 40C1
The processing condition display data creation unit 40D generates the above various files F' (43, 44, 45.46.50.51.52)
You can refer to the contents as appropriate. The display data creation section 40D with processing conditions is connected to the color CRT 39 and the product data file 44.

The drawing signal input section 40A is an MDI illustrated in FIG.
37 to 4o operation signals are input and provided to the processing condition display data creation section 409D via the machine allocation section 40B and the laser processing condition determination section 40C for each unit element or element figure specified by the operator. It is something.

The MDl 37 shown in FIG. 6 has 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 includes movement (copying), product calling, nesting data calling, processing condition calling, offset setting command, laser processing approach symbol, straight line, radius, and others. Specifying various shapes. Special processing. It consists of A-Z keys for specifying burring processing, etc., and an EOB key for indicating 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 input product figures to be processed by the multi-tasking machine 1 one after another 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, as in step 702, burring processing or special mold processing is determined, and if these special processings are used, no processing type 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 type 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, predetermined machining conditions (H, M, L,
Ul to U7) will be set.

As shown in FIG. 10, the machining conditions are determined in addition to the speed F, laser output P, laser frequency Q, laser pulse duty R1, tool (beam) diameter D, and for each condition, for example, one word (8 bits) is determined. ), and the line segment data DI: (D, F, P, Q,
R, D...) are 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 graphic interaction input 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 39 is transformed into a large shape with appropriate input, and the screen shown in FIG. As shown in FIG. 13, the desired machining shape can be input by overlapping the .

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 is now possible to display it 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.

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 M100 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 P1. The next 090 indicates movement to the piercing position. GOO indicates lowering the two axes (processing head). G32 shows the selection of assist gas type. G31 indicates piercing. G34 indicates the start of profile machining.

The next 000 indicates a temporary wait (dummy). The GOI below indicates that the outer shape is laser-processed by linear movement. The next 033 indicates the end of profile machining. G31 indicates that the laser output is stopped. G00

These G codes and M codes are codes that 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 in the diagrams, and the effect is enormous.

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

Since code experts are not assigned, N
This is important for creating C programs in a timely manner.

jl2, as shown in FIG. 4, the processing data managed by the automatic programming device 30 is set as graphic data, so
The processed data can be managed in visually visible figures, making management extremely easy and easy to understand even for an untrained eye, and there is no 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.

Furthermore, although the above embodiment has been shown as an example in which figures are input from the figure input device (40), the NC program inputted from the NC tape 54 in FIG. The figures stored in the CRT and the figure data input from the IC card 53 are transferred to the CRT again.
The scope of application is various, such as checking or editing on the 39 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.

〔Effect of the invention〕
