Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for a laser / punch compound machine which performs numerical control.

[0002]

2. Description of the Related Art In a laser / punch compound machine, laser processing is selected for fine processing that cannot be punched and for cutting that is inefficient in punching. Many processed shapes can be processed by both laser and punch, but in the case of such processed shapes, punching is generally selected from the viewpoint of running cost. On the other hand, since punching produces a large amount of noise, it may not be possible to operate at night depending on the surrounding environment of the factory. In such a case, in order to operate at night, laser processing is required even if the running cost is high.

Conventionally, when punching and laser machining having the same shape are performed, a punching machining program and a laser machining machining program are separately prepared. Therefore, there is a problem that it takes time and effort to create the machining program and the memory capacity required for storing the machining program becomes large.

An object of the present invention is to control a laser / punch compound machine in which punching can be switched during the daytime and laser processing can be performed during the nighttime without special preparation of a laser machining program, and the memory capacity can be small. It is to provide a device.

The structure of the present invention will be described with reference to FIG. 1 corresponding to an embodiment. This controller (10)
In a control device (10) equipped with a machining program executing means (15) for causing a laser / punch compound machine to execute a punching program and a laser machining program, a machining program converting means (16) and a day / night switching means (1).
7) is provided. Machining program conversion means (1
6) converts the punching program (14) or the punching graphic data into a laser machining command in the course of execution by the machining program executing means (15).
The day / night switching means (17) is a processing program conversion means (1
6) is operated at a predetermined night time.

[0006]

According to the controller (10), the punching program (14) is prepared so that the punching is performed by the laser / punch compound machine in the daytime and the punching program (14) or the punching program (14) at night. The pattern data for punching is converted into a laser processing command by the processing program conversion means (16) and laser processing is performed. Therefore, punching is performed in the daytime and laser processing is performed in the same shape at night without preparing a laser processing program. Since the laser processing command is sequentially converted from the punching program (14) or the punching graphic data in the course of execution by the processing program executing means (15), a memory area for storing the laser processing program is unnecessary. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. A laser / punch multifunction machine 1 to which this control device is applied is one in which a laser head R is provided in front of a punch head P on a frame 3 of a turret punch press machine having a turret 2. A crank or hydraulic punch drive mechanism (not shown) is installed on the frame 3, and a laser oscillator (not shown) is installed adjacent to the frame 3. The plate material feeding device 4 has a cross slide 6 that moves left and right (X axis direction) on a carriage 5 that moves back and forth (Y axis direction), and a plate material W is gripped by a work holder 7 attached to the cross slide 6. Then, the work table 8 is moved back and forth and left and right.

The control device comprises an NC device 10 having a numerical control function part and a programmable controller function part. The NC device 10 is provided with a machining program executing means 15 for executing a punching program and a laser machining program including NC codes and giving a control command to the laser / punch multifunction machine 1, and a machining program memory 13. A machining program conversion means 16 and a day / night switching means 17 described later are provided.

An automatic programming device 12 for automatically generating a punching machining program from the machining figure data of the CAD data file 11 is provided along with the NC device 10, and the punching program 14 thus generated is stored in the machining program memory. 13 is stored.

The punching program 14 is composed of a sequence of commands composed of blocks. In the command block, in addition to the block of commands for one punch, a predetermined shape pattern is machined by a large number of punching operations. Various pattern function command blocks 14a to be executed are included.

For example, when punching a workpiece W shown in FIG. 2A with an outer peripheral shape k, punching for cutting one side k1 is performed by using a tool T indicated by a hatched area as shown in FIG. 2B. It is performed by using a plurality of punch operations while shifting the punch position in the X-axis direction at a constant pitch d.
Such processing is given by, for example, the pattern function command 14a "INK / adn". This command is to punch on the straight line parallel to the X-axis or the Y-axis, starting from the current tool position (or another commanded position), in the direction a and n times with the pitch dmm. ", Followed by an adn alphabetic character.

The pattern function command execution means 19 in the machining program execution means 15 is means for decoding such a pattern function command 14a and giving a punching command for each time. A large number of types of pattern function commands 14a that can be read by the pattern function command executing means 19 are prepared, and the automatic programming device 12 does not use one punch block within a possible range, and the pattern function command 1
It is assumed that the machining program 14 is created using 4a.

Machining program conversion means 1 of NC device 10
Reference numeral 6 is a means for converting each command of the punching program 14 in the machining program memory 13 into a laser machining command that can be read by the machining program executing means 15. The converted laser processing command is output to the processing program executing means 15. That is, while causing the machining program executing means 15 to execute the converted laser machining command, the commands of each block of the punching program 14 are sequentially converted into laser machining commands. The conversion operation may be performed while pre-reading the punching program 14 little by little.

The machining program converting means 16 includes a pattern function command block 14a of the punch machining program 14.
Is provided with a pattern function command conversion means 18 for directly converting into a predetermined laser processing command. For a normal punch command, for example, data of the tool shape corresponding to the tool number is obtained from a predetermined file (not shown), and a command for laser machining the shape of each tool is given. .

The machining program converting means 16 uses C
The laser machining command may be created from the AD data file 11 or the machining figure data in the process of creating the punching program 14 by the automatic programming device 12, or both such machining figure data and the punching program 14 may be created. The laser processing command may be created from the data of.

The day / night switching means 17 is a means for operating the machining program converting means 16 only during an arbitrarily set night time and causing the machining program executing means 15 to execute the storage program of the machining program memory 13 at other times.

The control operation of the above configuration will be described. In the daytime,
The punching program 14 stored in the machining program memory 13 is executed by the machining program executing means 15,
Punching is performed by the laser punch composite machine 1.

At the night time set in the day / night switching means 17, the punching program 14 in the machining program memory 13 is converted into a laser machining command by the machining program converting means 16, and then the machining program executing means 15 is executed.
The laser / punch compound machine 1 performs the laser processing performed by the laser punching machine 1 to obtain a product having the same shape as the punching. Therefore, punching can be switched during the day and laser processing can be switched during the night without preparing a program for laser processing. Further, a memory area for storing the laser processing program is unnecessary, and the capacity of the processing program memory 13 can be small.

Further, in this embodiment, many commands of the punching program 14 are set to the pattern function command block 14
Since it is configured by a and is directly converted into the laser processing command, it is possible to perform the laser processing only on the shape required for the product, instead of directly performing the laser processing on the shape of the punch tool.
For example, in the example of FIG. 2B, only the cutting process of the side k1 is performed, and the process of cutting the outer shape of the punch tool T in each punching process is not performed. Therefore, efficient laser processing can be performed without wasteful processing.
