Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program conversion device for a laser / punch compound machine for converting a partially omitted machining program for controlling the laser / punch compound machine to a completed state.

[0002]

2. Description of the Related Art As a laser / punch composite machine, there is a composite machine equipped with a turret type punch mechanism section 50 and a laser head 55 as shown in FIG. The punch driving unit 50 installs a punch tool 53 and a die tool 54 at respective tool stations arranged on the outer peripheral portions of the upper and lower turrets 51 and 52, and slides the punch tool 53 at a punch position P (not shown). ) To drive up and down. The work feeding device 62 feeds the plate-shaped work W placed on the table 56 back and forth (Y axis direction) and left and right (X axis direction) by the work holder 57. Work holder 5
The carriage 7 is driven back and forth together with the carriage 58 by a Y-axis servo motor 59 and a feed screw 60, and is driven left and right by an X-axis servo motor 61 and a feed screw (not shown).

In an NC device controlling such a laser / punch composite machine, when processing an offset between a punch center P and a laser center R, a T code (tool command code) for laser processing is used to offset the offset. I'm hanging.

An example of the machining program is shown in FIG. In the figure, the machining program 63 is described in NC code, and one block is shown in one line. The blocks B1 to B7 are sequentially executed. Blocks B1 and B2 in the first two rows are commands for punching, and a tool command code "T1" for indexing a predetermined punch tool 53 in the turrets 51 and 52 and a feed command for moving the plate material W in the X and Y directions. It consists of codes "X ..." And "Y ...".

A block B3 on the third line is a laser processing mode command "M20" indicated by an M code (preparation code).
And a T code “T92” for offsetting. When the laser processing command “M20” is issued, the laser / punch multifunction machine is in the laser processing mode until the next laser processing end command “M24” shown in block B6. Further, the "T92" code causes the work feeding device 62 to shift the origin of the work coordinates by the distance L between the punch center P and the laser center R. That is, offset processing is performed. Blocks B4 and B5 are commands for feeding the work. A block B7 is a command for punching, and like the blocks B1 and B2, is composed of a tool command code "T1" and feed command codes "X ...", "Y ...".

[0006]

When forming the machining program 63, when switching to the laser machining mode,
There is a case where only the laser processing mode command “M20” is described and the description of the T code “T92” for offset is forgotten. Therefore, processing may be performed without performing offset processing, resulting in a defective product.

An object of the present invention is to provide a program for a laser / punch multi-function machine which can perform an excellent operation of the multi-function machine by performing offset processing without writing a tool offset command when switching to the laser processing mode. It is to provide a conversion device.

[0008]

The structure of the present invention will be described with reference to FIG. 1 corresponding to an embodiment. The program conversion device (1) of the laser / punch compound machine reads the machining program (9), recognizes the laser machining mode command (11) in the machining program (9), and recognizes the laser machining mode command (11). Further, an offset command generating means (7) for adding a predetermined tool offset command (12) is provided.

[0009]

Each command in the machining program (9) before conversion is sequentially read by the offset command generating means (7), and if there is a laser machining mode command (11), that command (1
The tool offset command (12) is added to 1).

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. This program conversion device 1 will be described later in FIG.
The conversion program described below and a computer that executes the conversion program are provided as a part of the automatic programming means 3 in the programmable machine controller 2 as shown in FIG. 3, or as shown in FIG. It is separately provided in the programmable machine controller 2.

The programmable machine controller 2 is
It controls the entire complex machine shown in FIG. 5 together with the NC device 4, and has a sequence control function and a man-machine interface function. The NC device 4 is a means for executing a machining program generated by the automatic programming means 3 or the like to give an axis feed command to the servo controller 5 and transferring a sequence control code in the machining program to the programmable machine controller 2. The NC device 4 includes an offset correction unit 6 that performs an offset of the axis feed command in response to the tool offset command in the machining program. In the case of the configuration of FIG.
In the process of executing the machining program created by the automatic programming means 3 in the NC device 4, the machining program is transferred to the program conversion device 1 and the converted machining program controls the multifunction machine.

In FIG. 1, the program conversion device 1 comprises an offset command generating means 7 and a T code generating means 8. The offset command generating means 7 is a means for reading the machining program 9 before conversion, recognizing the laser machining mode command 11, and adding a predetermined tool offset command 12 to this command 11. The T code generating means 8 reads the processing program 9 and recognizes the laser processing mode end command 13, and then, in the next block A7, the laser processing mode command 1
This is means for adding the tool command code 14 of "T1" in the block A3 immediately before 1.

The machining program 9 is divided into blocks by NC code, and the tool offset command is omitted in the same block A3 in which the laser machining mode command 11 is described before conversion. In the block A7 next to the laser processing end mode command 13,
The T code for selecting the punch tool is omitted.

FIG. 2 shows the program conversion operation according to the above configuration.
Will be explained together. The machining program 9 before conversion is sequentially read into the program conversion device 1 for each block (S
1) If either the laser processing mode command 11 or the laser processing mode end command 13 is not recognized, the next block is read without performing any processing through steps S2 to S5. Therefore, the blocks A1 and A2 are directly output as the post-conversion machining program 10 without any processing.

When the laser machining mode command 11 indicated by "M20" in the block A3 is recognized, the process proceeds from step S2 to step S3, and the converted machining program 10 has the laser machining mode command 11 in block A3 '.
To the tool offset command 12 indicated by "T92". Also, the T of "T1" in the immediately preceding block A2
The code 14 is stored in a predetermined storage area (S4), and the next block A4 is read (S1).

When the laser processing mode end command 13 indicated by "M24" in the block A6 is recognized (S5), it is checked whether or not the T code is specified in the next block A7 (S6), and there is no specification. In this case, the T code 14 consisting of "T1" immediately before laser processing stored in step S4
Is added to the beginning of the next block A7. Next block A7
If the T code is designated in advance, the process proceeds from step S6 to S1 to read the next block (not shown) without performing any processing.

According to the program conversion device 1, the laser processing mode command 11 and the laser processing mode end command 1 which are always necessary in the pre-conversion processing program 9 are thus made.
A tool offset command 12 consisting of a T code and a T code 11 immediately before laser processing can be internally generated only by inputting 3. Therefore, the work of inputting these T-codes 11 and 12 is not required, the input work for creating the program is facilitated, and forgetting to insert the T-codes 11 and 12 is prevented.

The T code 14 added to the block A7 of the laser processing mode end command 11 is the T code immediately before the laser processing.
It is a code, but in this type of multi-function machine, the same punch tool is often used before and after laser processing. Conventionally, the T code is left in the block A7 when the punch tool is not changed. If the punch tool is not changed, the T code is hardly left in the block A7. Therefore, an efficient machining program can be created by always adding the immediately preceding T code 14. If it is necessary to change the punch tool, a T code may be described in advance in the block A7 following the laser processing mode end command 13.

[0019]

As described above, the program conversion device for a laser / punch compound machine according to the present invention is provided with the offset command generating means for reading the machining program to recognize the laser machining mode command and adding a predetermined tool offset command to the command. The tool offset command can be automatically generated and the multifunction peripheral can be operated well without inputting the tool offset command when switching to the laser processing mode. Therefore, the input operation for creating the machining program is easy, and the malfunction due to an input error can be prevented.
