Description

Detailed Description of the Invention 3. Detailed Description of the Invention (a) Industrial Application The present invention provides operation control of a laser processing machine that uses a processing program for a turret punch press to control the operation of a laser processing machine. Regarding the method.

(b), Prior Art Usually, when processing sheet metal, a turret punch press or a laser processing machine is often used, and the processing contents of both are often similar.

Therefore, the workpieces that can be processed with a turret punch press are:
In many cases, it can also be processed using a laser processing machine.

(C)0 Problems to be solved by the invention Sheet metal processing using a turret punch press can punch out a predetermined area with a single punching operation, so the processing speed is fast, but it is necessary to create a mold. Therefore, it is not suitable for low-volume, high-mix production.

In addition, processing using a laser processing machine does not require the effort of creating a mold as all the processing shapes can be created using the processing program, and is highly effective for special shapes, etc. However, the processing speed etc. are slower than the punch press. It is slower than conventional methods, and has the disadvantage of deteriorating processing efficiency in high-volume, low-variety production.

On the other hand, the processing method using a turret punch press has been largely established due to the long history of punch press machines, and there is a large accumulation of processing programs for turret punch presses at processing sites such as factories. . Second, laser processing machines have a short history of use in sheet metal processing, and there are few processing programs accumulated.
In prototyping, etc., it is often more advantageous in terms of man-hours and costs to process with a laser processing machine than to go to the trouble of creating a mold for a turret punch press.

However, when operating a laser processing machine, as described above, it is necessary to specify all the processing shapes in a processing program, which is naturally different from the procedure for creating a processing program for a turret punch press.

Therefore, the operator ζ of the turret punch press cannot make use of the knowledge of the machining program related to the turret punch press, and is required to acquire new knowledge of the machining program related to the laser processing machine. Therefore, either it takes a lot of time to create a new machining program, or the vast amount of machining program assets related to the turret punch press are wasted.

In order to eliminate the above-mentioned drawbacks, the present invention enables the assets of a processing program related to a turret punch press to be effectively utilized for processing with a laser processing machine, and moreover, allows an operator who is skilled in creating a processing program for a turret punch press. but,
It is an object of the present invention to provide an operation control method for a laser processing machine that allows the laser processing machine to be operated in the same manner as a turret punch press.

(d) Means for solving the zero problem, that is, the present invention converts a cannibal gastrogram (PPR) created for a turret punch press into a processing program (PRO) for a laser processing machine, and The laser processing machine is configured to operate and control the laser processing machine based on the converted processing program.

Note that the numbers in parentheses are for convenience and indicate corresponding elements in the drawings, and therefore, this description is not limited to the descriptions on the drawings. r (a) below
The same applies to the column ``, action''.

(e) 0 effect With the above-described configuration, the present invention converts a processing program (PPR) of a turret punch press into a form that can be executed by a laser processing machine, and the converted processing program (PPR)
The operation of the laser processing machine is controlled based on the RO.

As shown in FIG. 1, the laser processing machine 1 has a main control section 2, and a display 5, a keyboard 6, and each axis of the laser processing machine 1 are connected to the main control section 2 via a path line 3.

Since the laser processing machine 1 has the above configuration, when processing with the laser processing machine, the operator inputs processing commands for a predetermined shape using the turret punch press using the keyboard 6.

Note that G69 and G79 are distinguished from each other due to differences in punch operation control, and the shapes to be cut and processed are the same.

When the operator inputs the machining data DAT of the turret punch press in the form of a G code from the keyboard 6, the machining data DAT is stored in the punch press program memory 10 as a machining program PPR. Since this machining program PPR can only be used for turret punch press machining as it is, the main control unit 2 confirms that the input of machining data DAT by the operator has been completed and the creation of the turret punch press machining program PPR has been completed. At this point, the program conversion calculation section 12 is instructed to convert the Niprogram program PPR into a form that can be executed by a laser processing machine.

When the program conversion calculation unit 12 receives a command to convert the machining program PPR from the main control unit 2, it first reads out the created machining program PPR for the turret punch press one block at a time from the punch press program memory 10, and The block is finally converted into a form executable by a laser beam machine, and more specifically, a machining path of the laser beam machine is calculated and generated from the machining program PPR, and the generated machining path is stored in the conversion program memory 13. The movement command MCD indicating the movement command MCD is sequentially stored.

That is, the read block is, for example, G shown in FIG.
In the case of the oo (single punch) command, the program conversion calculation unit 12 reads from the system program memory 11,
Read subroutine 5UBI. Subroutine 5UB
1 is a program that converts the 000 command into a movement command for the laser processing machine, as shown in FIG. 21. In step S1, first, the punch position (
A fast-forwarding command to a laser processing start position (a position where viasing is performed) corresponding to x, y) is generated.

Since the piercing position differs depending on the tool, the program conversion calculation unit 12 refers to the tool number α of the used mold specified by the GOO command and selects the metal corresponding to the tool from the mold corner nib program memory 8. Read out the square nib four-gram MMP.

That is, the mold angle nib program MMP stores mold machining programs MMP-MMP, etc. corresponding to molds having various shapes, as shown in FIGS. 18 to 20, for example. Nibrogram MMP (see Fig. 18) is a mold having the dimensions shown in Fig. 3 (w1 dimension 1
This is a program consisting of a plurality of movement commands MAD for machining a hole of the same shape as that punched by a die with a square punching shape set to a horizontal dimension y1 and a rotation angle θ, using a laser beam machine. This mold square Nibrogram MMP is,
The reference point sp is set at the center of the hole 15 to be machined. Therefore, by specifying the coordinate position of the reference point sp, the machining path for machining the hole 15 can be determined by following the mold square nib program MMP. The calculation is immediately determined. Note that point PA in FIG. 3 is the piercing position described above.

Also, among the G codes in the mold machining program MMP, G
OO means fast forward, GOI means linear interpolation, G02 means CW circular interpolation, and GO3 means CCW circular interpolation.

In addition, the mold square nibogram MMP2 (see Fig. 19) is a multi-movement machine for processing a hole of the same shape as that punched by a circular mold with a radius r using a laser processing machine, as shown in Fig. 4. This is a program consisting of command MAD. In this mold square nib program MVP, the reference point SP is set at the center of the hole 15 to be machined.
By specifying the coordinate position of P, the hole 15
The machining path for machining is the mold square Nibrogram MM
The calculation is immediately determined by P. Note that point PA in FIG. 4 is the piercing position described above.

In addition, the mold square nibogram MMP3 (see Fig. 20) has the same shape as punched with an oval mold whose vertical dimension is X1, horizontal dimension is y, and the rotation angle of the mold is θ, as shown in Fig. 5. This is a program consisting of a number of movement commands MAD for machining a hole with a laser beam machine.゛In this mold machining nib 4-gram MMP3, the reference point sp is set at the center of the hole 15 to be machined. Therefore, by specifying the coordinate position of the reference point sp, the hole 15 can be machined. The machining path for this is immediately calculated and determined by the mold machining program MMP. Note that point PA in FIG. 5 is the piercing position described above.

By the way, in step S1 of subroutine 5UBI shown in FIG. 21, the reference position S in FIGS.
A coordinate conversion operation is executed to set P to the punch position (x, y) shown in the GOO single punch command of the turret punch press shown in FIG.
) is the reference position SP of each mold machining program MMP. Then, the piercing position PA is as shown in FIGS. 18 to 20.
Each x1Y coordinate Δx1Δy indicated in the Goo command shown in the figure
is immediately calculated by a coordinate conversion operation of adding the punch position (x, y) of the turret punch press to . As a result, if the piercing position PA is calculated as (X+ΔX1y+Δy), the fast forward command generated in step S1 becomes GOOXx+Δx Y z.

Next, subroutine SUB 1 enters step S2,
Fast forward command GO that includes the M code command for laser oscillation
Then, in step S3, the mold machining program MMP corresponding to the tool number a specified by the 000 command is read in the machining program PPR of the turret punch press, and the M created in step S2 is Connect after code directive. As a result, the laser processing machine
With the GOO command generated in step S1, the piercing position is fast-forwarded, the laser oscillator is driven in step S2, and the hole 1 corresponding to the predetermined mold is driven in step S3.
5 is stored in the conversion program memory 13 for the laser processing machine.

In this way, the machining program for the hole 15 corresponding to the mold is
Once the converted program is stored in the gastrogram memory 13, in step S4, an M code instructing to stop laser oscillation is added to create a machining program for the laser beam machine that corresponds to the machining command for one block of the turret punch press. The conversion is complete.

When the conversion for one block is completed in this way, the program conversion calculation section 12 converts the punch press program memory 1 into the punch press program memory 1.
Read the next block related to the machining content of the turret punch press from the machining program PPR in 0 (therefore, commands unrelated to the machining content such as the reference point sp setting command and other control commands will be skipped) However, the mode of reading can be performed arbitrarily as necessary.)
.

The next read block is, for example, G2 shown in FIG.
In the case of the command No. 6 (Bolthole), the program conversion calculation section 12 reads the subroutine 5UB2 from the system program memory 11.

As shown in FIG. 22, subroutine SUB 2 is a program that converts the 026 command of the turret punch press into a movement command for the laser processing machine. In step S5, first, the block immediately before the G26 command is instructed by,
The coordinate positions of the centers of the n holes 15 to be machined are calculated from the seat m (X1Y) of the reference point sp set by the setting command of the reference point sp by G72. Next, in step S6, the conversion procedure from step S1 to step S4 of subroutine SUB1 is executed based on the calculated center position of each hole 15.

That is, in subroutine SUB 1, hole 150 reference point s
If the center position as p and the tool number α are known, a machining path for the laser beam machine is immediately generated for the hole 15, and in step S5, the standard for each hole 15 constituting the bolt hole is created. By calculating the coordinate position of point SP, it becomes possible to immediately generate a movement command for each hole 15. In this way, when a movement command is generated for the nil bolt hole hole 15 in step S7, a processing program for the laser processing machine corresponding to the bolt hole processing using the turret punch press is created in the conversion program memory 13.

Further, when the next block read by the program conversion calculation unit 12 is, for example, the command 028 (tenre) shown in FIG.
Read out.

Subroutine 5UB3 is a program that converts the G2B command into a movement command for the laser processing machine, and step 8
In B, first, from the coordinates (X, Y) of the reference point SP set by the reference point SP setting command by G72 or Goo, which is instructed in the block immediately before the cough G2B command (
In the case of the GOO command, conversion is performed by subroutine SUB 1 based on the 000 command, and the reference point SP is also processed. ), calculate the coordinate positions of the centers of the n holes 15 to be machined. Next, step S9
In the same way as in the case of subroutine 5UB2, subroutine SU is executed based on the calculated center position of each hole 15.
Executing the conversion procedure from step S1 to step S4 of B1, for the n holes 15 forming the tenlet,
A movement command is generated, and a processing program for the laser processing machine corresponding to the tenlet processing of the turret punch press is created in the conversion program memory 13.

Further, the next block read by the program conversion calculation unit 12 is, for example, G29 (arc) shown in FIG.

Y), calculate the coordinate positions of the centers of the n holes 15 to be machined. Next, step 812 is entered, and as in the case of subroutine 5UB2, each calculated hole 15 is
Based on the center position of the turret punch press, the conversion procedure is executed from step S1 to step S4 of subroutine SUB 1, a movement command is generated for the n holes 15 forming the arc, and the conversion program memory 13 is stored in the conversion program memory 13.

..., and finally, in step 824, the torch is returned to the reference point SP in 072 of the turret punch press command.

In this way, the 036 command is converted into other more sophisticated turret punch press commands such as G28, GOO1G72, etc. In step 825, each command is converted into a command for the laser processing machine according to the procedure already described, and then converted. stored in the four-gram memory 13.
