ラムを作成していた。(b), Prior Art In order to perform cutting or the like on a workpiece in a conventional laser processing machine, the workpiece to be processed is first supported by a plurality of workpiece supporting members formed in the shape of a crest fixed to a table. Next, in this state, the table and the laser processing head installed above the table are moved and driven as appropriate based on the machine program, and the laser beam is emitted from the laser processing head toward the workpiece H3 to achieve a predetermined target. Carry out mechanical work. At this time, when the laser processing head faces the workpiece support member with the workpiece in between, the laser beam emitted from the laser processing head is blocked by the workpiece support member and cannot penetrate the workpiece. Good machining cannot be performed. Therefore, conventionally, a carnivorous program has been created so that the laser processing head does not face the workpiece support member during processing.

位置（図示せず）上に位置決めする。Since the laser processing machine 1 has the above-mentioned configuration, at the 9th time when a workpiece is to be cut, the workpiece 17 to be processed is placed at a predetermined position on the workpiece support surface 3b of the table 3 shown in FIG. Workpiece contact portion I of the plurality of workpiece support members 11
Mount it so that it is in contact with L=c. When the workpiece 17 is almost mounted at a predetermined position, a cutting program for the workpiece 17 is executed to perform a predetermined cutting process on the workpiece 17. That is, based on the cutting program, the laser processing head 6 is The tip 6a of the laser processing head 6 is moved in the direction of arrow C or D, and the tip 6a is moved in the direction of arrow F, and the table 3 is moved and driven together with the workpiece 17 in the direction of arrow A-B. is positioned above the machining start position (not shown) of the workpiece 17.

動駆動させる。In this way, when the tip 6a of the laser processing head 6 is positioned at the processing start position, a laser beam is emitted from the tip 6a toward the workpiece 17, and in this state, the laser processing head 6 is moved in the direction of the arrow C1D. Furthermore, the table 3 is appropriately moved along with the workpiece 17 in the direction of the arrow AB.
すると、先端部６ａから射出されたレーザ光線は。Then, the laser beam emitted from the tip 6a.

。In this way, when the laser processing head 6 cuts the wire 17 by moving the table 3 down in the directions A and B in FIG. For example, the workpiece support member 11 on the right side of FIG.
When the ring is located in the opposite direction, the position detection switch 13 corresponding to the workpiece support member 11 comes into contact with the dog 15.

In response to this, the drive cylinder control section 16 drives the drive cylinder 12 connected to the workpiece support member 11 on the right side of FIG. 1 to move the rod 12a backward in the direction of arrow F.

支持面３ｂ上の所定位置からズレルようなことはない。Then, the workpiece support member 11 moves in the direction F while being pulled by the rod 12a, and each workpiece welding part 11c of the support member 11 moves away from the workpiece support surface 3b, and therefore from the workpiece 17, and moves downward in the figure. The workpiece 17 is moved and retracted to a position moved by a predetermined distance (hereinafter referred to as a retracted position). Note that even if the workpiece support member 11 is retracted from the workpiece 17, the workpiece 17 is still surrounded by a large number of workpiece support members. Since the workpiece 17 is supported by the workpiece support surface 3b, the workpiece 17 will not be displaced from the predetermined position on the workpiece support surface 3b.

Therefore, the portion of the workpiece 17 that is hit by the machining path by the laser beam emitted from the tip portion 6a is not obstructed by the workpiece support member 11 and moves along the arrow E,
It is penetrated in the F direction and cutting can be performed without any problem.

Then, the contact relationship between the position detection switch 13 and the dock 15 is released, and the 1-position detection signal is no longer output from the switch 13 to the drive cylinder control section 16. Then, in response to this, the drive cylinder control section 16 causes the rod 12a of the drive cylinder 12, which had been retreated in the F direction, to protrude in the arrow E direction. Then, the workpiece support member 11 on the right side of FIG. 1 is pushed up by the rod 12a, rises a predetermined distance from the retracted position, and returns to the position shown by the solid line in FIG.
Workpiece 17 mounted at a predetermined position on workpiece support surface 3b

同様に、先端部６ａの第１図下方に、今度は図中左方の
ワーク支持部材１１が位置した際にも。Similarly, when the workpiece support member 11 on the left side in the figure is positioned below the tip portion 6a in FIG.
該ワーク支持部材１１が、退避位置まで移動退避される
ので、ワーク１７に対して支障なく切断加工を行なうこ
とが出来る。Since the workpiece support member 11 is moved and retracted to the retracted position, the workpiece 17 can be cut without any hindrance.
