PURPOSE:To obtain a laser beam machine damaging neither work head nor clamp by providing the XY table which stops by the movement to an operation limit, the change-over switch reactuating a laser oscillator and the signal lamp lit by the change-over of the change-over switch. CONSTITUTION:When a limit value 5 exceeds a work head 1 in case of working a work part 6, a work table 3 and laser oscillator become in a field holding state, a display lamp 10 is lit and the damage of a work head, etc. is prevented. When the positions of the work part 6 and a clamp 4 are confirmed and it is judged all right to continue working as it is, a change-over switch 8 is shifted, an operation reopening switch 11 is turned on and the working is executed with confirming that the work head 1 and clamp 4 are not interfering. Even when a work part 7 is worked, the display lamp 10 is lit when the limit line 5 exceeds the work head 1, so working is executed with confirming the lamp 4 and work head 1 not interfering. |
