PURPOSE:To permit laser beam processing with high accuracy in a post stage of combined processing by picking up the image of a reference hole on a work surface by a light transmission type image pickup means using visible light laser, taking in an image pickup signal and determining the laser beam processing position relative to the reference hole. CONSTITUTION:The work W is positioned on a stationary table 3 by an X-Y carriage 5 controlled by a NC unit 21 and is subjected to processing by projecting a laser beam LB such as CO2 outputted by a laser beam generator 11 from a processing head 13. The visible light laser lb for adjusting the processing beam is projected atop the work W and the image of the reference hole 25 is picked up by a camera 17 at the time of starting the processing. The NC unit 21 makes prescribed correction on the bases of the central position of the image of the hole 25 and controls the carriage 5 so as to make the prescribed processing relative to the hole 25 when an image processor 19 takes in the image pickup signal and calculates the central position of said image of the hole 25. The high-accuracy laser beam processing is thereby permitted in the post stage of the combined processing. |
