    Abstract: PROBLEM TO BE SOLVED: To more correctly comprehend a hole size and to more precisely machine a hole with a required opening area when laser-machining the hole with the opening area required for the enclosed edge in a tubular work.
    SOLUTION: When the tubular work W is irradiated with laser beams L, and the hole is laser-machined to the enclosed edge of the tubular work W, the temperature of the work rapidly increases, and assist gas fed from a feeding means to the inside of the tubular work is expanded, thus the amount of the assist gas to be fed into the tubular work measured by a measurement means 26 is made smaller than the actual flow rate of the assist gas. Then, by utilizing the phenomenon that the expansion amount of the assist gas at the inside of the tubular work W is made proportional to the output of a laser, the measured value of the feed of the assist gas is compensated by the reduction in the feed of the assist gas caused by the expansion of the assist gas. The size of the hole made in the enclosed edge in the tubular work W is obtained from the value after the compensation, and the correct hole size is comprehended.

    Abstract: PROBLEM TO BE SOLVED: To provide a hole machining method and a hole machining device capable of precisely machining a hole of the requested opening area in a closed end of a tubular workpiece. SOLUTION: In the hole machining method, a hole of the requested opening area is machined by feeding a pressurized assist gas in a tubular workpiece having a closed end, irradiating laser beams on the closed end, and grasping the hole diameter based on the outflow amount of the assist gas from the opened hole. While machining the hole, it can be determined that the dross is generated if relatively large fluctuations f 1 , f 2 of the assist gas flow Q occur corresponding to the ON/OFF time of laser beams with respect to the relatively small previous fluctuation of the assist gas outflow amount Q by turning off laser beams L once or several times. In such a case, the laser beam machining condition is changed so as to suppress the fluctuations f 1 , f 2 of the assist gas outflow amount Q. COPYRIGHT: (C)2008,JPO&INPIT
