<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining method and a laser beam machining device where, when holes are formed in an almost square sheet-shaped work having flexibility, the reduction of cost and the increase of the precision in the forming positions of the holes can be attained. <P>SOLUTION: In a state where a point P1 in a corner part A1 in a work S is fixed, tension is applied to a point P2 in a corner part A2 adjacent to the corner part A1 in a direction of a straight line passing through the point P1 and the point P2. Further, tension is applied to a point P3 in a corner part A3 and a point P4 in a corner part A4 in optional directions, so as to stretch the work S. Then, in a state where the work S is stretched, laser light is emitted to prescribed positions in the work S, so as to form holes. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
