<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining method capable of smoothly surfaced tapered three-dimensional machining. <P>SOLUTION: In the laser beam machining method in which a prescribed shape is machined on a workpiece 19 by irradiating it with a laser beam through a mask 41 and an image-forming lens 14, the machining is performed by arranging the workpiece 19 before the image-forming position of the image forming lens 14, so that the smoothly surfaced tapered three-dimensional machining is realized. <P>COPYRIGHT: (C)2003,JPO</p> |
