LASER MACHINING METHOD AND LASER MACHINING APPARATUS

摘要

A laser machining method includes forming a through-hole (5) in a workpiece (6) by emitting a laser light (29); generating image data by taking an image, with a camera, of the workpiece in which the through-hole (5) is formed; and adjusting a hole diameter of the through-hole (5) by enlarging the hole diameter of the through-hole (5) based on the generated image data.
