Abstract
According to a laser cutting method, a processed part is laser-cut so that the processed part doesn't drop off from a sheet-shaped workpiece. In the laser cutting method, a cut slit of a pressing protrusion, which is curved due to a laser cutting process along an outline of the processed part and then presses a peripheral surface of the processed part, is preliminarily formed around the processed part to be cut out from the workpiece. Then, the laser cutting process is carried out along the outline of the processed part. The pressing protrusion curves toward the processed part due to the laser cutting process of the processed part, and then the processed part is retained by the pressing protrusion.
