    摘要： In the present invention, a laser beam with a prespecified oscillation frequency is divided into the arbitrary number of pulses to be irradiated to all holes in an area, and this step is repeated until the irradiation reaches a desired number of pulses, whereby an interactive time can be decided according to the number of divided pulses and a cooling period of time can be obtained, and also the number of pulses per one division is set to be a plurality of pulses, which allows an etching rate to be increased, so that the number of pulses required for machining can be reduced as compared to a case where a laser is irradiated to all the holes pulse by pulse.

    摘要： A laser cutting method is provided for laser cutting a workpiece made of a metallic material to form hole having a desired shape, in which many of a second set of laser cutting conditions are different from a set of first laser cutting conditions, in order to avoid a chipping phenomenon when switching laser cutting conditions. The first laser cutting conditions are used for cutting the workpiece up to a predetermined distance short of the end point of the cut. The second set of cutting conditions are used for cutting the workpiece between an end point of the cut along the circumference of the hole, and a point a predetermined distance short of the end point of the cut. The focus position in the second laser cutting conditions is the same as the focus position in the first laser cutting conditions. Moreover, other of the second cutting conditions are the same as corresponding ones of the first set of cutting conditions.
