ABSTRACT:
A Laser beam machining is carried out by irradiating beforehand the laser beam along a final locus for a main machining, under such a condition as to obtain an energy density for forming a groove angled to a surface of a work. Thereafter, the laser beam is irradiated to the groove, while changing only the energy density according to a cutting condition to cut the work.
