ABSTRACT:
A laser machining system for machining a plurality of different machining spots on a work, which comprises a laser oscillator for generating laser light; a laser light scanner for deflecting the laser light generated from the laser oscillator so as to sequentially irradiate the laser light to the plurality of variable machining spots on the work; an irradiation time setting member for determining previously a laser irradiation time for machining one machining spot on the work in one operation; and a controller for controlling the laser light scanner to sequentially move the machining spots in a time division fashion so that the laser irradiation time to machine each machining spot in one operation does not exceed the determined irradiation time. Thus, this laser machining system can perform laser machining with high precision at a machining rate as high as possible with a thermal effect prevented.
