THREE-DIMENSIONAL LASER PROCESSING MACHINE

摘要

A three-dimensional laser processing machine performs high-precision laser processing on a workpiece (W) by setting the focal position of laser light to be condensed by a condensing lens at a predetermined distance from a portion to be processed of the workpiece (W), is provided with a three-dimensional shape measuring instrument (50) for measuring the three-dimensional shape of the workpiece (W), and sets the focal position of the laser light at the predetermined distance from the portion to be processed on the basis of three-dimensional shape data relating to the workpiece (W) measured by the three-dimensional shape measuring instrument (50).
