ABSTRACT:
A laser cutting machine in which a laser beam is condensed by a machining lens, and while the laser beam thus condensed is being applied to a workpiece, the laser beam and the workpiece are moved relative to each other, to cut the workpiece, the laser cutting machine comprising optical axis moving means for moving the laser beam applied to the machining lens in parallel with an optical axis to a desired position on the machining lens, and optical axis movement control means for controlling the optical axis moving means in conformance with a program provided for a cutting locus to control the relative movement of the condensed laser beam and workpiece, so that the laser cutting machine which is not expensive, and can form a cut in a workpiece in such a manner that the cut is not tapered in section, without lowering the machining accuracy is obtained.
