Abstract
A laser machining machine having a laser oscillator and a machining head communicating with each other through a propagation path for controlling the length of the propagation path in response to the position of the machining head. The laser machining machine divides a machining area at given intervals, and then sets an optical path position responsive to the machining area. The machine further detects the position of the machining head and controls the optical path length in response to the set optical path position.
