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.

A laser machining machine having a laser oscillator and a machining head communicating with each other through a propagation path for controlling a length of the propagation path in response to a position of the machining head, said laser machining machine comprising;
- machining area setting means for dividing a machining area at given intervals;
- optical path position setting means for setting an optical path position responsive to the machining area;
- and
- optical path length control means for detecting a position of the machining head and controlling an optical path length in response to the optical path position set in said optical path position setting means.
In 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, a laser machining method comprising the steps of:
- detecting a current position of the machining head;
- determining whether or not the current position of the machining head is in a predetermined machining area;
- and
- if the current position of the machining head is not in the predetermined machining area as the result of the determination, controlling the optical path length to adjust the propagation path, and if the current position of the machining head is in the predetermined area, suppressing controlling of the optical path length.
