  • Laser beam machining apparatus and laser beam machining method
    Patent number: 6680459
    Abstract: A laser beam machining apparatus forms blind holes at predetermined intervals in a workpiece by intermittently irradiating a laser beam from a laser nozzle to the workpiece while the laser nozzle and the workpiece being moved relatively. During the time the workpiece is subjected to machining, the electrostatic capacity between the support member and the laser nozzle is detected by an electrostatic capacity sensor while the workpiece made of conductive material is supported on the support member. The irradiation output power is controlled by a control unit which operates to vary the number of output pulses from the laser nozzle each time one hole is formed according to the result detected in response to variation in the thickness of the workpiece.
