PURPOSE:To exactly execute the coping and the management and to reduce useless working and failure working, etc., by detecting heat generated in the vicinity of a laser nozzle by a temperature sensor provided on the outside peripheral part of the laser nozzle. CONSTITUTION:Many pieces of temperature sensors 3 are provided on the periphery of a nozzle center 31 of a laser nozzle 1, and by executing an input to a numerical controller N through an amplifier 43, a prescribed control is executed. Subsequently, a laser beam LB oscillated by a laser oscillating device irradiates the work W surface of the lower face from the laser nozzle 1 and the moving work W is brought to cutting to a prescribed shape. In the case the laser beam LB in this laser nozzle 1 generates a temperature variation due to some cause, the temperature sensor 3 detects it. In such a way, by stopping the working work temporarily, and controlling a laser intensity adjusting device by an automatic control, etc., a correct working condition is set. |
