Zusammenfassung:	PURPOSE:To provide a laser beam machining method where the excellent laser beam machining is achieved under appropriate machining conditions even when the machining is achieved in a closed condition. CONSTITUTION:When a work W is heated with the laser beam, and the measured value of the surface temperature of the work W exceeds either of the first to fourth reference values, the correction levels (1)-(4) corresponding to the exceeded reference value are judged, and the data on the machining conditions to be read from a machining condition storage part 23 are corrected and operated based on the items of the machining conditions and the ratio of correction which are the corrective data corresponding to the respective correction levels (1)-(4) to be stored in a correction data storage part 24. These corrected data on the machining conditions are outputted to a laser control part 10, a sequence part 20 and a numerical value control part 19. This constitution achieves the laser beam machining under appropriate machining conditions to be corrected according to the temperature of the work W.
