PURPOSE:To reduce a melting loss of acute angle cutting, and to execute laser working with high quality and with high accuracy by providing a work moving speed detecting means, an optimum laser output recording means, an optimum laser output determining means, and a laser output control means, on a laser working device. CONSTITUTION:A titled laser working device is provided with a speed detector 12 for detecting a relative moving speed for a workpiece 1 of a laser beam 3 irradiated on the workpiece 1, an optimum laser output recording means for recording an optimum laser output to the relative moving speed corresponding to a material quality and the plate thickness of the workpiece 1,a microcomputer 13 which also serves as an optimum laser output determining means for determining an optimum laser output by a detecting signal from the speed detector 12 based on recording of the optimum laser output recording means, and a laser output control means 14 for controlling an output of a laser oscillator 2 based on a output of the optimum laser output determining means. With respect to a cutting part of a complicated shape, laser working which scarcely causes a melting loss by thermal saturation can be executed. |
