Document Type and Number:
Japanese Patent JP5816370
Kind Code:
B2
Abstract:
There is provided a power control method for a fiber laser processing machine including: a fiber laser oscillator having a plurality of fiber laser modules each of which generates a laser beam; a laser processing head for emitting the laser beam generated from the fiber laser oscillator; and a condenser lens with a prescribed focal length provided between a workpiece and the laser processing head, for irradiating the workpiece with the laser beam having a spot diameter output from the laser processing head, wherein the number of the plurality of fiber laser modules oscillated is adjusted so as to achieve the spot diameter corresponding to the workpiece, and thereby, a beam quality from the laser processing head is adjusted.
