Output control method of fiber laser processing machine and fiber laser processing machine

摘要

A fiber laser oscillator having a plurality of fiber laser modules each of which generates a laser beam, a laser processing head for emitting a laser beam generated from the fiber laser oscillator, a laser processing head provided between the work and the laser processing head, And a focusing lens having a predetermined focal length for irradiating the workpiece with a spot diameter according to a laser beam from the head, the method comprising the steps of: irradiating the workpiece with a laser beam having a spot diameter corresponding to a workpiece By adjusting the number of oscillations of a plurality of fiber laser modules, the beam quality from the laser processing head is adjusted.
