Abstract
A laser machining apparatus with a simplified laser beam transmitting network. Respective laser beams form laser generators LS# to LS# divided into groups of G and G are aggregated to fiber-optic cables H and H by confluence devices HC and HC and transmitted to a most upstream laser beam outlet OP The laser beams are further aggregated to a fiber-optic cable H and distributed to a branch fiber-optic cable HH by the laser beam outlet OP and then distributed by laser beam outlet OP to OP to branch fiber-optic cables HH to HH The laser beams distributed to branch fiber-optic cables are focused by the machining tools TL to TL attached to robots RB to RB for laser machining. By controlling output levels of the laser generators with different oscillation wavelengths and different polarization characteristics, blend ratio of the laser beams can be adjusted. Distribution ratios of the laser beams at the laser beam outlets OP to OP are adjustable.
