Title:
LASER PROCESSING MACHINE, AND ARITHMETIC DEVICE FOR LASER PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/078730
Kind Code:
A1
Abstract:
A laser processing machine (1) is provided with: a plurality of laser modules (41) that generate laser beams (La); and a combiner (42), which collects the laser beams (La) generated by the laser modules (41), and outputs the laser beams as one laser beam (L). The laser processing machine (1) is also provided with: a plurality of driving power supplies (43) that respectively supply power to the corresponding laser modules (41); an arithmetic device (70) that calculates, corresponding to received processing conditions, drive conditions of each of the laser modules (41); and a power supply control device (80) for supplying power from the driving power supplies (43) to the laser modules (41) in accordance with the drive conditions. The arithmetic device (70) controls a power supply control device (80) so that differences among laser output integrated times of the laser beams (La) respectively generated by the laser modules (41) are small.
