Laser processing method and laser cutting systems of high molecular workpieces

Abstract

The invention belongs to the technical field of laser processing, and discloses a laser processing method of high molecular workpieces. Two laser cutting heads irradiate the workpieces with two laser beams with different power values, the high-power laser beam moves along a processing track of the workpieces to cut the workpieces by a certain distance, and then the low-power laser beam moves along the processing track of the high-power laser beam for cutting. The invention further discloses two laser cutting systems for realizing the laser processing method, one laser cutting system comprises two laser oscillators, two laser drivers, two industrial personal computers and the two laser cutting heads, and the high-power laser beam and the low-power laser beam can independently controlled to be transmitted; the other laser cutting system comprises a laser oscillator, a laser driver, an industrial personal computer, the two laser cutting heads and a beam splitter used for splitting a laser beam transmitted by the laser oscillator to a high-power laser beam and a low-power laser beam.
