| 摘要 |
A laser processing machine includes a laser processing head including a beam guide for deflecting and/or focusing laser radiation onto a workpiece; a thermo-sensitive monitoring sensor system for an optical component of the beam guide; and an evaluation unit connected to a machine control of a laser generator that produces the laser radiation and configured to receive and process the data acquired by the monitoring sensor system. The evaluation unit attributes an increase in the temperature of the optical component of the beam guide due to laser radiation reflected from the workpiece to defective cutting.
