Beam penetration detection method for laser machining |
摘要 |
The method uses at least one sensor for detecting the intensity of the radiation received from the machining point between the laser beam and the workpiece, for providing a status signal in response to a given intensity variation. At least two mean values (M1,M2) for the detected radiation intensity are provided using different time constants, with the status signal supplied when the mean values have a given relationship to one another.
