Method for processing material with laser having scanner mirrors by temperature sensor coupled in the beam path, comprises correcting the optical distortion between radiation source and sensor depending on the deflection of the mirrors

摘要

The method for processing material with a laser (L) having scanner mirrors (SS) by a temperature sensor (K) such as camera coupled in the beam path, comprises correcting the optical distortion between radiation source and the sensor depending on the deflection of the scanner mirrors. The camera evaluates the picture to measure the position of an object. The performance of the laser is controlled in relation to the temperature signal of the sensor. The treatment takes place at working positions in a quasi-simultaneous manner. The output signals of the sensor are triggered. The method for processing material with a laser (L) having scanner mirrors (SS) by a temperature sensor (K) such as camera coupled in the beam path, comprises correcting the optical distortion between radiation source and the sensor depending on the deflection of the scanner mirrors. The camera evaluates the picture to measure the position of an object. The performance of the laser is controlled in relation to the temperature signal of the sensor. The treatment takes place at working positions in a quasi-simultaneous manner. The output signals of the sensor are triggered and assigned to different sequences, so that a sequence contains the measured values of individual working positions. The provided sequence of pictures provides a visual observation of the treatment process. The sequences of the temperature-measured values are used for independent power regulation at the individual working positions. An independent claim is included for a device for material processing with a laser.
