Abstract
A laser cutting method employs at least two sensors which are operative during the cutting operation to monitor process parameters and send signals indicative of the monitored parameters determining parameters of the cutting operation in which are indicative of the status of the penetration of the workpiece. The signals from each of the sensors is evaluated by comparing the sensed parameters in the signals with usability criteria to determine the usability of the signals. The signal which compares most favorably with the usability criteria therefor is transmitted to the controller to modify the parameters for the cutting workpiece. In the absence of a control signal from the evaluation, the controller proceeds with the cutting in accordance with parameters which are then operative in the controller. Generally, the selected signal effects the speed of relative movement between the workpiece and cutting head.
