Process monitoring and closed loop control during high-speed laser beam cutting
Abstract
Methods and setup are presented for quality assurance and machine control of laser-slitting lines, used for cutting thin metal sheets. Optimal cutting speed is guaranteed by a closed loop process control. Critical cutting process conditions are detected. Further a reflex light barrier controls the cutting result. During machine setup times the process control detector is used for automatic adjustment of the cutting head concerning focal point position.
