With the AE signals captured during and immediately after the termination of laser cutting process, deterioration of the laser cut surface and occurrence of dross formation at the lower cut edge can be detected. It has been determined that captured AE signals offers very good information for controlling the laser cutting process in order to ensure high laser cut quality.
