                    AREAS OF APPLICATION                                                    TECHNOLOGICAL IMPACT

                    Active Speed Control is used for laser flame cutting and fusion         Setting the cutting speed to an optimum value both increases the reliability
                    cutting of two-dimensional contours in mild and stainless steel         of the cutting process and ensures productivity close to the possible maxi-
                    sheets. Laser powers from 8 kW to 12 kW and a sheet thickness           mum given by the set of material properties, ambient conditions and the
                    range from 4 mm to 25 mm are supported. The sensor concept              condition of the cutting tool. At the same time, the system offers potential
                    is transferable to other material types, laser powers, and sheet        for controlling or monitoring further process parameters. Thus, it is a fun-
