Lasers in Manufacturing 2013 location:Munich date:May 13-16, 2013
In this paper a high-dynamic cutting machine equipped with a recently developed 2kW diode laser source is introduced and compared with the commonly used lasers. The beam profile and characteristics of the diode laser are compared with those of a typical 4kW CO2 and a 2kW fibre laser source. The consumption of electric energy is measured for the three sources under identical cutting conditions. Several samples cut with optimized parameter settings are presented, illustrating the practicality of direct diode lasers for high-quality sheet metal cutting at industrially relevant speeds.
