Research collaborators from Fraunhofer Institute of Laser Technology (ILT), KOSTAL Kontakt Systeme GmbH, Amphos GmbH, and Pulsar Photonics GmbH have combined the precision and quality of helical drilling and the efficiency of multibeam processing to enhance the performance of sheet metal parts cutting. The merging of processes aims to establish a single process that meets the accuracy and speed requirements of industrial-level production.
A high-power beam source with an output power of 300 W and pulse energy of 3 mJ performs the cutting. High pulse energy is necessary to divide the beam — sometimes into as many as 20 additional beams. The system retains the benefits in precision of helical drilling, which in the research takes…READ MORE
