Laser cutting is a thermal cutting process based on material melting that results in characteristic features of the cut edge. The dross in particular is a crucial quality-determining feature which occurs especially when processing higher sheet thickn

The latest research on laser beam fusion cutting (LBFC) with static beam shaping have shown a limitation in the quality of cut parts for thick steel plates (> 6 mm) when using solid state lasers. The approach of dynamic beam oscillation has recently

In this work, the impact of laser cutting and a subsequent pre-deformation on the fatigue behavior of AISI 304 was investigated. This represents a typical process chain in steel sheet manufacturing. Laser cutting trials with variating process paramet

Dynamic beam shaping brings a large potential for the laser cutting process by increasing the cutting speed and improving the cut edge quality. However, laser beam oscillation is almost exclusively realized with 2-mirror galvanometer scanners that li

3D measurements of the cutting fronts during laser fusion cutting were performed with and without beam oscillation. The used 3D measurement equipment offers up to 75.000 frames per second and a local resolution less 50 µm. This allows high-speed rec

Since the emergence of high power single mode fiber lasers cutting velocities of more than 100 m/min can be achieved easily on a straight cut. Results of laser fusion cutting of thin sheet metal with a 2 kW single mode fiber and 4 kW laser will be in
