Abstract: |
The generation of low surface roughness of the cut edge during laser beam cutting is a challenge. The striation pattern, which determines the surface roughness, can be distinguished into regular and interrupted striations, the latter resulting in an increased surface roughness. In order to analyse their formation, the space- and time-resolved cutting front geometry and melt film thickness were captured during laser beam fusion cutting of 2 mm thick samples of aluminium with a framerate of 1000 Hz by means of high-speed synchrotron X-ray imaging. Red, yellow and white colored areas show the shape of the cutting front and cutting kerf; P = 1 kW, v = 1.75 m/min. |
