Craterlike structures and surface roughness of laser cut
Abstract
Characteristics of craterlike structures on the laser cut surface and their dependence on surface roughness are experimentally studied for sheet thickness of 3-16 mm. The crater size and the number of craters increase with the sheet thickness. The dependence of the number of craters on the cutting velocity is nonmonotonic and has a peak. This peak is observed at an optimal cutting velocity, which ensures the minimum roughness of the cut surface. A qualitative explanation of the observed phenomena is proposed.
