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 …

The geometry of the cutting front and the cutting kerf was measured with an online high-
speed x-ray diagnostic system. X-ray videos from fusion cutting of 10 mm thick stainless …

The transition from stable laser cutting conditions to an incomplete cut, which is generally
referred to as loss of cut, limits the maximum feed rate of laser beam cutting. In order to …

Abstract 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 …

High-speed videos of the cut front and spectrometric measurements were applied to detect
local vaporization on the cut front at high cutting speeds to show that with increasing feed …

The problem of variable susceptibility to dross formation or cast-to-cast variations in the
performance of solid-state laser fusion cutting of 2 mm stainless steel sheets is investigated …

The melt flow velocity and the local surface angles of the cutting front during laser fusion
cutting of 10 mm AISI 304 were determined for a laser power of 8 kW and a feed rate of 2 …

The authors report on a monitoring system for fiber laser fusion cutting based on a high-
speed camera with spectral sensitivity in the visible spectral range. Without external …

The 3D geometry of the interaction zone in laser material processing is of major importance
as it defines the absorption of the laser beam and may influence the hydrodynamics of the …

Burr formation during laser cutting of thin sheet metal significantly impairs the process
quality. It is especially observed in case of high cutting velocities close to the cutting limit …
