Abstract
Optimization of the fibre laser cutting parameters for attainment of high cut edge
quality in 10 mm stainless steel plate was demonstrated in this study. The tested process parameters
included cutting speed, focal position, and focal length. Optimization of these process
parameters enhances the melt removal from the cut kerf so as to prevent the undesired dross
adherence on the lower cut edge or even incomplete penetration of the workpiece when the
incident intensity is not sufficient to penetrate the workpiece. Dross-free cut edges with lower
surface roughness and lower deviation of cut edge squareness could be achieved by reducing
the cutting speed from the maximum achievable value, using the longer focal length lens for
focusing the laser beam, and with focal position located on the bottom workpiece surface. These
conditions enhance a high melt removal rate resulting in a high cut edge quality.
