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.
