Laser pulse overlap was varied to optimize overlap values for best edge quality and for best ablation rate. From the results some guidelines for complete cutting of thin sheets were derived. For an acceptable edge quality a maximum ablation rate of 2.6 mm³/min was demonstrated for stainless steel thin sheets, whereas up to 9,4 mm³/min have been reached for polycarbonate. For SUS304 the use of the SHG does not increase ablation rate or edge quality, whereas for polycarbonate the cutting quality is better, but at a smaller ablation rate. |
