Role of the Laser Focus Position in the Laser Beam Cutting of Thin Stainless Steel Sheets

Abstract:

This paper examines pulsed Nd:YAG laser cutting edge quality of 0,4 mm thin AISI 304L austenitic stainless steel sheets. We analyze the effect of laser beam focal plane distance from the upper plane of the sheet and the effect of cutting speed on the striation of the cutting edge. We obtain the acceptable focus position range from the analysis of percussion drilling. At the evaluation we determine the optimal focus position for the maximal cutting speed.
