Paper Abstract

Oxygen-assisted laser cutting of low-carbon steel with a fiber laser is studied experimentally. The objective of the work is to find the link between the cutting quality (which is low roughness and no dross) and energy characteristics of the cutting. Cutting parameters are expressed though two dimensionless complexes, namely the Peclet number and dimensionless laser power. It is founded that for the cutting with minimal roughness, the Peclet number is of 0.35…0.4, and the contribution of the absorbed laser energy in the unit of removed material volume is 12…14 J/mm3 for sheets of 3, 5, and 10 mm. The results are compared to the data obtained for the СО2 laser.
