Fibre laser cutting of thin section mild steel: an explanation of the 'striation free' effect
Powell, J. and Al-Mashikhi, S.O. and Kaplan, A.F.H. and Voisey, K.T. (2011) Fibre laser cutting of thin section mild steel: an explanation of the 'striation free' effect. Optics and Lasers in Engineering, 49 (8). pp. 1069-1075. ISSN 0143-8166
This paper presents the results of an experimental and theoretical investigation into the phenomenon of 'striation free cutting', which is a feature of fibre laser/oxygen cutting of thin section mild steel. The paper concludes that the creation of very low roughness edges is related to an optimisation of the cut front geometry when the cut front is inclined at angles close to the Brewster angle for the laser-material combination.
