چکیده
Laser cutting is widely used thermal energy based non-contact type, nonconvectional machining process. In the present research, the effect of laser machine processing parameters such as laser power, gas pressure, cutting speed and thickness effect on measured response such as surface roughness. The experiment was designed according to Taguchi L27 orthogonal array with three different level of each input parameter. For result interpretation, analysis of variance (ANOVA) was conducted and optimum parameter is selected on the basis of the signal to noise ratio, which confirms the experimental result. The result indicated that cutting speed and work piece thickness play important role in surface roughness. Keywords— CO2 laser, Hardox-400, Laser cutting, Taguchi method

An explanation of ‘striation free’ cutting of mild steel by fibre laser
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 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 th...
