Pulsed Nd:YAG laser is used for the purpose of cutting of 8011 sheet of aluminium. Highly reflective and thermally conductive sheets can be cut suitably with the help of laser. Qualitatively cutting of sheets have to be depended on the properties of the materials like optical and thermal. Due to the highly reflective surface of the work material i.e. aluminium sheet which is not possible to cut preciously with the help of any other machining processes. Wavelength of Nd:YAG laser is having 1.06 µm which is less as compared to CO2 laser (10.6 µm). Wide uses of the aluminium alloy thermally conductive material in technologically advanced industrial sectors like aerospace and automobile. Complex shapes and stringent design can be cut preciously by proper controlling of the input parameters. Nd:Y3 Al5 O12 laser has widely used for the cutting of these materials therefore it has more value for the technologically advanced industrial sectors like aerospace, automobile. Complex shapes and stringent design can be cut accurately by proper controlling of the input parameters. This paper is shown the parameters optimization for lesser kerf quality i.e deviation in kerf during laser cutting. Taguchi methodology selected for determining the optimal inputvariables for cutting.
