ABSTRACT
Laser-beam machining is a non-conventional machining process. Laser-beam machining is a thermal material-removal process that utilizes a high-energy, coherent light beam to melt and vaporize particles on the surface of metallic and non-metallic workpieces. LBM is newer thermal technique also widely accepted in industry today. Laser beam machining is based on the conversion of electrical energy into light energy and then to thermal energy. The main purpose of this paper is to analyse the impact of the parameters associated with the CO2 laser cutting of the micro slot having a width of 0.3 mm and a length of 20 mm on a copper plate of 4 mm thickness. Micro-slots or micro-channels are one such type of feature which has more applications in the fabrication of miniature devices, micro-fluidic devices or heat exchangers. The experiments are planned and conducted on the basis of the typical L27 Taguchi orthogonal array with three laser cutting parameters viz. Laser power, gas pressure, cutting speed and organised at three stages. The result showed that the parameter like power has greater influence on MRR and cutting Speed has greater influence on Kerf Width and gas pressure has less significance compare to both.
