摘要：Laser cutting is energy based unconventional process used to cut complicated shapes of various types ofmaterials. The objective of this paper is to investigate the effects of parameters associated with CO2 laser cutting ofAluminium plate of 6 mm thickness. The experiment was designed and carried out on the basis of standard L9Taguchi’s orthogonal array in which the four laser cutting parameters viz. laser power, cutting speed, assist gaspressure, and stand-off distance were arranged at three levels. The width of laser cut or kerf, quality of the cut edges areaffected by laser power, cutting speed, assist gas pressure, and stand-off distance between nozzle and the work-piecematerial. The relations between the input parameters and the response were investigated. The result showed that theparameters like power, cutting speed and stand-off distance have major impact over surface roughness and kerf width.
