Al6061 find wide applications in aerospace and automotive industries. The challenge lies in cutting this advanced material and obtain the good surface texture. The present study reports the application of non-contact type (thermal energy based) bystronic fibre laser cutting process on Al6061. The process parameter in laser cutting influence the kerf width and surface roughness. These quality characteristics were observed for the various combination of cutting parameter like laser power, feed rate and assist gas pressure. The cutting trial were design according to box behnken method and grey based response surface methodology was disclosed for predicting optimal combination laser cutting parameters substantial improvement in surface finish was observed in the response obtained with the optimal setting of parameters.
