Abstract: This work proposes the investigation of machining time and vibration characteristics of machining differently oriented unidirectional carbon fibre reinforced polymer (CFRP). The carbon fibres are oriented at 0, 45, 90 degrees during stacking process of laminate. The turning experiments are carried out on a Siemens-CNC lathe to investigate best operating conditions. Nine experiments based on Taguchi's L9 orthogonal array are performed. The machining parameters are spindle speed, feed and depth of cut and the output responses are machining time and amplitude of vibration. The prediction models are developed using ANOVA. To find the best value of the regression model, a real-time coded genetic algorithm (GA) using turbo C++ and MATLAB tool box GA are used. The result indicated that predicted models are significant and the real-time coded GA produced best value.
