INVESTIGATION ON TURNING PARAMETERS ON MACHINING TIME AND VIBRATION OF CARBON FIBER REINFORCED LAMINATES ABSTRACT: This work proposes the investigation of machining time and vibration characteristics of machining differently oriented unidirectional Carbon Fiber Reinforced Polymer (CFRP). The carbon fibers are oriented at 0, 45, 90 degrees during stacking process of laminate. The turning experiments are carried out in Siemens-CNC Lathe to investigate best operating conditions. There are 9 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 predication 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. KEYWORDS: Turning, Genetic Algorithm, CFRP, Orientation, Hand-lay up Process. 1.0 INTRODUCTION : Composites are able to meet up diverse design requirements with considerable weight savings as well as elevated strength-to-weight ratio as compared to conventional materials. There are various types of composites such as Metal Matrix Composites (MMC), Particulate Composite (PC) and Fiber Reinforced Polymer composites (FRP). Among these composites, Carbon Fiber Reinforced Composites are widely
