Sažetak
The increase use of glass fibre reinforced polymer (GFRP) composites in recent years has led to an increased demand for machining. Milling of glass fiber reinforced polymer (GFRP) composites becomes essential in order to enhance its surface quality. In this paper, optimization of machining parameters in milling of horizontal axis wind turbine (HAWT) blade wrapped with E-glass fiber reinforced plastics (GFRP) composites with multi-response criteria-based desirability function analysis (DFA). The machining parameters such as spindle speed (A), feed rate (B) and depth of cut (C) are optimized by considering multiple response characteristics namely surface roughness (Ra) and hardness (HB). The desirability at a high of 0,83 provides minimum surface roughness about 2,64 μm 0,7 and maximum hardness about 49,12 BH.
