Abstract—Now-a-days the application of Glass Fiber reinforced polymer (GFRP) composite materials has increased a lot in the field of engineering. Afterward, the need for better surface finish of GFRP composite materials machining has increased greatly. In this paper a hybrid model of Harmony Search (HS) with Response Surface Methodology (RSM), has been developed for optimizing the surface roughness of three different GFRP composite materials during drilling operation. The machining parameters viz., cutting speed, feed rate, cutting tool point angle and lip clearance angle were optimized with the consideration surface roughness using HS algorithm. In addition, the optimized results using HS algorithm is compared with desirably analysis. Finally, the effect of different machining parameters on surface roughness are also studied.
