Summary:In today’s scenario, Glass Fibre Reinforced Polymer Composites are one of the most fascinating and lucrative among the various materials. The superior properties and influential applications of composites in automobiles, medical applications, MEMS, circuit boards have made them outstanding. For assembly of components, the most common operation is riveting for which good quality hole is required. Drilling is the most common operation for producing holes. In this perception, holes of 1.0 mm diameter have been drilled on composite laminate with the help of a conventional lathe machine and machining parameters such as speed, feed and lubrication are optimized. Taguchi’s L9 Orthogonal Array has been designed with three control factors with three levels i.e., speed (433 rpm, 595 rpm, 750 rpm), feed (0.01 mm/rev, 0.02 mm/rev and 0.03 mm/rev), lubricant (dry condition, water lubrication and soluble oil lubrication). ANOVA has been conducted to find out the most influencing parameter. From the results it has been concluded that feed has the highest contribution for MRR, lubrication has highest contribution for Delamination and speed has highest contribution for circularity error.
