With the use of 8mm, 10mm, and 12mm diameter HSS (M2) drills, spindle speeds of 1200, 1000, and 800 rpm, and feeds of 30, 40, and 50 mm/min, this study will perform tests to enhance the surface finish quality of GFRP (glass fibre reinforced polymer) composites work pieces. The Taguchi technique is a powerful tool for studying the impact of process parameters and finding the relationship between surface finish—the most important machinability factor— and cutting speed, feed, and depth of cut. The experimental results and the validated model equations are found to agree quite well.
