PROCESS PARAMETER OPTIMISATION IN THE DRILLING OPERATION FOR COMPOSITE MATERIALS: An Experimental Investigation

Abstract

This research will investigate methods to improve the surface finish quality of GFRP (glass fibre 
reinforced polymer) composites work pieces using 8mm, 10mm, and 12mm diameter HSS (M2) 
drills with spindle speeds of 1200, 1000, and 800 rpm with feeds of 30, 40, and 50 mm/min. 
Cutting speed, feed, and depth of cut are three of the most critical machinability factors, and the 
Taguchi approach is a useful tool for examining the influence of process parameters and 
identifying the link between surface finish and these factors. There is a high degree of 
concordance between the verified model equations and the experimental data.
