Optimization of the Process Parameter in Drilling of GFRP using HSS Drill

Fabrication and assembly of parts requires drill holes. The importance of better productivity of the Air craft parts while assembling of polymer composite to avoid the rejection process in drilling operation. The drilling operation of machining process is very important in production of aircraft components due to drilling operation 60% of rejection due to delamination. To minimize the rejection of components the selection of process parameters are required. Designs of experiments were conducted using milling machine and modelling analysis used by regression model and Taguchi technique. From the experimental results, feed rate is the most important parameter for delamination.
