The Glass fiber reinforced plastics (GFRP) are highly promising materials for the applications inaeronautical and aerospace industries. Machining of these composites, especially drilling is very important operationwhich is to be carried out. During drilling of GFRP and CFRP delamination is a major concern, which reduces thestructural integrity of the material. The present work is focuses on the analysis of delamination behavior of thecomposites when drilled and methods available to reduce the delamination. Remarkable work has been carried out bydifferent researchers in this area where few have suggested controlling the cutting parameters like cutting speed, feedand depth of cut others have emphasis on thrust force and torque. Some have investigated that tool materials andgeometry can make difference. Even the Artificial Neural Network (ANN) is also suggested to predict the delamination.Traditional and non-traditional drilling processes are feasible for making fine holes for composite materials by carefullyselected tool, method and operating conditions.in this experiment work three different tools with different geometry liketwist drill, step drill and multifaceted drill are used and at the same time feed rate and speed are also taken as variablesand optimization of cutting parameters done.
