Abstract: quotComposite materials possess several desirable properties when compared against newlineconventional metal such as, their high specific strength and specific modulus, their variable newlinedirectional strength properties and their better fatigue strength. The fiber reinforced plastics newline(FRP) are highly promising materials for the applications in aeronautical and aerospace newlineindustries. Composites are being abrasive, the tool wear is high and hence the machining newlineparameters are to be carefully selected while machining GFRP composite materials. newlineMachining of these composites, especially drilling is very important operation which newlineis to be carried out for assembly of composite parts. During drilling of GFRP and CFRP newlinedelamination is a major concern, which reduces the structural integrity of the material. The newlinepresent work is critical review which focuses on the analysis of delamination behaviour of the newlinecomposites when drilled and methods available to reduce the delamination. Remarkable work newlinehas been carried out by different researchers in this area where few have suggested newlinecontrolling the cutting parameters like cutting speed, feed and depth of cut others have newlineemphasis on thrust force and torque. In this experiment work GFRP laminate with specific newlineproperties is manufactured and drilled with three drills having different point angles of 118 degree, newline130 degree, 140 degree. Speed, Feed rate and Point angle are taken as variables and drilled holes are newlinemeasured for delamination. Effect of cutting parameters and tool geometry (point angle) on newlinedelamination are studied. ANFIS (Adaptive Neuro Fuzzy Inference System) based newlinemathematical model is developed in MATLAB to control the delamination. Based on the newlineabove ANFIS model one can select best cutting parameters to minimise delamination.quot newline newline
