Glass fiber reinforced plastics are finding increased applications in various engineering fields such as aerospace, automotive, electronics and other industries. Drilling is one of the most frequently practiced machining processes in industries owing to the need for component assembly in mechanical structures. In this work, experiments were conducted using 8 Facet Solid Carbide drills based on L27 Orthogonal Array. The process parameters investigated are spindle speed, feed rate and drill diameter. Fuzzy rule based model is developed to predict thrust force and torque in drilling of GFRP composites. The results indicated that the model can be effectively used for predicting the response variable by means of which delamination can be controlled.
