Abstract
While substantial exploration has been conducted on drilling performances of Glass Fiber-Reinforced Plastic (GFRP) in earlier studies, some key aspects like the influence of process parameters on responses like force, torque, vibration and delamination factor remain to be addressed and viewed holistically. The life of the joint depends on the quality of drilled holes. The paper studies the effect of cutting parameters on responses like cutting force, vibration, delamination factor and surface roughness for different cutting speeds and feed rate during drilling of GFRP material. Two input parameters, viz., speed and feed, are used and the diameter of the drill bit is kept constant for all the cases. From 200 to 300 mm/ min feed rate, acceleration increases gradually, and for higher feed rates, the increment in acceleration is less, increasing the peak acceleration rate higher than 2,500 rpm. Start point of the torque cycle is delayed for a few seconds than the thrust force, and torque decreases with increased cutting speed. Delamination factor increases when the cutting speed increases. From the wavelet analyzer, it is observed that all the coefficients of vibration first decrease, and at the approximate feed rate of 300 mm/min, all the coefficients increase.
Introduction
Application of composite materials is increasing day-by-day because of their excellent properties. They have definite stiffness, good corrosive resistance, low thermal expansion, high strength and high damping. In recent years, Glass Fiber Reinforced Plastic Composite
