In today’s scenario, composite like Carbon Fiber Reinforced Polymer (CFRP) is a standout and the most alluring and profitable material among all the designing materials. The reason for using these composite laminates is their superior properties and their influential application in aerospace industries, aircraft structural components, and others. The present learning about drilling of CFRP composites is in a moving stage for its ideal usage in different fields of uses despite being composite overlays are viewed as difficult for machine materials. Drilling process is highly depended on the drilling parameters (i.e. Feed, Speed). This becomes more important when a new product design , shape and hole dimension is critical inwhich high surface finish, accuracy of dimensional tolerances and high material removal rate are required. Therefore, the application using Ultrasonic and Non Ultrasonic is proposed to get the optimization of machining parameters in improving the product quality, as well as its productivity. Effects of input variable of drilling process (Spindle speed, feedrate) using Ultrasonic and Non Ultrasonic on the machining output; entrance and exit hole accuracy also surface roughness were studied. The optimum values of machining parameters can be obtained is Spindle Speed = 2500 rpm , Feed rate = 0.09 mm/tooth and Ultrasonic Assisted Drilling.
