The glass fiber reinforced composites are widely used in engineering applications such as aircraft, automotive, and manufacture of spaceships and sea vehicles' industries due to their significant advantages compared to the other materials. This type of composite provides high specific strength/stiffness, superior corrosion resistance, lightweight construction, low thermal conductivity, high fatigue strength, ability to char, and resistance to chemical and microbiological attacks. Many researchers in the previous years have attempted to study the machining of glass fiber reinforced composite materials to identifying the effect of various process parameters on the quality of machining structures. Drilling is an important process for making and assembling components made from Glass Fiber Reinforced Plastic (GFRP). Various processes like conventional drilling, vibration-assisted drilling, and ultrasonic-assisted drilling have been attempted to maintain the integrity of the material and obtain the necessary accuracy in the drilling of GFRP. In this research, an attempt has been conducted to review many of the previous researches on the drilling of GFRP. The process parameters such as the spindle speed, the feed rate, the depth of cut, the volume fraction ratios, the tool material, and the tool geometry and their influence on the multi responses as, the hole surface roughness, the delamination in the hole, the thrust force and the torque, all of this are studied and analyzed. Also, the different optimization techniques and methods for optimizing the mentioned parameters are studied and analyzed.
