Abstract
CFRP (Carbon Fiber Reinforced Plastic) has higher specific strength, modulus of elasticity and so on. However, CFRP is well known as difficult-to-cut material which has very strong physical and mechanical characteristics. Drilling technique of CFRP which is one of the most important cutting operations is currently carried out in industrial factories. In this research, it is considered that the effect of drill tools which have different shapes on the machining accuracy of drilling holes on CFRP plates. From our experiments, cemented-carbide ball end mill is suitable for the drilling of CFRP plates. In case of ball end mill in the drilling process of CFRP plates, the thrust forces is below 100 N and drilled holes have good quality without large burrs and chippings until 80 drilling processes.
