CFRP (Carbon Fiber Reinforced Plastic) has higher specific strength, modulus of elasticity and so on. CFRP is, however, well known as difficult-to-cut material, which has very strong physical and mechanical characteristics. High-precision and high-efficiency cutting technique of CFRP is one of the most important cutting operations in industrial factory of aviation, automobile and so on. In this research the experiments are carried out making drilled holes on the laminated plates of CFRP with using two different shaped ball-nose end mills. It is found that the machining accuracy is affected by the tool shape of cutting edges on the cutting point.
