摘要：Carbon Fiber Reinforced Plastics (CFRP) is a kind of typical difficull-to-machine material which are prone to disfigurements such as burrs, delamination and avulsion while drilling. Focusing on these problems, the authors conducted experiment investigations on Carbon/Epoxy composites (a kind of CFRP). Drilling characteristics of diamond electroplated bit was studied by analyzing its drilling force, drilling quality etc., and the results were compared with those of carbide twist drill. The conclusions are as follows;compared with carbide twist drill bit , diamond electroplated drill bit is more suitable for drilling CFRP, and with lower drilling force, better drilling quality; High speed drilling is favorable for minimizing the drilling disfigurements, and the axial force decreases with the speed increasing,and increases with larger bit diameter; Finally, the drilling force empirical formula of diamond electroplated drill was gained by the method of multiple linear regression.
