摘要

Carbon Fiber Reinforced Plastics ( CFRP) is a typical difficult to machine material which is prone to disfigurements such as burrs, avulsion and delamination, and rapid tool wear, high processing cost. Aimed at the defect of Carbide Twist Drillbit (CTD) when drilling on CFRP, a new type of drillbit, which is called Drilling-Reaming Composite Drillbit (DRCD), was designed and used to drill holes on a plate of CFRP. Through experimental study and analysis, and compared with CTD, we found that drilling with DRCD have higher dimension accuracy and better surface quality when drilling on CFRP, and it has minor wear on its cutting edges and its tool life at least ten times that of CTD. So we draw conclusion that DRCD with high wear resistance and good stability is more suitable for drilling CFRP.
