Research on Performance of Drilling Carbon Fiber Reinforced Plastics with Diamond Coated Special Drill

Abstract:

The carbide cemented special drills with TiAlCrN/TiSiN coating and diamond coating respectively were selected to drilling on carbon fiber reinforced plastics (CFRP) for a contrast test in this paper. The drilling force , drilling exit surface quality and tool wear were analyzed separately to research the performance characteristics of the two kinds of special drills with different coating. The results show that: under the same cutting conditions, the thrust force of the special drill with diamond coating is smaller than that of the TiAlCrN/TiSiN coating, and the tool life is extended by 2 times at the same time. The diamond coated special drill can improve the drilling surface quality, it is more suitable for drilling CFRP.
