Abstract
The thermal conductivity of carbon fiber reinforced polymer(CFRP) and titanium alloy is lower which caused the increasing of drilling temperature and larger tool wear resistance. The low temperature air is aided for the drilling of laminated stack board of CFRP/Ti with double apex angles carbide drill at different feed rate. The drilling force and the quality of hole are analyzed. The results showed that the low temperature air can reduce the tool wear and the thrust force effectively.
