... in the drilling of CFRP/Ti stacks include rapid tool wear and poor hole quality. Typically, the surface quality of the holes in the drilling of CFRP/Ti stack is poor due to delamination, the progression of hole diameter in CFRP and burr formation in Ti. Moreover, the flank wear on the tool also influences...
