Drilling of Carbon Fiber-Reinforced Plastic/Titanium alloy (CFRP/Ti) stacks represents
one of the most widely used machining methods for making holes to fasten assemblies in civil
aircraft. However, poor machinability of CFRP/Ti stacks in combination with the inhomogeneous
behavior of CFRP and Ti alloy face manufacturing and scientific community with a problem of
defining significant factors and conditions for ensuring hole quality in the CFRP/Ti alloy stacks.
Herein, we investigate the effects of drilling parameters on drilling temperature and hole quality
in CFRP/Ti alloy stacks by applying an artificial neuron network (ANN). We varied cutting speed,
feed rate, and time delay factors according to the factorial design L9 Taguchi orthogonal array and
measured the drilling temperature, hole diameter, and out of roundness by using a thermocouple
and coordinate measuring machine methods for ANN analysis. The results show that the drilling
temperature was sensitive to the effect of stack material layer, cutting speed, and time delay factors.
The hole diameter was mainly affected by feed, stack material layer, and time delay, while out of
roundness was influenced by the time delay, stack material layer, and cutting speed. Overall, ANN
can be used for the identification of the drilling parameters–hole quality relationship.
