Abstract
The accuracy of predicting drilling temperature in CFRP drilling is helpful to process optimization and defect suppression. The previous models for predicting CFRP drilling temperature are few and need to be more systematic. Combined with theoretical modeling and experimental verification, a comprehensive theoretical model is developed to predict the temperature distribution during the drilling process of unidirectional CFRP (UD-CFRP), which considers the synergy of the chisel edge and main cutting edge of the drill bit, as well as the influence of fiber orientation angle (FOA). Results show that the predicted peak temperatures parallel to and vertical to the fiber direction present tiny errors of 2.26–5.27% and 4.44–7.55% respectively, indicating that the model is reliable. At 1 mm from the hole wall of UD-CFRP, the peak temperature decreases with the increase of FOA. The drilling temperature decreases with the increase of feed rate and increases with the increase of spindle speed. At the outlet layer of UD-CFRP, the contribution of spindle speed to temperature rise is more significant than the feed rate.
