Experimental Study of Drilling Carbon Fiber-Reinforced Plastic (CFRP) with Candlestick Drill Using the Taguchi Method

Abstract:

In this paper, an approach is developed on Taguchi method to optimize the drilling parameters in drilling carbon fiber-reinforced plastic (CFRP) by the candlestick drill bits. The experimental results indicate that the feed rate (f) and the drill diameter (d) are the most important factors and the spindle speed (S) is insignificant in drilling CFRP laminates. The optimal drilling performance for the thrust force was obtained at 0.01 mm/rev feed rate, 800 rpm speed spindle and 6 mm drill diameter settings. The best combination to attain smaller delamination factor was 0.01 mm/rev feed rate, 800 rpm speed spindle and 10 mm drill diameter.
