Modeling and optimizing the delamination factor in Agave americana L. biowaste fiber-reinforced biocomposite drilling: a study using RSM and ANN methods

Abstract This study investigates how key drilling parameters—feed rate (f), spindle speed (N), and drill diameter (d)—affect the delamination factor (Fd) during the machining of the Flower stalk of Agave americana (FSAa) fiber-reinforced biocomposites, using High-Speed Steel (HSS) and High-Speed Steel Coated with Titanium (HSS-TiN) tools. The experimental results show that increasing f and d leads to a decrease in Fd, reaching a minimum of 1.074 with the HSS tool compared to 1.020 with the HSS-TiN (N = 800 rpm,
