Abstract
In this work, we focus on evaluating the mechanical performance and effects of the drilling parameters as a function of cutting process such as spindle speed (355, 710 and 1400 rev/min), feed rate (50, 108 and 190 mm/min) and the tool diameter (5, 7 and 10 mm) on eventually delamination factors in drilling short jute fibre-reinforced polyester biocomposites (JFRBCs). The work was carried out using Brad & Spur (HSS) drill. The experiment design was established by application of the analysis of variance (ANOVA). The goodness-of-fit for F-d delamination factor was detected between the predicted and experimental results with a high coefficient of R-2 of 0.9156 for jute fibre at 5 mm of length reinforced with polyester matrix (J05). The obtained optimum conditions for F-d factor were a feed rate of 50 mm/min, a spindle speed of 1069.41 to 1150.97 rev/min, and a drill diameter of 5 mm.
