The drilling experiment was carried out under dry condition follows established set up using 3 axis Deckle FP3A CNC machine (Heidenhain TNC 355 system) and Aitefasi drill bits (Aitefasi Tools Co., Ltd, China, diameter = 6mm, helix angle = 30°, point angle = 104°). A full factorial experiment was performed using four levels of spindle speeds (S) and five levels of feed rates (𝐹𝐹 𝑓𝑓 ), see Table . The drilling parameters are selected in accordance with the literature and tool suppliers' recommendation. Under each set of drilling parameters, three holes were made to ensure repeatability. The thrust force was measured using a dynamometer (Kistler 9272) coupled with charge amplifier (5070A) and data acquisition unit (5697). The maximum hole wall temperature was captured using a 125 Hz FLIR A6751 thermal camera with the holes drilled 0.5 mm from the composite edge following previous study , see Fig. (a).
