 This study examined the effects of various drilling parameters on thrust force, exit burr formation, changes in the microtool, and drilled hole diameters during the microdrilling of an aluminum polyethylene composite panel, LPE. The panel consisted of 3,501 series aluminum skin materials bonded to a polyethylene, PE, core. 5 control parameters were used to design the tests, cutting speed, feed rate, tool diameter, tool point angle, and tool material, LTN or uncoated. The results showed that tool point angle had the greatest positive influence on thrust force at the upper aluminum plate, while cutting speed had the greatest positive influence at the lower aluminum plate. Tool point angle also had the greatest positive influence on burr height at the lower aluminum plate. Additionally, the LTN coating had a positive effect on tool wear and hole diameter deviations, but it adversely affected the burr height.
