description In the recent industry, magnesium alloys are always preferred for low weight but high strength applications. This study investigates the effect of the drilling diameter and cutting speed on the machinability during drilling magnesium alloys. It provides further data and recommendations to aid machinists and engineers in future magnesium applications. Nine sets of experiments were conducted using three drilling diameters (6mm, 8mm and 10mm) and three cutting speeds (60m/min, 90m/min and 120m/min), resulting in a total of 45 holes drilled into 15mm thick magnesium workpieces.
