摘要

This paper presents a study on the machinability behavior of biodegradable magnesium alloys (Mg6Zn1Mn, Mg10Gd3Y, Mg7Y) aimed at understanding their suitability for conversion into final products. The study evaluates the manufacturability of these alloys through turning operations, analyzing various responses. Taguchi and ANOVA analyses were conducted to determine optimal machining conditions. Results indicate that all three alloys can be effectively machined using a lathe machine, with outcomes optimized through parameter selection, but, notably, for Mg6Zn1Mn alloy, optimal turning parameters included a spindle speed of 1180 rpm, feed rate of 0.05 mm/rev, depth of cut of 0.8 mm, and tool material TC, resulting in minimized surface roughness. Moreover, the percentage contribution of each machining parameter on desired outcomes was determined, with feed rate found to have the highest contribution (39.26%) to surface roughness for Mg6Zn1Mn. This holistic approach, considering multiple responses such as material removal rate, power consumption, surface roughness, and forces, offers insights applicable to final product development. The statistical analysis conducted in this study can be extended to similar investigations for other materials intended for diverse applications.
