摘要

This study investigated sustainable machining of AZ91D magnesium alloy under dry, MQL, and RHVT conditions using RSM and ANOVA. MQL and RHVT improved cooling and surface quality, with machining environment and cutting speed identified as the most influential factors. ANOVA results showed environmental conditions significantly reduced surface roughness, with temperature contributing 28% to roughness and 42.19% to temperature variation. Cutting speed was the next dominant factor, accounting for 25.40% of roughness and 27.96% of temperature. Feed rate contributed 24.89% and 13.34%, while depth of cut had minimal influence overall.
