摘要

The AZ91 magnesium alloy offers exceptional properties, making it a key material in engineering applications. Present study optimizing the dry drilling process parameters for AZ91/10 wt% SiC nanocomposite. Utilizing an MTAB-XLMILL vertical drilling featured with computer numerical controller (CNC) and CBN-coated drill bits, we conducted dry drilling experiments with drills (M6, M8, M10, and M12), spindle speeds of 250–1000 rpm, and feed rates of 5–20 mm/min, with a 10mm depth of cut. The results were analyzed to identify the most efficient drilling parameters using the ANOVA L-16 approach and the general linear model (GLM). Our findings indicate that maintaining 250–500 rpm, coupled with a feed rate of 20 mm/min for a 10–12 mm drill diameter, yielded minimal machining time, reduced surface roughness, and an enhanced metal removal rate. This study underscores the significance of feed rate and drill diameter in optimizing the drilling process for AZ91/10 wt% SiC nanocomposite, offering valuable insights for industrial applications.
