摘要: Abstract Drilling is a metal removal process and important for the final fabrication stage prior to application. This paper discusses influence of cutting parameters on drilling characteristics hybrid matrix composites (MMCs)—Al2219/15SiCp Al2219/15SiCp–3Gr. The are fabricated using stir casting method. Taguchi design experiments analysis variance (ANOVA) employed analyze these composites. were conducted study effect spindle speed feed rate force, surface finish burr height solid carbide multifacet drills 5 mm diameter. results reveal that dependent variables greatly influenced by rather than both ceramic–graphite reinforced composite has better machinibility those with SiCp
