"Optimization of Process Parameters for Surface Roughness and Tool Life in Face Milling using The Taguchi Analysis", Materiali in Tehnologije 49 (1) 139-147, 2015.http://mit.imt.si/Revija/izvodi/mit151/sarikaya.pdfhttps://hdl.handle.net/11486/1031In this study, the Taguchi method, which is a powerful tool to design quality optimization, is used to find the optimum surface roughness and tool life in milling operations. An orthogonal array, a signal-to-noise (S/N) ratio, and an analysis of variance (ANOVA) are employed to investigate the tool life and the surface-roughness characteristics of AISI D3 steel. Accordingly, the lowest surface roughness and the highest tool life were estimated to be 0.436 ?m and 434.1 s, respectively and, finally, the Taguchi method allowed the optimization of the system for the verification of the tests. Further, ANOVA analysis was revealed that the number of cutter insert was the most important parameter influencing the surface roughness with a 75.27 %, and cutting speed was the most important parameter influencing the tool life with a 95 %.V tej {tudiji je bila uporabljena Taguchijeva metoda kot mo~no orodje za ugotavljanje razmer za doseganje optimalne hrapavosti in trajnostne dobe orodja pri rezkanju. Ortogonalna matrika, signal hrupa (S/N) in analiza variance (ANOVA) so bili uporabljeni za preiskavo zdr`ljivosti orodja in hrapavosti povr{ine jekla AISI D3. Na podlagi rezultatov je bila ocenjena najmanj{a hrapavost povr{ine 0,436 ?m in najve~ja zdr`ljivost orodja 434,1 s, Taguchijeva metoda pa je omogo~ila optimizacijo sistema pri verifikaciji preizkusov. Nadalje je ANOVA analiza odkrila, da je {tevilo rezalnih vlo`kov najbolj pomemben parameter, ki s 75,27 % vpliva na hrapavost povr{ine, hitrost rezanja pa je najpomembnej{i parameter, ki s 95 % vpliva na `ivljenjsko dobo orodja.enMaterial machinabilityFace millingTaguchi methodOptimizationExperimental designObdelovalnost materialaTaguchijeva metodaOptimizacijaArticle
