Experiments were conducted on the basis of Taguchi's L16 orthogonal array (OA) at different levels of the factors relating to the aging process, the cutting speed, the feed rate, the axial depth of a cut and the radial depth of a cut; then they were evaluated through the signal/noise ratio (S/N), ANOVA and the main effects' graphic. Accordingly, the lowest surface roughness was estimated to be 0.436 m and, finally, Taguchi's method allowed the optimization of the system for the verification of the testsRaziskan je vpliv multiprocesnih parametrov na hrapavost površine aluminijeve zlitine AA6013, obdelane s karbidnim rezkarjem in z načrtovanjem preizkusov po Taguchijevi metodi. Preizkusi so bili opravljeni na podlagi Taguchijeve ortogonalne porazdelitve L16 po različnem staranju zlitine, pri različnih hitrostih rezkanja, podajanja, aksialne in radialne globine rezov in ocenjeni na podlagi razmerja signal/hrup (S/N), ANOVE in grafičnih zapisov glavnih vplivov. Na podagi rezultatov je bila ocenjena kot najmanjša hrapavost površine 0,436 m, s Taguchijevo metodo pa so bili verificirani preizkusi in optimiziran sistemTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
