Abstract
This study used an experimental method with variations in cutting angle, cutting depth, and machine rotation speed to measure their effects on cutting tool wear in the ST90 steel turning process. The ANOVA used to determine the main factors and interactions between factors that affect machining results. From the results of cutting angle factor A, cutting depth factor B, and rotation speed factor C, it was found that the single factors A, B, and C did not have a significant effect on the test results. The Fcount values obtained were A=0.1122, B=0.0648, and C=0.0959, all of which were smaller than the Ftable values of 3.26, 18.51, and 19.00, respectively. The AB interaction resulted in Fcount = 28.29 > Ftable = 6.94, the AC interaction resulted in Fcount = 421.77 > Ftable = 6.39, and the BC interaction resulted in Fcount = 817.85 > Ftable = 3.26. Thus, the interaction between factors showed a significant effect. This confirms that the combination of factors is more decisive in determining the results than the influence of individual factors. Meanwhile, the interaction of the three factors ABC has no significant effect because Fcount = 0.2073 < Ftabel= 2.63
