Abstract
In this study, were investigated the effects of cutting speed on cutting forces and surface roughness based on Taguchi experimental design. . The effects of machining parameters were investigated using Taguchi L18 orthogonal array. Optimal cutting conditions were determined using the signal-to-noise (S/N) ratio which is calculated for average surface roughness and cutting force according to the "the smaller is better" approach. Using results of analysis of variance (ANOVA) and signal-to–noise (S/N) ratio, effects of parameters on both average surface roughness and cutting forces were statistically investigated. Tree different cutting tools were used in experiments as KYON 4300, KYS 25 and KYS 30. Main cutting force, Fz is considered to be cutting force as a criterion. In the experiments, depending on the tool material, lowest main cutting force 592 N at 260 m/min and lowest average surface roughness (0.424 μm) at 230 m/min with KYS25 ceramic tool was found. While cutting speed and feed rate has higher effect on the cutting force, the feed rate and cutting speed has seen higher effect on average surface roughness. In the cutting force and surface roughness turning tests, the KYON 4300 cutting tool has seen better performance than the other cutting tools.
