Abstract

In this paper, the effects of cutting tool coating material and cutting speed on cutting forces and surface roughness were investigated on a Taguchi experimental design by turning Hastelloy X and Inconel 625. Main cutting force, Fz is considered to be cutting force as a criterion. 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 the results of analysis of variance (ANOVA) and signal-to–noise (S/N) ratio, effects of parameters of both average surface roughness and cutting forces were statistically investigated. It has seen that while feed rate and cutting speed has a higher effect on cutting force in Hastelloy X, the cutting tool and cutting speed has a higher effect on cutting force in Inconel 625 while the depth of cut and feed rate has a higher effect on average surface roughness on Hastelloy X, cutting speed and cutting tool has a higher effect on average surface roughness in Inconel 625.
