study presents optimization of process parameters using Taguchi design method
in finish turning of austempered ductile iron. An orthogonal array of L18
was used; ANOVA was performed to identify significant factors affecting surface
roughness (Ra) and primary cutting force (Fc). Optimum
processes parameter combination was acquired by using analysis of
signal-to-noise (S/N) ratio. For Ra and Fc
values, prediction error was found to be within the confidence limit at 95%
confidence level
