Determination of optimal cutting conditions in finish turning of austempered ductile iron using Taguchi design method

摘要

This study presents optimization of process parameters using Taguchi design method in finish turning of austempered ductile iron. An orthogonal array of L_(18) was used; ANOVA was performed to identify significant factors affecting surface roughness (R_a) and primary cutting force (F_c). Optimum processes parameter combination was acquired by using analysis of signal-to-noise (S/N) ratio. For R_a and F_c values, prediction error was found to be within the confidence limit at 95% confidence level.
