Abstract

The objective of this study is to identify optimum machining parameters on surface quality of sculptured parts. The effect of various machining process parameters such as machining strategy, feed, depth of cut and spindle speed on surface roughness during three-axis end milling of sculptured parts have been studied by performing a number of experiments constructed according to standard Taguchi’s L9 orthogonal array design matrix. Grey relational analysis method was used to find the optimal machining process parameters and analysis of variance was carried out to find the significance and contribution of each machining parameter on performance characteristics. Finally, confirmation test was conducted to indicate the effectiveness of this proposed method.
