Effect of Milling Process Parameters on the Multiple Performance Characteristics

Abstract

In the present work an investigation has been made to explore the effect of speed, feed and
depth of cut on the multiple responses of material removal rate (MRR) and surface roughness
(Ra). A series of experiments were carried out on CNC milling machine using a carbide end
mill cutter. Wrought alloy AA8011 has been taken as the work piece for the experiments and
L27 orthogonal array (OA) has been followed. The effect of process parameters on the
performance characteristics was analyzed using single objective taguchi method and
ANOVA. The optimal designs for the performance characteristics were predicted using the
estimated averages of the responses and they are found to be more accurate and adequate.
