Effect of Milling Process Parameters on the Multiple Performance Characteristics

Ch. Maheswara Rao, R. Vara Prasad


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.
