Parametric optimisation of multi response drilling process using Grey based Taguchi method

Abstract

In the present work, optimization technique such as Grey based Taguchi methods have been used to predict surface roughness of drilled holes and drill flank wear into a single characteristic response. Experiments have been conducted in a radial drilling machine with five input parameters using L27 orthogonal array. Minimum flank wear and average surface roughness is the required objective parameter. It has been observed that combined response affected by almost all input parameters, but drill diameter is most significant and feed is least significant input parameter influencing the combined responses
