The present work is based on turning experiments conducted on a lathe using uncoated tungsten carbide cutting tools for the machining of maraging steel. The L9 orthogonal array based on design of experiments was applied to plan the experiments, by selecting three controlling factors, namely the cutting speed (v), feed (f) and depth of cut (d). The Taguchi analysis was applied to examine how these cutting factors influence the cutting force (Fz). An optimal parameter combination was then obtained using the experimental results. Analysis of variance was also carried out to examine the most significant factors for the Fz in the turning process.
