In recent years, sintered tungsten carbide has been used to manufacture molds or steel rolling shafts. The Cubic Boron Nitride is a super hard material used to machine hard-to-cut substances as tungsten carbide. The aim of the research is to decide the optimal slitting conditions in the hard turning tungsten carbide with both the reactions (the quality surface and the flank wear). This study has designed an RSM model with trial points in the center of the face. Analysis of variance performed with the quality surface along with flank wear showed that the experimental data set was statistically significant. The composite desirability for the quality surface along with flank wear was determined. The outcomes of optimizing multi responses using the composite desirability showed that the composite desirability obtain the maximum value 0.9487 with depth of cut 0.1 mm, cutting speed 36 m/min and feed rate 0.11 mm/rev. Hence, the contour plot for the composite desirability with the feed rate 0.11 mm/rev indicated that the composite desirability is greater than 0.9 with the cutting speed less 50 m/min and the cutting depth less 0.2 mm.
