Turning hardened tool steel using ceramic cutting tool, has certain advantages over the traditional turning/hardening/cylindrical grinding practice in terms of increased productivity and reduced power consumption. The hard turning is generally performed without a coolant (additional environmental advantage).An experimental investigation was carried out using ceramic cutting tools, composed approximately with (70%) of Al2O3 and (30%) of TiC, in surface finish operations on cold work tool steel D2 (AISI) heat treated to a hardness of 60 HRC.A plan of experiments, based on orthogonal arrays, was made in turning with prefixed cutting parameters in tool steel workpieces. A combined technique using orthogonal array and analysis of variance (ANOVA) was employed to investigate the machinability of cold work tool steel. The results of the tests shows that with a appropriate cutting parameters choice is possible to obtain a surface roughness (Ra < 0.8 μm) that allows to eliminate cylindrical grinding operations.
