Abstract: Cubic boron nitride ( CBN) is the second hardest material in the material. Diamond is the only hardest material & its natural material. CBN is actually a powder which is coated on the caeamics/ carbide inserts, in that the binder materials are titanium, so the there is huge area to work on the tool life of CBN inserts, because it is costlier than tungsten carbide & other insert materials. The hard-turning process is steadily finding its place in modern manufacturing technology and with advance cutting tool materials it can be applied as another machining process to turning providing a more economical way to finish hard surfaces. The main concerns of hard turning are tooling cost and the effect of process on machining characteristics. The poor selection of this parameters may cause excessive tool wear and increased surface roughness. Hence there is a need to find the right parameters to achieve the right dimensional accuracy, good surface and maximum material removal rate. This paper reviews the effects of various process parameters such as cutting speed, depth of cut and feed rate on the response parameters such as surface roughness, material removal rate and chip reduction coefficient. Through this study main cutting parameters which affect the turning operation are discussed.
