Aim:-The Present study is focused on the comparison of performances of Titanium carbide(TIC) and Uncoated carbide tool inserts with CNC turning of HCHC D2 Steel for minimizing surface roughness and maximizing material removal rate. Materials And Methods:-Machining of HCHC D2 steel material was compared with Titanium carbide(TIC) and Uncoated carbide tool inserts. It was divided into two groups of 27 samples each. The samples were machined with two different tool inserts one was control group and other was experimental group. Results:-Surface roughness was decreased and material removal rate was increased when machining was done with TIC carbide compared to HSS tool insert (P=0.028).Conclusions: It is concluded that the surface roughness was decreased and material removal rate was increased when TIC carbide tool insert was used for machining.
