In this experimen tal work, the effect of various cutting fluid levels and cutting parameters
on surface roughness and tool wear was studied. Taguchi orthogonal array was employed
to minimize the number of experiments. The experimen ts were carried out on mild steel
bar using a TiCN + Al2O3 + TiN coated carbide tool insert in the CNC turning process. The
effect of feed rate was found to be the dominant factor contributing 34.3% to surface roughness of the work-piece. The flow rate of the cutting fluid also showed a significant contribution (33.1%). However, cutting speed and depth of cut showed little contribution to
surface roughness. On the other hand, cutting speed (43.1%) and depth of cut (35.8%) were
the dominant factors influencing tool wear. However, application of cutting fluid (13.7%)
showed a considerable contribution, while the feed rate gave the least contribution to tool
wear. The optimum cutting conditions for desired surface roughness and tool wear were at
a high level of cutting speed, medium level of depth of cut, low level of feed rate and lowflow high-velocity (LFHV) cutting fluid flow from the selected levels.
