With the advancement in the field of materials, the material removal processes with high surface accuracy have also become more and more challenging. This paper reports use of PVD-coated tungsten carbide tool CNC lathe machine under wet condition using cutting oil for high-speed turning of Inconel 718. Effect of process parameter—speed, feed, and depth of cut on response parameter change in surface roughness and tool wear—has been studied on INCONEL-718 using ANOVA. Also, the effect of given parameters on the tool wear and chip formation was investigating through SEM micrographs. It has been found that speed and feed have significant effect on percentage change in surface roughness. It is also cleared that at low depth of cut, low speed and moderate feed, the chip is a continuous type whereas at high speed, low feed and high depth of cut, formation of chip becomes sawtooth type.
