Abstract: Turning operation is one of the most basic machining processes. That is, the part is rotated while a single point cutting tool is moved parallel to the axis of rotation. Hard turning is becoming more popular for machining hardened steels as it has several benefits over grinding. The hard Turning process is defined as machining metals with the hardness greater than 45 HRC. CNMG 120408 is the dominant tool material for hard turning applications due to its high hardness, high wear resistance, and high thermal stability. The temperature generated in hard turning is Substantially higher when compared to conventional machining as the cutting speeds employed in hard turning are higher and dry cutting environment is usually employed.[1] Hard turning is a high-speed machining phenomenon with surface speeds going normally as high as 250 m/min, sometimes even more than this. So the machine tool capabilities should include high machine tool rigidity, high surface speed, and constant surface speed for a profile to be finished and high accuracy with a required surface finish.[2].
