Paper Title:
Study on the Machinability Characteristics of Superalloy K424 during High Speed Turning
  Abstract

The present paper is an attempt of an experimental investigation on the machinability of superalloy, K424 during high speed turning using different ceramic inserts under different cutting speed and cooling/lubricating condition. The effect of machining parameters on the tool wear was examined through SEM micrographs.The experimental results show that, round Al2O3+SiCW KY4300R ceramic insert shows the best cutting performance in cutting the superalloy K424 , and it should be used in rather higher speed. Cold nitrogen gas is not recommended when machining nickel-based alloy with ceramic tools. SEM and EDS analysis shows that the ceramic tool was severely controlled by tool nose and depth-of-cut notch wear, followed by flaking and chipping.
