Abstract

This research work focuses on the experimental investigations conducted using uncoated cBN tool and (AlCrN) PVD Coated cBN tool for turning Inconel 718. Two different sets of experiments – one with uncoated cBN and another with coated cBN inserts were conducted considering three different levels of cutting speeds, feed rates and depth of cuts. The performance of the coated cBN over the uncoated inserts were evaluated and it was found that the AlCrN coated cBN inserts can produce 10-12% drop in the cutting force, 15% reduction in the flank wear and 10% reduction in the surface roughness.
