Abstract

In this study, flank wear on CBN and PCBN tools due to cutting forces were studied. Turning tests were carried using cutting speeds of 100, 125, 150, 175 and 200 m/min with feed rates of 0.10, 0.20 and 0.30 mm /rev and constant depth of cut of 1.00 mm. The performances of cutting tools were evaluated based on the flank wear and cutting forces. The wears were measured by scanning electron microscope and the cutting forces measured by a dynamometer. There is clear relationship between flank wear and cutting forces while turning hard martensitic stainless steel by CBN and PCBN tools. Lower cutting forces leads to low flank wear and low cutting force provides good dimensional accuracy of the work material including low surface roughness. Flank wear formation was mostly caused by abrasion and less by adhesion. The built up edge formed reduced the cutting forces. High cutting forces are identified and this may be due to heat and flank wear combinations. Flank and crater wear on the rake face and hard metal deposition due to diffusion of metals on the cutting tool surface are the damages occurred during process.
