    Abstract

    This paper presents the investigation on the effect of edge geometry of PVD-TiN coated carbide inserts on the cutting performance and wear characteristics during face milling of titanium alloy, Ti-6246. Two similar PVD-TiN coated inserts with different edge geometry were tested at various cutting speeds with a feed of 0.1 mm/tooth. Results showed that edge geometry had a significant effect and sharp insert was observed to outperform chamfered (T-land) insert at all conditions. Excessive chipping and flaking at the cutting edge were the dominant failure modes on both tools under most conditions. In addition to adhesion, attrition and diffusion wear mechanisms, thermal cracks and plastic deformation were also observed on both tools.
