Abstract

this paper focuses on the influence of cutting tool edge preparation, cutting speed and feed rate on the tool performance and workpiece's surface integrity in dry turning of Ti-6Al-4V alloy using PCBN inserts. The parameters evaluated are tool life, wear rate, wear mechanisms, surface roughness and subsurface microstructure alterations. The rate of wear growth of the insert was assessed by progressive flank wear using optical microscope by taking photographs after certain length of cut. The wear mechanism at the end of tool life was investigated in detail using scanning electron microscope (SEM) and EDAX analysis. The results show, by increasing the cutting speed and feed rate resulted in tool life reduction. Cutting with honed edge insert at cutting speed of 180 m/min has shown very little wear, even after 20 min of cutting. The honed insert proved less sensitive to increases in feed rate than the chamfered insert. In general the honed insert showed a significant improvement in tool life. All inserts failed due to attrition wear and adhesion. No flank notch wear was observed, but some crater wear was occurred behind the cutting edge. Microstructure alteration was not encountered when machining using the different edge geometry. In these trials the subsurface micro structural deformation caused by machining consists of deformed grain boundaries in the direction of cutting and elongation of grains. Chip smearing and debris on the surface was also found. The hardness in the vicinity of machined surface (at distance >0.15 mm) was lower than the hardness in the deeper machined surface (at distance <0.15 mm). The layer softening was occurred rather than the hard white layer. The machined surface hardness was not affecting by different type of edge geometry.
