摘要：

Low productivity due to rapid tool wear is the main reason for considering Ti-alloys as difficult to machine. Unlike in machining steels, crater wear in machining of Ti-alloys is equally significant as flank wear. In the present investigation, the maximum crater depth and flank wear have been measured while turning Ti-6Al-4V alloy with uncoated tungsten carbide inserts under dry, wet and cryogenic cooling environments. Compared to dry and wet machining environments, cryogenic cooling in the form of liquid nitrogen (LN2) jets reduces the crater wear. Significant improvement in tool life also has been obtained under cryogenic cooling. However, SEM-EDAX analysis of the worn tool crater shows presence of Ti under all environments though in varying degrees.
