【 摘 要 】

In recent years, environmental conscious lubricating system is highly popular for hard turning applications due to lots of limitation and complexity noticed in wet and dry cutting environments. Present work focused on performance analysis of multilayer coated carbide tool on heat treated AISI D2 steel (55 ± 1 HRC) in dry as well as in spray impingement cooling surroundings. Chip-tool interface cutting temperature (T), average surface roughness (Ra) and chip morphology have been considered as the performance measuring parameters. Machining performance under spray cooling environment is improved compare to dry. Cutting temperature at chip-tool interface increases with rise in cutting speed and depth of cut whereas surface roughness increases with cutting feed. Continuous and discontinuous chips with saw tooth have been observed in both cutting environments.
