Abstract

In this research work, an attempt has been made to investigate the effect of liquid nitrogen when it was applied to heat generation zones through holes made in the cutting tool insert during the turning of Aluminium 6061 — T6 alloy with uncoated carbide tool. The cryogenic result of the cutting temperature, cutting force, surface roughness, tool wear and chip form for the modified cutting tool insert have been compared with wet machining. The cutting temperature was reduced by 60 — 74% in cryogenic cooling over wet machining. The cutting force was decreased by   21 — 39% in cryogenic cooling with modified cutting tool insert over wet machining. It was also observed that in the cryogenic cooling method, the surface roughness was reduced to a maximum of 43% and the flank wear was reduced by 38 — 49% over wet machining. Cryogenic cooling enabled a substantial reduction in the geometry of tool wear through the control of tool wear mechanisms. The application of cryogenic cooling was considered to be more effective in chip breaking over wet machining.
