Comparative Study of Cryogenically Treatment single cutting tool - Softcover

Inhaltsangabe

Cryogenic treatment claimed to improve wear resistance of steels and has been implemented in cutting tools since long. Although it has been confirmed that cryogenic treatment can improve the service life of tools the underlying mechanisms of tool face temperature, cutting forces remains unclear. The literature published in this regards reports that cryogenic treatment facilitates the formation of carbon clustering and increases the carbide density in the subsequent heat treatment, which further improves the wear resistance of steels. In the present work an effort has been made for tool life enhancement of single point cutting tool with cryogenic treatment. Experimental study has been conducted on medium carbon steel (AISI1018) work material, with HSS (M42) single point cutting tool (cryogenic and non-cryogenic treated) in dry turning operation at different feed rate and length of cut. The results of study highlights that while turning with HSS cryo- treated tool the tool face temperature, the cutting forces are less than as compared to conventional treated tool bit and also shows improvement in surface finishing. The optimize results have been obtained at the feed rate of 0.05mm/rev in terms of lower cutting forces, tool face temperature (reduced by 9.23%) and surface roughness (reduced by 6.72%) when the cutting tool is subjected to cryo-treatment.
