Investigation on Influence of Cutting Forces In Performance Evaluation of Machining Of Al/Sic Composite (LM-13) Using Cryogenic Liquid Nitrogen as A Coolant

Abstract—This paper reports influence of cutting forces using cryogenic Liquefied Nitrogen
(LN2) lubricant in machining of (LM-13)Aluminum metal matrix composite compare to
conventional coolant. The Silicon Carbide is used as reinforcement material in Aluminum
Silicon alloy (LM-13). The various machining parameters such as machining force, radial
force,feed force, and surface roughness were analysed under conventional and cryogenic
nitrogen cooling environments. The experimental results under liquid nitrogen coolant and
conventional coolant conditions were taken for evaluation. The results showed that cutting
forces and surface roughness values of machined workpiece reduced considerably on applying
of cryogenic LN2 coolant compared to conventional machined environments.
