Experimental Investigation of Cryogenic Cooling by Liquid Nitrogen in the Orthogonal Machining Process

The most emerging needs of the modern metal cutting operation are to increase the material removal rate with better surface finish and high machining accuracy. These objectives can be achieved by reducing cutting temperature in the cutting zone. In metal cutting process, high cutting temperature and its detrimental effects are generally reduced by proper selection of process parameters, proper selection application of cutting fluid and using heat and wear resistance cutting tool materials. The conventional coolants are fails to provide desirable control of cutting temperature in the cutting zone and also it creates some techno-environmental problems such as disposal and dermatological problems to the user. These problems were eradicated using liquid nitrogen as coolant in cryogenic machining due its excellent cooling ability along with environmental friendliness.
