There is a significant importance to improve the productivity and tool life as preferred by the manufacturers. The most emerging needs of modern metal cutting operations are to increase the Material Removal Rate with surface finish and high accuracy. These objectives can be achieved by reducing the tool wear rate, this rate of tool wear can be reduced by the reduction of heat generated during the metal removal process. This reduction of heat generated can be done by use of coolant for more effective cooling a special sub cooling process known as cryogenic cooling is used while machining.
