Investigations Into Turning EN-24 Steel With Cryogenic Cooling

In this work the experimental study on turning of EN24 alloy steel is performed. Experiments are performed under dry, wet and cryogenic cutting conditions using uncoated tungsten carbide tool having standard geometry by varying the spindle speed (RPM) and feed (mm/rev). The experiments are performed to investigate the effect of different input parameters on tool wear (mm), surface roughness (um), tool tip temperature (oC) and tool forces i.e. feed force (Ff) and cutting force (Fc). Experimental results indicate that cryogenic cooling is one of the most favorable cooling method for turning process due to being capable of bringing considerable decline in tool wear and improvement in surface finish through control of machining temperature at the cutting zone.
