Experimental Investigation on the Effect of Process Parameters for CNC Turning of UNI Al 3055 Alloy Under MQCL Based Cooling Technique

Abstract

In the present research a novel cooling setup that can help the turning process to be performed in various media, i.e., dry, liquid CO 2 or compressed air, cooling lubricant, and the mixture of the liquid CO 2 or compressed air mixed with the cooling lubricant. The conventional cooling oil is used to dissipate the heat and increasing life of a cutting tool. So, the surface finish of the workpiece improves leading to a better quality product. Customarily, the contaminated cutting fluid needs to be disposed of after its use that involves a good amount of money of total manufacturing cost. Primarily this work is a turning operation on Al 3055 alloy under three different cutting media namely dry, Liq. CO 2 and Liq. CO 2 assisted the minimum quantity of liquid in order to get better quality of the product.
