Experimental Investigation on Effect of Machining Parameters of EN353 Alloy Steel Using Nano Fluids

Mechanical Engineering

2nd National Conference on Recent Trends & Innovations in Mechanical Engineering

Almost all machining process produces heat and friction which will potentially damage the cutting tools as well as the machined work piece. To reduce the friction, heat transfer and to remove metal particles away from the cutting zone normally lubricants/cutting fluids are widely used in metal cutting industries during machining operation The objective of the present work is to find out the set of optimum conditions for the selected process parameters, using a nano fluid mixture of Al2O3 and water. Taguchi method is used to determine the optimum cutting parameters viz. cutting speed, feed rate, depth of cut and type of tool at three different levels. The Experiments are carried out using L9 (34) orthogonal array and the work material used is EN 353 Alloy Steel. Nano fluids have novel properties that make them potentially useful in heat transfer medium in cutting zone. The Minimum quantity lubrication (MQL) presents itself as a viable alternative for turning with respect to tool wear, heat dissipation, and machined surface quality etc. This study compares the mechanical performance of MQL based Nano fluids and flooded based Nano fluid for the turning operation of EN353. As it was observed that machining under MQL and Flooded conditions the results generated are almost same, by which we can conclude that MQL is a better alternate cooling technique than flooded cooling.
