Modeling and Analysis of Cutting Force in Turning of AISI 316L Stainless Steel (SS) under Nano Cutting Environment

Abstract

Nano Cutting fluids play a significant role in machining operations and impact shop productivity, tool life and quality of work. In the present work, machining performance of AISI 316L Stainless steel (SS) is assessed under nano cutting environment. Experiments are performed by plain turning of 80mm diameter and 300mm long rod of AISI 316L SS on NAGMAT centre lathe under wet machining with and without Multi Wall Carbon nano Tubes (MWCNT) inclusions in the conventional lubricant. The Second order quadratic models were developed to predict cutting forces using response surface methodology (RSM) based D-optimal design. Machining parameters such as speed, feed rate and depth of cut are chosen as numerical factor, and the wt % of MWCNT content is considered as the categorical factor. Furthermore, using analysis of variance method, significant contributions of process parameters have been determined. Experimental results reveal that wt % of MWCNT and feed rate are the dominant variables on responses.
