Abstract
The objective of this paper is to obtain an optimum setting of turning parameters for to get an optimum value of surface roughness and MRR while machining AISI420 stainless steel using CNMG inserts. Turning process parameters included spindle speed, feed, depth of cut and insert nose radius. A total number of 9 experiments conducted with orthogonal array. Attempt has been made to optimize the process parameters using Taguchi method. Minitab statistical software used for the analysis of the experimental work. After experimentation and analysis it shows that feed affects greatly on MRR followed by DOC. For to achieve maximum MRR all process parameters has to be at level 3. In case of surface roughness, feed is a major influencing parameter followed by insert nose radius. To get good surface finish spindle speed, DOC, insert nose radius to be at level 3 and feed has to be at level 1.
