Analysis of Machining Parameters in Turning Operation on Duplex 2205 by using RSM for Vehicle Structure

Turning is the machining process carried out to make cylindrical parts. Since the process is economical and the flexibility of turning operation is high, the process has become highly versatile among the industrial scenario. The design of experiments concept along with response surface methodology is used to analyze the machining parameters such as spindle seed, feed rate and depth of cut, of the turning operation. Three levels of spindle speed, feed rate and depth of cut are used as input parameters and their corresponding responses such as material removal rate (M.R.R), surface roughness, feed force, thrust force and cutting force are considered as the output parameters. The main aim of this experimentation process is to identify the optimal process parameters to get high M R R and low surface roughness. During high spindle speed, the M R R is high and vice versa. Surface roughness is high when its corresponding spindle speed and depth of cut is high. A high spindle speed, the chip formation is continuous whereas in medium speed, discontinuous chip is formed. M.R.R is high when spindle speed, depth of cut and feed rate are high.
