Optimization of Machining Parameters for cutting temperature on turning of Niobium alloy C-103by using RSM

Niobium based super alloys are an unusual class of metallic materials with an exceptional combination of high temperature strength, toughness, and resistance to degradation in corrosive or oxidizing environments. The focus of present work was to study the effect of cutting parameters – speed, feed and depth of cut on the machinability of Niobium C-103 under dry machining condition using response surface methodology (RSM). In present study various machinability models were developed. This machinability models defined a functional relationship between cutting variables and response (Cutting Temperature). Cutting levels for experimentation was selected based on the cutting insert manufacturer recommendations. The analysis shows that Cutting speed is the most evident factor for cutting temperature.
