Abstract Iron based Nickel super alloys are huge requirement for marine, aero engines, chemical refinery and nuclear plant applications owing to their better-quality properties. This works focused to optimize the process parameters to maximize the shear angle that can reduce tool wear, tool life and power consumption. In the present work, an effort has been made to optimize the process parameter and investigate the influence of process parameters on shear angle in turning of A286 Iron based Nickel super alloy with different tool materials. The results indicates the optimum turning parameters are same for uncoated and PVD coated tools. The depth of cut is highly responsive by 43.76% with uncoated tool and the feed rate is highly influencing parameter by 53.76% PVD coated tool. The predicted models are in considerably good agreement with experimental results.
