Abstract
In the present study textured tungsten carbide cutting tool was used to machine on stainless steel 316 bar stock. Cutting velocity and feed rate with the range of 70-170 m/min and 0.1- 0.5 mm/rev respectively were chosen as input process parameters. The tool life and machining time are considered as responses for the proposed experiments. Unit production cost (USD) was calculated with standard assumptions. The investigation reports maximum tool life and minimum machining time required for defined volume of metal removal. Evolutionary algorithm was adopted to optimize the input parameters for minimum production cost. The optimal process parameter is 164.58 m/min cutting velocity, 0.5 mm/rev feed rate, 14.99 minutes tool life, 12.27 machining time were found for minimum unit production cost (9.26 USD).
