Turning is a widely used machining operation when compared to other manufacturing processes. The finished component is subjected to dimensional accuracy, required surface finish and the tool is subjected to less cutting force, minimum possible temperature and maximum tool life. In order to achieve these desired performance measures in any machining operation, proper selection of machining parameters is very essential. The present method of selection of machining parameters of machining parameters by trial and error, previous work experiences of the process planner and machining handbooks are time consuming and very tedious process. There is a need to develop a technique that could be able to find the optimal machining parameters for the desired performance measures in minimum production time and minimum production cost. In this work, Firefly Algorithm (FA) is implemented to select the optimal machining parameters such as cutting speed, feed and depth of cut in minimum possible production time and production cost on turning process. The result of FA has been compared with other optimization techniques and discussed.
