Main aim is to optimize a manufacturing process by using different Meta-heuristic algorithm. i had selected turning process here. Firstly i found the most influential parameters in turning process by introducing "Local-centrality Method". Optimization of these most influential parameters will lead to the optimization of whole process using "Genetic algorithm and Taguchi Method". Genetic algorithm has been used to optimize production rate & production cost and Taguchi method has been used to optimize cutting quality, which has been described in presentation.
