Machining experiment is carried out to minimize the energy consumprtion, surface roughness and machining cost based on turning parameters of cutting velocity, feedrate and depth of cut (Table 1). Create regression analysis to develop three objective function with second order equations. Using Genetic Algorithm, investigate and search the appropriate input process parameters for minimizing all three functions. Decide the suitable machining process constraints and GA parameters to minimize the sustainability machining process. Table 1 Turning process parameters and output response
