Application of NSGA-II for optimisation of cylindrical plunge grinding process parameters

Cylindrical grinding (finishing) operation is widely used for obtaining accurate surface finish on components in automobile sectors. Present industries are facing a challenge of producing high quality components with low power consumption and low manufacturing cost due to increased competition. In this paper, optimum process parameters values are obtained for dressing depth of cut, dressing cross feed rate and grinding feed rate of cylindrical plunge grinding operation. Experiments were performed as per L9 orthogonal array with replica on computer numerical control angular head grinding machine. Mathematical model has been developed using response surface methodology for determining grinding responses. The results of RSM are further used to obtain Pareto front optimal solutions using NSGA-II approach. A novel method is developed to obtain grinding ratio. The established results are helpful to decide optimal grinding parameters. © 2019 Inderscience Enterprises Ltd.
