Abstract

In the modern manufacturing scenario, efforts are continuously being made to improve the performance of advanced machining processes. Electrochemical discharge machining (ECDM) is a hybrid non-traditional machining (NTM) process, which makes use of the combined advantages of two single-action NTM processes, i.e. electrical discharge machining and electrochemical machining. As a result, the performance characteristics of ECDM process are considerably different from those of the two single-phase processes with respect to productivity, accuracy and surface quality. Selection of the optimal process parameters is always crucial towards fully utilizing the benefits of ECDM process. In this paper, an a posteriori approach based on the novel bird mating optimizer (BMO) is applied for multi-objective optimization of ECDM responses. In this approach, the complete spectrum of non-dominated Pareto optimal solutions, from which the process engineers can easily choose the desired parametric setting depending on the application domain, is developed. It is much more useful from a practical standpoint than a priori approaches reported in the literature. The BMO is also used to predict the overall trends of the multi-parameter dependent responses, without the need of holding any of the process parameters constant during analysis.
