Multi-objective optimisation of die sinking electro discharge machining process using Taguchi

چکیده
The objective of this paper is to determine the optimal setting of the process parameters on the electro-discharge machining (EDM) machine while machining AISI H13 tool steel. The parameters considered are pulse current, pulse-on-time, pulse-off-time and gap voltage ; whereas the responses are Tool wear ratio (TWR) and material removal rate (MRR). The optimal setting of the parameters are determined through experiments planned, conducted and analysed using the Taguchi method. It is found that the Tool wear ratio reduces substantially, within the region of experimentation, if the parameters are set at their lowest values, while the parameters set at their highest values increase the MRR drastically.
