Parametric analysis and optimization of wire electrical discharge machining of γ-titanium aluminide alloy

This paper presents an investigation on wire electrical discharge machining of gamma-titanium aluminide alloy. An extensive research study has been carried out with an aim to select the optimum cutting condition with an appropriate wire offset setting in order to get the desired surface finish and dimensional accuracy. The process has been modeled using additive model in order to predict the response parameters i.e. cutting speed, surface finish and dimensional deviation as function of different control parameters and the main influencing factors are determined for each given machining criteria. Finally, the optimum parametric setting for different machining situation arising out of customer requirements have been synthesized and reported in the paper. (C) 2004 Elsevier B.V.
