Abstract
This paper presents a study on the influence of process parameters on the manufacturing and environmental aspects of die sinking electrical discharge machining process using graphite as the tool electrode. This investigation included peak current, pulse duration, dielectric level and flushing pressure as the input parameters and aerosol emission rate, material removal rate and tool wear rate as the output parameters. The experiments were planned according to the Taguchi L9 orthogonal array. The effects of process parameters on the output responses were analyzed using main effect plots. Peak current was the most significant process parameter. A discussion on the optimization of process parameters is also presented in this paper.
