摘要：Optimization is one of the techniques used in manufacturing sectors to arrive for the best manufacturingconditions, which is an essential need for industries towards manufacturing of quality products at lower cost. Thispaper aims to investigate the optimal set of process parameters such as current, pulse ON and OFF time in ElectricalDischarge Machining (EDM) process to identify the variations in three performance characteristics such as rate ofmaterial removal, wear rate on tool, and surface roughness value on the work material for machining Mild Steel IS2026 using copper electrode. Based on the experiments conducted on L9 orthogonal array, analysis has been carried outusing Grey Relational Analysis, a Taguchi method. Response tables and graphs were used to find the optimal levels ofparameters in EDM process. The confirmation experiments were carried out to validate the optimal results. Thus, themachining parameters for EDM were optimized for achieving the combined objectives of higher rate of materialremoval, lower wear rate on tool, and lower surface roughness value on the work material considered in this work. Theobtained results show that the Taguchi Grey relational Analysis is being effective technique to optimize the machiningparameters for EDM process.
