Abstract

“Electro-Discharge Machining (EDM)” is a widely utilized non-conformist machining proceduresed for material eliminationin aerospace, die making, automotive and other organizations. The present study focuses on investigating the outcome of procedurevari ables like“gap voltage (Vg), sensitivity, beat on time, Pulse off time (Toff) and diameter of the tool” on “material elimination rate (MER)”. The work piece used is high-speed steel (HSS) and the device material used is “electrolytic copper (Cu)”. “Taguchi’s L9 orthogonal array” has been utilized to carry out the tests. Minitab 17 software has been used for the analysis. Considering the result of various factors on process, the effect of the significant process parameters needs to be investigated. The process parameters havebeen observed to have different effect on the machining process and the output responses are dependent on them. Hence finding out the utmost appropriate set of procedure variables to increase the material removal rate for wire EDM process needs investigation for which process optimization may be used. MRR is observed be maximum if gap voltage is 5, sensitivity 5, pulse on interval will be 5 and pulse off interval will be 1.
