Abstract

Electrical Discharge Machining (EDM) applies the concept of material eradication by utilizing electric spark erosion. The target of this exploration concentrates to examine the ideal procedure parameters of EDM on Aluminum 6061-T6as a workpiece with copper as a tool electrode. The effect of various process operators 'on machining rendering was examined. Internal factors with current (10, 20, 30) Ampere, pulse on time (50, 100, 150) μs was used after which takes pulse off time (25, 50, 75) μs. All parameters applied for empirical acts with influence on Ra (surface roughness ). The result showed that MRR" Material Removal Rate” is increment by expanding in current and pulse on time and it declines by expanding in pulse off time. Optimal condition are gained when using " Using current 30 Ampere, pulse on time is 150 μs and minimize assessment of pulse off time is 25 μs.
