Abstract
Electrical discharge machining (EDM) is a process for shaping hard metals and forming deep complex shaped holes by arc erosion in all kinds of electro-conductive materials. The objective of this paper is to investigate how the polarity, peak current, pulse on duration, pulse off duration and servo voltage in EDM effect on material removal rate (MRR), electrode wear ratio (EWR) and surface roughness (SR). The effectiveness of EDM process with titanium alloy (Ti-6Al-4V )through electrical discharge machining (EDM) using copper tungsten (CuW)as an electrode.It is observed that copper tungsten (CuW) is most suitable for use as the tool electrode in EDM of Ti-6Al-4V .Better machining performance is obtained generally with the electrode as the cathode and the workpiece as an anode. In this research, a study was carried out on the influence of the parameters such as polarity, peak current, pulse on duration, pulse off duration and servo voltage. The surface quality that was investigated in this experiment was surface roughness using perthometer machine. Material removal rate (MRR) and electrode wear (EW) in this experiment was calculated by using mathematical method. The result of the experiment then was collected and analyzed using MINITAB software. This was done by using the technique of design of experiments (DOE) and technique such as ANOVA analysis. This analysis was purposed to select the optimal machining condition for use in confirmation test.
