Abstract
The purpose of this study is to determine the effect of the power supply current on recast layer on S45C steel cutting using wire EDM. In this research, the process of cutting workpieceused Mitsubishi Wire EDM Machine BA-8. Brass wire electrodes used 0.2 mm and work piece material S45C 22 mm. The workpiece was cut into a circle to get 20 mm diameter with EDM wire machine with current power supply value of 4, 5, 6, 7, and 8 amperes. The results showed that the greater the power supply current used to produce thicker recast layer and the greater the hardness value was. The highest thickness value occurred at 8 Ampere power supply current variance of 35 μm. And the highest hardness value alsooccurred on the variation of 8 Ampere current power supply of 277.3 VHN.
