The Effect of Current Rates on Surface SKD 11 for Electrical Discharge Machine Die Sinker
The effect of low current rates are determined by machining pits on SKD 11 (tool steel) surface using electrical discharge machine die sinker. Various parameters are considered during machining such as current, gap voltage and EDM oil. In this experiment, three current levels are set at 0.5A, 1.5A a...

| Summary: | The effect of low current rates are determined by machining pits on SKD 11 (tool steel) surface using electrical discharge machine die sinker. Various parameters are considered during machining such as current, gap voltage and EDM oil. In this experiment, three current levels are set at 0.5A, 1.5A and 3.0A. Besides that, a copper electrode with diameter 0.5mm is used. From Microscopy Imaging Analysis (MIA) the distinction diameter holes and shapes can be seen. The result in this experiment shows that, the shape of surface SKD 11 is circle as expected compared to the highest currents used. Overall, this study shows that presence of surface modification in the future will help human to handle tool and machinery part more easily thus improve the existing technology available in surface modification. |
