Characteristic Analysis of EDMed Surfaces Using the Taguchi Approach

Electrical discharge machining of titanium alloy (Ti–6Al–4V)

“…A study by Lee and Yur [7], have shown that the most efficient parameters are pulse current and pulse duration on the surface integrity of the material among the other EDM parameters. Hence, these two principle EDM parameters were selected for this study also and the experiments were established upon full factorial design of these parameters.…”

Processing of Zirconium-Based Bulk Metallic Glass (BMG) Using Micro Electrical Discharge Machining (Micro-EDM)

“…Two factors influencing the thickness of the recast layer are magnitude of discharge current and duration of pulse-on time [12]. Thus, the higher discharge current and pulse-on time associated with a higher input energy produces a larger amount of molten material, which subsequently flows over the rim to solidify as burrs.…”

The study of EDM hole-drilling method for measuring residual stress in SKD11 tool steel

“…Thus this current study also employs this EDM condition for examining the reliability of EDM hole-drilling method on the SKD11 tool steel. From the previous studies of Lee et al [12,13], they used the Taguchi approach and found that the characteristics of an EDMed surface, such as hole enlargement, surface roughness and white layer thickness (WLT), are mainly influenced by the pulse current and the pulse-on duration. Since the EDM energy (E) can be expressed as the product of open-circuit voltage (V p ), pulse current (I p ) and pulse-on duration (τ on ), i.e.…”
