| Abstract Scope |
Increasing awareness and concerns on the emission of obnoxious fumes during the electrical discharge machining (EDM) using the hydrocarbon (HC)-based dielectric oils have compelled the researchers to develop an environmentally-friendly variant of EDM process. The dry and near-dry variants of the EDM process have the potential to become a replacement for the conventional HC-based EDM variant. The concept of a near-dry variant is similar to that of the minimum quantity lubrication (MQL) method. Near-EDM process has gained attention for machining of macro-sized features. However, scant literature is available on machining of micro-sized features. Therefore, the present research deals with the fabrication of micro-channels on Ni-Ti based shape memory alloy. Further, the effect of process parameters (like current, pulse on-duration, pulse off-duration) was assessed on the volumetric material removal rate, average surface roughness, and width-overcut. The two-phase mixtures of glycerin-in-air, water-in-air, and EDM oil-in-air were tested as the dielectrics. |
