原始语种摘要: Abstract(#br)To improve the fabrication efficiency of three-dimensional (3D) microelectrode and to eliminate the discharge ridges on microstructures that are machined by laminated microelectrodes, Sn-plated Cu foils were used to prepare a bundled 3D-laminated microelectrode. The microelectrode was then applied in reverse-polarity powder-mixed electrical discharge machining (PMEDM) via a uniformly suspended EDM oil that contained graphite (Gr) and Cu powders. The effect of the process parameters on the discharge ridges of the microstructure, including concentrations of Gr and Cu powders, voltage pulse width T on , pulse interval T off and machining voltage U , was studied in detail. With the optimized process parameters, 3D microstructures with depths of nearly 800 μm were processed. The...
