The increasing demand of micro or miniature parts and the development of the micro machining processes are the cause of the growing of micro wire electrical discharge machining (μ-WEDM). μ-WEDM has the ability to manufacture complicate shapes with high accuracy and provides the advantage of machining any conductive materials regardless of their mechanical properties in the absence of significan...

Wire electrical discharge machining (WEDM) is extensively used in machining of conductive materials when precision is of prime importance. Rough cutting operation in WEDM is treated as a challenging one because improvement of more than one machining performance measures viz. metal removal rate (MRR), surface finish (SF) and cutting width (kerf) are sought to obtain a precision work. Using Taguc...

In the field of Abrasive Water Jet (AWJ) machining, the current focus is on the fabrication of complex threedimensional features. The current work is aimed at using this strategy to manufacture micro-tools for machining arrays of square holes using Electric Discharge Machining (EDM). Based on selected parameters of AWJ process(step over, traverse speed, path strategy),micro tools were fabricate...

In this study, the Electric Spark Discharge Method (ESDM) was employed with micro-electrical discharge machining (m-EDM) to create an electric arc that melted two electrodes in deionized water (DW) and fabricated nano-Au colloids through pulse discharges with a controlled on-off duration (TON-TOFF) and a total fabrication time of 1 min. A total of six on-off settings were tested under normal ex...

In the present work, an experimental investigation on wire electrical discharge machining (WEDM) of Monel-400 has been presented. Monel-400 is a nickel–copper-based alloy, mostly employed in ships and corrosion-resisting applications. Four input WEDM parameters namely discharge current (Ip), pulse-on time (Ton), pulse-off time (Toff) and servo voltage (SV) have been investigated and modeled for...

Electric discharge machining (EDM) is a type of high-precision usually applied to hard-material for mold manufacturing and in the aerospace industry. Longer process times typically reduce facility efficiency. The use electrochemistry (ECM) can overcome this challenge efficiently machine large workpieces. Some industries have adopted combined these two processes Inconel 718 material machining. H...
