in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...

In this paper, fuzzy logic integrated with the Taguchi method is used to optimize Wire Electro Discharge Machining (WEDM) process with multiple quality characteristics. Rough machining with EDM gives poor surface finish and has micro cracks and pores. Finish machining gives better surface finish but with very poor machining speed (MRR). Spark gap width is one of the important performance measur...

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...

This paper studies micro structure fabrication by means of a textured tool cutting edge, which is manufactured by applying the wire cut electrical discharge machining (WEDM). Machining performance of the square structure fabrication on the tool cutting edge is investigated in the WEDM process, and the machining accuracy is explored in experimental analyses. In this proposed method, undesired ov...

in the present paper, the study has been made to optimize the process parameters during machining of Inconnel-600 by wire electrical discharge machining (WEDM) using response surface methodology (RSM). Four input process parameters of WEDM (namely Peak Current (IP), Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Feed rate (WF)) were chosen as variables to study the process performance in t...
