Superalloys are a much-needed material for abundant engineering fields, such as nuclear-powered reactor components and aeronautics. Owing to their exceptional characteristics, higher thermal conductivity, they can be difficult machine using conventional processes. Modern approaches machining have evolved utilize these materials. One of the techniques studied in this project is electrical discha...

In this paper, a successive discharge material removal model is proposed to predict the surface roughness of EN-GJL-250 (gray cast iron) under different parameters wire-cut electrical machining (WEDM). Firstly, finite element method (FEM) was used analogue simulate distribution temperature and flow field in WEDM single pulse process. According principle energy conservation, morphology character...

The objective of the present work was to investigate the effect of the wire electrical discharge machining process parameters on material removal rate of titanium alloy using Taguchi approach. A brass wire of 250μm was applied as a tool electrode to cut the specimen. L36 mixed orthogonal array (2 ×3) has been selected for experimentation under different variables like dielectric conductivity, p...

This paper focuses on wire electrical discharge machining (WEDM) of devices made from commercially available sintered neodymium-iron-boron (NdFeB) rare-earth magnets that have been magnetized before machining. We conduct an experimental study to quantify the effects of the voltage and capacitance of an RC-type WEDM machine, as well as the magnet polarity, on slicing rate, mean kerf, and variati...

Observations of the discharge gap were conducted to investigate plasma motion in reciprocated traveling wire electrical machining (RT-WEDM). It was found that a continuously slides on surface workpiece. An oscillating moving heat source is proposed better describe characteristics motions. Based an source, novel thermal-fluid coupling model by adopting level-set method formation crater and effec...

In this paper an attempt has been made to correlate the usefulness of electrodes made through powder metallurgy (PM) in comparison with conventional copper electrode during electric discharge machining. Experimental results are presented on electric discharge machining of AISI D2 steel in kerosene with copper tungsten (30% Cu and 70% W) tool electrode made through powder metallurgy (PM) techniq...
