“…M.P.Samule and P.K. Philip in 1996ignited a new idea of the use of powdered metallurgy processed electrodes [14]. Tsai et al (2003) investigated the use of copper-chromium sintered electrodes and achieved machined surface with lesser micro cracks.…”

Un-conventional or non-traditional machining methods generally create a phantasm in mind that these are very new. In reality these methods are named so because of the process mechanism in which no shear force is used directly neither there is any contact between tool and workpiece. This does not insinuate that these processes are new because 1694 saw the dawn of EDM when Sir Robert Boyle described the phenomena of electric discharges, 1952 saw the birth of electron beam technology andin the year of 1957 and Gordon Gould designed the first laser device. All these non-traditional processes have developed rapidly in last few decades and are now the state of the art of the present manufacturing technology. Among these EDM has accrued a lot because of its advantages over other non-traditional processes. This accruement is result of various unprecedented ideas those changed the countenance of EDM and made it more efficient and economic process among the non-traditional processes. This paper presents the literature survey to throw light on all those ideas those lead to the current state of the art of EDM.

“…Samule and Philip in 1996 were the first to use the PM processed electrodes and these electrodes played a great role in the surface modification [14,75]. Wang et al(2002) proposed the method of electric discharge coating (EDC) to modify the surface using powdered Ti in dielectric and boosted PEDM for surface treatment.…”

“…Some dark strips on the copper-tungsten electrode surface were found because copper containments melted and wore more easily than tungsten containments. The tungsten particles therefore bulged during EDM and then became bridges between electrode and workpiece [5]. These bulged particles connected with burned carbide showing dark strips.…”

“…The ease of manufacturing these tools and their versatility especially for diesinking operations has been the prime motivator. The use of powder metallurgy tool electrodes for performance evaluation by Samuel and Philip [8] highlight further novel concepts in EDM. They demonstrated that it was possible to combine desired properties of different materials by altering physical properties through compacting pressure and sintering temperature, and this allows-for example-the embedding of tungsten in conductive copper matrix tools.…”

This paper describes a collaborative research programme aimed at investigating the use of quick EDM electrodes obtained via appropriate rapid prototyping techniques in finishing laser-sintered tools. Two methods were employed in obtaining the EDM electrodes: copper coating of stereolithography models and copper coating of direct metal laser sintered (bronze) models.The amount of copper deposited on both electrode models proved problematic as the electroplating process was unable to deposit enough copper in the inner cavities of the electrodes, with very gradual reduction in copper layer thickness from the outer faces/ surface to virtually no deposition in the inner walls and bottom face. Consequently, the electrodes were not suitable for the envisaged EDM process.
