Nowadays, micro-machining techniques are commonly used in several industrial fields, such as automotive, aerospace and medical. Different technologies available, the choice must be made considering many factors, type of machining, number lots required accuracy specifications terms geometrical tolerances surface finish. Lasers electric discharge machining (EDM) widely to produce micro-components...

A sequential process combining laser beam micromachining (LBMM) and micro electro-discharge machining (?EDM) for the micro-drilling purpose was developed to incorporate both methods’ benefits. In this process, a guiding hole is produced through LBMM first, followed by ?EDM applied that same more fine machining. This facilitates stable, efficient regime with faster processing (compared pure ?EDM...

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...

In this work the electric discharge machining (EDM) implementing with multi-wall carbon nanotubes (MWCNT) as a miniscule electrode for pursuing precise surface modification was studied. The excellent upright growth of carbon nanotubes on copper based alloy substrates by a radio frequency (RF) assisted hot filament chemical vapor deposition (HFCVD) method suggests us to exploit MWCNTs as the min...

Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...

Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a work piece in the presence of a dielectric fluid. Aluminium metal matrix composites (AMMCs) refer to the class of light weight high performance aluminum ceramic material systems. The reinforcement in AMMCs could be in the f...

Together, 316L steel, magnesium-alloy, Ni-Ti, titanium-alloy, and cobalt-alloy are commonly employed biomaterials for biomedical applications due to their excellent mechanical characteristics resistance corrosion, even though at times they can be incompatible with the body. This is attributed poor biofunction, whereby tend release contaminants from attenuated surfaces. Coating of surface theref...

The wire cut EDM is one of the most important machining process for technologists in the field of moulds, dies and in precision manufacturing .The wire electrical discharge machining producing parts with in very short period , the demand over the time increases extensively .So that an extensive research work has been carried out to optimize the parameters of the process by eliminating trial and...

Electro discharge machining (EDM) is a process that uses an electric sparks to generate the high temperature and melt the workpiece. One of the EDM process is drilling. In EDM drilling, an electro thermal mechanism is introduced between the electrode and work piece to create the hole. The hole size is dependent on the diameters of electrode used during the drilling process. The present study pe...
