Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant alloys. EDM can be used to machine difficult geometries in small batches or even on job-shop basis. Work material to be machined by EDM has to be electrically conductive. EDM is sometimes called spark machining because it r ....etc

Finite-Element Simulation of Electrical Discharge Machining (EDM) Process


I. INTRODUCTION
Electric discharge machining (EDM), sometimes
colloquially also referred to as spark machining, spark
eroding, burning, die sinking or wire erosion, is a
manufacturing process whereby a desired shape is obtained
using electrical discharges (sparks). Material is removed
from the workpiece by a series of rapidly recurring current
discharges between two electrodes, separated by a dielectri ....etc

Removel of material by using electron beam and electrical field.
ELECTRON BEAM MACHINING :
A high velocity stream of electrons is focused on the workpiece surface to remove material by melting and vaporization
Electron beam gun accelerates a stream of electrons to 3/4 c and focused through an electromagnetic lens
Kinetic energy of beam converted to thermal energy of extremely high density, melting or vaporizing material in a very localized area
EBM must be carried out in a vacuum
MATERIAL PROCESSING BY ELECTRON BEAM:
High in ....etc

ABSTRACT
High intensity discharge lamp (HID) presently used for urban street light are based on principle of gas discharge, thus the intensity is not controllable by any voltage reduction method as the discharge path is broken. White Light Emitting Diode (LED) based lamps are soon replacing the HID lamps in street light. Thus intensity control is now possible by pulse width modulation based on sensing the movement and density of vehicles. The pulse width becomes very narrow on sensing no movement of vehicles. As the ....etc
