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

Introduction
Electron Beam Machining (EBM) and Laser Beam Machining (LBM) are thermal processes considering the mechanisms of material removal. However electrical energy is used to generate high-energy electrons in case of Electron Beam Machining (EBM) and high-energy coherent photons in case of Laser Beam Machining (LBM). Thus these two processes are often classified as electro-optical-thermal processes.
There are different jet or beam processes, namely Abrasive Jet, Water Jet etc. These two are mechanical jet proc ....etc

Abrasive Jet Machine

Introduction
Abrasive jet machining (AJM) is a non-traditional machining
process that can machine material without generating heat and
shock.
Abrasive jet machining (AJM) is commonly used for Cutting,
Cleaning, Drilling and Etching operation

Mechanism of AJM

Fine particles are accelerated in
gas stream .

The particles are directed towards
the focus of machining.

As the particle impacts the surface,
it causes a small fractu ....etc
