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, se..............etc

OVERHEAD CAMSHAFT ENGINE
* INTRODUCTION :-
OHV means OverHead Valve –
An engine design where the camshaft is installed inside the engine block and valves are operated through lifters, pushrods and rocker arms (an OHV engine also known as Pushrod engine).
Although an OHV design is a bit outdated, it has been successfully used for decades. An OHV engine is very simple, has more compact size and proven to be durable.
* Classification :-
Single OverHead Cam
Double OverHead Cam
Pushrod Engines
* Single O..............etc

Camshaft


Double overhead cams control the opening and closing of the valves
The camshaft is used in IC Engines to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes or cams protruding from it, one for each valve. The cams force the valves open by pressing on the valve, or on some intermediate mechanism, as they rotate.
The relationship between the rotation o..............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,
