HIGH SPEED MACHINING
ABSTRACT
Over the past 60 years, high speed machining (HSM) has been applied to a wide range of metallic and non-metallic work piece materials including the production of components with specific topography requirements and machining of materials with hardness of 50 HRC and above.
With most steel components hardened to approximately 32-42 HRC, machining operations currently include:
Rough machining and semi-finishing of the material
Heat treatment to ach ....etc

Ion Beam Machining
Ion source
The Ion Source has arrays of permanent magnets to produce a multi-cusp magnetic field in regions remote from the plasma grid and the RF antenna.
The field confines the plasma by lengthening the path of ionizing electrons and reducing their drift to the walls.
Plasma sources generate plasmas.
Excitation of plasma requires partial ionization of neutral atoms and/or molecules of a medium.
There are several ways to cause ionization: c ....etc

A SEMINAR ON
ADAPTIVE CONTROL MACHINING
ABSTRACT

Adaptive control system is a logical extension of the CNC-mechanism. In CNC mechanism the cutting speed and feed rates are prescribed by the part programmer. The determination of these operating parameters depends on the Knowledge and experience regarding the work piece, tool materials, coolant conditions and other factors.
By contrast in adaptive control machining, there is improvement in the production rate and reduction in t ....etc

In electron-beam machining (EBM), electrons are accelerated ..
In electron-beam machining (EBM), electrons are accelerated to a velocity nearly three-fourths that of light.

The process is performed in a vacuum chamber to reduce the scattering of electrons by gas molecules in the atmosphere.

The stream of electrons is directed against a precisely limited area of the workpiece;

on impact, the kinetic energy of the electrons is converted into thermal energy that melts and vaporizes the material to be removed, forming holes or cuts.

MANUFACTURING THROUGH ELECTRO CHEMICAL MACHINING




ABSTRACT:

The machining of complex shaped designs was difficult earlier, but with the advent of the new machining processes incorporating in it chemical, electrical & mechanical processes manufacturing has redefined itself. This paper intends to deal with one of the revolutionary process called Electro Chemical Machining (ECM).

INTRODUCTION:

Electro chemical machining (ECM) is the controlled removal of metal ....etc

WATERJET MACHINING
Introduction to Water jet
It is the fastest growing machining process.
One of the most versatile machining processes.
Compliments other technologies such as milling, laser, EDM, and plasma.
True cold cutting process – No HAZ , mechanical stresses or operator and environmental hazards.
Not limited to machining – but also used in food industry applications.
Evolution of Waterjet :
