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.

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

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc
