INTRODUCTION
BHEL was established more than 50 years ago when its first plant was setup in Bhopal ushering in the indigenous Heavy Electrical Equipment Industry in India. A dream which has been more than realized with a well recognized track record of performance it has been earning profits continuously since 1971-72 and achieved a turnover of Rs 2,658 crore for the year 2007-08, showing a growth of 17 per cent over the previous year. Bharat Heavy Electricals Limited is c ....etc

constructional aspects of gas insulated substation
It is very much required to establish an electrical substation at load center. Since, establishing a substation at load center is quite economical and profitable in many aspects. As it reduces length of feeders and due to short length feeders, the quality of voltage regulation improves. But the main obstruction of establishing a substation at load center is space. Generally main load center of any place is situated at very congested place where, sufficient land for establishing conventional el ....etc

Numerical control has caused a virtual revolution in the discrete metal parts manufacturing industry. The success of NC has led to number of extensions of Numeric Control concepts and technology. Four of the important developments are the following:
Direct numerical control (DNC).
Computer numerical control (CNC).
Adaptive Control.
Industrial robots.
Direct Numerical Control(DNC)
There are number of problems inherent in conventional machiningwhich are motivated machine tool builders to seek imprivements in the basic NC system. Among the diffi ....etc

NC and CNC machines and Control Programming
Motivation and uses
To manufacture complex curved geometries in 2D or 3D was extremely expensive by mechanical means (which usually would require complex jigs to control the cutter motions)
Machining components with repeatable accuracy
Advantages of CNC
Easier to program;
- Easy storage of existing programs;
- Easy to change a program
- Avoids human errors
- NC machines are safer to operate
- Complex geometry is ....etc
