In any analysis of innovation, 802.11 is truly a prime number. This evolving standard, better known as Wi-Fi, is the it protocol that s won the same spectacular hype as (whisper it softly) the Internet itself. Oh, the good old days. I miss them.

But while Wi-Fi undeniably inspires that intoxicating blend of expectation and excitement that leads to entrepreneurial excess, it s also the kind of technological platform that invites the best ideas. Wi-Fi s combination of well-crafted technical standard and regulation-free deployment offers a ....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

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
