In The Manufacturing field, and particularly in the area of metal working, Numerical Control Technology has caused something of a revolution. Even in the days before computers became standard equipments in every company and in many homes, the machine tools equipped with Numerical Control System found their special place in the machine shops. The recent evolution in the microelectronics and the never ceasing computer development, including its impact on Numerical Control, has brought significant changes to the manufacturing sector in general and metalworking industry in particular.
Numerical control can be defined as an operation of machine tools by means of specifically coded instructions to the machine control system.
In instructions are combinations of the letters of alphabet, digits and selected symbols, for example, a decimal point, the percent sign or parenthesis symbols. All instructions are written in logical order and a predetermined form. The collection of all instructions necessary to machine a part is called an NC Program, CNC Program, or a Part Program. Such a program can be stored for a future use and used repeatedly to achieve identical machining results at any time.
