	Computer numerical control (CNC) is the digital manipulation of machines such as drills, lathes and other machine tools by computers and circuitry. Also known as numerical control or computational numerical control, the process comprises a series of numerical values generated by a computer; each of which is assigned to a desired tool or control position to enable the machining of a blank piece of material to precise specifications without requiring a manual operator.

Computer numerical control (CNC) refers to the digital manipulation of machines such as drills, lathes and other machine tools by computers and circuitry. Also known as numerical control or computational numerical control, the process comprises a series of numerical values generated by a computer; each of these values is assigned to a desired tool or control position to enable the machining of a blank piece of material to precise specifications without requiring a manual operator.

The process stretches back to the first CNC machines built in the 1950s and 60s which relied on punched tape (or perforated paper tape) to communicate the tool position that was controlled by a motor. The process has since been refined and improved by analogue and digital computers.

Under CNC, every object to be manufactured is allocated a G-code (an international standard language) that is stored in the machine and executed by a microcomputer (machine control unit or MCU) attached to the machine. The G-code is a set of instructions – such as the positioning or speed of the tool’s components – that the machine will follow to create or part-create the item in question. Typically, this will allow the automation of machine tools such as lathes, mills, routers, lasers and grinders.

In sophisticated manufacturing operations, G-codes are typically derived by the automatic translation of engineers’ CAD drawings into a sequential programme of machine control instructions which are then implemented. A less complex method is writing part-programmes using high-level, part-programming languages.

CNC does not rely on conventional control by cranks, cams and gears. Instead, it allows desired feed rates and cuts to be ‘dialled in’, thereby providing precise, repeatable machine movements that can be optimised for speed, feed and machine cycles.

CNC machines give flexibility of manufacture, especially when variable and complex part geometries are required. Parts can be produced in batches of just a few to several thousand.

= Benefits of computer numerical control =

* Provides highly automated, precise manufacturing;
* Does not rely on manual control;
* The part produced is a close match to the original CAD drawing, and
* Gives flexibility of batch size.

= Typical applications of CNC include: =

* 3D printing
* Lathes
* Mills,
* Water jet cutters, drills, embroidery machines, sheet metal works and glass cutting.
* CNC machines can be used both for conventional technologies, such as drills, lathes and milling machines, and new technologies such as electrical and/or chemical machining. They can also be used for other cutting machines such as lasers, oxy-fuel, plasma and water-jet technology.
