1. Types of NC System Machine controls are divided into three groups: (a) Traditional numerical control (NC); (b) Computer numerical control (CNC); (c) Distributed numerical control (DNC).
The original numerical control machines were referred to as NC machine tool.

The history of CNC machines dates back to John Parsons, who is credited with the first CNC machine.
CNC technology has evolved for several decades from punch tape-controlled devices to computer-programmable machines..

The most basic function of any CNC controller is automatic, precise, and consistent motion control.
All forms of CNC equipment have two or more directions of motion, called axes.
These axes determine precisely and automatically the position of the workpiece..

How has computer numerical control changed over time?

Early CNC machines in the 1940s and 1950s used punched tape, which was then commonly used in telecommunications and data storage.
This technology was replaced by analog computing technologies.
From the 1960s into the 1970s, digital technologies emerged, making the production process automated and more efficient._{Sep 28, 2019}.

How is computer numerical control CNC used today?

Computer numerical control (CNC) is a manufacturing method that automates the control, movement and precision of machine tools through the use of preprogrammed computer software, which is embedded inside the tools.
CNC is commonly used in manufacturing for machining metal and plastic parts..

What effect has numerical and computer control had on manufacturing?

CNC offers greatly increased productivity over non-computerized machining for repetitive production, where the machine must be manually controlled (e.g. using devices such as hand wheels or levers) or mechanically controlled by pre-fabricated pattern guides (see pantograph mill)..
