What does a computer numerical control

CNC industry
The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions.
On the industrial machines there is usually a sophisticated feedback system that constantly monitors and adjusts the cutter's speed and position..
Components of CNC
Computer numerical control (CNC) is a fundamental part of modern manufacturing.
The majority of machines operate using instructions and guidelines that have been downloaded using a CNC program controller.
For a machine to interpret the commands from CNC, the commands have to be entered using G and M codes..
Most common CNC machines
CNC part programming involves a series of coded instructions that are required to produce a part.
The program controls the machine tool movements and controls auxiliary functions including spindle, coolant, and rotation.
The instructions may include numbers, letters, and symbols arranged in functional format blocks..
Most common CNC machines
Each command is made up of CNC words.
Each CNC word has a letter address and a numerical value.
The letter address (X, Y, Z, etc.) tells the control the kind of word and the numerical value tells the control the value of the word..
