'''G-code''' is a common name for the [[programming language]] that is used to programfor [[CNC]] Machine[[machine toolstool]]s.

G-code is also the name of any word in a CNC program that begins with the letter ''G'', and generally is a code telling the machine tool what type of action to perform, such as:

*rapid move

*controlled feed move in straight line or arc

*series of controlled feed moves that would result in a hole being drilled or bored

*change a tool

*turn on or off [[coolant]]

*change a [[pallet]]

*Set tool information such as offset.

There are other codes, and; the type codes can be thought of like "registers"[[register]]s in a computer

:X position

:Y position

Line 16:

:M code (another "action" register)

:F feed rate

:S [[spindle speed]]

:N line number

:R Radius

:I Arc data X axis

:J Arc data Y axis.

Warning: Different machine tools, however, may use the same code to perform different functions. : Eveneven machines that use the same CNC control. someSome may have said that "[[Fanuc]]" G-code is standard, but that is a myth.

A standardized version of G-code known as [[BCL]] is used; but on very very few machines.

G-code is understood by machine tool controls, and some machinists[[machinist]]s.

G-code is spoken by [[CAM]] software such as [[Smartcam]], [[Gibbscam]], [[Featurecam]], [[Edgecam]], [[Mastercam,]] etc. Such software must be customized for each type of machine tool that it will be used to program.

Some CNC machines use "Conversational" programming, which is a [[wizard]]-like programming mode that either hides G-code or completely bypasses the use of G-code.
