The most widespread language for programming CAM machines is G-Code.

The commands go, in the truest sense of the word, from A (absolute or incremental position around the X-axis; turning around X) to Z (absolute or incrementing in the direction of the Z-axis). Commands prefixed with M (miscellaneous) transmit other instructions to the machine. Switching coolant on/off is an example of an M command.

G pour GO, commande les déplacements.
M pour Machine, commande les actions machines comme allumer ou éteindre le "spindle"

pour les curieux, G-Code Commenter :

This small example would mill a square
