Final answer:
The positioning of the machining cutter is controlled by G-codes. G-codes are a set of commands used by computer numerical control (CNC) machines.
Step-by-step explanation:
The positioning of the machining cutter is controlled by G-codes. G-codes are a set of commands used by computer numerical control (CNC) machines to control the position, movement, and speed of the machining tool. These codes determine the path and actions that the cutter takes to produce the desired shape or cut.
