What does G-code mainly control in a CNC machine?

G-code primarily serves as a programming language that instructs CNC machines on how to perform specific tasks, particularly regarding the movement and operation of machine components. It conveys precise commands for directing the motion of the machine’s tools, such as positioning, cutting speed, and feed rates.

For example, G-code commands dictate the path a milling cutter should follow, enabling the machine to cut through materials in a highly controlled manner. This level of precision is essential for creating complex designs in various materials, and it allows for repeatability in manufacturing processes.

While other aspects like temperature settings, the visual interface, and input/output functions are important for the overall operation of CNC machinery, they are not the primary focus of G-code. G-code is specifically tailored to control the kinetic aspects of the operation rather than the peripheral features of the machine.
