G-code
G-code is a programming language used to control automated machine tools, primarily in computer numerical control (CNC) machining and 3D printing. It consists of commands that direct machine movements, tool operations, and auxiliary functions, enabling precise manufacturing of parts from digital designs. The language is standardized but often includes machine-specific extensions for specialized hardware.
Developers should learn G-code when working with CNC machines, 3D printers, or robotics that require automated control for manufacturing, prototyping, or fabrication tasks. It is essential for creating custom toolpaths, optimizing production processes, and integrating hardware with software like CAD/CAM systems, particularly in industries such as aerospace, automotive, and additive manufacturing.
