G-code
G-code is a programming language used to control automated machine tools, such as CNC machines, 3D printers, and laser cutters. It consists of commands that specify tool movements, speeds, and other operational parameters to manufacture parts from digital designs. The language is standardized but often includes machine-specific extensions for precise control.
Developers should learn G-code when working in manufacturing, robotics, or prototyping fields that involve computer-aided manufacturing (CAM). It is essential for programming CNC machines to cut, drill, or shape materials, and for 3D printing to control layer-by-layer fabrication. Knowledge of G-code enables customization of machine operations, debugging of manufacturing processes, and integration with CAD/CAM software.
