what is cnc code

CNC code refers to the programming language used to control computer numerical control (CNC) machines. CNC machines are automated manufacturing tools that perform precise and complex operations on various materials, such as cutting, milling, and drilling. CNC programming involves writing a series of commands, typically in the form of a programming language, G-code, that specifies the actions the CNC machine should take. These commands include information about tool movements, spindle speeds, feed rates, tool changes, and other parameters necessary to carry out a specific machining operation. G-code is the most widely used CNC programming language. It provides metric-based numeric control of CAM-controlled equipment such as CNC milling machines. G-code commands are typically represented by a combination of letters and numbers, and each command has a specific function and is executed sequentially by the CNC machine. Although different manufacturers of the machine tool may adopt their own use for certain G-codes, there is a core group that is standardized.
