G Code List
G-code (also known as RS-274) is the name of the most prevalent programming language for computer numerical control (CNC) in computer-aided design and manufacturing (CAD/CAM). G-code provides metric-based numeric control of CAM-controlled equipment such as CNC milling machines.
G-code is the simple programming language for CNC machines. It consists of lines of code that are organized in blocks. Each block controls one CNC machining operation, such as a cutting operation with a specific tool. Each line in a block is labeled with the letter N and a number.
