what is cnc code
CNC code, also known as G-code, is the fundamental programming language used in Computer Numerical Control (CNC) manufacturing. This specialized code serves as a set of instructions that directs CNC machines on how to move and operate during the manufacturing process. The code consists of a series of commands that control various aspects of machine operation, including cutting tool movement, spindle speed, feed rate, and coolant flow. Each line of code represents a specific action or movement, enabling precise control over the manufacturing process. CNC code follows a standardized format that includes letter addresses and numerical values, making it universally applicable across different CNC machines. The code can be generated manually by experienced programmers or automatically through Computer Aided Manufacturing (CAM) software. Modern CNC systems can interpret complex codes to create intricate parts with exceptional accuracy and repeatability. The technology supports various manufacturing processes, including milling, turning, drilling, and cutting, making it essential in industries such as aerospace, automotive, and medical device manufacturing.
