CNC Programming is the process of creating instructions for Computer Numerical Control machines, which automate the operation of tools like lathes, mills, and routers. These machines follow precise commands to cut, shape, and finish materials such as metal, wood, and plastic, ensuring high accuracy and repeatability in manufacturing. The programming is typically done using a specialized language called G-code, which tells the machine how to move, what speed to use, and how deep to cut. By using CNC Programming, manufacturers can produce complex parts efficiently, reducing human error and increasing production speed.
