Computer Numerical Control (CNC) is a technology that uses computers to control machine tools. This process allows for precise and automated manufacturing of parts and products. CNC machines can cut, shape, and engrave materials like metal, wood, and plastic based on digital designs. CNC systems operate using a computer program that translates design specifications into machine movements. This automation improves efficiency and accuracy, reducing human error. Common applications of CNC include 3D printing, laser cutting, and milling, making it essential in industries such as aerospace, automotive, and manufacturing.
