CNC (Computer Numerical Control) is the computerized control of machines which are used in manufacturing. CNC uses computers to understand digital instructions (G-code) and accurately control the movement of machines like lathes, mills, and routers. CNC provides high accuracy, and efficiency hence it is used in automotive, aerospace, electronics, and metalworking.
