What is CNC?

CNC stands for Computer Numerical Control. It’s a technology that uses computers to control machine tools, such as mills, lathes, routers, and 3D printers. 

Instead of manually operating the machines, CNC allows for precise and automated control of their movements and operations. 

Users can create designs using computer-aided design (CAD) software, which are then converted into instructions that the CNC machine follows to produce the desired object. 

CNC technology enables efficient and accurate manufacturing processes, making it widely used in industries ranging from manufacturing and engineering to prototyping and hobbyist projects.
