What is CNC?

CNC stands for Computer Numerical Control. It's a manufacturing process that uses computerized controls to operate machine tools.

Working Principle

- The CNC system reads a set of coded instructions (the G - code and M - code). These instructions tell the machine tools, like milling machines, lathes, or routers, how to move and operate. For example, in CNC milling, the machine precisely cuts away material from a workpiece to create a specific shape according to the programmed instructions.

Advantages

- High Precision: It can achieve very accurate and repeatable results. For example, in the production of aerospace components, CNC machining can ensure that parts are made with extremely tight tolerances.

- Increased Productivity: Once programmed, the CNC machine can work continuously and often at a faster speed than manual operation. It also allows for lights - out manufacturing, where the machine can operate without human supervision for extended periods.

Applications

- Automotive Industry: CNC machines are used to manufacture engine parts, transmission components, and body parts.

- Aerospace: To produce turbine blades, structural components of aircraft, and other precision parts.

- Furniture Making: For cutting and shaping wood or other materials to create furniture components with complex designs.
