CNC stands for?

• A. Computer Numerical Control
• B. Computer Aided Design
• C. Computer Integrated Manufacturing
• D. Computer Aided Manufacturing

Answer: (A)

CNC stands for Computer Numerical Control. This means a machine tool is driven by a computer that follows a set of numeric instructions to move the tool along different directions with high precision. The numerical data tells the machine how far to move, in which direction, and how fast, often using codes like G-code. This setup lets operators automate complex, repeatable operations such as milling, turning, or routing, delivering consistent results and tight tolerances without manual guiding.

To see how it fits in the broader workflow, consider that design work is often done in CAD, and CAM uses that design data to generate the toolpaths that CNC machines execute. CIM, or Computer Integrated Manufacturing, aims to coordinate the whole manufacturing process. So CNC is specifically about the computer-controlled operation of the machine tool, not the design phase or the full factory integration.
