What does the acronym "CNC" stand for?

The term "CNC" stands for Computer Numerical Control. This refers to a method in which a computer program is used to control machine tools in the manufacturing process. In CNC machining, a computer interprets a design created in CAD (Computer-Aided Design) software and translates it into precise movement commands for machines like lathes, mills, and routers.

The significance of CNC lies in its ability to enhance production efficiency, precision, and repeatability compared to manual machine operation. With CNC technology, complex designs can be executed with a high level of automation, minimizing human error and labor costs while ensuring consistency in production.

The other options refer to concepts that do not accurately describe the technology involved in CNC operations. Computer Network Control implies a focus on networking rather than direct machinery control, and Centralized Numerical Control suggests a central system, which does not capture the decentralized nature often utilized in CNC systems. Custom Numerical Control is not a recognized term within the context of CNC programming and operation, making it inaccurate in this context.
