CNC is an acronym for which of the following?

CNC stands for Computer Numerical Control, which is a technology used in manufacturing and machining processes. This term specifically refers to the automated control of machining tools, such as drills, lathes, mills, and 3D printers, by means of a computer.

In a CNC system, a computer program containing precise instructions dictates the movements of the machine tools, allowing for high accuracy and repeatability in production. This automation enhances efficiency and consistency, which is crucial in modern manufacturing environments. The programming is typically done in a language called G-code, which defines how the machine should move and operate to create the desired part or product.

The other options do not accurately represent what CNC stands for in this context. For example, Computer Network Configuration pertains to setting up network systems and has no relation to machining processes. Centralized Numerical Command and Conventional Navigation Control are also not recognized terms related to the CNC machining process. Understanding the correct terminology is essential for working effectively in the field of manufacturing and CNC operations.
