What does "CNC" stand for?

The term "CNC" stands for "Computer Numerical Control." This definition highlights the use of computers to control machine tools, such as lathes, mills, and routers. CNC technology allows for precise and automated machining processes through the use of programmed instructions, which results in consistent and repeatable output for manufacturing components and parts.

By automating the control of machining tools, CNC systems enhance efficiency and reduce the potential for human error during production, leading to higher quality parts. The integration of computers into the numerical control of machinery represents a significant advancement over earlier methods of manual machine operation, making CNC a vital aspect of modern manufacturing.

The other options presented do not accurately describe CNC technology. "Computerized Network Control" implies a focus on networking rather than machine operation, "Central Numerical Computing" does not relate to machining at all, and "Computer Navigation Circuit" suggests a context related to navigation rather than manufacturing machinery. Thus, "Computer Numerical Control" is the most accurate and relevant definition in the context of machining.
