What does the term "CNC" stand for?

The term "CNC" stands for "Computer Numerical Control," which accurately describes a method used in modern manufacturing for controlling machine tools via computer systems. In CNC machining, the computer is programmed with specific instructions that guide the machine in performing precise movements to create parts, cut materials, or shape products according to digital designs.

This technology allows for high precision and efficiency, as algorithms govern machinery operation based on numerical data. The PCs used in CNC machines interpret this data to generate movements, making it an essential advancement in tool and die making, as well as various other manufacturing processes.

Other terms listed, such as "Computerized Numeric Control" and "Computer Numerical Command," do not align with standard terminology used in the industry. The incorrect options often mix or misinterpret technical terms commonly associated with CNC technology, but they do not represent the widely accepted and recognized definition of CNC as "Computer Numerical Control."
