What does CNC stand for?

CNC stands for Computer Numeric Control. This term refers to the automated control of machining tools such as drills, mills, and lathes through a computer program. In a CNC system, the computer interprets a numerical code that corresponds to precise measurements and movements needed for the machining process, enabling high levels of precision and repeatability in manufacturing.

The use of "Computer" in the term emphasizes the reliance on software and electronic systems to manage the machinery, which is a fundamental aspect that distinguishes CNC from other types of manufacturing controls. The "Numeric" part reflects the mathematical nature of the control signals that guide machine positioning and operation, whereas "Control" highlights the system's ability to direct machinery operations based on predefined parameters.

Understanding the correct term is essential for anyone involved in manufacturing, as it is a cornerstone of modern machining technology and impacts the efficiency, speed, and accuracy with which products are made.
