What does CNC stand for in manufacturing technology?

CNC stands for Computer Numerical Control, which relates to a manufacturing process that uses programmed computer software to automate machine tools. This technology allows for precise control of machinery and details the process of converting designs into a series of precise movements and actions that the machine can execute.

The term encompasses the automation of machine operation via programmed commands, which can be complex and intricate, resulting in high precision and repeatability in the manufacturing processes such as milling, turning, drilling, and laser cutting, among others. With CNC, operators can input detailed specifications and create intricate parts with minimal human intervention, increasing efficiency and production capabilities while reducing the likelihood of human error.

By understanding the full term, it becomes clear that it captures both the aspect of computerization and the numerical instructions that guide the manufacturing process. The distinction that "numerical" is meant rather than "numeric" in this context places emphasis on the use of numbers in a continuous and systematic manner for control purposes, signifying a more comprehensive approach to controlling machinery.
