What does CNC stand for in engineering design?

CNC in engineering design stands for Computer Numerical Control. This term refers to the automated control of machining tools and 3D printers by a computer. In CNC machining, a computer program containing a list of precise movements and commands is executed, allowing for high levels of precision and repeatability in manufacturing processes.

The importance of CNC lies in its ability to produce parts with great accuracy and complexity while reducing the time and labor costs associated with traditional manufacturing methods. Through the use of CAD/CAM software, designers can create detailed designs that are automatically translated into the movements needed for the CNC machine to execute. This technology revolutionizes the manufacturing industry by enabling mass production of parts with minimal human intervention.
