What does CNC stand for in manufacturing processes?

CNC stands for Computer Numerical Control. This term refers to the automated control of machining tools such as drills, mills, lathes, and 3D printers through computer systems. In CNC machining, the computer receives a design file, typically created in a CAD (Computer-Aided Design) program, and translates this design into precise movements of the tools. This allows for high accuracy and consistency in producing parts and components.

The use of 'Nnumerical' is central to the concept, as it refers to the process of controlling machines based on numerical values that dictate their motions. This includes aspects such as the speed, position, and path taken by the tools, all determined by programmed numerical codes. By utilizing computer technology, CNC enhances productivity and allows for complex shapes and intricate designs that would be challenging to achieve through manual operation.
