What is the purpose of using Computer Numerical Control (CNC) in machining?

Using Computer Numerical Control (CNC) in machining primarily aims to automate the machining process, thereby enhancing precision and consistency in operations. CNC allows machines to be operated by a computer program, which precisely controls the movements and actions of the tools involved. This automation significantly reduces the risk of human error that can occur with manual operations, ensuring that dimensions and tolerances are consistently met across numerous parts produced.

Furthermore, CNC systems can execute complex machining tasks that would be extremely difficult or impossible to perform manually. This makes it possible to produce intricate designs with high levels of repeatability, which is essential in many manufacturing scenarios where uniformity is critical. This precision extends the capabilities of manufacturers, facilitating high-volume production while maintaining quality.

Although CNC machining also contributes to reducing material waste and has some impact on simplifying the design process, its standout purpose is most strongly aligned with automation that guarantees precision and consistency throughout the machining process.
