CNC (Computer Numerical Control) machining is a manufacturing process in which pre-programmed computer software dictates the movement of tools and machinery. This technology allows for high-precision cutting, drilling, and shaping of materials such as metals, plastics, and wood.

The CNC machining process begins with a CAD (Computer-Aided Design) model of the part to be manufactured. This model is then translated into a series of commands using CAM (Computer-Aided Manufacturing) software. The CNC machine follows these commands to execute precise movements, ensuring accuracy and consistency.

CNC machining is widely used in industries such as aerospace, automotive, medical, and electronics due to its ability to produce complex geometries with tight tolerances. The process has revolutionized traditional manufacturing by reducing labor costs, improving efficiency, and minimizing material waste.
