CNC machining, or computer numerical control machining, is a subtractive manufacturing process that employs computer-controlled machines to remove material from a workpiece to produce a desired shape or form. CNC machines use a variety of cutting tools to shape the workpiece, following programmed instructions that specify the tool's path, speed, and depth of cut.

CNC machining offers several advantages over traditional manual machining, including:

Precision: CNC machines can achieve high levels of precision and accuracy, making them ideal for creating parts with complex geometries and tight tolerances.

Repeatability: CNC machines can produce consistent and repeatable parts, ensuring quality control and consistency in manufacturing.

Efficiency: CNC machines can operate continuously for extended periods, reducing production time and increasing productivity.

Automation: CNC machines can be programmed to perform a sequence of operations without human intervention, minimizing the need for manual labor and reducing production costs.

Versatility: CNC machines can be used to process a wide variety of materials, including metals, plastics, wood, and composites, making them suitable for various applications.

CNC machining is extensively used in industries such as aerospace, automotive, medical, and electronics, where high-precision and reliable parts are required. It enables the creation of complex components with intricate designs and tight tolerances, enhancing product performance and reducing the need for post-processing operations.
