CNC milling is a subtractive manufacturing process used in 3D printing to create 3D parts and components from a variety of materials such as plastics, metals, and composites. The process involves removing material from a block or sheet of material using a computer-controlled milling machine.
The CNC milling machine uses a series of cutting tools to remove material from the workpiece according to a pre-programmed design. This allows for the creation of complex geometries and shapes with high precision and accuracy.
CNC milling is particularly useful for creating high-strength parts and components, as well as those that require tight tolerances and a smooth surface finish. It is often used in the production of functional prototypes, molds, and tooling.
CNC milling can also be used in combination with 3D printing, where the 3D printed part is used as a starting point for further machining and finishing. This allows for the creation of parts with intricate details and features that are difficult to achieve with 3D printing alone.
