Milling is a machining process that involves removing material from a workpiece to shape it into a desired form. This is typically done using a rotating cutting tool, known as a milling cutter, which moves across the surface of the material. The process can be used on various materials, including metals, plastics, and wood, making it versatile for different applications. There are several types of milling operations, such as face milling and end milling, each serving specific purposes. CNC milling (Computer Numerical Control milling) has become popular, allowing for precise control and automation in the milling process, enhancing efficiency and accuracy in manufacturing.
