Milling: Milling, CNC milling, or manual milling is the process used to produce prismatic components. A rotating cylindrical cutter with multiple flutes, commonly called an endmill, traverses along multiple axes to machine features such as slots, pockets and profiles. A machine tool used to perform milling is called a milling machine or the CNC version is often referred to as a machining center. Milling can be performed manually or under CNC control called CNC milling. Milling and CNC milling are performed by machine shops.
