Milling is as fundamental as drilling among powered metal cutting processes.
Milling is versatile for a basic machining process, but because the milling set up has so many degrees of freedom, milling is usually less accurate than turning or grinding unless especially rigid fixturing is implemented.
For manual machining, milling is essential to fabricate any object that is not axially symmetric. There is a wide range of different milling machines, ranging from manual light-duty Bridgeports to huge CNC machines for milling parts hundreds of feet long. Below is illustrated the process at the cutting area.
