Milling Machine: Methods of Milling. Milling Processes ...
Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

Is 3D an environmental win? | Greenbiz
These "points" are a way to compare the apples and oranges of different environmental impacts. Most LCAs of these machines only measure energy use, but that's not enough. For our high-usage scenarios, if we measured only energy use, the milling machine would score the best. But if we measured only waste, the mill would score the worst.
