For an extremely basic answer, an end mill is rotated in the spindle of a milling machine and moved against a piece of material (metal or otherwise) and the rotating 'blades' on the edge of the tool will slice away material to produce the desired form or shape. Originally an end mill was used to remove material using only the cutting flutes ...
