CNC milling is a cutting process in which material is removed from a block by a rotating tool. In CNC milling the cutting tool is moved in all three dimensions to achieve the desired part shape. In CNC milling the cutting tool usually rotates about an axis that is perpendicular to the table that holds the material to be cut. A milling machine looks somewhat like a drill press at first glance. A cutting tool protrudes down from a rotating spindle. A block of material is placed on a moving table below the cutter. While the cutting tool turns, a computer controls the vertical (Z axis) motion of the cutter and the horizontal (X and Y axis) motion of the block of material. The cutter is guided to move through the material, removing portions to create shapes.

CNC Milling parts can be turned to various orientations in the middle of the process and cutting tools of various shapes can be used. Material is usually removed by both the end and the side of the cutting tool. Some common cutter shapes include:

Plain endmill - used for most milling - creates walls with straight 90 deg edges and sharp corners at the bottom of recesses.
Chamfer endmill - creates 45 deg bevels on the top edge of a wall or recess
Grooving endmill - creates rectangular grooves in side walls
Ball mill - creates rounded edges at the bottom edge of a recess
Rounding endmill - creates rounded edges at the top edge
Angle endmill - creates walls at angles other than 90 deg
