Computer Numerical Control (CNC) Milling is the most common form of CNC. CNC Mills are classified according to the number of axes that they possess. Axes are labeled as x and y for horizontal movement, and z for vertical movement, as shown in this view of a manual mill table.
Normal 4 axes
Table x.
Table y.
Table z.
Milling Head z.
A five-axis CNC milling machine has an extra axis in the form of a horizontal pivot for the milling head. his allows extra flexibility for machining with the end mill at an angle with respect to the table. A six-axis CNC milling machine would have another horizontal pivot for the milling head, this time perpendicular to the fifth axis.
