|Computer Numerical Control (CNC) Milling is the most common form of CNC.|
CNC mills can perform
the functions of drilling and often turning. 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. A standard manual light-duty mill is typically assumed
to have four axes:The number of axes of a milling machine is a common subject of casual "shop talk" and is often interpreted in varying ways. We present here what we have seen typically presented by manufacturers. A five-axis CNC milling machine has an extra axis in the form of a horizontal pivot for the milling head, as shown below.
This allows extra flexibility for machining with the end mill at an angle
with respect to the table.
Asix-axis CNC milling machine would have another horizontal pivot for
the milling head, this time perpendicular to the fifth axis.
CNC milling machines are traditionally programmed using a set of
commands known as G-codes represent specific CNC functions in
