Definition of: CNC Milling
CNC Milling is the most common form of CNC (Computer
Numerical Control). CNC milling performs the functions of
drilling as well as turning. CNC mills are categorized
according to the number of axes.
Axes are labeled as x and y for horizontal movement, and z
for vertical movement. A standard manual light-duty mill is
typically
assumed to have four axes:
1) Table x
2) Table y
3) Table z
4) Milling Head z
CNC Milling Machines
The number of axes of a milling machine is often
interpreted in varying ways. A five-axis CNC milling machine
has an extra axis in the form of a horizontal pivot for the
milling head. This 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.
CNC milling machines are traditionally programmed using a
set of commands known as G-codes. G-codes represent specific
CNC functions in alphanumeric format.
