Computer numeric control (CNC) machining is a manufacturing pr-
ocess that automatically shapes or forms metals or other materials
into highly precise parts. This is done through the manipulation of
raw materials by machine operated cutting tools.Precision CNC ma-
chining systems are equipped with a computer consisting of one or
more microprocessors and storage units. CNC machines utilize sp-
ecialized software in conjunction with CAD/CAM software systems to
instruct the tooling to execute the exact movements necessary to create the part.Precision
CNC machining is a highly automated process that requires very little attention from
workers, Operators only need to load materials, and make any adjustments to the design.
parameters.So, a CNC machining operation can run unattended for certain periods of time.
Precision machining is an efficient and quick way to precisely produce detailed parts. This
service is also known as contract servicing.

It is important to know the parameters of a machined part that is needed when utilizing CNC

machine work services. Many CNC machining service companies will create the design code
based on specifications given them. Often the CNC machining systems are able to take an
existing part and create code based on photo imaging programs. Some companies will take
a CNC file and create the parts on their machines.
 
Types
A Lathe: is a machine tool for shaping metal or other material. The material is turned
about a horizontal axis while it is shaped by a fixed tool.
CNC milling: is possibly the most common kind of CNC machining. CNC milling machines
are classified according to the number of axis points that they use.Typically these machines
have at least three axes, X and Y for horizontal movements, and Z for verticals. Some
machines however utilize five axis points with extra pivot points. Also known as CNC turning
CNC drilling: is an automatic machine process utilizing a drill to cut parts.
CNC punch machines: are machines that cut parts on computer numeric control systems.
Precision laser machining: is the precision cutting of parts with a laser using CNC
machines to control the laser to ensure accuracy.
