The first
Numerical Control (NC) machines were built in 1940’s & 1950’s that operates
through numerically encoded programs. They were then transformed into analog
& digital computers named Computer Numerical Control (CNC) Machines.
There are
several uses of these machines like Cutting, Welding or Shaping. The most
common type of these machines is known as Plasma
CNC Cutting Machine, used for cutting different parts or objects. These CNC
Cutting Machines performs every task commanded by Computer Aided Design (CAD)
& Computer Aided Manufacturing (CAM) programs encoded in their storage
devices.
The machine cuts every part automatically in accordance with the
design & manufacturing commands so as to assure the accuracy of all the
parts. Each part produced by CNC cutting machine is as original as CAD. Today
almost every major manufacturing company uses these machines as they are very
efficient & cost effective. A single CNC cutting machine performs the task
of atleast 5-10 workers hence also reducing labor cost requiring only 1 person
to supervise the process. Its accuracy is so efficient that even a microscopic
design can be repeated as many times as required. This is the reason why CNC
Cutting Machines are so popular & becoming more & more advanced in
accordance with the modernized needs of the business world.
