computer numerical control

CNC Punching machines have lower capital cost than lasers and they do not use electric power to nearly the same extent (nor do they have the need for various cutting gases). It is also true that no laser machine can compete with punching in the speed of producing a large number of similar holes or slots. Equally, some jobs do not require the fine edge finish provided by laser. CNC punching can therefore sometimes offer a viable and economical alternative to laser cutting.The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. The operating parameters of the CNC can be altered via software load program.
