CNC milling machines are used for the shaping of metal and other solid material and there isn’t much nowadays that hasn’t involved CNC machining somewhere in the manufacturing process. Cars, aeroplanes, machine parts, moulds for household machines, toys and prosthetics etc. are all likely to have CNC machined components.
Early milling machines were manually or mechanically operated but developed to be CNC controlled – Computer Numerically Controlled. Computer programmes control and drive the machining centre, with help from an operator and they have now also moved on from 3 axis to 4 and 5 axis machines enabling much more intricate parts to be produced.
