CNC is good at making small numbers of compicated shapes. In fact, they are just the thing to make the molds (called tools and dies) to do your forging in. (As a result, CNC technology has in fact lowered the "tooling" costs associated with forging!) It got its biggest boost from the missle folks. If you only plan to build 30 of something, CNC is just the thing for parts with a complicated shape, like that landing gear strut on that fighter.
2D & 3D milling operations are made with speed and accuracy. We use Esprit (CAM) & Solid Works (CAD) software to compliment our CNC Milling Dept.
