Initially, the Delcam team expected to machine the manifold parts on a five-axis machining center. The choice later switched to a multitasking turn-mill machine. Either way, a machine tool capable of complex motion was in order—specifically, a machine capable of machining various faces of the part in one setup. Because the part is so close to complete after the additive build, it is tempting to think that a simple machine tool can perform the needed machining—and maybe it can. However, additive manufacturing by its nature is employed to produce complex parts. (The ability to do so is its strength.) That means the workpiece produced in an additive process is likely to require either elaborate fixturing to hold it on a simple machine, or else a machine that is able to maneuver the tool to many positions around its complex geometry.
