1. A method of manufacturing a jointed device, comprising the following steps:
(A) providing a machining fixture and an electrical discharge wire, said machining fixture comprising a plurality of member holes, each of the plurality of member holes being adapted to accommodate at least one workpiece, said at least one workpiece being adapted to form at least one portion of said jointed device;
(B) providing at least two workpieces, comprising a first workpiece and a second workpiece, accommodated within at least two member holes of said plurality of member holes;
(C) associating said machining fixture to the electrical discharge wire so that said electrical discharge wire can cut at most one of said at least two workpieces at a time;
(D) cutting said at most one of said at least two workpieces by said electrical discharge wire;
(E) after step (D), rotating the machining fixture around a fixture rotation axis of a predetermined fixture rotation angle, said predetermined fixture rotation angle being chosen to provide that said electrical discharge wire can cut said at most one of said at least two workpieces at a time;
(F) after step (E), cutting said at most one of said at least two workpieces by said electrical discharge wire.
