Aerospace Component: Door Hinge
The structure, or fuselage, is a primary component of any aircraft, holding subsections like the cockpit, windows, doors and seating. A passenger or cargo door is connected to an aircraft fuselage by a hinge mechanism with an elongated hinge part. One end of the hinge is pivotally connected to an idler crank arm which is pivotally connected to the fuselage. The other end of the hinge is pivotaly connected to the door.
Machining Processes:
The door hinge was machined using a Fehlmann PicoMax95 5-axes machine using a HSK63 adaptor. The material block was chromium-nickel austenitic stainless steel (X6CrniTi). Main operations include trochoidal milling, slotting and side milling.
