Abstract: A method of manipulating a thin-walled structure includes providing a thin-walled structure in a first unconstrained configuration, constraining the thin-walled structure to a first constrained configuration in which a first feature of the thin-walled structure is spatially located relative to the a second feature of the thin-walled structure in a predetermined manner, wherein an open volume of the thin-walled structure is constrained to maintain a predetermined open volume shape, and machining the thin-walled structure to a second constrained configuration in which the first feature of the thin-walled structure remains spatially located relative to the second feature of the thin-walled structure in the predetermined manner.
