    Abstract: A method of assembling a structure in aircraft or spacecraft production wherein two components to be joined together at a joint are provided, each component comprising a joining region. Sealant is applied to one of the component joining regions. An arrangement is formed by positioning the components relative to each other, whereby an uncured layer of the sealant is formed between associated joining regions. The associated joining regions are clamped against each other using a clamping device, and a clamped state is maintained until the layer of sealant has cured to a pre-defined degree, the clamping device being installable on and transportable along with the arrangement. After the layer of sealant has cured to the pre-defined degree, drilling at a plurality of fastening positions is performed to obtain a hole of final dimension at each fastening position, and installation of a final fastener at each fastening position is performed.

    Abstract: The invention relates to a replacement device (1) for replacing machining inserts (900) on a tool (800) comprising a body (810) and a head (820) carrying at least one machining insert (900), each insert being held on the head (820) by a screw. The device (1) comprises: a positioner (50) including a holder element (59) suitable for holding the body (810) of the tool; a screwdriver station with a screw gun (60) suitable for tightening and loosening the screws, the positioner (50) being suitable for moving the tool relative to the screwdriver station; a grip device (70) suitable for picking up and putting down an insert (900); a conveyor (500) having a plurality of receptacles (510) for inserts, and having distributed along it a first station (100) with the grip device (70), a second station (200) with a turning mechanism (20) for turning the inserts around, a third station (300) with an unloading mechanism (30) for unloading the inserts, and a fourth station (400) with an insert feed mechanism (40); a transport mechanism (80) suitable for moving the grip device (70) between the positioner (50) and the first station (100) of the conveyor (500); and a control center (600) suitable for automatically controlling one or more of the mechanisms and devices and/or the conveyor of the replacement device (1).
