The present invention relates to a process of producing a boom part from a sheet metal blank, in particular a process of producing a boom part having a bearing seat, in which the starting material is merely formed by bending. Thus, the production process is simplified. In addition, the present invention relates to a process of producing a boom that is closed at both ends by joining two boom parts produced by means of the process of the present invention. Furthermore, the present invention comprises boom parts and booms which are produced by means of one of the processes according to the present invention.

A stemming system includes a computing device and a stemming device. The computing device includes data processing hardware and memory hardware in communication with the data processing hardware. The data processing hardware includes a transmitter and a receiver. The stemming device is communicatively-coupled to the computing device. The stemming device includes a base portion and a valve-engaging portion. The valve-engaging portion includes a transducer that obtains a measurement communicated to the receiver of the computing device. The measurement includes at least one physical parameter associated with installing a tire-wheel assembly valve to a wheel throughout a process of disposing the valve within a valve hole of the wheel. The processor analyzes a data signature associated with the measurement for determining if the valve has been adequately or inadequately installed by the stemming device.

A frame splining system for fitting substrate to a frame comprises a splining head that translates in three dimensions and rotates around a vertical axis. The splining head comprises a positioning wheel that translates ahead of a pressing wheel along a track of the frame to seat a spline in the track. A substrate cutting wheel runs ahead of the pressing wheel on an outer edge of the frame.

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.
