    Abstract: Presented are hybrid fixture assemblies with integrated additive manufactured features, methods for making/using such fixtures, and manufacturing systems equipped with such fixtures. A manufacturing fixture assembly includes a fixture support frame formed, at least in part, from a first material, and a fixture support shell formed, at least in part, from a second material distinct from the first material. The support frame, which seats on/mounts to a work surface, includes a skeletal substructure with multiple male connectors projecting therefrom. The skeletal substructure contains multiple first frame walls that are removably intermeshed with multiple second frame walls in a collapsible format. The support shell includes a support surface that holds a workpiece, an interface surface that abuts the skeletal substructure, and multiple female connectors that project from the interface surface. Each female connector removably receives therein a respective male connector to thereby detachably mount the support shell to the support frame.

    IPC: B23P6/04

    CPC classification number: B23P6/04

    Abstract: A method of repairing an ultra-large single-piece cast component of a vehicle body. The method includes the steps of locating a damaged portion of the cast component, determining an extent of the damaged portion of the ultra-large cast component, defining a cut-line sectioning off the damaged portion from an undamaged portion of the ultra-large cast component, cutting along the cut-line to excise the damaged portion from the undamaged portion of the ultra-large cast component, and joining a replacement piece to the undamaged portion of the ultra-large cast component. The replacement piece is fabricated based on the original manufacturer’s geometry and dimensional data of the excised damaged portion. The undamaged portion of the ultra-large cast component remains on the vehicle body during the repair.

    Abstract: Systems and methods are provided for producing one or more powders each formed of two or more materials. The system includes a housing having an enclosure, a crucible configured to produce a melt of a first material, a droplet device configured to receive the melt of the first material and produce a flow of droplets thereof within the enclosure, a distribution device configured to propel a second material into the droplets to mix therewith, wherein the droplets solidify to form particles of the first material, the second material, and/or a reaction product thereof, a platform within the enclosure configured to intercept the particles, and one or more generators configured to produce electromagnetic waves and/or acoustic waves to form a fluidized bed of the particles on the platform. The platform and/or the one or more generators are configured to produce, from the fluidized bed, a powder including the particles.

    Abstract: A design for repair casting having a repairable ultra-large single-piece casting and a replacement part. The ultra-large single-piece casting includes a main body portion, at least one predefined replaceable portion integrally cast with the main body portion, and a cut-guide delineating the predefined replaceable portion from the main body portion. The cut-guide includes a continuous channel defined on an exterior surface of the single-piece casting. The cut-guide further includes a rib extending from a channel wall on the main body portion. A damaged replaceable portion is excisable from the main-body portion by cutting through the single-piece casting along the cut-guide. The excised damaged replaceable portion may be replaced with the replacement part, which has substantially the same geometry, dimensions, and mechanical properties as an undamaged replaceable portion. The replacement part may be joined to the main body portion by mechanical means or by welding.
