An assembly for a dual-walled component of a gas turbine engine and methods of forming and repairing a dual-walled component. The assembly includes a cold section part having an outer surface that defines a plurality of impingement apertures, a hot section part including a pre-sintered preform, the hot section part positioned over the outer surface of the cold section part, and a plurality of support structures including the pre-sintered preform, the plurality of support structures positioned between the hot section part and the cold section part, the plurality of support structures separating the hot section part from the cold section part to define at least one cooling channel therebetween.

A machine tool provided with a tool spindle and a work table for supporting a workpiece for plastic forming on a workpiece with a tool attached to the tool spindle. The partially curved tool is has a moving mechanism to move the tool spindle relative to the workpiece, a spindle rotating motor to turn the tool spindle relative to the workpiece, a movement control unit to control the moving mechanism to move the tool along the workpiece while pressing a curved portion on the surface to be machined, and a turn control unit to control the spindle rotating motor to orient a normal line of the curved portion toward the surface of the workpiece at a reference position taken as a reference.

A method for controlling deformation and precision of a part in parallel during an additive manufacturing process includes steps of: performing additive forming and isomaterial shaping or plastic forming, and simultaneously, performing one or more members selected from a group consisting of isomaterial orthopedic process, subtractive process and finishing process in parallel at a same station, so as to achieve a one-step ultra-short process, high-precision and high-performance additive manufacturing, wherein: performing in parallel at the same station refers to simultaneously implement different processes in a same pass or different passes of different processing layers or a same processing layer when a clamping position of the part to be processed is unchanged. The method can realize the one-step high-precision and high-performance additive manufacturing which has the ultra-short process, has high processing precision, and the parts can be directly applied, so that the method has strong practical application value.

The invention relates to a device for assembling a plurality of panels of an aircraft fuselage, said device comprising at least one anvil body, comprising a surface for supporting the said plurality of panels, the said anvil body comprising at least one anvil rail mounted movably in a cavity of the anvil body and configured to move between a top position in which the upper surface of the anvil rail extends into the extension of the support surface and a bottom position in which a workspace is created between the upper surface of the anvil rail and the support surface so as to allow a machining and/or stripping tool to pass through.

An apparatus for trimming a sheet metal panel in a die set. A grinding tool including a grinding wheel driven by a rotary drive is used to grind away a shear affected zone from the trimmed edge formed by the trim steel. The grinding tool is disposed within a cavity defined by the reciprocating die and is oriented to grind away a shear affected zone as the reciprocating die moves the grinding tool into engagement with the trimmed edge.

The present subject matter illustrates a portable-arrangement for assembling a down-hole tool for usage in a well-bore. The arrangement comprises a plurality of intermodal-containers for multi-modal transportation of freight defined by a plurality of modules. The modules are adapted for perforating a received base-pipe, de-burring the perforated pipe, and facilitating assembly of a plurality of screen-units around the base-pipe to achieve a screen assembly for sand and flow control. A roller flow conveyor-module is configured for providing automated-conveyance in respect of the base pipe within and across the modules. Accordingly, the assembling cum manufacturing is achieved at a local location (i.e. onsite) in the country of oil and gas wells operations enabling delivery in shorter lead times, improved inventory management and high in country value.

The present invention relates to a coupling system for use at a spindle apparatus of a machine tool, comprising an energy transmission unit with a transmitter coil unit for the contact-free transmission of electrical energy to a receiver coil unit of a tool interface unit with an electrical load and a tool interface portion for accommodation in a tool support of a work spindle of the spindle apparatus, and a coupling interface unit having an interface body element attachable to the spindle apparatus and a second coupling element which is configured to be coupled to a first coupling element of the energy transmission unit by means of a releasable connection.
