Abstract: Systems and methods are provided for shape controlled gripping of a workpiece. A layer jamming structure includes a membrane defining an internal cavity containing a number of overlapping material layers. A pressure system includes a pump coupled with the internal cavity. A shape conforming tool includes at least one part configured to move to apply a force to the layer jamming structure. The shape conforming tool, by operation of the part, conforms the layer jamming structure to the workpiece. The pressure system, with operation of the pump, changes a pressure in the internal cavity to impart rigidity to the layer jamming structure.

Abstract: Systems and methods are provided for gripping of a workpiece with a layer jamming structure having rigid datum structures. A system includes a layer jamming structure configurable in an inactivated conformable state, with a membrane defining an internal cavity containing a number of overlapping material layers. The rigid structures engage the layer jamming structure. A pressure system includes a pump coupled with the internal cavity to change a pressure therein to transform the layer jamming structure from the inactivated conformable state to an activated rigid state disposed around the workpiece. The rigid structures help conform the layer jamming structure to the workpiece during transformation to the activated rigid state and to present datum fixturing surfaces in the activated rigid state.

Abstract: A high heat-absorption casting core for manufacturing a cast component includes a core body. The core body has at least a portion thereof defined by metal powder. The metal powder is configured to absorb heat energy from the cast component during cooling of the component and solidification thereof. The core body may be additionally defined by a sand fraction in contact with the metal powder fraction. A system and a method for manufacturing a cast component using the high heat-absorption casting core are also envisioned.

Abstract: Systems and methods are provided for locating a pair of components relative to one another using complex surfaces. One component has a complex surface, where the complex surface is smoothly contoured. Another component is shaped to be connected with the first component. A fixture locates the first component relative to the second component. The fixture includes a locator with a complex surface region shaped to mate with the complex surface of the one component to locate the fixture relative to that component. The fixture includes another locator to locate the fixture relative to the second component.

Abstract: A panel assembly is formed by a plurality of bonds between two sheet materials in a face to face relationship to form a preform. The plurality of bonds define a closed perimeter region between the two sheet materials and an open perimeter region between the two sheet materials. The preform may be formed into a predefined shape. Pressurized fluid is applied through an inlet into the open perimeter region to expand the preform. The pressurized fluid expands the open perimeter region such that the two sheet materials expand in an opposing direction, thereby defining an expanded open perimeter region. The closed perimeter region between the two sheet materials remains vacant of the pressurized fluid such that the closed perimeter region is not expanded. The expanded open perimeter region is filled with a filler material for improving a performance characteristic of the panel assembly, e.g., strength, sound absorption, or stiffness.

Abstract: A powder material for an additive manufacturing process and a method of manufacturing a three-dimensional article via an additive manufacturing process. The powder material comprises an iron-based alloy including alloying elements of carbon (C) and copper (Cu). The iron-based alloy may be formulated to achieve a precipitation strengthened microstructure comprising a lath martensite matrix phase and a Cu precipitate phase. The iron-based alloy may have a Cu weight fraction and a nickel (Ni) weight fraction, and the Ni weight fraction may be less than the Cu weight fraction of the iron-based alloy.

Abstract: A system and method for additive manufacturing are provided. The system includes a structure defining a chamber for manufacturing parts via additive manufacturing. A powder metal applicator is configured to deposit layers of powder metal material to build a part on a build platform. A laser source is configured to direct one or more laser beams onto each layer of powder metal material to fuse the powder metal material, wherein metal condensate is created by the laser beam(s) contacting the powder metal material. An element spaced apart from the layers of powder material has a temperature different than the chamber temperature, so that the element is configured to attract or repel the metal condensate by virtue of the temperature differential between the element and the chamber. The method includes using the element having the different temperature to attract or repel the metal condensate within the chamber.
