摘要： A system and method that includes, in an embodiment, a prism, a camera, a light source, and a plate. The system, in an embodiment, is configured for scanning a roll and generating an image of the roll surface. The prism, in an embodiment, is positioned below the camera and above the plate. In an embodiment, the plate is positioned below the prism and above the roll surface. In an embodiment, the light source is positioned above the prism. In an embodiment, the light source and the prism are positioned to provide light to the roll surface at an angle of at least 75 degrees measured from a line normal to the roll surface. In an embodiment, the prism is configured to refract light from the light source, the camera is a line scan camera that includes a row of pixel sensors, and the light source includes light emitting diodes.

摘要： Methods for creating three-dimensional volume quality models of additively manufactured metal bodies are disclosed. In one embodiment, a method comprises additively manufacturing each metal layer of a metal body. One or more images of the first metal layer are obtained. The image(s) are processed to detect and map potential manufacturing defects in the first metal layer. A two-dimensional contour of the first metal layer is generated from the three-dimensional CAD model. The mapped defects are integrated into the two-dimensional contour. A first layer of a three-dimensional volume quality model of the metal body is created based on the integrated two-dimensional contour.

摘要： Broadly, the instant disclosure is directed towards: fertilizer compositions and methods of making the same, in which, due to the composition, the fertilizer exhibits blast suppression (e.g. measured via specific impulse) and/or desensitization (e.g. measured via unconfined critical diameter and/or booster quantity needed to initiate detonation) as compared to existing ammonium nitrate fertilizer(s).

摘要： Methods for producing forged products and other worked products are disclosed. In one embodiment, a method comprises using additive manufacturing to produce a metal shaped-preform and, after the using step, forging the metal shaped-preform into a final forged product. The final forged product may optionally be annealed.

摘要： A fastener includes a sleeve, a core bolt, and an insert. The sleeve includes a first portion having a first inner diameter, a second portion having a second inner diameter, and a step intermediate the first and second portions. The core bolt includes a cylindrical portion having a first diameter, a threaded portion having a major diameter, and a thread run-out intermediate the cylindrical and threaded portions. The insert is disposed within the sleeve and is sized and shaped to be retained between the step of the sleeve and the thread run-out of the core bolt when the fastener is in a pre-installation position. The fastener compresses the insert between the step of the sleeve and the thread run-out of the core bolt by an installation motion of the core bolt. The insert deforms away from the core bolt to initiate formation of a bulb in response to the compression.

摘要： A fastener installation tool including a cylinder assembly, a handle/sleeve assembly, and a tool head. The handle/sleeve assembly includes a handle having a bore and a sleeve positioned within the bore. An inner wall of the sleeve includes a first portion with a first inner diameter and a second portion with a second inner diameter. The sleeve includes an outer wall having a first portion with a first outer diameter and a second portion with a second outer diameter, the first outer diameter of the first portion of the outer wall of the sleeve being greater than the second outer diameter of the second portion of the outer wall of the sleeve. A space is formed between the second portion of the outer wall of the sleeve and the second portion of the inner wall of the handle, which enables the sleeve to flex during operation of the tool.

摘要： A fastener adapted to be installed in a hole of a composite structure includes a sleeve, a pin member, and a locking member. The sleeve has an outer surface having an outer diameter. The outer surface of the sleeve is textured. The outer diameter of the tubular portion is less than an inner diameter of the hole of the structure. The pin member has a shank portion. The sleeve is adapted to expand radially over the shank portion of the pin member to form an interference fit between the outer surface of the sleeve and the hole of the structure so as to provide an installed position of the fastener. When the fastener is in the installed position, the texture of the outer surface of the tubular portion deforms to engage with voids of the composite material present on the inner surface of the hole.
