US Classification:

72 57, 72413, 72 38, 723421

Abstract:

A die and a stationary member of resilient gas permeable composition are adapted to receive between them a three-dimensional honeycomb core article. The die includes an array of elongated mutually parallel translating pins, each terminating at a tip end and arranged in a matrix for longitudinal movement between retracted and extended positions. The stationary member includes a receiving surface facing and laterally coextensive with the tip ends of the translating pins. The tip ends are engageable with first end surface of the article, the receiveing surface of the stationary member being engageable with a second end surface of the article. The die includes a housing movably mounting the translating pins, drive output shafts drivingly connected with each associated translating pin, a transmission for independent driving controllable interconnection of each translating pin, and a selectively energizable controller interconnecting each transmission to thereby achieve selective rotation of at least one translating pin. Each translating pin may be hollow and have planar sides which prevents its rotation by the restraining action of adjacent translating pins. A controller individually moves the translating pins in a coordinated manner into engagement with the first end surface to thereby impart a desired contour while simultaneously urging the second end surface of the honeycomb core article into engagement with the receiveing surface of the stationary member producing a contour substantially similar to the first end surface.

US Classification:

356601, 356603, 356606, 356614, 356622

Abstract:

A method and apparatus for using a plurality of regions of colored light to index and locate discrete targets in photogrammetry systems. The colored regions of light are used to determine a unique location on the surface of a three-dimensional object. Multiple projections of colored regions may be used to determine precise locations on the surface of the object. Each colored region may be assigned a color-numeric identified to assist in the indexing process. The process is suitable for determining the shape of aircraft, watercraft and automotive parts.

International Classification:

G01B 11/16

US Classification:

73800, 356 355

Abstract:

A method of measuring strain in a test specimen comprises the steps of placing a pattern of marks on a surface of the test specimen, wherein the pattern of marks includes a plurality of target marks and a plurality of sets of coded marks, using the sets of coded marks to identify locations of at least two of the target marks, and using a change in distance between at least two of the marks to determine strain in the test specimen.

International Classification:

G01N 19/08

US Classification:

73104

Abstract:

A method of inspecting a specimen under test may comprise the step of disposing melted thermoplastic media onto a surface under test of the specimen under test, maintaining a constant temperature of the specimen under test at or about room temperature wherein the temperature of the specimen under test is initially lower than the temperature of the melted thermoplastic media, hardening the melted thermoplastic media to produce a replica with imperfections molded into a mating surface of the replica, and inspecting the mating surface of the replica for unsatisfactory or satisfactory imperfections in the specimen under test.

US Classification:

29 9001, 72324, 72325, 408 22

Abstract:

A device and a method are provided to allow a user to ream a hole to an accurate final diameter as desired, and at the same time, to cold work the hole to induce a beneficial residual stress that will enhance the life of the component by retarding the onset and growth of fatigue cracks in the hole. The basic design of the device has an elongated body having a forward end portion to extend through a hole to be reamed and cold worked, a reamer section formed on the circumference of the forward end portion to enlarge the hole, and a burnishing section formed on the circumference of the elongated body adjacent to the reamer. The burnishing section is operative to upset the material around the hole, so as to result in a residual stress beneficial to the hole. The reamer section is in the form of a plurality of cutting edges extending from a tip of the elongated body, while the burnishing section is also in the form of a plurality of cutting edges adjacent to the reamer section along the elongate body. The cutting edges of the reamer sections are parallel straight cutting edges or helical cutting edges.

International Classification:

G06F 19/00
G01L 1/00

US Classification:

702 42

Abstract:

A method of detecting cracks in an object includes: capturing a first image of a pattern of marks in a region of interest on a surface of the object; constructing a finite element model of the region of interest having nodes corresponding to the marks in the pattern; subjecting the object to a first mechanical load to produce strains in the object; capturing a second image of the pattern; computing strains in the object based on relative changes in locations of the marks in the first and second images; modifying the finite element model to produce a crack versus surface strain map; capturing a third image of the pattern; and comparing the locations of marks in the third image to the crack versus surface strain map to identify a crack in the object. An apparatus that performs the method is also provided.

Abstract:

Tooling apparatus comprises opposing first and second dies adapted to receive a three-dimensional honeycomb core article therebetween and including opposedly aligned arrays of elongated mutually parallel translating pins, each terminating at a tip end and arranged in a matrix for longitudinal movement between a retracted position and an extended position engageable with the article. A controller individually moves each of the translating pins in a coordinated manner between the retracted and extended positions and into engagement with the article to form it to a predetermined contour. Each die includes a housing on which the translating pins are movably mounted, a plurality of drive output shafts each drivingly connected with an associated translating pin, and a transmission disposed in the base for independent driving controllable interconnection of each translating pin with a rotational drive source, and a controller interconnecting each transmission for selective energization thereof to thereby achieve selective rotation of at least one of the translating pins. The translating pins may have planar sides which prevent their rotation by the restraining action of adjacent translating pins. Each of the translating pins may define an internal cavity extending between bottom and tip ends, each being perforated and the apparatus may include a pump for delivering temperature controlled gas to each hollow pin tube for flow through the perforations in the bottom end, through the internal cavity, and out through the perforations in the tip end for delivery to cells of the article.
