US Patent:

20090265923, Oct 29, 2009

Filed:

Mar 23, 2009

Appl. No.:

12/383305

Inventors:

Greg A. MaClean - Westwood NJ, US
Michael J. Spellman - Westwood NJ, US

International Classification:

B23P 19/00

US Classification:

29729

Abstract:

An electronic wire harness assembly system having a transparent pegboard with a rear mounted digital display such as an LCD or plasma display is controlled by a proprietary software program running on a personal computer. The digital display provides peg location illumination, wire run path location illumination, connector shape illumination and location illumination, as well as cable tie location illumination. The operator is visually assisted with notes and videos displayed under the pegboard at the appropriate locations. The pegboard grid is registered to the digital display with simple mouse pointer clicks.

Abstract:

A novel method designs and analyzes composite parts including optimal manufacturing strategies. The invention analyzes part design including curvatures and other surface topology to formulate an optimal strategy for material layup, number of plies, initial orientation angle, and towpath steering vectors. The method computes an optimum starting point for each fiber path and a stagger offset for each successive fiber path to as to eliminate or minimize gaps and overlaps between adjacent plies. Intermediate surfaces are generated by a polynomial discretization method which generates large computational time savings and enhances blending of adjacent zones to control surface smoothness. The method further calculates a variable steering path for the layer taking into account material parameters and limitations such that plies originating in the same location have a variable orientation angle and follow any reference curve generated by the method to maximize strength and minimize weight of the component.

Abstract:

A method and system for assisting in the manufacture of composite parts such as those used for various high-strength assemblies such as aircraft wings, vertical stabilizers, racing car shells, boat hulls, and other parts which are required to have a very high strength to weight ratio. The system uses laser technology to measure the resultant surfaces of a first manufactured composite part. A computer system analyzes and compares the as-built dimensions with the required production specifications. Supplemental composite filler plies are designed including shape and dimensions. These plies are nested together into a single composite sheet and manufactured to minimize wasted material. The plies are then cut out and applied to the first part guided by a laser projection system for locating the plies on the part. The part is then re-cured. The final assembly is then re-measured for compliance with production dimensions.
