摘要： A method for bending a tube in a pre-selected geometry includes deriving at least one processing parameter from the geometry, applying a thermal source circumferentially to the tube to heat the tube along at least one circumferentially directed path in accordance with the parameter and actively cooling the tube to a pre-selected temperature. The applying and active cooling steps are alternately performed a number of times. A system for bending the tube includes a thermal source for heating at least one region along the path on the tube, a tube advancing module for advancing the tube, an active cooling module for cooling the tube to a pre-selected temperature, a processing module to derive at least one processing parameter from the geometry and a control module configured to control the thermal source and active cooling module in accordance with the parameter. The alternate heating and cooling are performed a number of times.

摘要： A method for detecting misalignment of initially-aligned fiber filaments in a composite. An optical fiber is placed among the fiber filaments in the composite, light is directed into the optical fiber, the intensity of the light in the optical fiber is measured during subsequent composite processing, and attenuation in such light intensity is ascertained which indicates such misalignment (e.g., wrinkling, bending, buckling, porosity, delamination and the like) is being detected during such processing. In another preferred method, before-processing and after-processing x-ray images are taken of an x-ray-attenuating fiber which has been placed among x-ray-transparent fiber filaments in a composite.

摘要： A method of nesting a computer model of a part (100) into a computer model of a fixture (104) useful for situations where the original positions of the part and fixture are completely separate and for situations where the respective part and fixture surfaces overlap. The model of the fixture is first inset by a distance D sufficient to eliminate any overlap between the modeled surfaces. The minimum normal distance segment (105) between the inset fixture surface and the part surface may then be determined using standard CAD system capabilities. A vector is then constructed having a length D beginning at the minimum distance point 111 on the inset fixture surface (107) and extending in the direction of the minimum normal distance segment (105) to a point (112) on the original fixture model surface (106). The minimum distance segment between point (112) and the surface of the part (102) is then determined to identify a point (114). The respective point pair (112,114) is recorded. Similar point pairs are recorded for each degree of freedom of movement between the part and the fixture. An orthonormal transformation matrix is then identified for moving the part to a position that minimizes the aggregate distance between the respective point pairs. This process may be repeated until the aggregate distance satisfies an acceptance criteria, whereupon the part model is deemed to be nested into the fixture model.

摘要： A system and method for numerical control processing of an in-process part. A mathematical mapping is generated which approximates the deformation of the in-process part as measured against a nominal model. The mapping is applied to nominal NC tool paths to generate modified tool paths that travel in the distorted coordinate space of the in-process part. A result is that local features may be machined into the in-process parts in reasonable locations, and non contact measurement systems as well as surface finishing systems can travel at a more constant distance from the surface of the in-process part.
