Abstract:
Es wird ein automatisches System zum Flicken von Flächen mit natürlicher Musterung, insbesondere von Holzpaneelen beschrieben, bei welchem nach dem automatischen Erkennen und Flicken der Fehlstellen durch Spachteln oder Dübeln die störend sichtbaren Flickstellen durch einen numerisch gesteuerten Dekorationsprozess, insbesondere ein Tintenstrahl-Drucktechnologie lokal dekoriert werden. Hierbei wird das Paneel zusätzlich zu dem für die Erkennung der Fehlstellen geeigneten Bildgeber von einem insbesondere farbtüchtigen Abtaster bildhaft erfasst. Aus den globalen Färb- und Strukturmerkmale des Paneels sowie den lokalen Färb- und Strukturmerkmale jeder individuellen Fehlerregion werden automatisch aufzubringende lokale Dekorationsmuster abgeleitet, welche die Fehlstellen als solche nicht mehr sichtbar werden lassen und sowohl lokal als auch global dem Paneel ein gewünschtes ästhetisches Aussehen verleihen.
Abstract:
The present disclosure addresses limitations with methods, systems and processes for integrating multiple advanced technologies into a single automated manufacturing and repair cell. The methods, systems and processes of the present disclosure leverage unique software and hardware to configure a manufacturing cell that is capable of conducting process development and planning, dimensional analysis, pre-machining, surface preparation, cold spray (supersonic particle deposition), dust collection, helium recovery, and post machining in a single integrated manufacturing and repair cell.
Abstract:
The profile of an aerofoil blade is measured through centre line determination. Curves are fitted using a best-fit alogorithm separately to measured points on both sides of the blade. An intersection point of the curves defines the leading edge point, which is used in determining the centre line. The profile of the blade is determined with reference to the centre line.
Abstract:
An apparatus for recutting the surface of a wheel is described. The apparatus comprises a rotatable mount, for holding and rotating the wheel about i ts axis, a surface profiler, operable during rotation of the wheel to detect surface elevations at different radial positions on the wheel, a surface elevation profile generator, operable to generate a surface elevation profile of at least a portion of the surface of the wheel from the detected surface elevations, a cutting profile generator, operable to calculate a cutting profile for the wheel from the surface elevation profile, the cutting profile defining a cutting elevation with respect to radial position, a cutting tool, and cutting control circuitry, operable to control the position of the cutting tool with respect to the wheel to recut the surface of the wheel in accordance with the generated cutting profile. By profiling the wheel while it is rotating, the time required to profile a desired portion of the wheel can be reduced.
Abstract:
A system is disclosed including a three-dimensional object having a non- conforming region, and a photogrammetry device adapted to scan the three- dimensional object. The system further includes optical reference targets and a controller structured to perform functions of repairing the three-dimensional object. The controller commands the photogrammetry device to scan the three-dimensional object, and calculates a nominal surface location and contour for the three-dimensional object. The controller further commands the photogrammetry device to scan the non- conforming region of the three-dimensional object, and calculates a material removal tool path comprising a path adapted to remove material from the object located beyond the nominal surface location and contour. The controller generates a solid model of the damaged region of the object based on the nominal surface location and contour, and computes a material addition tool path according to the solid model.

Abstract:
The present invention provides a method and system for automated repair of a machine component (1). According to the proposed method, a first geometry of said component (1), including a damaged portion (12) of the component (1), is digitalized (102). A trough (20) is then machined (104) over said damaged portion (12) of said component (1). The machining (102) is numerically controlled using digitalized geometrical data (207) of said first geometry of the component (1). A second geometry of said component (1) is then digitalized subsequent to said machining (102), said second geometry including said trough (20). Subsequently, a material is deposited (108) over said trough (20). The deposition (108) of the material (25) is numerically controlled digitalized geometrical data (208) of said second geometry of said component (1).
