Abstract: A method of machining a surface of a component. The method comprises scanning the surface of the component to obtain scanned electronic 3D data representing the scanned surface of the component locating a surface defect of the scanned surface and identifying a defect region that surrounds and includes the surface defect, and providing electronic 3D data representing a patch having the desired shape of the defect region. The method also comprises transforming the patch to generate a tooling path for repairing the surface defect. The transformation comprising translating a plurality of nodes of the patch. The translation distance of each node based on the distance of that node from an origin node of the patch. The method further comprises machining the surface of the component according to the generated tooling path.

Abstract: There is disclosed a blade for a gas turbine engine comprising a blade root that is elongate in a longitudinal direction. The blade root comprises a first flank surface and a second flank surface on opposite sides of the blade root that are asymmetrical about a longitudinal mid-plane of the blade root.

Abstract: This disclosure concerns an adaptive repair method, for example for aerofoil blade components. The method generates a digitized model of a physical component and uses data from the digitized model to align a part of the physical component with a nominal CAD model of the component. A combination of the digitized data and data from the nominal CAD model are then used to create an adapted model for repair of the component.

Abstract: This disclosure concerns an adaptive repair method, for example for aerofoil blade components. The method generates a digitised model of a physical component and uses data from the digitised model to align a part of the physical component with a nominal CAD model of the component. A combination of the digitised data and data from the nominal CAD model are then used to create an adapted model for repair of the component.

Abstract: Apparatus for enabling determination of position of an object, the apparatus comprising: a baseplate configured to support a fixture for retaining the object, the base plate comprising: a body comprising: a first connector configured to connect to a second connector of the fixture; and a plurality of first reference marks distributed on at least a first surface of the body.
