Abstract: A portable device for shaping an edge of an aerofoil comprises a housing, a cutting tool mounted in the housing (the cutting tool having a cutting edge to remove material from the edge) and a plurality of guides mounted in the housing, so that in use the aerofoil engages with the guides to locate the edge of the aerofoil relative to the cutting edge and to permit movement of the housing in a cutting direction so as to remove material from the edge of the aerofoil. The device is characterised in that the cutting tool is mounted so that in use the cutting edge can move relative to the edge of the aerofoil in a direction generally perpendicular to the cutting direction.

Abstract: An attrition liner machining tool, configured to machine the surface of an attrition liner provided radially outward of a set of a plurality of fan blades in a gas turbine engine. The tool includes at least one rotating machine tool having a connector at a first end and a cutter at a second end. The connector is configured to rigidly connect to a rotating fan blade mount of the gas turbine engine that, in use of the gas turbine engine, supports the fan blades. The cutter is configured to machine the attrition liner. The at least one rotating machine tool is configured such that, when it is connected to said rotating fan blade mount of a gas turbine engine, the cutter is passed across the surface of the attrition liner when said rotating fan blade mount is rotated.
