A roller assembly for a rotary dresser comprise a plurality of axial segments which may be in the form of discs, each disc provided with an abrasive, radially outer surface. The discs are secured in axial alignment, each in a preconfigured rotational orientation. The disc assembly has a centrally arranged aperture for receiving a rotor shaft. The abrasive surface of the assembly can be accurately presented as an array of uniformly shaped abrasive units in a predefined pattern.

Abrading tool for a rotary dresser

A repair method for repairing a component () of a gas turbine engine (). The method comprises first and second steps. The first step comprises directing an energy beam toward the component () to ablate a first region () of material to form a gap extending through the component () between a repair region () a base region () of the component, wherein subsequent to the first step the repair region () and base region () are joined by a connecting portion (). In the second step, an energy beam is direct toward the component () to ablate the repair region () to remove the repair region () from the component ().

Material removal method

A flexible tool comprises stiffening means switchable in use from a first state of relatively low stiffness to a second state of relatively high stiffness, and subsequently switchable from the second state back to the first state.

An abrasive element comprises a body of crystalline abrasive material. The body has an array of cutting elements formed of crystalline abrasive material which projects from a surface of the body. The shape, size and form of the projections is controlled in the production process. The body may be a natural or synthetic crystal. The body may be a film formed by deposition. The body may be diamond or cubic boron nitride. The body may be monocrystalline or polycrystalline. The projections may be aligned along a crystallographic plane or planes.
