Abstract: A cutting tool comprises a tool body having a first end and a second end, and a longitudinal axis extending between the first end and the second end. The first end comprises two or more cutting portions, with each of the cutting portions comprising a cutting edge and a flank surface.Each cutting edge extends radially outwardly from a centre region of the first end to a perimetral edge of the first end, with the cutting edge being angled relative to the longitudinal axis. Each flank surface extends circumferentially from the cutting edge.Each of at least two of the two or more flank surfaces comprises an abrasive portion extending over at least a part of the respective flank surface and each abrasive portion comprises a plurality of abrasive features.

Abstract: 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.

Abstract: A clamping mechanism for machining a composite component. The clamping mechanism comprising two or more opposing clamping plates, each clamping plate comprising a clamping surface; and wherein each clamping surface is adaptable to follow the microstructural surface of the composite component being clamped. The clamping surface may comprise a plurality of deformable micropillars featuring a body that extends to a base on the clamping plates and a head that deforms to follow the microstructural surface of the composite component. The clamping surface in use may be an exact negative of the microstructural surface of the component clamping surface. Each clamping surface may comprise a disposable insert that replicates exclusively at the point of contact the microstructural surface of the component being clamped.

Abstract: A fluted drill comprises, in axial sequence, a body portion, and a cutting portion. The cutting portion comprises two or more cutting edges, with each cutting edge extending from a distal end of the cutting portion, along the cutting portion towards the body portion, to the body portion.Each cutting edge has a first rake angle at the distal end of the cutting portion, progressively increasing to a third rake angle at a proximal end of the cutting portion. Each cutting edge has a first uncut chip thickness at the distal end of the cutting portion, progressively decreasing to a third uncut chip thickness at the proximal end of the cutting portion.
