  • Patent number: 10618120
    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.

  • Patent number: 8568197
    Abstract: A pocket (6) is machined into the surface of a component (9) by pressurising a fluid (1) and directing a jet (11) of the pressurized fluid (1) at the surface to be machined. Continuous relative movement is provided between the component (9) and the pressurized jet (11) of fluid (1) during machining. Material is removed from the component (9) in a series of layers, whereby the path of the fluid jet (11) in one of the layers is perpendicular to the path of the fluid jet (11) in the subsequent layer. The fluid jet (11) operates continuously until the required amount of material has been removed from the component (9).

  • Publication number: 20110194906
    Abstract: A machine tool has a tool holder mounted to a platform, and a plurality of legs for connecting the platform to a workpiece. Each leg has joint systems which allow each leg to rotate relative to the platform and the workpiece and are also actuatable to alter the inter-joint distance. By alterations in the inter-joint distances of the legs the position and orientation of the tool holder relative to the workpiece is controllable. Each leg also has an attachment foot for removably attaching the leg to the workpiece. The provision of separate attachment feet avoids the need for a dedicated base for the machine tool so that it can be used in-situ and in confined and obstructed working environments.
