Abstract:
A method of processing a surface in additive manufacturing comprising assembling a structure (1) for a component (10) by additive manufacturing out of a bed of a powdery base material (2), such that the structure is provided with an internal surface (4) and a powdery base material (2) covers at least a part of the internal surface (4), and actuating the base material (2) relatively to the structure (1) such that the internal surface (4) is mechanically processed by the base material (2). Further, an accordingly manufactured component and an apparatus are described.
Abstract:
A sleeve may be configured to secure an airfoil cluster for polishing. The sleeve may include a mock airfoil and a bypass flow path between the mock airfoil and an end wall of the sleeve. The sleeve may be positioned in an annular ring of sleeves in a polishing apparatus. The polishing apparatus may comprise an annular flow path for an abrasive fluid. The abrasive fluid may be flowed through the annular ring of sleeves in order to polish the airfoil cluster.
Abstract:
A tool for use during the abrasive flow polishing of an airfoil cluster in an abrasive flow machine is described. The tool may comprise a body and prongs extending from the body. Each prong of the tool may be configured to insert between an adjacent pair of airfoils of the airfoil cluster to create at least one channel therebetween. The channel may allow the flow of an abrasive media therethrough.
Abstract:
A machine for the flow finishing of mechanical pieces comprising a rotary vat for containing finishing media and a unit for moving pieces comprising at least one mechanical arm for moving the pieces being machined, said mechanical arm being associated to means for rotating the pieces within the rotary vat, said rotary vat being characterised in that it comprises at least two separate sections formed by concentric circular crowns.
Abstract:
The present invention relates to a knee joint prosthesis (1) having: a tibial component (2) and a femoral component (3). The tibial component (2) includes a fixation portion (10) adapted to be fixed to an upper end of a prepared tibia (T) in a patient, and a ceramic bearing portion (30) presenting at least one articulation surface (32). The femoral component (3) is adapted to be fixed to a lower end of a prepared femur (F) in a patient, and comprises a ceramic body portion (50) presenting at least one articulation surface (56) for engagement with the respective articulation surface(s) of the tibial component (2). The articulation surfaces (32, 56) of the tibial and femoral components (2, 3) are configured for essentially congruent engagement over a full range of movement of the prosthesis, and the bearing portion (30) of the tibial component (2) is adapted for movement relative to the fixation portion (10). The invention also provides a method of finishing articulation surfaces (32, 56) of ceramic components of a knee joint prosthesis, including the steps of combining the ceramic bearing portion (30) and the ceramic body portion (50) such that respective articulation surfaces (32, 56) are brought into engagement with a working substance (S) provided between them; and imparting relative movement to the bearing portion (30) and/or the body portion (50) such that the articulation surfaces (32, 56) repeatedly slide over one another, whereby friction forces generated between the articulation surfaces (32, 56) and the working substance (S) act to finish the surfaces simultaneously.
Abstract:
Beschrieben wird ein Verfahren sowie eine Vorrichtung zur Feinbearbeitung eines über wenigstens eine Funktionsfläche verfügenden Werkstücks vorzugsweise im Wege eines Gleitspanvorganges, bei dem das Werkstück in einen Schleifkörper oder Schleifmittel enthaltenden Arbeitsbehälter unter Ausübung einer Relativbewegung zu den Schleifpartikeln geführt wird. Die Erfindung zeichnet sich durch folgende Verfahrensschritte aus: Bereitstellen eines die Oberflächenform der wenigstens einen Funktionsfläche beschreibenden numerischen Datensatzes, Ermitteln einer die Relativbewegung des Werkstücks zu den Schleifpartikeln im Arbeitsbehälter beschreibenden Bewegungstrajektorie unter Berücksichtigung einer auf die wenigstens eine Funktionsfläche im bestimmungsgemäßen Gebrauch des Werkstückes einwirkenden Beanspruchungskollektivs, und Relativbewegen des Werkstücks zu den Schleifpartikeln im Arbeitsbehälter unter Zugrundelegen der ermittelten Bewegungstrajektorie.
