    摘要： Die Erfindung betrifft eine Anordnung zur Wiederherstellung einer optimierten Kontur der Eintrittskanten von Gasturbinenschaufeln, bei der eine Gasturbinenschaufel (2) mit Hilfe eines computergesteuerten Roboters (10) an einer oder mehrerer Schleifmaschine(n) (71, 71') vorbeigeführt wird. Aufgrund des Nachfahrens eines in einem Datenspeicher (21) abgespeicherten Bewegungsablaufs wird die gewünschte Kontur erreicht. Der abgespeicherte Bewegungsablauf ist zur Überführung einer Schaufel aus einem vorher ermittelten statistischen mittleren Verschleißzustand in eine ebenfalls vorher ermittelte oder berechnete Designkontur ausgebildet. Der Anpressdruck der Gasturbinenschaufel an die Schleifscheibe(n) (71, 71') wird gemessen und so in dem Bewegungsablauf des Roboters (10) berücksichtigt, dass die gewünschte Designkontur unabhängig von der Ausgangskontur und Abnutzung der Schleifscheiben erreicht wird.

    摘要： The time to grind a workpiece (82) can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength consideration require, and which may therefore be less than the axial length of the region to be ground. It is especially beneficial in a grinding machine (68) to employ two narrow grinding wheels mounted for independent movement towards and away from a workpiece (82). The wheels can be applied to plunge grind axially separated regions of a cylindrical portion of a workpiece, thereby enabling the machine to grind a range of axial lengths up to a length not exceeding a sum of the two wheel widths.

    摘要： The time to grind a workpiece can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength considerations require, and which may therefore be less than the axial length of the region to be ground providing a work rest or work steady to increase the workpiece stiffness if required, and performing a succession of plunge grinding steps so as to grind the whole of the said axial region. Typically the grinding wheel is an electroplated CBN wheel, and the width of the grinding wheel selected is the narrowest permissible given the desired feed rate and motive power available. A grinding machine is disclosed comprising a wheelhead having mounted thereon a grinding wheel whose width is not substantially greater than that dictated by structural and strength requirements, programmable indexing means to enable the relative positions of the wheelhead and workpiece to be adjusted in a sequence of steps to achieve a sequence of plunge grinds, which may or may not overlap, to enable a region of the workpiece to be ground, the axial extent of which is greater than the width of the wheel, and wheel feed means and control means by which the feed rate is controlled, whereby the wheel feed rate is similarly programmable to enable a feed rate to be achieved which is limited only by the peak and RMS power capabilities of the wheel spindle drive motor, so that the rate of material removal is as high as is compatible with the power capabilities of the machine during each plunge, thereby optimising the total cycle time for grinding.
