Disclosed is a method of producing a machining fixture (40) for fixedly holding a workpiece (50) during machining of that workpiece (50). The method comprises: providing an initial machining fixture comprising a plurality of receiving elements (42) for receiving the workpiece (50) to be machined; determining a datum, the datum being dependent upon the relative positions of the receiving elements (42); determining positions and orientations of one or more reference surfaces (44a-c) with respect to the datum; measuring the surface of the initial machining fixture with respect to the datum; and, thereafter, controlling machining apparatus with respect to the datum to machine the initial machining fixture to form the one or more reference surfaces (44a-c), thereby producing the machining fixture. |
