Abstract: Disclosed is a method of producing an object, the method comprising: providing a workpiece comprising a plurality of attachment features for attaching the workpiece to a machining fixture; determining a datum, the datum being dependent upon the relative positions of the attachment features; measuring the surface of the workpiece with respect to the datum; providing the machining fixture; attaching, using the attachment features, the workpiece to the machining fixture; providing a digital model specifying the object including the attachment features; and, thereafter, using the measurements of the workpiece surface and the digital model, controlling machining apparatus with respect to the datum to machine the workpiece so as to produce the object as specified by the digital model.

Abstract: Disclosed is a method of producing a machining fixture for fixedly holding a workpiece during machining of that workpiece. The method comprises: providing an initial machining fixture comprising a plurality of receiving elements for receiving the workpiece to be machined; determining a datum, the datum being dependent upon the relative positions of the receiving elements; determining positions and orientations of one or more reference surfaces 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, thereby producing the machining fixture.
