<p>A method and apparatus for transferring a workpiece, such as a large wind turbine component, in datum alignment between tools during a manufacturing process is described. The workpiece is transferred from a first tool to a second tool, and the method comprises arranging a support structure in datum registration with the first tool; attaching the workpiece to the support structure; releasing the workpiece from the first tool; arranging the support structure in datum registration with the second tool and such that the workpiece is supported by the second tool; and releasing the workpiece from the support structure. Arranging the support structure in datum registration with the first and second tools ensures correct alignment of the workpiece with respect to the second tool. The invention eliminates the requirement to provide datum features on the workpiece itself. In preferred examples, the workpiece is attached to the support structure by means of vacuum.</p> |
