ABSTRACT:
The invention relates to a method of manufacturing a wobble die (9) for shaping the internal contour or the external contour of a workpiece (4) in a wobble process. Thereby a wobble movement is initially selected. The three-dimensional geometry of the workpiece (4) is described. From the three-dimensional geometry of the workpiece (4) there is prescribed a virtual die (5), the shape of which corresponds in substance to the negative geometry of the workpiece (4). The virtual die (5) is deformed, taking into account the parameters of the selected wobble movement, to a geometry describing the wobble die (9). Finally, a wobble die (9) is produced on the basis of the geometry obtained in the preceding step.
