ABSTRACT:
A method of and apparatus for electroerosively machining a desired contour in a workpiece with a wire electrode transported from a supply to a takeup and, in a path therebetween, supported by a pair of wire guide heads to tightly stretch the axially advancing wire electrode across the workpiece. On at least one side of the two opposite surfaces of the workpiece traversed by the wire electrode there is disposed a template blank secured to the workpiece and having a contour shaped to correspond to the desired contour to be machined in the workpiece for holding the axially advancing wire electrode on the surface of the template contour between the wire guide heads across the workpiece. At least one of the wire guide heads is movable and displaced to cause the machining wire electrode to move transversely to the axis thereof along the contour of the template block so that with the transverse movement of the wire electrode, the desired contour is progressively formed in the workpiece by electroerosion.
