Abstract
An electrode tool for use in a spark-erosion or electrolytic machining operation is made by providing a model 11, Fig. 3, of the article to be machined, such as a turbine blade, but differing therefrom to allow for electrical machining parameters, depositing on the model surface 13 an electrically conductive layer 15, and stripping the layer from the model whereby the interface surface forms the cathode electrode surface 13c, Fig. 8. The model 11 may be of wood, particularly balsa wood, plastic, ceramic plaster, metal or carbon; the layer 15 may be of nickel, chromium, nickel followed by copper or silver or silver followed by nickel, applied by vapour deposition, spraying, dipping or electro-plating. In one example a layer of silver is applied by spraying silver nitrate and ammonia which is reduced by formaldehyde, and the silver has a further layer of nickel applied by electroplating. During application of the layer to one surface 13 of the model, the other surface 14 may be masked with a plastic material 16. Subsequently the surface 13 is masked whilst a layer is applied to the other surface 14, Fig. 4 (not shown). A duplicate of the model may be used to receive the surface layer, Figs. 4-6 (not shown). The layer may be removed by burning or otherwise decomposing the model. The cathode electrode 20, Fig. 8, is formed by the layer 15 embedded in an insulated backing 21. Workpiece 19 to be machined is supported on pins 23 in a bath of electrolyte or dielectric liquid and the electrode is fed in the direction 28. Subsequently the workpiece is reversed and a second electrode is used to form the other surface 14, Fig. 9 (not shown). <PICT:0952719/C3/1> <PICT:0952719/C3/2> <PICT:0952719/C3/3> In another embodiment, Fig. 10, an airfoil blade 11 is formed by separate electrode portions 24a, 24b, 24c, 24d fed by pistons 28a controlled by a programming means 30. Electrolyte is circulated by a pump 29. Specification 335,003 is referred to.
