    Abstract: Non-circular holes are formed by electrochemical machining with an electrode that includes a hollow shank having a circular cross-section and a hollow tip section having a non-circular cross-section disposed on one end of the shank. The tip section is very small in length relative to the shank such that the shank comprises a large majority of the electrode's overall length. Because the majority of the electrode is circular in cross-section, it is relatively easy to straighten the electrode prior to a machining operation and to keep it straight during the operation, thereby overcoming problems experienced with full-length, non-circular electrodes. The circular shank also avoids electrolyte pressure imbalances and eases the difficulty and high cost of manufacturing electrodes capable of forming non-circular holes.

    Abstract: An electrochemical machining process is disclosed for forming multiple raised areas having multiple heights in a wall of predrilled holes within a workpiece. Positioned within each hole is an electrode coated with an insulating material in a pattern defining the raised areas to be formed in the wall of each respective hole. An electric current is applied from a power supply to each of the electrodes. A resistor is positioned between the power supply and at least one of the electrodes to vary the voltage passing through the electrode to vary the amount of material removed within that respective hole.

    Abstract: A process is set forth for electrochemically machining holes in a workpiece, such as a die, in such a manner so as to virtually eliminate surface finish patterns normally introduced by the electrochemical machining process, by randomly forming sequences of patterns of holes extending in rows across the workpiece along its extent, and then rotating the workpiece 180.degree. and randomly forming additional sequences of patterns of holes across the workpiece adjacent those sequences of holes which were formed prior to rotating the workpiece 180.degree..

    Abstract: An electrolytic precision drilling process for making one or more holes in a workpiece, the axis of which hole exhibits an inclination of between 2.degree. to 20.degree. relative to the surface of the workpiece, by means of at least one tubular electrode through which a stream of an electrolyte is directed onto the workpiece, comprising positioning a guide member during the drilling for sealing the gap between the guide member and the surface of the workpiece adjacent to the hole or holes, such that a surface of the guide member forms an angular space with the surface of the workpiece, the aperture angle of the angular space being twice the angle of inclination of the electrode relative to the surface of the workpiece, and the apex of which is in the area of a sharp upper edge of each hole. If one hole is drilled in this manner, the conical angular space is formed. If there are more holes, the angular space is substantially wedge-shaped, and in this case the guide member is preferably prismatic.

    Abstract: Electro-chemical drilling of small diameter holes is achieved by placing an electrolyte discharge nozzle in fixed spaced apart relationship with a workpiece, heating the electrolyte passing between the discharge nozzle and the workpiece to increase the current conductivity of the electrolyte up to about 70.degree. C and forcing a jet of electrolyte across the space onto the workpiece. The electrolyte pressure and discharge nozzle orifice length are matched so as to provide an unconfined jet of electrolyte which has a constant diameter so as to obviate the necessity of relative movement between nozzle and workpiece. Increased temperature results in a fine non-conductive mist at the end of the electrolytic jet thereby providing a process for drilling holes of smaller size in the workpiece than prior procedures.A novel nozzle assembly is also disclosed adapted to produce holes in a workpiece by directing free streams of electrically charged electrolyte at the workpiece. The nozzle assembly has one end wall with several closely spaced orifices formed in the end wall, providing a method of forming more closely spaced holes than would be possible using separate nozzles, each with its own orifice.
