    Abstract: Electroerosion machining method and apparatus in which the machining gap formed between a tool electrode and a workpiece is immersed in a water liquid to surround and enclose the gap therewith in the absence of a hydrocarbon liquid surrounding the gap. The hydrocarbon liquid is injected in a forced flow under an external pressure into the machining gap immersed in, and surrounded by and enclosed with, that water liquid, whereupon electrical discharges are initiated with a discharge medium which is at least predominantly constituted with the injected hydrocarbon liquid. The water liquid may be of a relatively static mass retained in a worktank, in which mass the workpiece and at least that portion of the tool electrode which is juxtaposed therewith are immersed. The injected hydrocarbon liquid upon undergoing the electrical discharges is allowed to diffuse into the water liquid surrounding the gap to float onto the surface thereof. Alternatively, with the hydrocarbon liquid directed in at least one narrow stream selectively into the machining gap, the water liquid may be present to surround and enclose the machining gap by being directed in a flow toward the workpiece to serve as an envelope flow for the narrow stream of the hydrocarbon liquid which acts to force the water flow substantially not to enter the machining gap and then to force it to spread over a portion of the workpiece surrounding the machining gap. The tool electrode may be a continuous wire electrode.

    Abstract: A CNC process for displacing a movable member along a path on an intricate surface in a three-dimensional coordinate system is disclosed in which the surface is divided into a plurality of elementary characteristic regions each individually definable as one of different geometrical categories such as toroidal, spherical, cylindrical and planar surfaces. The process comprises establishing a general equation for each of these categories and storing the established general equations into a memory unit for a computer. Data required to adapt each of the stored general equations to a corresponding one of the characteristic regions in the three-dimensional coordinate system are inputted into the computer to reduce the general equations to their respective specific equations in which no more than three coordinates are variable. A sequence of incremental two-dimensional positions defined in the system by first and second coordinates thereof are inputted into the computer to allow it to compute, for each position on the path, the value of the third coordinate from the first and second coordinates and the specific equations, thereby determining the path along which the member is moved.

    Abstract: In a process and apparatus for electrodeposition, particularly suitable for the electroplating of a substrate (1) having a large surface area and a complicated profile, an electrode (2) having a small electrode surface area (2a) is used, which is to face a part of the substrate (1) with an electrodeposition gap (G) washed with electrolyte fluid. Small high-frequency mechanical vibrations act on the electrode (2), while a preferably pulsed electrodeposition current flows between the electrode (2) and the workpiece (1), which are displaced relative to one another so that the electrode surface (2a) three-dimensionally sweeps a selected substrate zone, whereby an electrodeposited layer of the desired uniform thickness is formed at an increased rate. The electrode (2) is preferably formed in an electrode arrangement (3) which comprises an electromechanical transducer (4), a flare (6) and the electrode (2) in that order. Driving units (12, 13, 14) react to a numerical control instrument (15) for the purpose of a three-dimensional relative displacement between the electrode arrangement (3) and the substrate (1). An automatic electrode-changing unit (17, 18, 19) is connected to the control instrument (15), so that different electrodes (102, 202, 302) can be introduced one after the other into electrodeposition positions for successive substrate zones.

    Abstract: A positioning device for a tool electrode on an electrical machine tool, comprising: a tool head and a swivel electrode support for securely holding the tool electrode and adapted to be swivelably carried by the tool head whereby to allow the axis of the tool electrode to be swung relative to the tool head about a fulcrum lying on the axis of the latter. An electrode centering assembly is used to align the axis of the tool electrode with the axis of the tool head and comprises a plurality of axial drive units operative for displacement and pressurization along the respective radially equi-spaced axes, each unit comprising a pressure plate having a pressure surface extending in parallel with the axis of the tool head and slidably received in a casing and resiliently supported thereby to maintain the parallelism. Motors are used to conjointly advance the casings to displace the pressure plates towards and urge them against the tool electrode. The parallel surfaces of the pressure plates urged against the tool electrode thus rotate the latter about the fulcrum to bring it parallel with the pressure surfaces and hence into a precise axial alignment with the tool head. Support retainer means is coupled to the tool head and actuatable, after establishment of the axial alignment or parallelism, to fixedly secure the swivel electrode support to the tool head.
