摘要： The workpiece is partially immersed in a first electroerosion-machining liquid so that the surface of the liquid is positioned at a predetermined height from the lower surface of the workpiece. A wire electrode is passed vertically through the workpiece to define a machining gap therebetween which extends across the entire thickness of the workpiece including an upper portion and a lower portion divided from each other by the liquid surface of the first electroerosion-machining liquid. A second electroerosion-machining liquid having a specific resistivity greater than that of the first is supplied from above the workpiece into the machining gap along the upper portion and then allowed to diffuse into the machining gap along the lower portion. Electroerosive material removal from the workpiece occurs along the upper portion uniformly at a first rate and along the lower portion at a varying second rate which is not less than the first rate and which increases as the distance from the liquid level is increased. By relatively displacing the wire electrode and the workpiece in the horizontal plane, a contour having a non-tapered and tapered sections stepped in the direction of thickness of the workpiece is thus generated in the workpiece.

摘要： A method of and an apparatus for the electrical machining of a conductive workpiece with an axially traveling wire-form electrode displaced transversely to the workpiece along a predetermined cutting path. A high-frequency mechanical vibration is imparted to the wire-form electrode and its amplitude is controlled as a function of the shape of the wire-cutting path.

摘要： A traveling-wire electro-erosion machine which has a head assembly comprising a tubular support formed with a plurality of roller guides positioned to define a path for a traveling wire forming an electrode for electroerosion. Above the tubular support, there is provided a boxlike housing with a supply wheel and a takeup wheel for the wire and a bevel gear on the tubular support cooperates with a pinion on a motor which enables rotation of the entire assembly. A worm-gear arrangement may be used instead of the bevel gears and a different construction of the guide rollers may be provided as well, e.g. on the downwardly extending projection from the tubular body.

摘要： A wire state of use indication apparatus for use with a traveling-wire electroerosion cutting machine is disclosed in which a sensing unit instantaneously responds to the rotation of a roller disposed in the wire travel path and rotated with the electrode wire travelling in bearing contact with the roller. The number of the rotations is counted to produce a sensing signal which represents the cumulative number of rotations of the roller a number which in turn represents the amount of the electrode wire which has been drawn out of the wire storage rool by a given time instant during a given cutting operation. A processing circuit is provided to process the sensing signal with an input setting signal representing the amount of the electrode wire stored in the reel prior to the commencement of the cutting operation to produce an output signal which represents the amount of the electrode wire remaining in the reel at that time instant. The sensing unit may also provide a further sensing signal representing the instantaneous rate of rotation of the roller which rate in turn represents the instantaneous rate of drawing the wire out of the reel.

摘要： An improved wire-electrode support and guidance assembly for electrical machining comprise a first wheel rotatable about a first axis and formed along its periphery with a continuous annular recess of a uniform depth and adapted to receive and retain therein a continuous wire electrode which is axially advanced and transported from a supply reel to a collection reel through the region of a workpiece. The assembly includes a second wheel rotatable about a second axis parallel to the aforesaid first axis and having a flange of a profile substantially complementary to that of the aforesaid recess, and includes means for urging the first and second axes relatively towards each other to drive the flange of the second wheel into a mating engagement with the recess of the first wheel so that the wire electrode when passed through the recess is squeezed surfaces of the recess and the flange.

摘要： An improved method of cutting a workpiece to form a desired contour therein with a continuous wire electrode axially advanced to linearly traverse the workpiece across a cutting zone and also displaced relative to the workpiece transversely to the axis of the wire electrode. The method comprises the steps of (a) electroerosively rough-cutting the workpiece while effecting the transverse relative displacement along a first predetermined path corresponding to the desired contour and defined to generate a rough-cut contour with an overcut alpha in the workpiece, and (b) electroerosively finish-cutting the workpiece while effecting the transverse relative displacement along a second predetermined path shifted by a distance n alpha uniformly from the first predetermined path where n is a value proportional to the thickness of the workpiece traversed by the wire electrode, thereby generating a finish-cut contour coinciding with the desired contour in the workpiece.
