摘要： A support mechanism for a workpiece cut off by electrical discharges in a travelling wire EDM apparatus. The workpiece is supported between support members provided with clamps. One support member is controllably pivotable around a horizontal axis, while the second support member is displaceable vertically and horizontally along crossed axes. In addition, the second support member may be rotated around a vertical axis. Through appropriate sequential operation of the clamps and relative displacement of the support members, the areas of the workpiece clamped by the clamps may be changed at will, and the cuttings from the workpiece may be supported by one of the clamp members to prevent the fall of the cuttings at the end of a cutting operation.

摘要： A method and apparatus for threading or rethreading the end of an electrode wire through an aperture in a workpiece in which a cut is to be effected, by electrical discharges in a machining zone between the electrode wire and the workpiece. While the end of the electrode wire is brought in proximity with the inlet of the aperture in the workpiece, the end of the electrode wire is disposed in a pressurized fluid flowing towards the inlet of the aperture in the workpiece such that the end of the electrode wire is automatically centered relative to the aperture, and threading the end of the wire through the aperture.

摘要： A unitary assembly supporting an electrode wire guide member and a machining fluid nozzle providing a jet of fluid coaxially disposed with the wire, in a travelling wire EDM apparatus. The unitary assembly is mounted on a plate connected through a universal swivel joint to the lower slide of a cross-slide table. Lateral displacements of the plate cause the unitary assembly to orient itself under the action of a pair of fingers mounted on the plate co-operating each with a ramp mounted on the cross-slide table such as the unitary assembly constantly remains coaxial with the electrode wire.

摘要： In the electrical discharge machining of the surface of a recess in a workpiece electrode to a shape corresponding to that of a tool electrode, the electrodes are relatively displaced, during a finishing phase of machining, along an axis of penetration and simultaneously in a plane perpendicular to the axis of penetration with a cyclic translational movement whose amplitude increases with the penetration of the tool in the workpiece. This provides a virtual three-dimensional dilatation of the tool as it advances, and enables control of the sparking in both the frontal and lateral parts of the machining zone. The cyclic translational movements are obtained from a rotatable shaft having an axis parallel to the axis of penetration and an eccentric member cooperating with the rotatable shaft to slide relative to the shaft in a direction forming a predetermined angle with the direction of penetration, the eccentric member being rotated in unison with the shaft about its axis.

摘要： An EDM method and apparatus for cutting a workpiece by a wire electrode in the form of a metallic tape or wire, in which the traction exerted on the wire electrode by the mechanism feeding the wire electrode in the machining zone between the wire electrode and the workpiece is modified momentarily, and the variation of machining rate caused by the momentary modification of the force of traction exerted on the wire electrode is detected. The direction in which the machining rate is changed provides an indication of the effect, on the wire electrode, of the transverse forces which deflect the wire in the machining zone, relative to its longitudinal axis. The direction in which the machining rate varies is used to select the direction in which a predetermined machining parameter affecting the transverse forces applied on the wire electrode is changed, such as to maintain the wire electrode properly aligned along its longitudinal axis.

摘要： The present invention is an EDM (Electrical discharge machining) process and apparatus for machining an electrode workpiece by means of an electrode tool wherein the electrodes are displaced relative to each other along a principal feed axis while, simultaneously, the electrodes are displaced relative to each other along an orbital path in a plane perpendicular to the principal feed axis, such as to produce between the electrodes a three-dimensional translation motion, and for providing between the electrodes an average machining gap wider than the gap width sustaining electrical discharges. The invention provides a control of the amplitude of the relative translation motion of the electrodes while displacing the direction of said motion as soon as a predetermined orbiting path limit is reached such as to allow a rapid increase of the gap between the electrodes when the electrode tool is retracted.

摘要： A hydraulic machine combining a pump and a turbine has pump and turbine runners keyed on a common shaft and designed for the same direction of rotation. The pump is connected to a head by at least two partial volutes, and the turbine by at least two partial volutes wound in opposite direction to those of the pump. Sleeve valves between the runners and their partial volutes enable draining of the pump during turbine operation, and vice versa.
