    Abstract: An EMD method and apparatus, especially for a cavity-sinking type of machining, wherein a combination of magnetic fluxes and ultrasonic waves is applied externally to the region of a machining recess being progressively formed in a workpiece electrode juxtaposed with a tool electrode while the electrodes are displaced relative to one another and a succession of machining electrical pulses are applied across a dielectric flooded machining gap provided therebetween.

    Abstract: A multiplicity of conductive pipe elements are arranged in parallel with one another in mutually insulating relationship and are secured together in a cup to form a multiple electrode assembly. The assembly is advanced into a workpiece in the machining feed direction and additionally is displaced relative to the workpiece by a Z-axis motor in a plane orthogonal to the machining feed direction by X-axis and Y-axis motors a distance slightly in excess of the uniform spacing (Gx,Gy) between the pipe electrodes along each of two mutually orthogonal axes in the plane. The additional displacement may be effected alternatively by vibrating the pipe elements transversely to the axes thereof with an amplitude essentially equal to the said distance. For further machining of the same workpiece, a proportion of the pipe elements may be released from the securely held state and individually advanced and/or retracted with rates of movement determining the shapes of the final machined contour. The power supply comprises an AC-DC-HF-DC Pulse inverter having multiple output terminals respectively connected to the multiple pipe elements. Machining liquid is pumped to and from the machining gaps via the pipe elements.

    Abstract: A grinding wheel capable of detecting and a method of monitoring it to detect, the development of a crack or like damage therein are disclosed. The wheel is constituted of an electrically nonconductive body having an electrically conductive strip, e.g. a thin film of an electrically conductive ink printed, of an electrically conductive paint applied, of a metal electrolessly or chemically deposited or of a metal electrolytically deposited, in a pattern, say, of quasi-circular or spiral configuration, on a portion of at least one side surface of the body. A current source is connected to the opposite ends of the conductive strip to pass an electric circuit therethrough. When a crack or like damage develops in the wheel body being rotated to perform a grinding operation, the circuit will be broken or a change in the current will occur, signaling the damage or crack formation.

    Abstract: A method of and an apparatus for electroerosively machining a 3D cavity in a workpiece using a slender tool electrode, e.g. in the form of a wire or thin rod, which is generally independent of desired cavity in shape and axially juxtaposed with the workpiece to define a liquid-flooded machining gap therebetween. The slender tool electrode and the workpiece are relatively displaced three-dimensionally along mutually orthogonal three independent axes so that the slender tool electrode moves in a scanning manner over the workpiece surface while an ultrasonic vibration is imparted to the scanning slender tool electrode. A machining wear of the electrode is sensed in response preferably to the vibration signal and the wear-compensation feed is effected to axially advance the slender electrode independently of the three-dimensional cavity-forming movement to the tool electrode and the workpiece.
