ABSTRACT:
An apparatus for displacing at least one of the electrodes of an electrical discharge machine laterally in a plane perpendicular to the axis of relative longitudinal feed of the electrodes, with an amplitude proportional to the longitudinal displacement of the electrodes. The apparatus comprises a rotatable shaft longitudinally controlled as a function of the axial position of one of the electrodes. An eccentric member is driven in rotation by the shaft, and the amount of eccentricity of rotation of the eccentric member is controlled by a moveable camming member supported at three points, one of the points being a fixed pivot point on the axis of the shaft and the two other points having an axial position and a radial position varying as a function of the longitudinal displacement of the shaft and defining the amount of eccentricity of the eccentric member.
