ABSTRACT:
An electrode assembly (10) for an electrochemical machining apparatus comprises a plurality of electrodes (18,20) for location adjacent a workpiece (12) to be machined, at least one of the electrodes (18,20) being movable towards the workpiece (12) during an electrochemical machining operation. The moveable electrodes (18,20) have a machining face (19,21) shaped to a desired contour and at least one side member (32,34) arranged to move with the electrodes (18,20) as the electrodes approach the workpiece (12). The side members (32,34) are fixed to and move with the electrodes (18,20) at all times during the electrochemical machining operation.
