In one aspect of the invention, an apparatus for ECM grooving of a workpiece is provided. A portion of a conical workpiece is supported on a frame, with the cone opening facing a Z-axis. A slide electrode assembly is provided, including an electrode movable along the Z-axis and having, on a face aligned across a machining gap from the workpiece, a pattern of grooves to be defined on the workpiece; As an electrolyte is pumped into or through the machining gap at a constant static pressure, the electrode reacts to the pressure by moving toward or away from the workpiece to establish a certain gap width to create the necessary groove depth and definition. The force acting on the slide electrode assembly is the primary controlling factor for establishing the machining gap as the electrode and support move in response to the constant static pressure of pumped electrolyte. |
