Description:

Abstract:

An apparatus and method of electrochemically machining a surface of revolution on a rotating workpiece includes rotating the workpiece about its axis and positioning an electrochemical machining tool having an essentially flat machining surface adjacent the workpiece to form a gap. The tool includes a machining surface having a straight edge in a plane which also includes the axis of the workpiece. The machining surface is oriented essentially perpendicular to the plane so that the smallest gap dimension exists between the straight edge of the tool and the workpiece. Electrolyte is introduced into the gap in a direction so that it flows across the machining surface and between the tool and the workpiece in a direction parallel to the direction of relative movement and toward the smallest gap dimension.
