Abstract

A six axis ECM machine is provided for electrochemically machining the airfoil blades of an integrally bladed rotor of a gas turbine engine. The cathodes of the machine each move along two different sets of axes, a right X-axis and Y-axis and left X-axis and Y-axis, relative to a workpart machining position in the electrolyte chamber while the rotor is moved vertically along a Z-axis. The rotor is indexable about a sixth horizontal axis to present individual airfoil blades for machining at the workpart machining position. The rotor is fixtured on the Z-axis slide with its lateral center plane at an angle relative to the cathodes at the workpart machining position and the cathodes have recessed pockets to receive airfoil blades immediately adjacent the individual blade being machined as the individual blade is positioned at the workpart machining position. These features of the machine provide full access of the cathodes to the blade to ECM the sides, leading and trailing edges, fillet radii and platform of the blade.
