ABSTRACT:
A machine for electrochemically machining (ECM) a workpiece having a stacking axis and first and second opposite sides includes a pair of cathode tools. The first and second tools have first and second longitudinal axes, respectively, disposed substantially perpendicularly to the workpiece stacking axis. The first and second tools also include the first and second transverse axes, respectively, disposed perpendicularly to the first and second longitudinal axes, respectively, and substantially parallel to the workpiece stacking axis. The machine is effective for practicing an improved method of moving the first and second tools along the first and second longitudinal axes and along the first and second transverse axes, respectively, toward the workpiece for the electrochemical machining thereof. By moving the respective cathode tools along both longitudinal and transverse axes, a selectively variable resultant feedrate direction is obtained which is inclined relative to the workpiece stacking axis.
