ABSTRACT:
The invention is an electrolytic microfinishing process which utilizes a conductive tool as a cathode and a conductive workpiece as an anode both connected to a power supply. Electrolytic fluid is pumped between the tool and workpiece, creating a decomposition of the workpiece surface allowing the surface of the workpiece to be removed or wiped away by the interaction of the flowing electrolyte and rotation of the tool without generating any heat at a rate significantly faster than any other known machining process. The tool has no contact with the workpiece and accordingly, requires very low clamping loads to hold the workpiece in the spindle during the finishing operation. Due to the low clamping loads, the distortion of the workpiece is completely eliminated. Modulating the power supply during the work cycle allows the use of a single tool for both roughing and finishing as a continuous cycle to significantly provide surface finishes previously unobtainable.
