Abstract
A method and apparatus for electromechanical grinding is provided. An pulsed alternating waveform is applied between an anodic workpiece and cathodic grinding wheel to physically remove and electrochemically remove material from the anodic workpiece.
Claims11
A method for electromechanical grinding comprising:
- rotating an electrically conductive grinding wheel;
- applying a first voltage between the electrically conductive grinding wheel and an electrically conductive workpiece;
- applying a first force vector towards the electrically conductive workpiece via the electrically conductive grinding wheel to remove material from the electrically conductive workpiece;
- and
- after removing a desired percentage of material from the electrically conductive workpiece:
- a) applying a second force vector towards the electrically conductive workpiece, the second force vector being less than the first force vector, and b) applying a second voltage between the electrically conductive grinding wheel and the electrically conductive workpiece to further remove material from the electrically conductive workpiece.
