ABSTRACT:
A multi-axis machine, with numerical control on each axis, is used to drive the tool and workpiece movements necessary to machining complex airfoil geometry. Tooling is typically made of a metal such as brass or other low cost material and rotates during machining. The tooling may be any shape(cylindrical, conical) and size depending on application. A DC power (continuous or pulsed) is used to provide voltage across the tool and workpiece. A medium such as water, de-ionized water, or electrolyte (such as sodium nitrite) is provided between the tool and workpiece. Workpiece metal is removed in a controlled manner by high intensity thermal erosion.
