The highly accurate two-phase flushing flow model for the electrical discharge machining (EDM) process will be extended into a three-phase (solid liquid gaseous) model such that also the gas phase in the working gap is considered. The material loading resulting from single and multiple electrical discharges will be studied as to the influence of all phases on the thermal loading of the workpiece and the mechanical loading due to the cavitation of the gas bubbles. In situ particle-image velocimetry (PIV) measurements of the flushing flow will be performed to validate the results and in cooperation with the sub-project F02/EDM, the three-phase flushing flow model will be incorporated into the Process Signature of the EDM process.
