Abstract: An attempt has been made to find out the effects of the electrode condition on the micro drilled deep holes with electrical discharge machining process. With optimised machining parameters for copper electrode-brass work material combination, experiments were carried out with different electrode conditions viz. straight, tilted and bent electrodes. The objective was to find out the signatures of these electrode conditions on the size and shape of the hole obtained from the experimental results. Based on the results a geometrical model is constructed and presented.
