title = "Micro electro discharge machining by uniform tool shape Method - Study of relative wear",
abstract = "Tool wear in micro electro discharge machining (micro EDM) is much higher than the conventional EDM. This paper classifies the types of Micro EDM tool wear and reviews the existing tool wear compensation techniques. Limitations of existing methods are discussed and an alternate approach of micromachining using uniform tool shape is proposed. The steps involved in the new approach are outlined. Study of relative wear is identified as the first part in understanding and implementing the proposed approach. Experimental investigation of the various factors affecting the relative wear was carried out and the preliminary results are presented. It is realized that the relative wear decreases with increase in discharge energy. For a given discharge energy it is observed that relative wear decreases with an increase in capacitance of the discharge circuit and increase in electrode size and during the machining of material with lower thermal conductivity. Creation of tool wear compensated part geometry, automated tool path generation and CAD/CAM integration have been planned in the second part of this study.",
