Abstract
SACE (Spark Assisted Chemical Engraving) or ECDM (Electro Chemical Discharge Machining) is an interesting micro m/c technique, reported by Kurafuji and Suda, in 1968. It is a non- conventional machining method preferred in micromachining non conducting or semi conducting materials; particularly, hard to machine materials like glass, ceramics, composites etc. The Tool used in ECDM one of the important factor in improving machining characteristic. Through this paper an extensive review has been made and reported on tool modification, enhancements and up-gradation and it has been found that profiles and rotary tools are much popular for micro machining and higher accuracy point of view.
