ABSTRACT:The purpose of this study is to provide an outline of the electrochemical machining process as well as its concepts. It also focuses on a literature review to discuss key process parameters based on previous studies. Electrochemical machining has grown in importance as a significant electro-machining process with unique features. These machining processes provide a better or, in some cases, the only option for producing accurate 3-D complex shaped macro, micro, and Nano features and components from difficult–to–machine materials. Technological advancements in the electrochemical micromachining technique have been described.

KEYWORDS: ECM, electrochemical micromachining, PECM,MRR.
