Abstract

The new developments in engineering materials such as titanium alloys, high performance steels, precious metals, ceramics, composites, polymers, high strength alloys, thin film nano-structured flexible electronics, photopolymers etc requires advanced machining process for its shaping and to be functional. Electrochemical discharge machining process is a high capability machining process and suitable for different conducting and nonconducting materials irrespective to their strength. This machining process has a combined effect of electrochemical machining process and electro discharge machining process both. A number of variants have been developed for making symmetrical and unsymmetrical holes, straight and curved channels, slitting, cutting etc by using phenomena of electrochemical machining process. Present paper deals with the different configurations of electrochemical discharge micro machining process.
