Electro-Chemical Grinding. EDG is not a hybrid process. ECG is one hybrid process. It is one thermal energy based non-conventional machining process. ECG is based on electro-chemical energy as well as mechanical energy. Here material removal takes place by melting and vaporization due to intense localized heat generated by electric spark.

The thinning efficiency of chemical polishing is 25 μm per minute. XRD patterns indicate that the chemical polishing actually eliminates the macro- and micro-stress induced by mechanical grinding. TEM observation demonstrates that chemical polishing reduces the amount of hydride artefacts, especially hydrides with large size.
