Explanation:

Electro-Disc

harge Grinding 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. Material removal takes place in two different forms (i) ions owing to electro-chemical reaction and (ii) solid micro-chips (in very small proportion) due to mechanical abrasion.

A dielectric is flushed here to assist spark formation and debris removal. A suitable electrolyte is used here to assist electro-chemical reaction.

The grinding wheel (electrode) is made of electrically conductive material like graphite. Usually metal bonded abrasive wheel is employed here. Bonding material must be electrically conductive.

The wheel electrode is always given negative polarity. Polarity of the wheel electrode is chosen based on the tool-workpiece material combination and electrolyte.

The grinding wheel does not touch the workpiece. A small gap (called inter-electrode gap, IEG) is always maintained between them. Physical contact between the grinding wheel and workpiece always exists in ECG.

This process is free from chip clogging. In fact, so called solid chip is not generated here. Sometimes chip clogging takes place. De-clogging can be performed just by reversing the polarity.

I hope it can help you.
