The electrochemical grinding process (ECG) is a subset of the machining family known as electrochemical machining (ECM). According to [1], it can be categorised as a hybrid ECM process because of the presence of mechanical abrasion (MA) next to the electrochemical dissolution (ECD) as seen in Fig. 1-2. It utilises a negatively charged
