Overcut in pulsed electrochemical grinding

AbstractThe electrochemical grinding (ECG) process offers a number of advantages over conventional grinding, such as low induced stresses, large depths of cut, increased wheel life and the ability to machine delicate workpieces. However, one disadvantage is the difficulty of controlling the dimensional accuracy of the workpiece. In the present work the use of pulsed voltage in ECG is

EDM Wire Cutting

Electrochemical grinding (ECG) uses electrical current and an abrasive wheel to cut without heat stress, burrs or mechanical distortions. Oxidation stops the cutting. Then an abrasive grinding wheel removes the metal oxide, restarting cutting. Cathode-anode current flow, conductivity and electrochemical reactivity determine the ECG machining rate.

However, in ECM-based combined processes (such as electrochemical grinding (ECG), electrochemical discharge machining), both ECM and the other processes participate in material removal. The resulting synergetic effect is a 1+1=3 effect which implies that the combined effect of ECM with other process energy is more than double the benefits of individual process energies.
