An electrochemical process for cutting metals and conducting refractory materials using a pulsating voltage has been developed. A laboratory type electrochemical saw is described which has been successfully applied to cut different metals and sintered V2O3. The influence of different operating variables on cutting rate and precision has been studied for the cutting of nickel in a nitrate electrolyte.
