Abstract

Under condition of electrochemical sinking the intricate processes of heat energy, electric charge and electrode reaction products transport occur in the machining area. Heat and electrode reaction products are removed by flowing electrolyte. As a result of inertia of this process the uneven distributions of electrolyte physlcal properties. current efficiency. voltage drops in the workpiece. interelectrode gap tnickness and its standard deviation are not uniform. The tests showed that in the case of electrochemical sinking standard deviation of iriterelectrode gap thickness decreases with machined surface decrease. This can be applied in practice by using nonprofiled electrode with surface many times smaller than machined surface and different kinematics than that in sinking.
