To study the influence of polarization on the form of the workpiece, a method of transformation of the interelectrode space to a rectangle (for a two-dimensional system) was proposed. The potentials in this region were calculated by the superrelaxation method. The results of the calculation show a pronounced effect of polarization on the final form of the workpiece in comparison with an analogous calculation involving no electrode polarization. The Joule heat evolved in the streaming electrolyte and gas bubbles formed during electrolysis have also a pronounced influence on the course of the machining process.
