Abstract: Process of electrochemical machining is modeled by means of the solution of a Schwartz problem for complex potential on parametrical region in the form of a strip. Unlike a flat problem for determination of electric field strength integral transformations of analytical function are used. On this basis the numerical -analytical method of the solution of a problem which allowed to use for modeling experimental data, namely, nonmonotonic dependence of a special type of current density on anode potential is developed. It allows explaining emergence in natural experiment on the processed surface of three zones: the zone of active dissolution, a zone of lack of dissolution corresponding to the falling part of dependence, and a zone of weak dissolution which corresponds to small current density.
