The work is devoted to the justification of the choice of a rational range of voltage pulses duration on the basis of comparing the time of the anodic dissolution start with the time of the double electric layer charge during electrochemical dimensional micromachining. The range of short-circuit times as the limit of the maximum voltage pulse duration is justified. The simulation of dimensional electrochemical micromachining using ultrashort voltage pulses without taking into account changes in the properties of the interelectrode environment is performed. The zones of the current density, which have different influence on the process of dimensional electrochemical micromachining, are revealed. An approach to the selection of an effective voltage pulse duration based on the analysis of the character of the time zones of the process is proposed.
