Estimation of the process localization at the electrochemical machining by microsecond pulses of bipolar current

Here we present a model of anode dissolution at the electrochemical machining by bipolar microsecond pulses at current densities up to 100 A/cm2, taking into account the non-stationary nature of anode and cathode potentials installation during the pulse effect and a preliminary reverse polarity pulse influence on anode potential, as well as change of temperature and gas-filling of an electrolyte in interelectrode space (IES). The task of optimization of the process parameters, including the coordination of a preliminary reverse polarity pulse parameter and working pulse for reaching maximum output at a given factor of localization, is formulated and solved.
