The article deals with a theoretical analysis of electrochemical machining using a tool electrode with curvilinear profile, vibrating into two directions. Physical phenomena occurring within the interelectrode gap have been described by a partial differential equations resulting from the balance of mass, momentum and energy of the electrolyte flowing through the gap. Equations formulated in the paper which describe the work-piece surface shape evolution and the electrolyte flow (mixture of fluid and gas) through the gap, were simplified by means of assumptions concerning the flow, distribution of the volume fracture, and the gap thickness Then, they were solved , in part analytically, and in part numerically. Calculations were performed for the assumed machining parameters, with presentation of the calculation results in the sections across and along the interelectrode gap. In the charts, the electrolyte longitudinal and transverse flow rate distributions, pressure, temperature distributions and distributions of chosen physical quantities of the electrochemical machining machining are demonstrated for the considered case of electrode vibrations synchronization.
