The work is devoted to the development and practical application of a surrogate model of electrochemical machining of the outer workpiece cylindrical surface using a tool-electrode with a partially insulated surface. The model earlier developed by the authors and the method of its numerical solution were used as the original mathematical model. The approximations of the results of numerical simulation of the primary distribution of current density were used. In contrast to the original mathematical model, which requires time-consuming calculations for each set of process parameters (the minimum interelectrode gap, the workpiece radius, the angle of active area of partially insulated tool electrode), the developed surrogate model enables performing all necessary calculations using the analytical dependences. The surrogate model enables more precise determining the rational modes of electrochemical machining, which provide the required compromise between the accuracy and productivity of the process, using significantly lower computational resources.
