The paper is concerned with development of calculation procedure of residual forming of type parts "bush" by electric resistance surfacing with a wire (ERSWW) using the finite element method (FEM) based on the theory of non-isothermal plastic flow. The adequacy of the design model is confirmed by the experimental data. The developed calculation procedure of residual forming allows to predict the possible axial and radial movement of type parts "bush" by ERSWW of outer surfaces in a single layer, that allows to make a decision on the feasibility and appropriateness of technology ERSWW during restoring of type parts "bush".
