This article deals with the search for a rational semi-finished product for parts of the integral form. Here a variant of the solution of the given problem is described based on the inverse solution of the mathematical problem. The reasons and the nature of the problem occurring in standard approaches to the calculation of the semi-finished product are shown using the example of two parts with aerodynamic curvature. The material and sheet thickness of the components are selected to suit the application. The forming process is also the same as the initial situation. The rational shape of the part can be found using the optimization solution based on the discrepancy of the contours with respect to the sweeps of the dynamic calculation and the CAD model. The new shape of the blank makes it possible to realize the forming process of the parts with minimal deviations from the contour of the 3D model.

The paper presents a variant of the formation of a part from a hard-to-form case. The calculation of the required area of the movable clamp depending on the stresses arising during the formation of the “undercut” is performed. The results of real and virtual experiments are presented. The conclusions about the applicability of the technology and the advantages that the use of a movable clamp gives are made.

The paper presents the calculation of the pressure at the first transition during the formation of the “undercuts” on which corrugation takes place. The formulas in general form for the stresses at the first transition and the required pressure depending on the length of the sweep are derived. The results with the finite element analysis of formation and field experiments are compared. The conclusions about the verification of the results are drawn.
