In the article the parameters of shaping operations of internal axisymmetric cylindrical flanging are considered. The article is written to improve the quality and speed of flanging round holes development from sheet blanks and tooling construction by increasing the accuracy of hole diameter calculation for flanging in the automated mode of building three-dimensional models of workpiece and a flanged product. Given formulas increase the accuracy of hole diameter calculation for flanging, taking into account the deformed condition of the sheet blank. The accuracy of the hole diameter calculation for flanging according to the given formulas is determined by comparing the mass of the workpiece with the mass of the flanged part. CAD system algorithm for automated construction of the flanged parts sketch and determination of technological parameters is implemented. The parameterized scheme of a typical construction of a flanging stamp is presented. The constructed schemes allow making changes in their parameters and providing automatic representation of calculation results and also their correct graphic interpretation. Discussion of the article results allows drawing conclusions about correctness of the given mathematical model and its applicability for the automated construction of three-dimensional models of the flanged details that will allow simplifying technological development and constructed documentation with simultaneous increase of their accuracy and reducing costs of production preparation.
