Abstract

The paper considers software for the process of manufacturing thin-walled cylindrical precision shells with axial section of figured contour by the method of rotary drawing by a direct method with wall thinning. The authors propose a variant of operational parametric modeling in the Kompas-3D environment with the purpose of calculating geometric parameters and obtaining a complete set of drawings of finished products and semi-finished products, a struc-turally completed and initial tube billet for the manufacture of said shells. The authors carried out a complete statement of the problem and justified the production necessity to solve this problem. Some questions of operational parametric simulation in the Kompass-3D environment in production conditions are considered. The composition of the input and output information is determined. The solution of the inverse problem is represented in the form of a sequence of steps from the finished product to the initial form of the billet.
