Abstract. The complexity of integrating computer-aided design systems, in particular AutoCAD, and computer-aided design of technological processes is caused by the lack of the necessary interoperability between them. A method of parallel formation of the geometric and parametric model of a part is proposed, which makes it possible to ensure the necessary compatibility of models. The method is based on the creation of a library of parametric models of structural elements. Setting the element by displaying the parameters on the screen automatically leads to the setting of its geometric image with subsequent attachment to the forming image of the part. The method requires the creation of appropriate libraries of structural elements and the organization of a single information space for technological preparation of production. The proposed method reduces the time for designing parts and developing technological processes.

Keywords: computer-aided process planning system, unified information space, geometric model of part, parametric model of part, interoperability, technological preparation of production
