Method of presenting a product as an object of digitalization of manufactoring by a structured set of modules

Abstract

The shortcomings of the traditional description of mechanical engineering product are shown, which are based on technological features oriented to single, typical and group operations of the technological process. It was proposed to represent the design of product and its parts with a structured set of relevant technological modules, in the form of a graph of hierarchical structure. The numerical characteristics of the structure of the graph of product, its levels, nodes, branches are considered. The description of the structures of products by a hierarchical graph at the first level makes it possible to identify the functional technological modules of products and, on their basis, to construct a unified classification and to suggest coding products, both for production objects and operation. Representation of parts by a set of modules allows identifying surface modules, working and binding, and on their basis to build a single classification of parts focused on different stages of the product life cycle. The presence of a unified methodological base allows managing the development of constructively complex products, minimizing duplication in the creation of new designs and effectively developing resource-saving technologies for their manufacture.
