Representation of the Product as an Object of Digitalization of Production with a Structured Set of Modules

Abstract

Disadvantages of the traditional description of a mechanical engineering product are shown, which are based on technological features oriented to single, typical and group operations of the technological process. It is proposed to represent the design of the product and its parts with a structured set of relevant technological modules, in the form of a graph of a hierarchical structure. The availability of a unified methodological base makes it possible to control the development of constructively complex products, minimize duplication in the creation of new designs and effectively develope resource-saving technologies for their manufacture. The choice of the method for assessing the manufacturability of the product design is substantiated by the labor intensity of the processes at the stages of its life cycle and the formation of a set of criteria that generalize the assessment of design and technological solutions by coefficients that take into account their degree of influence on the technical and economic indicators of the processes. On the basis of a technical and economic analysis, a method for the integral assessment of production manufacturability in the product life cycle has been formed. The method combines various coefficients of manufacturability, taking into account the degree of their influence on the labor intensity of production and maintenance, repair and disposal of the product structure. Based on the results of the feasibility study, it was proposed to understand the manufacturability of the product design at the stages of its production and disposal as production adaptability.
