The article considers the majority of modern foreign and domestic CAD TP, which solve many problems of technological preparation of production. However, in most systems, the used method of automated design of technological processes remains incomprehensible, the existing organizational structure of pre-production is not taken into account, the correction of actual data (cutting conditions, time standards) does not meet the requirements of modern aviation production. The article proposes to actively use the integrated design method in CAD TP systems.
This paper discusses the process of creating a digital twin of a product, which is a virtual model of a mechanical connection. The modeling was carried out using the Pro/ENGINEER software, which allows building a three-dimensional model of the product assembly process, which is a set of three-dimensional electronic models of the product, equipment and tools. The models include a mathematical description of the geometric, physical-mechanical and technical parameters of the objects under consideration. It is shown that it is the formation of a triad of electronic models: product-man-equipment in the considered area of computer-aided design of technological processes for the implementation of mechanical connections that allows modeling with the necessary accuracy and adequacy.
The paper deals with the issues of automation of technological design, for which it is proposed to introduce the concept of a structured reference space of a technological process, which is understood as a special design created on a set of processes used in the manufacture of products, on which their ratio is set for individual subsets of the materialization processes of a product. To describe the reference space of the technological process, a method for solving methodological and mathematical problems is proposed - according to the information image of objects and processes; analysis and synthesis of processes; synthesis of equipment layout diagrams; machine methods of systematization. The latter made it possible to develop a qualitatively new approach to organizing data on technological processes, based on an object model for representing and processing information.
The article considers the use of quality management methods for the safety of industrial, transport and municipal facilities in the face of modern challenges: international strategic instability, hybrid war and the coronavirus pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
