The growing complexity of mechanical engineering products is changing the strategy of its production. Optimization of thousands of parameters to create competitive products today is almost impossible without the use of digital twin (CD) technology, although the CD technology itself, particularly in the foundry and metallurgical industry, is still at an early stage of development. If to ensure the reliability and safety of machines and mechanisms and their metal structures requires a significant increase in the number of tests, they are faster and cheaper to do in cyberspace at the design stage than at a later stage in metal. The review considers some examples of application of CD technology for the design of cast metal billets, optimization of their designs in the manufacture of the additive method. A review of the definitions: what is diabetes, what technologies reveal this concept, how the use of diabetes affects the development of additive production of metal products.
For the construction of metal products, such concepts as “bionic design” and “generative design” are noted, which change the nature of human interaction with the program, which becomes an effectivetool of the creative process. Examples of computer engineering at topological optimization of designs of metal preparations are shown. A review of a number of sources of information shows that among the advanced technologies CD is an integrator of almost all “end-to-end” digital technologies, acts as a driver, provides the prerequisites for development and allows companies and entire industries to move to sustainable development. CD technology has great prospects because it is necessary not only for the creation and operation of a modern “smart” product, but also for its
regular maintenance, updating and constant adaptation to new requirements and conditions with the transfer of accumulated data and methods to create new machines, structures and materials.
