MODERN PRODUCTION TECHNOLOGIES APPLIED TO VARIOUS LIFE CYCLE PHASES OF PRODUCTS AND MACHINE PARTS

Abstract

The study objective is to identify modern production technologies used at almost all phases of the life cycle. To achieve this objective, there have been analyzed and reviewed papers and foreign studies published mainly within 2016-2020 in journals covered by SCOPUS and WoS indexing services, as well as studies of Russian scientists over the past ten years, which are indexed in the above-mentioned international services, as well as in the national RSCI system. The references analyzed in this paper prove that additive technologies are inferior to combined (additive-subtractive, additive-subtractive-hardened, etc.) technologies from the point of view of obtaining high-quality products at the present stage of production development. Conclusions: it is proposed to include the stage of capital repairs and updating of the general model at the stage of modeling the life cycle of machine-building products, which can be the right direction for choosing the most effective technology regardless of the life cycle phase; the choice of technology for the production stage of a particular product or part should be justified in terms of improving the basic operational properties and increase of the residual resource.
