Abstract The disadvantages of the traditional description of a mechanical engineering product are considered, which are based on features focused on single, typical and group operations of the technological process. It is proposed to design and manufacture individual elements of parts and the product as a whole from the standpoint of operation and monitoring of its condition using the modular approach in engineering and technology. The representation of parts by sets of modules makes it possible to identify the locating, working and binding modules of the surfaces and on their basis to build a unified classification of parts focused on various stages of the product life cycle. The fundamentals of the locating theory are updated, taking into account the revision of the existing description from theoretical mechanics by means of the position of 3 coordinate points; for the transition to a new description from the theory of machines and mechanisms by depriving of object of locating the degrees of freedom (mobility) in the technical system (design, technological, measuring one). It is shown how the design of the production technology of the product and the measurement of its characteristics is carried out in a system that includes equipment and facilities as mechanisms, the closing link of which are locating items.
Keywords design, product, object, module, set of bases, locating, reference point, contact point, locating scheme, locating error
