Abstract: Assembly is the final, critically important stage in the production of any machines and devices, but its importance increases many times in the manufacture of high–precision products. In industries such as the military-industrial complex, aerospace, precision machine tool and bearing manufacturing, where tolerances are measured in microns, and people's lives or the success of expensive projects depend on reliability, assembly goes beyond simply connecting parts. Here we are talking about a high-tech process that requires extreme precision, special conditions and qualified personnel. The precision characteristics of such products often exceed the capabilities of processing equipment, and existing methods for achieving precision during assembly do not have sufficient versatility and depend on the type of production. The approaches being developed to solve these problems also do not have sufficient versatility, that is, they do not consider all the elements of the described problem comprehensively. In addition, these approaches do not take into account the relationship between the process design of machining and mechanical assembly production. To solve this problem in a comprehensive manner, a set of design procedures of the system of accounting requirements for the assembly in the design of manufacturing methods of machining was developed. However, the specified system requires further development in terms of establishing the relationship between the designing preproduction and process design of multi-product production and the transition to the assessment of production manufacturability, which requires the improvement of the methodological, mathematical and algorithmic support of the enlarged block of design procedures of analyzing the requirements of the assembly of a high-precision product. This article discusses in detail the methodology of identifying critical requirements of the assembly of high-precision products based on the construction of a generalized graph of surfaces. The development of this methodology makes it possible to complete the improvement of the methodological support of the enlarged block of design procedures and proceed to further stages of its modernization.
