The article is devoted to pressing issues in the field of instrumentation and measuring equipment: the correct assignment of tolerances and landings in the manufacture and assembly of parts and assemblies of measuring transducers of physical quantities. In the process of developing converters, an obligatory design procedure is the construction of mathematical models of dimensional chains, which are analytical and numerical equations consisting of geometric dimensions shown in the drawings. Moreover, these models include both nominal geometric and angular dimensions, and the tolerances adopted on them. Using the minimum-maximum methods, it is quite simple to calculate the dimensional chains for simple parts and assemblies. Complex parts and assemblies having a large number of sizes included in the dimensional chains are calculated by statistical methods using specialized programs.
