The interrelated tasks of determining the parameters of mechanical components of structures are consid-ered, taking into account the probabilistic nature of mating parts dimensions. The aim of the work is to develop design procedures that ensure determination of tolerances in parts connection (direct task) and the selection of standard fits that meet the requirements for the accuracy of mating elements connection (inverse task). When developing design procedures, standard calculation methods and original approaches based on statistical modeling of mating parts dimensions to determine their maximum dimensions and connection parameters were used. On the basis of the proposed design procedures, an electronic reference book on the System of Fits and Tolerances has been developed. Its application provides the user with reference data according to the standards of the System of Fits and Tolerances, and also allows automating the solution of direct and inverse problem of determining mating parts parameters for smooth cylindrical joints, including limit calibres and rolling bearings, during electromechanical devices design
Key words: : CAD/CAM systems, statistical modeling, tolerances and fits, standard fits, clearances and interferences, fit tolerance, standard tolerance grade, fits of rolling bearings and limit calibres.
