Abstract: The problem of improving machine-building production is of paramount importance. The required precision is achieved with the traditional methods of manufacturing. They are: the complication of the processing equipment and the applying of the information technologies and measurement technologies. At present, the functional precision of the high-precision products (the devices and the machines) has surpassed the precision of the machining equipment and the assembly equipment almost by a decade. This leads to the problem of the achieving of the specified quality and accuracy of the high-precision products during their manufacture. Now there are just the segmental solutions for some specific tasks of these issues, such as the upgrading of the quality and the precision of the production, the reduction of the material costs, the adoption of the resource-saving technologies and so on. But the unifying vision of the system meeting the real requirements does not exist. In the present paper the discipline of the holistic approach (complex of design procedures) which provide the effectiveness of the realization of the assembly operations is considered. The effective realization of the assembly operations is based on the links between the process design of the manufacturing of the highprecision products and the process design of the assembly production of the high-precision products. Moreover, mathematical models and approaches of realization of the complex are considered in this paper.
Index terms: assembly production; complex of design procedures; high-precision units; graph of the sizes; graph of the mating of elements of assembly; system of automated sequencing of manufacturing methods.
