Using the analysis of dimensions, the generalized method of designing rational modes of multiple drawing of wire with dry soapy technological lubricant is improved theoretically and experimentally, taking into account the friction mode in the drawers, other process parameters and determining the acceptable multiplicity of metal flow deformation in the mill. An algorithm is developed for calculating the rational number of rods passes through the dies during flow drawing, the use of which allows, in its implementation in practice, to ensure the stability of the technological process with the absence of wire breaks with the minimum necessary (optimal) number of metal deformation cycles and the corresponding energy consumption. The obtained results are consistent with the practice of industrial drawing with the use of dry technological lubricants on a soap base and can be used in the development of new ones and in checking the rationality of existing technological drawing processes. In the future, it is advisable to develop a program for automatic calculation according to the above algorithm for the rational number of passes during dry drawing, as well as use the presented approach to expand the initial statistical database, taking into account the properties of other steel grades that are deformed in the processes of dry and wet drawing.

Key words: metrology, dimensional analysis, measurements, wire drawing, process stability.
