The results of the work aimed at reducing organizational downtime of equipment associated with the readjustment of machines during the transition to the manufacture of another type of product are presented. A set of measures is proposed, which includes the formalization of the technological process in a matrix way, which allows describing the processing from the point of view of the cutting tool and machine tools used. After formalization, various methods of cluster analysis were applied to determine the sequence of starting parts into processing, at which the equipment readjustment time would be minimal. For the study, equipment having a block layout was selected. A key place in the article is given to the problem of determining the procedure for replacing equipment in machine blocks with a built-up sequence of starting parts for processing. Several algorithms are proposed, among which the best one in terms of the number of necessary replacements in the equipment blocks has been selected.
