Background. The application of the centerless grinding method, despite its high efficiency, is fraught with certain difficulties due to the lack of a clearly formulated and normatively fixed methodology for designing and implementing operational technologies. Materials and methods. Research conducted on the basis of theoretical and practical justifications, developed models of technological preparation of through-hole centerless grinding operations, scientifically confirm the need for a thorough analysis of the conditions and limitations inherent in this processing method when determining the values of allowances. Design procedures related to the determination of the tolerance value require the expansion of traditional information support, as well as adjustments and additions to well-known techniques during technology development. The developed dependencies linking the settings with the characteristics of the working area and the actual state of the technological system allow such an analysis to be carried out in all sections of the processing area. Results. Causal relationships have been identified that determine how the amount of the allowance affects the dynamics of processing in different parts of the work area. Based on these connections, methodological, algorithmic and software tools were created to determine the allowance as part of the technological preparation of through-centerless grinding operations. Conclusions. Causal relationships have been identified that determine how the amount of the allowance affects the dynamics of processing in different parts of the work area. Based on these connections, methodological, algorithmic and software tools were created to determine the allowance as part of the technological preparation of throughcenterless grinding operations.
