| Summary: | Background. The use of centerless grinding methods in modern production systems,
despite their high productivity, is hindered for reasons related to insufficient scientific
study of the issues of their technological preparation. First of all, this applies to design procedures
at the stages of equipment commissioning and its adjustment during the implementation
of operations. Materials and methods. Studies are presented that allow developing
methodological approaches and creating models for determining adjustment parameters
when performing centerless grinding operations. Their difference from the known ones lies
in taking into account the contact points of the treated surface and the elements of the technological
system that are constantly changing during processing. The spatial location of the
contact points in the working area determines the circuit of the power closure of the centerless
grinding and is a determining factor in ensuring the quality of processing. Results. Dependences
are derived that allow, based on the established dimensional relationships between
the tuning parameters and the characteristics of the grinding and driving wheels, the
plane of the support knife, to determine the contact points in all cross-sections in the processing
zone. Verification of the developed dependencies allowed us to confirm their operability
and improve the quality of work during equipment commissioning. Conclusions.
The models described in the article expand the formalized component of the methodological
support of technological training and are a necessary link in the creation of an automated
planning system for operations performed on centerless grinding equipment.
