Background. The object of research is the design of machining operations. Subject of research is the developing of the operation structure implemented on the turning equipment group. The purpose is to develop the models and methods for the formalization of the design procedures related to the generation of the possible options, the elimination of the non-rational and the choosing of the rational options of the machining operation structures.
Materials and methods. The mathematical formalism of Petri nets and graph theory was used to develop the models and techniques.
Results. Three mathematical models was created that describe the processes of development of the machining operation structures for the turning equipment group. The techniques was developed for the elimination of the non-rational and the selection of the rational options of the machining operation structures.
Conclusions. The developed models and techniques can be used to create the algorithms and computer programs that fully automate the development of machining operation structures for turning equipment groups. It leads to the reduction in the time and improve the quality of the design.
