Systemic analysis of models of dynamic systems of shaft machining in elastic-deformable condition

The paper presents methodology of developing models of dynamic systems of machining shafts in the elastic-deformable condition. The specifics of dynamic system (DS) identification concerning straight turning and straight and plunge grinding of low-rigidity shafts is presented. The specifics of the process of lowrigidity elements machining is taken into account through the introduction of suitable equations of constraint reflecting additional elastic strain in one of the equations describing the control force effect. Systemic analysis of the developed models is performed, and their hierarchical structure is given.
