The article considers the task of alignment of trajectories of machine executive elements set by CNC-system with evolutionarily changing properties of the cutting process in such a way that minimize the wear intensity. Consequently not position optimizes in the space of the technological regimes but its trajectories are harmonized with changes of the properties of the manufacturing process. The definition of trajectories is considered from the point of view of synergetic mutually agreed interaction of external control and internal dynamic of the cutting system. The study of alignment is performed on the basis of constructing mathematical models of a controlled dynamic system and performing digital experiments for a cutting system, the parameters of which and tool wear depend on the phase trajectory of the power of irreversible energy transformations in the cutting zone. Based on the research, new directions for improving the efficiency of cutting processes on CNC machines are proposed, which allow increasing the productivity of the cutting process without changing the requirements for the quality of manufacturing parts.
