First, when developing mathematical models of the processes of shaping by cutting, an approach based on numerical and simulation modeling was used, and experimental design methods and regression analysis were used to determine some empirical parameters of the models. Secondly, in developing dynamic models of spindle units, a systematic approach was used, which considers the spindle unit as a complex system taking into account the cutting process and the surrounding elements of the entire technological processing system. Thirdly, in the search for innovative solutions for machining composite materials, the experimental research method was used to verify effectiveness and establish adequacy. The theoretical foundations of controlling the cutting process have been created, aimed at solving the optimization problem. The basics of control by a posteriori information have been developed, involving the use of the capabilities of modern CNC machines, software has been created to automate the design of adjusted machining paths, virtual-based, which have been practically tested on machines of a turning and milling group, in particular ST-20 MF-3 HAAS. The developed generalized dynamic model of machine-tool spindle assemblies as a complex mechanical oscillatory system is used as a theoretical basis for creating new, more advanced methods for assessing the dynamic state of spindle assemblies. Created innovative technologies for machining composite materials provide for the use of new tooling, which was developed for drilling operations with process optimization and the expansion of functional and technological capabilities.
