Innovative technologies and machine tool equipment for highly productive cutting by cutting modern structural materials

When implementing the project, a comprehensive research structure was applied, in which the choice of a specific type of research was determined by the goals and objectives that were solved at individual stages of its implementation. 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.

Development of environmentally cleaner technologies for producing composite materials based on nanocellulose, microcrystalline and oxycellulose from domestic plant materials

It was found that cereal stems and industrial plant fibers contain more minerals than wood, which must be taken into account in the pulping process.
