Particularities of Dispersed Materials Microcutting

This article presents results of research on microcutting mechanics and dispersed structure of metallopolymers. It describes dispersed materials structure and composition. Article includes experimental identification of the particularities of metallopolymers microcutting. It determines where metallopolymers cutting physics mainly differs from physics of cutting conventional steels and alloys. It is demonstrated that under enhancing dispersion of the metallopolymers, plastic cutting is almost absent; in case of grain included into solid metallopolymer inclusion, inclusion particles can stick to this grain resulting in cutting, performed by this inclusion. This document includes results of the inclusions metric parameters calculation and data on average metallopolymer matrix grain size, based on the microscopic study of metallopolymers dispersed structure. The research the authors have performed demonstrates that classical cutting theory is not applicable to metallopolymers; it is necessary to develop new models, taking into account the dispersed structure of these materials.
