STRUCTURAL QUANTITATIVE PARITIES OF PROCESS CUT-FORMATION
As a result, high-speed plastic deformation accompanying the metal cutting process, according to the physical breakdown occurs mesomechanics microstructure formation and fragmented elements (clusters) on the mesoscale level, the boundaries of which carry complete information on the status and history of its development, they function as a kind of interface. Fractal dimension and density boundaries are quantitative indicators of the degree of development boundaries, but reflect the different sides of this property. The proposed method for the quantitative structural analysis allows us to trace the variation of deformation processes in the area of chip. Parameter sets of binary structure, comprising the fractal dimension and density interfaces to evaluate micro and mesostructure chips and reveals the dynamics of the deformation process and changing the media of plastic deformation in the transition from the micro to the mesoscale level. Quantitative structural analysis of chip shows that the plastic deformation to the shear zone is accompanied by grain refinement and an increase in the degree of development of grain boundaries and dissipation at the expense of dislocation dynamics and grain boundary sliding. In the shear elements are formed of fragmented chip whose density increases with increasing degree of plastic deformation. Low level of development of interfaces clusters indicates their high mobility and dissipative activity.
