DYNAMIC SELF-ORGANIZATION IN CUTTING PROCESS EVOLUTION

This paper differs from the well-known works in the field of cutting process dynamics concerned with stability of the shape-generating tool paths relative to the workpiece, and with attracting sets formed in the vicinity of such paths, in that it contains the results of studies of the variation in the properties of the cutting system in the course of its evolution. In this case, for the purposes of study of the system's modification, the dynamic link parameters are presented as Volterra integral operators of the second kind relative to the phase-plane trajectory of power as a function of work. We offer a method of study of the evolution equations based on digital models, as well as methods of identification of the integral operators' parameters and nuclei. The studies are aimed at prediction of the variation in the dynamic modes and at construction of systems for dynamic diagnostics of the cutting process state.
