Quotient Space Theory based Granularity Computation Method of Reconfigurable Machine Tools

Abstract:

The paper presents a new method about the granularity computation of reconfigurable machine tools based on quotient space theory for improving the response of quick structure configuration layout of manufacture system. Decomposition behavior of dynamic systematic structure is depicted by quotient space theory of the granularity intuitively and formally, which can meet different requirements through the transform of coarse granularity to fine granularity. The quotient space theory of the granularity is adopted to achieve quick granularity decomposition and combination physics implement of systematic structure model in system configuration layout, the creativity function decomposition and structure matching model is set up with the aid of the quotient space theory. It expresses granular correlative features of the configuration layout of reconfigurable machine tools roundly and corresponding correlative variety of aim assignment, and quick optimized decomposition technology of module of reconfigurable machine tools is realized. Finally, the method is verified by a case study.
