Modulization-based method for designing reconfigurable machine tool

Abstract

The invention relates to a modulization-based method for designing a reconfigurable machine tool, including the following steps: firstly, establishing a module based on parametric design; secondly, researching a module code system, and utilizing the theory of genetic algorithm to carry out the systematic coding of each module; thirdly, carrying out the optimization design of each module to optimize the structure of each coding module; fourthly, carrying out the operation of topology, utilizing the graph theory to design the reconfigurable functional topological structure to express the topological relation of the functions, and selecting the topological structure of the reconfigurable machine tool; fifthly, automatically assembling the modules, establishing a parameterized module library according to the selected topological structure of the reconfigurable machine tool, and selecting mechanical modules from the module library to form the entire reconfigurable machine tool by assembly; and sixthly, evaluating and researching the performance of the machine tool from the aspects of technical performance and economic performance. The method fast meets the variable requirements of part manufacturing by the module configuration, and provides the redundancy-function-free machine tool, thereby realizing the optimization of function and cost.

Description

technical field [0001] The invention belongs to the technical field of computer-aided mechanical design and relates to a method for reconfigurable machine tool design. Background technique [0002] A reconfigurable manufacturing system is a manufacturing system that has the two functions of actively adapting to changes in the external environment and passively responding to internal disturbances in the system. The function and production capacity of the system can adapt to changes in product varieties or changes in market demand. The six characteristics of a reconfigurable manufacturing system are modularity, openness, scalability, integrability, transformability, customization, and diagnosability. Among them, modularity is the core feature of reconfigurable manufacturing system. The reconfigurable manufacturing system is composed of the upper-level planning and scheduling controller and the lower-level reconfigurable machine tool. As the smallest unit of a reconfigurable...
