This paper presents a new method of reconfiguring the whole machine tool configuration design in the whole life cycle of the machine tool (part mixing and production) and generating an economical configuration path through all the requirements of the entire life cycle. The machine tool cost model of fixed demand phase is established, and the optimal configuration of reconfigurable machine tool in fixed demand phase is obtained by using integer linear programming method. The concept of reconfigurable machine tool configuration similarity is proposed. Based on this, the improved genetic algorithm To generate reconfigurable machine configuration options for fixed demand phases; to evaluate reconfigurability by calculating machine configuration similarities between adjacent demand phases; and to re-use improved genetic algorithms to obtain all requirements for the entire life cycle of reconfigurable machine tools Optimal allocation of stages of the path.
