Reconstruction Method of Reconfigurable Machine Tool Based on Task Polymorphism

For the problem of reconfigurable machine tools existing in the field of manufacturing and processing cost, the reconfiguration strategy of a reconfigurable machine tool (RMT) was proposed based on the analysis of polymorphism processing tasks. Firstly, the models of fixed cost and reconstruction cost in per production cycle were built. On this basis, the cost model of RMT during the whole production cycle was built. Then the Dijkstra’s algorithm was used to solve the model and the optimal reconstruction program was obtained. Finally, a RMT for the engine block production was taken as an example to verify the validity of the model and the method.
