【Abstract】 Machine tool selection is the key problem in CAPP system design. In this paper the machinetools were divided into different groups and layers in tree structure. The selection of machine tool wasdescribed with generating rules and the algorithm was also given. At the end of this paper, the conflictregulation tactics ware put forward.更多还原
