【Abstract】 After analyzing the basic ideas of hierarchical planing, subtask analysis and solution strategies, this paper presents the methods of CAPP decision based on hierarchical planning and expounds the functions and features of sub-tasks of various phases so as to establish a diagram of process planing solution. Moreover, the mechanism of process decision reasoning of hierarchical planning are discussed in detail.更多还原
