機械のアセンブリ計画の自動生成 （第２報） システムの実現

Abstract

This paper describes a detailed implementation of the automatic assembly plan generation system of which formalization as disassembling sequence generation has been given in the previous report. The disassembling procedure is composed of two phases which are called a dismounting phase and a transferring phase of a part or a set of parts. In a dismounting phase Part_Interfaces are cut moving each part to the position at which the part is separated from its “parent” part in the Plan Tree which is heuristic partial order introduced in the previous report. In a transferring phase each part is transferred to the outside of the assembly. Both of these phases are composed of moving direction selections and moving distance selections. Candidates of directions and distances are selected among Conceptual Vectors which are the local coordinates of the authors' design object modeller CONMOTO. The total disassembling problem solver has a hierarchical structure and is implemented in NODE language which has been developed by the authors and is much suited to retrieve actions in hierarchical backtracking. Some examples are shown finally.
