FMA结构化分解驱动的加工中心设计过程规划
Machining Center Design Process Planning Driven by FMA Structural Decomposition
摘要
Abstract
To better realize the design of a machining center,reduce its iterative time and shorten its development cycle,the FMA (Function-Motion-Action) structural decomposition was used to decompose the machining center into its corresponding meta-action step by step according to the order of the FMA,the definitions of meta-action design structural unit were given on the basis of considering the coupling among design units,and the machining center design process planning driven by FMA structural decomposition was put forward.Then the double indexes for sensitivity and variability were introduced to express the coupling degree among design units,the design structure matrix was used to quantify the coupling strength among design units,and the tearing planning based on the index order was used to tear the coupled design units,thus the initial design sequence of design units was determined,and the machining center design process planning was implemented and can accelerate the design and development of the machining center.Finally,the automatic pallet changer of a machining center was taken as an example to prove the effectiveness of this paper.关键词
