Study on Part＇s Set--up Planning Algorithm in CAPP
英文摘要
Aiming at the set-up planning problem in computer aided process planning, a novel automatic set-up planning model for the prismatic part was present on the basis of definition of machining element, and a fuzzy clustering method for solving the model was proposed. From the perspective of process decision-making, these related factors affecting the machining element clustering were analyzed, such as the processing equipment, tool approach direction, process constraints etc. , then the fuzzy similarity among machining elements was calculated. A net-making method was applied to cluster the machining elements of a part in various set-ups based on the set-up similar relation matrix; following the principle of minimum number of cutter changes, the machining elements clustered in the same set-up were sorted according to precedence relationship graph. Finally several case studies show that the proposed method is feasible.
