基于图论和模糊TOPSIS的高速切削工艺参数优化决策

o construct process case filtering collection with rational scale adaptively, and avoid the processing effect of optimal matching case is non-ideal, a high-speed cutting parameters optimization decision method based on graph theory and fuzzy TOPSIS was proposed. By analyzing the association of cases' similar feature with graph theory and segmenting MST of the weighted undirected graph, the process case filtering collection was constructed adaptively; then, to consider processing effect of process case, fuzzy TOPSIS was applied to evaluate the processing effect of candidate cases in the process case filtering collection, the optimal cutting parameters for target process problem was obtained. The experimental results validate the feasibility and effectiveness of the proposed method.
