摘要
Abstract
The extrusion velocity(A),filling velocity(B),layer thickness(C) and filling pattern(D) are selected as the controlling factors in fused deposition modeling (FDM).Firstly,the influencing degree of the process parameters on the single index such as length deviation rate,width deviation rate and porosity is determined by orthogonal experiment,considering the interaction between the controlling factors.Then the experimental results are comprehensive evaluated based on the entropy-weight technique for order preference by similarity to an ideal solution (TOPSIS) model and the relative closeness is used as the comprehensive index.Combining the range analysis and variance analysis,the influencing degree of the process parameters on the comprehensive index and the optimal combination of processing parameters is determined.The experiment results show that the filling pattern,filling velocity,the interaction between extrusion velocity and filling velocity,has a strong influence on comprehensive index,and the optimal combination of the processing parameters is A1B3C1D1.Besides,a verification test is carried out and shows that the optimization scheme of the comprehensive index is improved by 2.25%.关键词
