摘要
正交法优化激光切割镍基合金的切缝宽度不是最优方案,应考虑交互作用即因素间联合作用对实验指标的影响。正交实验设计包括:确定切割质量评价指标、确定因素水平、交互作用表头设计。为了规避实验偶然性进行两组交互作用正交实验,分别采用L 8(2
7)正交表分析气压、离焦量与切速以及三者间两两交互作用对切割质量的影响,采用L 16(2
15)正交表分析切速、电流、脉宽、频率以及四者间两两交互作用对切割质量的影响。根据实验结果进行直观分析与交互作用分析对比可得:交互作用分析可以在全面实验中准确找出最优方案。总结了激光切割镍基合金时存在的、显著影响切割质量的交互作用,两组实验得出的最佳工艺参数以及实验中重要的影响因素。
Abstract
It is not an optimal solution to optimize kerf width of laser cutting Ni-based alloy steel by orthogonal method, so it is suggested to take effects of interaction, which is a combination of factors, into consideration. Design of orthogonal test include evaluation index determination of cutting quality, levels determination of each factor, interaction table top design. After that, in order to avoid test contingency, two groups of orthogonal experiments are performed. L8(2
7) table is used to analyze the effects of gas pressure, defocusing distance, cutting speed and the interaction between the factors on cutting quality, and L16(2
15) table is used to analyze the effects of cutting speed, current, pulse width, frequency and the interaction between the factors on cutting quality. Finally, according to the test results, We can get a conclusion that interaction analysis can accurately find the optimal solution in a comprehensive experiment by a contrast of intuitive analysis and interaction analysis. The significant interaction that impacts on quality of laser cutting Ni-based alloy steel is summarized. The optimum technological parameters of the two groups and important factors are obtained.
