摘要
研究了使用Nd∶YAG激光切割牌号为GH3128的高温合金钢过程中的工艺参数。采用正交法进行了20次试验。研究了影响激光切割质量的因素,包括氧气气压、离焦量、加工速度、输入电流、脉宽、频率及误差项。观测切割后的挂渣厚度、切缝宽度,并得到综合评价结果;采用直观分析法分析了各个工艺参数对切割质量的影响程度,得到最优工艺参数,并根据最优工艺参数进行验证试验。采用方差分析法分析了各个因素之间的交互作用及区组间差异,并研究交互作用及区组间差异对切割质量的影响。结果表明,正交法可以优化挂渣厚度和综合评价,但对切缝宽度无优化作用。
Abstract
The processing parameters for cutting the high-temperature alloy steel (the mark is GH3128) by Nd∶YAG laser are studied. Eighteen experiments are conducted by the orthogonal method. The factors which influence the quality of laser cutting, including oxygen pressure, defocusing distance, cutting speed, input current, pulse width, frequency and error, are studied. The slag thickness and the kerf width are observed after laser cutting, and the comprehensive assessment is worked out. The influence of processing parameters on the cutting quality is studied by the intuitive analysis method. The optimal parameters are obtained, and verification experiments are conducted based on these optimal parameters. Interaction effect and block-group difference among these factors are studied by the variance analysis method, and the influence of interaction effect and block-group difference on the cutting quality is studied. The results show that the orthogonal method can optimize the slag thickness and the comprehensive assessment, but cannot optimize the kerf width.
