聚合物基复合材料在航空航天、国防、汽车和船舶工业中的应用日益广泛。在这些领域中，磨料水射流（AWJ）的非传统加工方法已被广泛应用于聚合物基体构件的成型。本研究采用田口实验设计，详细研究了玻璃纤维增强乙烯基酯复合材料板在不同AWJ切削参数下的性能。对于田口实验设计，实验参数的喷射距离，磨料质量流量，横向速度，压力和材料厚度被确定在三个水平。为了了解切削性能，研究了顶部切口宽度和表面粗糙度。最后，进行线性回归模型，并使用方差分析（ANOVA）和主效应图检查所有性能参数。根据总体试验结果，确定了最有效的间隔距离。通过主效应图得到最优参数水平，最后通过参数水平的最优组合对预测模型进行验证。
ABSTRACT Polymer matrix composite materials have been increasingly used in aerospace, defense, automotive and marine industries. In these fields, nontraditional machining method of abrasive water jet (AWJ) has been used significantly in order to form polymer matrix components. In this study, glass fiber reinforced vinyl ester composite plates have been investigated under various AWJ cutting parameters by using the Taguchi experimental design in detail. For Taguchi experimental design, experimental parameters of standoff distance, abrasive mass flow rate, traverse speed, pressure and material thickness were determined at three levels. Top kerf width and the surface roughness were investigated in order to understand the cutting performance. Finally, linear regression models were conducted and all performance parameters were examined using analysis of variance (ANOVA) and main effects plots. According to the overall test results, standoff distance was determined as the most effective one. The optimal parameter levels were obtained by the ‘main effects plots’, and finally, the predictive modeling was validated by performing the optimal combination of parameter levels.
