摘要

本文研究了磨料水射流(AWJ)加工工艺参数(射流操作压力、进给量、磨料浓度和超氧化物歧化酶(SOD))对石墨混合玻璃纤维增强聚合物(GFRP)复合材料加工过程中表面粗糙度的影响。采用田口L27正交设计进行了实验，并对工艺参数进行了优化，获得了较高的表面光洁度。采用方差分析(ANOVA)对实验数据进行分析，结果表明，操作压力和SOD的增加分别使表面粗糙度降低了15.90%和9.22%。建立回归模型对表面粗糙度进行预测，结果表明，预测值与实验值吻合较好，误差为6.57%。

Effect of process parameters on the surface roughness generated on graphite laced GFRP composite by AWJ machining

In this research paper, the effect of abrasive water jet (AWJ) machining process parameters such as jet operating pressure, feed rate, abrasive concentration and standoff distance (SOD) on the surface roughness produced during machining of graphite mixed glass fibre reinforced polymer (GFRP) composite is investigated. Experiments were conducted using Taguchi's L27 orthogonal array design and the process parameters were optimised to obtain high surface finish. Experimental data were analysed using analysis of variance (ANOVA) which shows that the surface roughness decreased by 15.90% and increased by 9.22% for the increase in operating pressure and SOD respectively. Also, regression model is developed to predict the surface roughness and found that the predicted values are in close agreement with the experimental values (error 6.57%).
