摘要

近年来,磨料水射流加工因其非热性而成为复合材料加工的一种很有前途的加工技术。本文研究了加工参数对加工质量的影响,优化了加工黄麻纤维增强聚合物复合材料的工艺参数。利用实验设计预测L27实验输入参数的组合。采用田口法(Taguchi)和响应面法(RSM)对实验数据进行分析,确定工艺参数的最佳组合,以实现尽可能少的分层。结果表明:随着横移速度和磨料质量流量的增大,所得到的损伤也随之增大。然而,参数隔离距离值的增加使所产生的损害最小化。为了实现最小分层,通过田口法和RSM法得到输入参数的最佳组合。在目前的实验条件下,为了实现最小的分层,参数穿越速度应设置为20 mm/min,距离应设置为4 mm,磨料流速应设置为0.25 kg/min。结果表明,两种方法得到的最佳参数组合是相似的。研究结果表明,通过优化工艺参数,可以显著提高切割质量,减少损伤。对于所考虑的参数范围,绘制了图形,以便在所考虑的范围内可以预测任何中间值,而无需进行任何进一步的实验。本研究揭示了纤维取向对分层的影响。

A Study to Investigate the Influence of Machining Parameters on Delamination in the Abrasive Waterjet Machining of Jute-Fiber-Reinforced Polymer Composites: An Integrated Taguchi and Response Surface Methodology (RSM) Optimization to Minimize Delamination
In recent years, abrasive waterjet machining has emerged as a promising machining technique for the machining of composites because of its non-thermal nature. In the present study, the effect of machining parameters on the quality of machining has been studied and the process parameters have been optimized to machine jute-fiber-reinforced polymer composites. The design of the experiment was used to predict the combination of the input parameters for L27 experiments. Taguchi and response surface methodology (RSM) techniques were employed to analyze the experimental data and identify the optimum combination of process parameters to achieve as little delamination as possible. The results indicate that an increase in the values of the parameters traverse speed and abrasive mass flow rate leads to an increase in the damage obtained. However, an increase in the value of the parameter stand-off distance minimizes the damage produced. To achieve minimum delamination, the optimum combination of input parameters is obtained through Taguchi and RSM. For the present experimental condition, to achieve minimum delamination, the parameter traverse speed should be set at 20 mm/min, the stand-off distance should be 4 mm, and the abrasive flow rate should be set at 0.25 kg/min. The results confirm that the optimum combination of parameters obtained through both approaches is similar. This investigation results indicated a significant improvement in the cutting quality with reduced damage, achieved through the optimized process parameters. For the considered range of parameters, graphs are plotted such that any intermediate values can be anticipated within the considered range without performing any further experiments. The present work signifies the effect of fiber orientation on delamination.
