In this research, multi response Taguchi-grey relational approach was employed to optimize the machining parameters of Ti-6Al-4V alloy in abrasive water jet process. The main aim of this present investigation was to explicate the role of adding SiC super hard ceramic into the garnet and to find out the optimal input variable, which is influencing the material removal rate and surface finish in the process. The specific input variables such as SiC volume, SiC size and abrasive flow rate were accounted as potential process variables for this present investigation. It is observed that the SiC along with garnet improves the material removal rate. According to the analysis the SiC addition of 0.5 wt.%, SiC size of 80mesh and abrasive flow rate of 2 g/s (A2B1C1) was found to be producing MRR of 48.81 mm³/s and lower surface roughness of 3.72 μm. From study the particle size was the most influential parameter for producing high MRR with low surface roughness. The confirmation study reveals the improvement of 1.91% in MRR and surface roughness on comparing with predicted mean value.

在这项研究中，采用多响应Taguchi-grey关系方法来优化Ti-6Al-4V合金在喷水过程中的加工参数。本研究的主要目的是阐明在石榴石中添加SiC超硬陶瓷的作用，并找出最佳输入变量，该变量会影响工艺中的材料去除率和表面光洁度。特定的输入变量（例如SiC体积，SiC尺寸和磨料流速）被视为本研究的潜在工艺变量。观察到SiC与石榴石一起提高了材料去除率。根据分析，发现SiC的添加量为0.5 wt。％，SiC尺寸为80目，磨料流速为2 g / s（A2B1C1），产生的MRR为48.81 mm ^3。/ s，下表面粗糙度为3.72μm。通过研究，粒径是产生具有低表面粗糙度的高MRR的最有影响的参数。确认研究表明，与预期平均值相比，MRR和表面粗糙度提高了1.91％。
