This paper reports the machinability studies on aluminium hybrid composites of different compositions by using abrasive water jet machining process. In this study, aluminum hybrid metal matrix composites (HMMCs) with 5%, 10% and 15% Boron Carbide (B₄C) and 5% Zirconium Silicate (ZrSiO₄) with Al 6063 were fabricated using stir casting method. The cutting experiments were carried out by varying the water jet pressure, traverse rate, abrasive flow rate, and abrasive mesh size, and their effects on depth of cut (DOC), material removal rate (MRR) and surface roughness (R_a) were analyzed. Experiments were designed by using Box-Behnken response surface design, and the results were analyzed with response surface plots. In addition, the detailed surface evaluation studies were carried out by using 3D surface topography and morphology descriptions. Regression equations were developed to determine the significant factors in HMMCs. ANOVA test results were established for checking model adequacy in HMMCs with various responses. The results indicated that the proportion rate of B₄C with ZrSiO₄ ceramic particles in Al6063 affects the machinability and surface quality features. Also, the abrasive mesh size was found to be the responsible factors for higher DOC, MRR and lower R_a in HMMCs. The machined surface of hybrid composites shows the ploughing effect and cavities indicating both ductile and brittle fracture mechanisms.

本文报道了采用磨料水射流加工工艺对不同成分的铝杂化复合材料的切削性能的研究。在本研究中，采用搅拌铸造法制备了含5％，10％和15％碳化硼（B ₄ C）和5％硅酸锆（ZrSiO ₄）和铝6063的铝杂化金属基复合材料（HMMC）。通过改变水射流压力，横向速度，磨料流速和磨料筛孔尺寸以及它们对切削深度（DOC），材料去除率（MRR）和表面粗糙度（R _a）的影响来进行切削实验。）进行了分析。实验使用Box-Behnken响应面设计进行设计，并使用响应面图分析结果。此外，通过使用3D表面形貌和形态描述进行了详细的表面评估研究。建立了回归方程以确定HMMC中的重要因素。建立了方差分析测试结果，以检查具有各种响应的HMMC中的模型是否足够。结果表明，Al6063中B ₄ C与ZrSiO ₄陶瓷颗粒的混合比例影响切削性和表面质量。同样，发现磨料筛孔尺寸是导致较高DOC，MRR和较低R _{a的原因。}在HMMC中。杂化复合材料的机加工表面显示出耕作效果和孔洞，表明韧性和脆性断裂机制。
