Surface roughness is one of the important factors which help to address the quality needs of composite materials, and it relies on the machining conditions. This paper carried out an experimental investigation to identify the influence of machining parameters on surface roughness of aluminum metal matrix composites. Stir casting technique is used to produce SiC- and B4C-reinforced aluminum composites with three different compositions. Using end mill cutter, the materials are machined with different combination of machining parameters. To assess the quality of machined surface, roughness of machined surface is measured with the help of surface roughness testing machine. The obtained results have been analyzed to optimize cutting parameters using Taguchi and ANOVA techniques. The experimental results confirm the order of most influential milling parameters as 0.1 mm/rev feed rate, 3000 rpm spindle speed and 0.2 mm depth of cut with maximum contribution percentages of 86.6%, 9.75% and 6.16%, respectively. This study would ensure the optimal parameters for quality products in terms of surface roughness.

铣削参数对Al–SiC–B 4 C复合材料表面粗糙度的影响

表面粗糙度是有助于满足复合材料质量要求的重要因素之一,它取决于加工条件。本文进行了实验研究,以确定加工参数对铝金属基复合材料表面粗糙度的影响。搅拌铸造技术用于生产SiC-和B 4具有三种不同成分的C增强铝复合材料。使用立铣刀,可以用不同的加工参数组合来加工材料。为了评估加工表面的质量,借助表面粗糙度测试仪测量加工表面的粗糙度。使用田口和方差分析技术对获得的结果进行了分析,以优化切削参数。实验结果确定了最有影响的铣削参数顺序为0.1 mm / rev进给速度,3000 rpm主轴速度和0.2 mm切削深度,最大贡献百分比分别为86.6%,9.75%和6.16%。这项研究将确保就表面粗糙度而言,优质产品的最佳参数。
