Abstract

Study of machining characteristics is an important phenomenon of any material; the confirmation of good surface finish can justify the materials application and its usage conditions. The ultimate aim of the automobile industry is providing good mileage with highest safety. In this virtue, the material selected by light weight is very strong. This can be achieved by using the aluminum alloys materials and machined by Electrical Discharge Machines (EDM). In this research work the aluminum alloy 6063 is used as base material and 9 weight percentage of nano-SiC (Silicon carbide) powder is used as a reinforcement with 3 weight percentage of graphite (Gr) is used for the improvement of the aluminum hybrid composite material which is fabricated by using stir casting method. The mechanical properties and microstructures were studied; the machinability characteristics were studied in the EDM and optimized the process parameters by using Taguchi technique with usage of L9 orthogonal array.

利用响应面方法优化放电加工搅拌铸造 AA6063/纳米碳化硅与石墨混合复合材料的参数

研究加工特性是任何材料的一个重要现象；确认良好的表面光洁度可以证明材料的应用及其使用条件。汽车工业的最终目标是提供良好的行驶里程和最高的安全性。因此，选择重量轻、强度高的材料。这可以通过使用铝合金材料和放电加工机（EDM）来实现。在这项研究工作中，使用铝合金 6063 作为基体材料，并使用 9 重量百分比的纳米碳化硅（SiC）粉末作为增强材料，同时使用 3 重量百分比的石墨（Gr）来改进铝混合复合材料，该材料是通过搅拌铸造法制造的。对其机械性能和微观结构进行了研究；研究了电火花加工中的可加工性特征，并通过使用 L9 正交阵列的 Taguchi 技术对工艺参数进行了优化。
