摘要

<div class="section abstract"><div class="htmlview段落">由铝和其他材料制成的复合材料现在是各种工程任务的必要材料，包括汽车工业中的工程任务。本文报道了Al - 6061杂化金属基复合材料(HMMC)的可加工性研究。在合适的条件下，采用搅拌铸造法制备了碳化硼和纳米石墨烯增强Al6061合金的复合材料。针对传统加工方法难以加工的特点，选择了先进的电火花加工方法来加工HMMC。对搅拌铸造Al-B<sub>4</sub>C-GNP复合材料进行了电火花加工性能研究。以脉冲开启时间、脉冲关闭时间和峰值电流为输入参数，采用L27正交法对电火花加工工艺参数进行优化，考察材料去除率和表面粗糙度的响应。为了确定参数对测量响应的显著性，采用gray - taguchi方法进行方差分析(ANOVA)，并确定对输出响应影响最大的参数。</div></div>

Application of Grey Taguchi Method for Optimization of EDM Process Parameters on Stir Casted Aluminium Hybrid Metal Matrix Composites

Composites made of aluminium and other materials are now essential materials for a variety of engineering tasks, including those in the automotive industry. The present work reports on the machinability studies of Al 6061 hybrid metal matrix composites (HMMC). For the investigation, Al6061 alloy is reinforced with Boron carbide and Graphene nanoparticles (GNp) and the hybrid composite was prepared by stir casting under suitable conditions. The Electrical discharge machining (EDM), advanced machining process, was chosen to machine HMMC as it is difficult to machine by conventional machining. EDM machinablity studies were done on stir casted Al-B₄C-GNP composites. The optimization of EDM process parameters were carried out using L27 orthogonal approach with input parameters such as pulse on time, pulse off time and peak current for the response of material removal rate (MRR) and surface roughness. To identify the significance of parameters on measured responses, the analysis of variance (ANOVA) has been done using Grey-Taguchi method and the most influential parameters for the output responses were determined.
