Abstract

<p>The EMAF (Magnetic Abrasive Finishing combined with Electrolytic) process was proposed in order to improve the finishing efficiency of traditional MAF (Magnetic Abrasive Finishing) process. For the purpose of making EMAF process more widely used in industry, the machining mechanism of the EMAF process for finishing Aluminum Alloy A5052 has been discussed in this paper. In the experimental part, firstly the finishing effect of electrolytic reaction and MAF process in EMAF process are explored respectively. Then the compound EMAF processing experimental is conducted. The processing stability of the EMAF process is evaluated by the measured processing current value curve. By adjusting the amount of iron powder to improve the EMAF processing stability, and the occurrence of short circuits can be avoid effectively. In this study, the best experimental results were obtained when using the electrolytic iron powder of 330 μm (in mean diameter) and the amount of 0.5 g.</p>
