Abstract

One of the most common types of lightweight materials used in aerospace is magnesium alloy. It has a high strength-to-weight ratio and is ideal for various applications. Due to its corrosion resistance, it is commonly used to manufacture of fuselages. Unfortunately, the conventional methods of metal cutting fail to improve the performance of magnesium alloy. One amongst the most common methods used for making intricate shapes in harder materials is through Wire-Electro-Discharge (WEDM). In this study, we have used magnesium alloy as the work material. The independent factors were selected as pulse duration and peak current. The output parameters of the process are the Surface Roughness (SR) and the Material Removal Rate (MRR). Through a single aspect optimization technique, Taguchi was able to identify the optimal combination that would improve the effectiveness of the WEDM process. The findings of the experimentation revealed that the technique could significantly enhance the wire-cut process’s efficiency.

田口的AZ31B镁合金线切割加工方法

<div class="section abstract"><div class="htmlview段落">镁合金是航空航天中最常用的轻质材料之一。它具有高强度重量比，是各种应用的理想选择。由于它的耐腐蚀性，它通常用于制造机身。遗憾的是，传统的金属切削方法无法改善镁合金的性能。在较硬的材料中制造复杂形状的最常用方法之一是通过线切割。在本研究中，我们采用镁合金作为工作材料。独立因素分别为脉冲持续时间和峰值电流。该工艺的输出参数是表面粗糙度(SR)和材料去除率(MRR)。通过单向优化技术，田口能够确定提高线切割加工效率的最佳组合。实验结果表明，该技术可以显著提高线切割过程的效率。</ divt;/ divt;
