中文摘要 | 磁力研磨加工乃是利用磁性磨粒受磁力驅使聚集成磁力刷作用在工件表面,並藉由磨粒與工件問之相對運動產生研磨的加工效果。由於磨粒在工件表面的加工量相當小,因此可形成近似鏡面品質的加工表面,與傳統輪磨加工比較,磁力研磨加工所使用之磨和並非實體工具,可適應工件表面複雜的輪廓外形,所以對現今微細複雜機件的精修加工應用,亦提供了相當有效的加工效能。甚至對現今愈來愈成熟發展的奈米加工技術的應用,磁力研磨加工亦展現了相當引人注目的發展潛力。本研究主要在建構磁力研磨精修加工機構,並以此加工機構對管件材料中廣泛使用的SUS304不銹鋼內孔表面,進行磁力研磨精修加工的實驗探討。研究中選定磨粒混合比、磁通 密度、加工時間、主軸轉速等實驗參數,探討磁性研磨加工參數對材料去除量及表面粗糙度等加工特性的影響。經由加工表面精修效果的分析探討,釐清磁力研磨加工參數對加工特性的影響,以建立快速、高精度及高品質的表面精修技術,以滿足現今產業對表面加工品質的需求。 |
英文摘要 | Magnetic abrasive machining (MAM) removed material by a magnetic bush that made of magnetic abrasives constrained by a magnetic force. During the machining process, the magnetic abrasives have a relative motion to the workpiece surface so the MAM acts as a grinding process. Since the amount of the removed material caused by each magnetic abrasive is very small, the MAM could produce a mirror-like machined surface. Compared with traditional wheel grinding, the magnetic abrasive of MAM is not a rigid tool to fit the complex profile of components. Therefore, the MAM can be adopted in the application of the micro machining, even though in the development of nano-technology, the MAM also presents the most promising potential to be employed. The purpose of this study is to set up the machining device of MAM. Furthermore, the finishing characteristics of inner wall with the SUS 304 stainless steel were conducted using this device. In this investigation, the machining parameters such as mixture ratio of magnetic abrasive, magnetic fluxdensity, machining time and rotational speed are chosen to determine their effects on finishing characteristics of internal surface. The finishing characteristics including material removal (MR), surface roughness are explored. This study intends to investigate the relations between the surface finishing and machining parameters. Moreover, a finishing process with high efficiency, precision and high quality surface will be established to satisfy the demands for modem industrial applications. |
