Since surface finishing is a necessary process to meet various requirements in a manufacturing stage, numerous finishing method have been studied to improve the surface integrity. In particular, use of magnetic energy has been developed due to benefits for complex surface. However, it is an immature technique for non-ferrous materials due to low permeability, and also it is the time-consuming process for large area, which is caused be low finishing rate. To overcome drawbacks of magnetic finishing methods, this study suggests a magnetic pin polishing (MPP) process affected by combined magnetic and kinetic energy. According to analysis of experimentation, surface roughness improved due to pin’s dynamic motion which is generated by magnetic force and torque in presence of the magnetic field.

用于改善磁针抛光中表面完整性的磨料的行为特性

由于表面精加工是满足制造阶段中各种要求的必要过程,因此已经研究了许多精加工方法以改善表面完整性。特别地,由于对复杂表面的益处,已经开发了磁能的使用。但是,由于导磁率低,所以对有色金属材料是不成熟的技术,并且对于大面积加工是费时的,因此加工速度低。为了克服磁性精加工方法的缺点,这项研究提出了一种受磁能和动能共同影响的磁针抛光(MPP)工艺。根据实验分析,由于销的动态运动而改善了表面粗糙度,销的动态运动是在磁场存在下由磁力和转矩产生的。
