非常规加工方法之一,磁粒研磨(加),提供了一个高度的表面质量和本质上是由磁场。在加,工件之间保持N和S磁铁的两极。磁性磨料粒子分散在整个工作空间和工件之间的磁铁。因为磁场的影响在工作差距,磁性磨料刷(MAFB)创建灵活和功能多点刀具。为了确定过程参数对表面质量的影响,本研究调查理论上平面加过程。使用一个有限元模型,模拟磁场。薄片的表面将成为磨料由于磁性磨料粒子在磁场下的持续运动。1毫米厚的铜表都用于实验。电流(0.25,0.5,0.75),coil-turning速度(测量磁性磨料粒子的速度运动)(20、30和40 mm / s),实验特点和流程持续时间(1、2和3小时)。研究进行了自由和棉被。 The outcomes indicate that it is simple to concurrently produce various surface roughness patterns in various directions when applying a transmission magnetic field in the MAF (TMAF). While the surface roughness of the L-shaped object is about 0.9 m in one portion of the object where the electric current is 0.25A, it is approximately 0.55 m in the other section where the electric current is 0.75A. In the meanwhile, TMAF enables the finishing of a free-form surface without the use of specific fittings. Additionally, there is an immediate correlation between the change in surface roughness, the electric current, and the processing time.
