초록
In this work the multiple moving magnetic abrasive machining (MAM) process was used to polish the surface of spherical bar that is the components that widely used in many applications such aerospace, medical implantation, and the mechanical engineering industries. The smooth surface of spherical ball plays an important role for improving the lifespan, durability, and functionality of the components. In. Therefore, the moving MAM process was fabricated to achieve high quality surface of the spherical ball sample. This process used the multiple moving actions of the machining tools for polishing the surface sample. The experiments used in this work was set as the rotational speed of sample (50, 120, and 250 rpm), movement of machining tools (X-axis: 12 mm/sec, Y-axis: 12 mm/sec), and the polishing times (0, 2, 4, 6, 8 min). The results demonstrated that within 6 min of the polishing time the surface roughness of sample was significantly reduced from 0.29 μm to 0.02 μm under the polishing action of machining abrasive tool (size: 1-μm). This can be concluded that the multiple moving MAM process is an effective method to achieve high surface quality of sample with extremely low surface roughness (Ra).
