| Outline of Final Research Achievements |
In this research, a proposed 5-DOF controlled maglev actuator was attached to a conventional machine and a control system for EDM was designed. EDM experiments were carried out and the experimental results seen that the machining shapes could be adjusted in proportion to the variation of the motion trajectory of the electrode. In polishing process, to realize the motion control of a polishing tool in multi DOF directions and the polishing force control by using the proposed actuator, a hybrid motion/force control system was designed, and the polishing experiments of the rectangular and trapezoid pattern texture maps were tried using diamond tools. Furthermore, in laser cutting, to examine the influence of the laser beam eccentricity on cutting process, based on fluid dynamics, the eccentricity laser cutting process were simulated and verified by cutting experiments. The results show that the appropriate eccentricity can effectively improve the quality of the laser cutting.
