Electrical discharge machining (EDM) has several advantages, such as the capability of machining all conductive materials regardless of their hardness and the ability to deal with complex shapes. In EDM, the machining speed largely depends on the probability and efficiency of the electrical discharges. To obtain a stable electrical discharge, it is necessary to maintain a suitable gap between the electrode and the workpiece. In this study, a five-degree-of-freedom (5-DOF) controlled, long-stroke maglev actuator is developed to allow the rapid positioning of the electrode and improve the machining speed, and the actuator can be sufficiently compact to be attached to conventional electrical discharge machines.
