Abstract

The traditional micro-machining process is revolutionized by maglev systems, which can provide friction-free support, high precision (below 1μm), low friction wear, etc. in the machining processes of micro electrical discharge machining (micro EDM), additive manufacturing, etc. However, the interaction of tools and the workpieces will cause system parameter uncertainties, impacting the stiffness and precision of the whole system. This paper presents a review of disturbance mitigation technologies of maglev worktables between 2022 and 2025 with regard to structural design, adaptive control techniques and applying novel technologies, such as artificial intelligence (AI). As promising examples, we can also appreciate 5-DOF actuators with resolution at the level of 1 µm, the final surface roughness after micro-EDM operations improved, the rate of material removed increased. Issues remain in controlling nonlinear motions, lowering construction expense, and making devices compatible with varied manufacturing environments. Further research involves supervised-learning enabled control, cyber-physical systems, and low cost machine development for achieving higher accuracy and reliability, to realize maglev as revolutionary devices in precision manufacturing.
