In this paper, a preventive maintenance scheme for a rotary ultrasonic vibration-assisted EDM machine is investigated. A preventive maintenance cost optimization model for machine tools was developed under the constraint of reliability. The model is simple and efficient and can be applied to rotary ultrasonic vibration-assisted EDM machine tool. The mathematical model is based on Particle swarm optimization, which is solved by MATLAB to compare the differences in optimization results under different iterations, and the optimal preventive maintenance interval for the machine tool is 417 hours according to the constraints, corresponding to a minimum maintenance cost of ¥24088, which effectively reduces the downtime loss and maintenance cost caused by the failure of machine tools, and provides a theoretical basis for the preventive maintenance plan of machine tools.

The e ciency and accuracy of conventional electrical discharge machining (EDM) is limited by the stability of the voltage between the poles. To improve the e ciency of EDM, this paper proposes a machining method that combines a self-developed 5-degree-of-freedom (5-DOF) controllable magnetic levitation actuator with a conventional EDM machine tool. The stability of the inter-pole voltage is improved by the actuator micro-adjustment the electrodes of the EDM machine tool. Firstly, an EDM control system with local current feedback and decoupling control elements is designed based on the EDM servo drive principle to improve the response speed and positioning accuracy of the actuator. Secondly, the actuator was connected to the spindle of a conventional EDM machine tool, and machining experiments were carried out. The experimental results showed that the EDM machine tool connected to the actuator could control the electrode position more quickly, adjust the discharge state quickly, and increase the number of discharges per unit time. The average machining speed increased from 1.108µm/s to 3.925µm/s, which is 3.54 times faster than conventional EDM. Finally, complex shape machining experiments were carried out and the machining results showed that by adjusting the target value of the radial direction of the actuator, the various trajectories of the electrode could be controlled to depict arbitrary shapes.
