| Abstract: | Based on the previous research on technology of compound ECM with constant magnetic field, rotating magnetic field with high-frequency group pulse was introduced in our ECM experiments to study the effect of directional changing of magnetic field on ECM effectiveness. The rotation of the magnetic field was controlled by eight relays and a microprocessor. With some designed orthogonal experiments, the interaction influence of multiple parameters on machining has been investigated. Experiment results show that the interaction among the factors of magnetic field rotation speed, magnetic field intensity and the machining gap would affect the machining greatly, which contributes to further research on compound ECM. |
