摘要:<正>Implementation of augmented spindles to Wire Electrical Discharge Machining(WEDM) and EDM Grinding(WEDG) processes with very thin wire are reported.On its analysis,the proposed analysis based upon WEDM discharge angle was introduced to clarify fundamental understanding of material removal mechanism.Cylindrical WEDM shaped contours were basically conjugated to the wires relative movement with respect to the revolution axis.The proposed analysis provided a better understanding for multi-axes WEDM,and also an useful strategy for improving both the stability and efficiency performance.On the other hand,conventional WEDG took a lot of machining time and resulted in rough surface on rod.An ultrasonic assisted WEDG system was then developed in this study;its significant effects on improving machining efficiency and surface integrity of workpiece were verified experimentally.
