【Abstract】 In order to improve the quality and efficiency of micro-WEDM,ultrasonic vibration is applied to the workpiece,which is used to modulate pulse discharging. The effects of ultrasonic modulate pulse discharging for the quality and efficiency of micro-WEDM is analyzed. Experimental studies have shown that ultrasonic vibration have significant effect on increasing spark erosion,reducing the short-circuit,increasing processing efficiency and stability and improving quality.更多还原
