Previous studies found that effectiveness of EVC increases with the excitation frequency and the amplitude of vibration as well. To further optimize the EVC process the effect of the tilt angle of an elliptical tool trajectory on the machining quality was investigated. The tilt angle was modified by modulating relative magnitude and phase of voltages supplied to two piezoelectric materials constituting an elliptical vibration cutting mechanism. From successive V-grooving experiments involving duralumin and brass materials with cutting depth down to 5 μm from 30 μm, it was found that there exists an apparent correlation between the tilt angle and machining quality. At a tilt angle between 20 ∼ 30°, the cutting resistance was a minimum, leading to enhancement of machining quality. The increase in reverse frictional force between the chip and rake face of cutting tool appears to cause the cutting resistance to decrease.
