Thus, it is important to ensure machining for these parts are done in a high precision manner. Ultrasonic vibration assisted milling (UVAM) is a well-known precision machining equipment.

A commercially available cutting tool manufactured by HPMT with a diameter of 6 mm and featured with differential pitch was used in this research. The ultrasonic vibration generator excites the workpiece with a frequency in the range of 9~18 kHz and an amplitude of 0.5~3 μm.

The results showed that a considerable improvement was identified in UVAM. It was found that end milling with ultrasonic vibration in the feed vibration of 18 kHz with an amplitude of 3 μm was able to reduce 13%(Fx) and 18%(Fy) of cutting force, reduce 18.4% of cutting temperature and improve the surface roughness up to 60% as compared to CM.
