For difficult-to-cut materials, Nath and Rahman proposed ultrasonic-vibration-assisted machining as an efficient cutting method, to reduce the cutting force, suppress tool wear, and ensure tool life and surface quality [2].
Several researchers [3, 4] have experimentally shown that ultrasonic-vibration-assisted machining improves the machinability of several materials, such as aluminum alloys, Inconel, and composite materials.
Neugebauer et al. reported that ultrasonic-vibration-assisted cutting can extend tool life because the fracturing effect reduces the cutting force while drilling hard and brittle materials such as glass and ceramics [5].
