An investigation of ultrasonic nanocrystal surface modification machining process by numerical simulation
A simplified model of UNSM was developed by equivalent static loading method. A 3-D model was built to investigate the machining process of UNSM. Small and stable energy dissipation of UNSM process can be found. Lower machining linear velocity can produce severe surface work hardening. Static loading has a greater impact to UNSM result comparing others.
