Simulation and Experimental Study on Material Removal Mechanism and Removal Characters of Ultrasonic Machining

The UltraSonic Machining (USM) process is simulated by using Smoothed Particle Hydrodynamics (SPH) numerical simulation method. The influences of abrasive shape on material removal and abrasive wear are investigated. According to the simulation results, the abrasive shape has a strong influence on USM process. Using the abrasive with round shape is helpful to improve the machining efficiency. Experiments were also conducted to verify the SPH model. The experimental results agreed well with the simulation results.
