The mechanism of material removal in usm is brittle fracture. Tool material should be soft. Material removal depends of flow rate of abrasive particles, size of abrasive. And material removal rate is maximum in edm and less in ebm.

Ultrasonic machining is a slow process so it can't remove large amount of materials. Now a days piezo crystals are used in ultrasonic machining.
