Material Removal Rate Model of Ductile Materials in Ultrasonic Machining

Ultrasonic Machining（USM） is an important branch of modern ultrasonic technology, which has broad applications in machining of different types of materials. As the material removal mechanism of brittle and ductile material is completely different, so it is very critical and important to develop a mathematical model for ductile materials in USM. In this paper, base on the theory of Contact Mechanics, a novel material removal rate （MMR） model of machining ductile materials is proposed. It is found that the MMR predicted by the model is in good agreement with the cited experimental results. The research provides a theoretical basis of machining ductile material in USM, and it is also helpful for further study and practice.
