Study on Grinding Force Model in Ultrasonic Vibration Assisted Grinding for Ductile materials

摘要

Ultrasonic vibration Assisted Grinding (UAG) is an effective processingmethod for difficultmachiningmetalmaterial.This paper put forward a new model to predict the grinding force in UAG. The paper presents the abrasive grain motion equations, removal rate model,grinding force model and grinding force ratio model. According to the grinding force model, the grinding force will decrease as the spindle speed, vibration amplitude and vibration frequency increase. The grinding force increase as the grinding depth and feed rate increase.
