Stability analysis for a single-point cutting tool deflection in turning operation

Advances in Mechanical Engineering, 2019
In this article, a new model of regenerative vibrations due to the deflection of the cutting tool in turning is proposed. The previous study reported chatter as a result of cutting a wavy surface of the previous cut. The proposed model takes into account
