It is desirable to minimize burr formation for improving part quality. This paper presents an investigation on the burr formation mechanism in micro cutting by taking into consideration the stress distribution around the cutting edge arc. The influences of the uncut chip thickness and the cutting edge radius on burr formation were investigated. Poisson burr is attributed to the side flow of the stagnation...
In micro cutting, both the cutting edge radius and the material grain size have a great influence on the cutting force. The study of the influence of the material grain size on the cutting force is unavoidably affected by the dual effect of the cutting edge radius. In this paper, a method for estimating the shearing force is proposed. In addition, micro turning experiments were performed to investigate...
