Abstract
In order to study the highly efficient and stable cutting of computer numerical control lathe (CNC lathe), this paper established a dynamics model of chatter turning system on tool side, and analyzed the influences of the chatter stable lobes about the CNC lathe system’s overlap coefficient, cutting rigidity coefficient in unit width, main vibration system’s damping ratio, and observed the chatter effects about the chatter stable lobes in different regions by experimental methods. Research shows that the choice of the cutting speed in the stable regions can significantly increase the cutting width, and improve the efficiency of cutting.
