A Review of Chatter Analysis in machine tools and control methods

Metal cutting has had one troublesome obstacle in increasing productivity and accuracy namely chatter. In machining , chatter is perceived as unwanted excessive vibration between the tool and wear. It also has a tensing effect on the machine tool life ,and the reliability and safety of the machining operation. The frictional and impact chatter are mainly due to the nonlinearity of the dry friction and the intermittent contact between the cutting tool and the workpiece . There are some methods that can limit the chatter . In this paper we introduce and compare some of these methods.
