On nonlinear cutting response and tool chatter in turning operation

A review of chatter vibration research in turning

“…It was also shown that when inclination angle or nose radius exists on the tool, a multi-dimensional solution is needed since the SDoF stability formulation fails to represent the dynamics of the process accurately. Dassanayake [37] studied tool chatter with turning dynamics using a 3DoF model and also compared it with an SDoF model. In a 3DoF model the workpiece is modeled as a system of three rotors namely, machined, being machined, and unmachined regions connected by a flexible shaft.…”

“…Budak and Ozlu [35] used an accelerometer and AE sensors to verify a multi-dimensional chatter stability model which includes nose radius to the tool geometry. A sound measurement setup was used to measure the chatter frequency for comparing their SDoF and multidimensional models in [37]. Yu et al [94] found that when chatter occurs, significant vibrations in the system are established which can be detected using the sound pressure level from a microphone to determine precise chatter frequency.…”

A hybrid decision making approach to prevent chatter vibrations

“…Seguy and Seguy [14] proposed a methodology of decision support for preventing chatter during milling operation. The turning process can be modelled according to the number of degrees of freedom (DOF) [15][16][17][18][19], tool and workpiece flexibilities [20][21][22] and tool wear and process damping [23][24][25]. A number of authors have used Nyquist plots and finite element analyses [26][27][28][29] and have performed experiments measuring force and vibration in an attempt to predict chatter stability [18,22,[30][31][32][33].…”

Nonlinear analysis of chatter in turning process using dimensionless groups

“…Most of the 3-D models have not considered torsional and gyroscopic effects. For instance, Dassanayake and Suh [16] studied tool chatter in turning using a 3DoF model. In their 3DoF model, the workpiece is modeled as a system of three rotors namely, machined, being machined and unmachined regions connected by a flexible shaft.…”
