...Aaron Cornelius; Jaydeep Karandikar; Chris Tyler; Tony Schmitz Process damping can provide improved machining productivity by increasing the stability limit at low spindle speeds. While the phenomenon is well known, experimental identification of process damping model parameters can limit pre...

... packed with short wavelengths. This paper presents an analytical model to predict the process damping forces and chatter stability in low-speed machining operations. The indentation boundaries are evaluated using the cutting edge geometry and the undulated surface waveform. Contact pressure due...

... force coefficients are identified either using previously presented slip-line field or finite element methods by considering the effects of chip size, cutting edge radius, rake angle and cutting speed. The process damping caused by the plowing of round edge is modeled by finite element method...

...L. T. Tunc; E. Budak The experimentally identified stability limits are presented in Fig. 10 . In most of the cases, the significance of process damping on stability limits can be observed until 100 m/min of cutting speed, similar to the results obtained in orthogonal cutting [ 18 ]. However...

...E. Budak; L. T. Tunc Although process damping has a strong effect on cutting dynamics and stability, it has been mostly ignored in chatter analysis as there is no practical model for estimation of the damping coefficient and very limited data are available. This is mainly because of the fact...

...C. Y. Huang; J. J. Junz Wang This paper extends analytical modeling of the milling process to include process damping effects. Two cutting mechanisms (shearing and plowing mechanisms) and two process damping effects (directional and magnitude effects) are included. The directional effect is related...
