- Abstract
Process damping significantly improves the machining stability in the low speed cutting process. Just because of this, it plays an important role in the avoidance of chatter vibrations for the situations in which the relatively low cutting speeds have to be used. Recently, more and more efforts have been focusing on process damping modeling. Unfortunately, from the existing models it can be seen that although aiming at the same physical or geometric features, different analytical formulas or extremely discrepant calibration results were obtained. Many famous scholars even listed it as the most challenging problem needed to be solved in the field of machining chatter. So the internal relationships between these models need to be deeply explored. To this end, this article reviews the mechanism and modeling of the machining process damping. Research progresses related to three typical processes, i.e., ploughing-based process damping model, velocity-based process damping model, unified process damping model, together with stability analysis with the considering of process damping are reviewed and introduced in detail. Especially, the ploughing-based process damping model as the most important part is detailed in the aspects of calculation of indented volume and calibration of ploughing force coefficients. The logical relationships between the development of each model are clarified. Several remaining problems are analyzed and the future trends of process damping modeling are summarized.
