Global Dynamics of Low Immersion High-speed Milling. Global Dynamics of Low Immersion High-speed Milling
In the case of low immersion high-speed milling, the ratio of time spent cutting to not cutting can be considered as a small parameter. In this case the classical regenerative vibration model of machine tool vibrations reduces to a simpli ed discrete mathematical model. The corresponding stability charts contain stability boundaries related to period doubling and Neimark-Sacker bifurcations. Th...

متن کاملEfficient Method for Prediction of Stability in Low Immersion Milling
This paper presents cutting force prediction algorithm for low immersion end-milling, using an efficient dynamic force modeler. The geometric simulation of milling process was performed, using the B-Rep solid modeling techniques. For predicting stability lobes, two methods were used for prediction of stability lobes: the frequency domain technique and the time finite element analysis (TFEA). Th...
متن کاملEffects of Helix Angle Variations on Stability of Low Immersion Milling
The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...
متن کاملOn Stability Prediction for Low Radial Immersion Milling
& Stability boundaries for milling are predicted by the zeroth-order approximation (ZOA) and the semi-discretization (SD) methods. For high radial immersions, the methods predict similar stability boundaries. As radial immersion is decreased, the disagreement between the predictions of the two methods grows considerably. The most prominent difference is an additional type of instability predict...
