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 کامل5-axis High Speed Milling Optimisation
Manufacturing of free form parts relies on the calculation of a tool path based on a CAD model, on a machining strategy and on a given numerically controlled machine tool. In order to reach the best possible performances, it is necessary to take into account a maximum of constraints during tool path calculation. For this purpose, we have developed a surface representation of the tool paths to m...
متن کاملlook-ahead nurbs-ph interpolators for high speed cnc milling
various methods for parametric interpolation of nurbs curves have been proposed in the past. however, the errors caused by the approximate nature of the nurbs interpolator were rarely taken into account. this paper proposes an integrated look-ahead algorithm for parametric interpolation along nurbs curves. the algorithm interpolates the sharp corners on the curve with the pythagorean-hodograph ...

متن کاملEnvironmental Burden Analysis Due to High Speed Milling
The reduction of environmental burdens is required to mitigate global warming, ozone layer depletion and etc. in manufacturing fields. Hence, prediction system of environmental burden for machining operation has been developed based on LCA (Life Cycle Assessment) policy in this research. The prediction system can evaluate cutting conditions from the view points of environmental burden due to el...
