A study of Magneto-Rheological Fluid (MRF) Boring Bar For Chatter Stability
نویسنده
چکیده
Chatter is a concern in boring process, due to the low dynamic stiffness of long cantilever boring bars. Chatter suppression in machining permits higher productivity and better surface finishes. The MR fluid, which changes stiffness and undergoes a phase transformation when subjected to an external magnetic field, is applied to adjust the stiffness of the boring bar and suppress chatter. The stiffness and energy dissipation properties of the MR fluid boring bar can be adjusted by varying the strength of the applied magnetic field. The focus of this research work is to design and develop the magneto-rheological fluid (MRF) boring bar and test the same for chatter stability during boring process.
