Zusammenfassung:This present study discusses about improvement of damping capability of boring tools and suppression of chatter using Magnetorheological (MR) damper. For the design and optimization of MR fluid damper volume constrained optimization methodology using ANSYS magnetic finite element routines were executed. Optimized design of MR damper was fabricated and its effect in boring operation has been investigated using an experimental setup. Experimental results were analyzed with the help of Auto-Regressive (ARX) models. Results show that MR damper application reduces the possibility of chatter and improves the stability of boring operation.
