The smart material so called magnetorheological (MR) fluid was applied in the study on vibration suppression of cylindrical turning. According to the framework of a common lathe CA6140, a shear type MR damper for turning vibration suppression was developed by designing its structure and magnetic circuit. Dynamic model of the turning system with the MR damper was set up and its effect of suppressing turning vibration was proved with simulation. Then, by optimizing the magnetic circuit of the damper based on finite element method, the area of the magnetic circuit decreased by 24% compared with that of the original design, it made the damper more compatible. Also, since the consumption of magnetic field in non-MR fluid region declined, the working efficiency of the damper was enhanced. Finally, the suppressing vibration test system was set up to verify the effect of the damper. It was shown that the MR damper can suppress the machining vibration apparently.
