Use of the electrorheological technique (ERT) for chatter control

A notable characteristic of an electro-rheological fluid (ERF) is its apparent variation in viscosity with the application of an electric field. The applications of this characteristic to the performance of controllable devices on vibration control of manufacturing systems are proposed here. It can be shown experimentally that by changing the applied electric field on an ER fluid, the machining chatter can be reduced remarkably.
