Abstract
A system for use in preparing an articulating surface of a component of an orthopaedic implant is provided. The system includes a magnetorheological polishing fluid including a carrier fluid and a plurality of particles suspendable in said carrier fluid. The system also includes a vessel for containing the Magnetorheological polishing fluid. The system also includes a mechanism for delivering the fluid to form a polishing zone and a holder for securing the component and for moveably positioning the articulating surface of the component relative to the polishing zone. The system further includes a controller for determining the rate of material removal from the object, for determining the direction and velocity of movement of the polishing zone relative to the object and for determining the number of cycles of polishing required.
