New magnetically assisted finishing method: material removal with magnetorheological fluid jet

It has been shown that a magnetically stabilized round jet of MR polishing fluid generates a reproducible material removal function (polishing spot) at a distance of several tens of centimeters from the nozzle. As a polishing technique, this unique tool resolves a challenging problem of high precision finishing of steep concave surfaces and cavities. Theoretical prerequisites and experimental results are discussed.
