Proper functionality of devices and processes based on (MR) fluids greatly depends, along with other factors, on stability of fluid characteristics such as concentration of magnetic particles and magnetic properties of the particles. The concentratio

The effect of residual structure on properties of MR fluids, based on CI particles, was investigated using a magneto-sweep technique and initial magnetic susceptibility measurements. The shear rate, particle size, and the CI surface properties were a

One suitable way to polish optics of complex shapes is by using a jet of abrasive fluid. In doing so, the energy required for polishing is supplied by the radial spread of the jet, which impinges upon a surface to be polished. Generally, the jet inst

Conformal, freeform and steep concave optics represent important shapes that are difficult or impossible to finish using conventional techniques due to mechanical interferences and steep local slopes. One way to polish these optics is by using a jet

Magnetorheological finishing (MRF) is enabling technology that may produce surface accuracy of the order of 10 nm peak-to-valley and surface micro-roughness less than 10A. In this technique, magnetorheological fluid performs the primary function, whi

An original procedure and device used for the estimation of a sedimentation constant of magnetorheological fluids have been developed. Experiments that vary the volume concentration and particle size of the dispersed phase, as well as the viscosity o

A new, commercially available polishing process called magnetorheological fininshing is used to polish and figure precision optics. To understand and model this process correctly it is important to determine the mechanical properties of the fluid und
