Acidic magnetorheological finishing of infrared polycrystalline materials.
Chemical-vapor-deposited (CVD) ZnS is an example of a polycrystalline material that is difficult to polish smoothly via the magnetorheological finishing (MRF) technique. When MRF-polished, the internal infrastructure of the material tends to manifest on the surface as millimeter-sized "pebbles," and the surface roughness observed is considerably high. The fluid's parameters important to develop...
متن کاملFinishing of Optical Materials Using Fluid Jet Polishing
The characteristics of Fluid Jet Polishing (FJP), a newcomer in the field of optical fabrication, or more specifically optical finishing, are presented. Comments on the process possibilities are given, e.g. spot shape, process speed, and parameter dependencies. Preliminary results on a wide range of materials are discussed.
متن کاملMagnetorheological Finishing-A Deterministic Process for Optics Manufacturing
Finish polishing of optics with magnetic media has evolved extensively over the past decade. Of the approaches conceived during this time, the most recently developed process is called magnetorheological finishing (MRF). In MRF, a magnetic field stiffens a fluid suspension in contact with a workpiece. The workpiece is mounted on the rotating spindle of a computer-numerically-controlled (CNC) ma...
متن کاملPerformance Evaluation of Improved Ball End Magnetorheological Finishing Process
A novel nanofinishing process using improved ball end magnetorheological (MR) finishing tool was developed for finishing of flat as well as 3D surfaces of ferromagnetic and non ferromagnetic workpieces. In this process a magnetically controlled ball end of smart MR polishing fluid is generated at the tip surface of the tool which is used as a finishing medium and it is guided to follow the surf...
متن کاملNanoindentation hardness of particles used in magnetorheological finishing (MRF).
Knowledge of the hardness of abrasive particles that are used in polishing is a key to the fundamental understanding of the mechanisms of material removal. The magnetorheological-finishing process uses both magnetic and nonmagnetic abrasive particles during polishing. The nanohardnesses of the micrometer-sized magnetic carbonyl iron and nonmagnetic abrasive particles have been measured successf...
