Research on Material Removal Rate of Optical Glass Using MRF

摘要

A new optical machining technology―Magneto-rheological finishing (MRF) is researched. The polishing experiment about material removal efficiency is conducted through changing the polishing parameters such as magnetic field intensity, the density of polishing abrasive, relative speed and gap between the polishing wheel and the workpiece. The effect on the polishing character of optical glass by these parameters is analyzed on the basis of optical glass polishing mechanism and hydrodynamic mechanics.
