Abstract
Basic principle of detection of magnetic particle volume fraction in magnetorheological( MR) polishing fluid
which is based on mutual induction is analyzed
and corresponding prototype device is researched and fabricated.Relationship between output voltage and volume fraction of polishing fluid magnetic particle is linear
output voltage changes about 23.4 mV corresponding to 1 % magnetic particle volume fraction variation
and the result of measurement has nothing to do with flow.On-line detection of volume fraction of magnetic particle in common MR polishing fluid is realized
and it provides measurement basis for stable control of component of polishing fluid in MR polishing process.
