Magnetic field-assisted finishing  From Wikipedia, the free
encyclopedia Jump to: navigation, search  Magnetic field-
assisted finishing, sometimes called magnetic abrasive
finishing, is a surface finishing technique in which a magnetic
field is used to force abrasive particles against the target
surface.[1] As such, finishing of conventionally inaccessible
surfaces (e.g., the inside surface of a long curved pipe) is
possible. Magnetic field-assisted finishing (MAF) processes have
been developed for a wide variety of applications including the
manufacturing of medical components, fluid systems, optics, dies
and molds, electronic components, microelectromechanical
systems, and mechanical components.  History of MAF[edit]
Initially developed as a machining process in the US in the
1930s, with the first patent in the 1940s. University research
in the Soviet Union, Bulgaria, Germany, Poland, and US began in
the 1960s with practical usage appearing by the 1980s and
1990's. The growth of the semiconductor, aerospac
