  Magnetic Field–Assisted Finishing Processes

11.1   INTRODUCTION

In these processes, the nature and strength of the bonding material used to hold the abrasives together determine the extent of mechanical abrasion process and, thus, the produced surface quality. Newly developed advanced finishing processes utilize magnetic field to control the finishing forces on the abrasive particles. The magnetic field–assisted processes include the following:

• Magnetic abrasive finishing (MAF)

• Magnetic float polishing (MFP)

• Magnetorheological finishing (MRF)

• Magnetorheological abrasive flow finishing (MRAFF)

11.2   MAGNETIC ABRASIVE FINISHING

Although MAF was originated in the United States during the 1940s, it was in the former USSR and Bulgaria that ...
