Introduction Finishing operations in the metal working industries are critical and an expensive phase of overall production processes. The application of magnetic field in the control of manufacturing processes in general and finishing in particular has become of interest. For example, magnetic abrasive flow machining, magnetic float polishing, magnetorheological abrasive flow finishing, and magnetic abrasive finishing (MAF) are some of such processes developed in the recent past [1]. Magnetic field assisted manufacturing processes are relatively new finishing processes and they are becoming popular in finishing, cleaning, deburrin
