Abstract
Finishing of a surface is the most important aspect for many industries and thus a lot of research has been going on in this area for decades. Many non conventional machining processes have been developed to get a more effective finished surface. One such surface finishing and polishing process is the Magnetic field assisted finishing process (MFAF process). It is best used to finish the free form surfaces. A Magneto-rheological fluid is used as a finishing medium in this process. The permanent magnet controls the rheological properties of the MR fluid. Finishing forces consist of normal forces which help in getting the required indentation and tangential forces which are responsible for the removal of the material through indentation. As magnetic flux density plays an important role in deciding the finishing forces in magnetic field assisted machining processes and to access the required magnetic field on the tool tip , a polishing tool is considered. In this study, an optimised finishing tool for MFAF process has been designed using a simulation software package (ANSYS) and then a critical analysis of variation of magnetic flux density at the tip of the tool for four different MR fluids is performed. Lord Corporation is a company that commercially manufactures these MR Fluids. The above analysis helps in determining the best MR fluid for further research in this vast field of finishing processes.
