Abstract

The magnetorheological finishing process uses a smart controllable-able fluid known as Magnetorheological polishing fluid, whose yield strength can be controlled externally by varying the magnetic field. The magnetorheological finishing process is capable of providing surface finishing up to the nano-level, but the precision finishing of non-ferromagnetic workpieces like copper and its alloys by using the magnetorheological finishing (MRF) process is challenging. Non-ferromagnetic material repels the applied magnetic field which results in the formation of only one magnetic pole at the tooltip. The magnetic pole at the workpiece surface is distorted by the repelling nature of the non-ferromagnetic materials. So, to finish the surface of nonferromagnetic materials, an axial force is needed to mitigate the repelling effect of nonmagnetic material. In this research paper, a new setup of the Extrusion Based Magnetorheological Finishing process has been designed which can provide the required axial force to the magnetorheological polishing fluid for the precision finishing of the non-ferromagnetic materials.
