Electrochemo-magneto abrasive flow machine setup fabrication and experimental investigation of the process alongwith mathematical modeling and optimization

Abstract

In abrasive flow machining, there are two sets of piston-cylinder arrangements, i.e. machine and media. the machine ram pushes the media piston two and fro so that media filled inside it flows past the inner wall of workpiece and the material is removed. The extrusion pressure is the main mechanism of material removal. Various authors have made the process more effective in terms of material removal and surface roughness by providing rotational and magnetic force.

“…It has been concluded that this hybrid process gave material removal 0.17gm at 4 and 5 mm rod size and 0.125 gm at 6 mm rod size. It also found that silicone rubber-based media gave maximum MRR and polyborosiloxane gave less material removal as compared to other media [67].…”
