Summary: In this study, a novel uniform flow restrictor was designed and developed for precise finishing of miniature gears using rotational magnetorheological fluid-based process. The impact of critical parameters on performance was analyzed through response surface methodology, resulting in improved surface roughness and texture after finishing. The use of different magnetorheological fluids with and without flow restrictors successfully removed manufacturing defects and achieved ultrafine surface roughness on SS316L miniature spur gears. Simulation of the forces involved in finishing gear profiles and a mathematical model for material removal during finishing were also carried out for a better understanding of the controlling mechanisms.
