Abstract
ABSTRACT Since the invention of Magneto-rheological abrasive honing (MRAH), it is realized as one of the innovative ultra-precise surface finishing techniques employed for finishing of external intricate surfaces. In this technique, required level of finishing is achieved by assigning simultaneous rotation and reciprocating motion to the workpiece and magneto-rheological fluid, respectively. To recognize the surface finishing process, detailed understanding of material removal mechanism with consequences of various machining parameters on material removal (MR) is essential. Planned experiments (using response surface methodology) were conducted on the brass workpiece with varying rotational speed, finishing time, and magnetic field strength. ANOVA was employed to investigate the influence of chosen parameters on response. From experiments, rotational speed was detected as the most influencing parameter trailed by magnetizing current and finishing time. This paper presents material removal behavior and its mechanism in case of brass workpiece finished by MRAH process.
