PARAMETRIC OPTIMIZATION OF VIBRATION ASSISTED MAGNETIC ABRASIVE FINISHING PROCESS by Manjinder Singh

Abstract
Today’s market requires products or processes having higher efficiency, better quality, low cost along
with environment friendly. Finishing processes are divided into category’s viz. conventional and nonconventional processes. Magnetic Abrasive Finishing is one of the advance fine finishing processes that fall under the category of non-conventional machining processes. In the present research work, MAF process has been combined with mechanical vibrations to study the effect of vibrations on the surface finishing capabilities of the process. It is also known as Vibration Assisted Magnetic Abrasive Finishing (VAMAF). The varying value of acceleration combined with other effective parameters (rotational speed, time and abrasive size) was used to investigate the effect. Design of Experiment approach “Response Surface Methodology” was used to conduct and analyze the experiments for finishing aluminum flat plate with silicon abrasives, the optimized parameter values are rotational speed 650rpm, acceleration 11.84 m/s2, time 40 minutes, mesh number 200 and percentage improvement in surface roughness 56.85%.
