Abstract
Magnetic abrasives play essential role in Magnetic assited abrasive Finishing (MAF) processes. The magnetic abrasives are prepared by a variety of technqies. In many existing applications of MAF simple mixing of ferromagnetic and abrasive particles has been employed. In the present work, the parametric studies have been conducted to assess the impact of prominent paramters of sintering process on perforamcne of magentic abrasives. The sintering time, concentration of abrasive and ferromagetic powder and compacting pressure were chosen as input paramters. Response Surface Methodology (RSM) has been used to conduct and analyse the experiemtnal work. Percentage Improvement in Surface Finish (PISF) is taken as perforamcne criteria. The optimal combination of input paramters was determined on the basis of experimental data. Sintering time of 24 min, compacting pressure 8.3 N/mm2 and abrasive concentration 18 % aluminium oxide with 82 % iron powder came as optimal combination.
