Abstract:
Present paper demonstrates the application of double disc magnetic abrasive finishing (DDMAF) process, on planar paramagnetic workpieces (copper alloy and stainless steel) of different mechanical properties like flow stress, hardness, shear modulus, etc. The copper alloy and stainless steel work pieces have been finished using DDMAF process. The experiments were performed based on a response surface methodology. The results obtained after finishing have been analyzed to determine the effect of different process parameters like working gap, rotational speed, percentage weight of abrasive, abrasive mesh size and feed rate for individual work material and to study various interaction effects that may significantly affect the finishing performance of the process. The outcomes of the analysis so obtained for the two different work materials have been critically compared to understand the effect of the considered process parameters based on mechanical properties. The scanning electron microscopy was also conducted on the work piece surface to understand the possible mechanism of material removal and the surface morphology produced.
