Investigation of the Effective Parameters on Surface Roughness in Magnetic Abrasive Finishing Process Using Design of Experiments

In this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the SiC Abrasive slurry and Al2O3, use of diamond paste as abrasive tool) in Magnetic Abrasive Finishing process using designing of experiments on the external surface of Cylindrical work pieces of Stainless steel AISI 440C to get minimum surface roughness has been investigated. For implementation of tests, a mechanism was designed and after carrying out the tests, the obtained data was analyzed using Minitab software. Using response surface method the predicted model, the value of surface roughness was represented. Input parameters to produce optimum have also been reached using the predicted model and desirable surface roughness. Also, results show that the surface roughness has been improved by 50% with the working gap of 2 mm and work piece rotational speed of 355 rpm and using diamond paste.
