Summary
As abrasive machining is one of the suitable non-conventional machining processes. In the abrasive machining process, the main component is the abrasive particles. Shinmura et al (1990) developed a new finishing process in which magnetic abrasive was used as the cutting tool and surface roughness change that was obtained from 0.45pmRa to 0.04pmRa. Kansal et al (2007) made comparisons between the sintering process and mechanical alloying for the preparation of magnetic abrasives, experiments were conducted to check the surface finish change for both magnetic abrasive like mechanically alloyed magnetic abrasive and sintered magnetic abrasives, best results were obtained for mechanically alloyed magnetic abrasives with mesh size 52 and sintered magnetic abrasives with mesh size 130 and 180 comparable Technology and research developments in powder mixed electric discharge machining (PMEDM). Yamaguchi et al (2011) studied the effect of temperature in which changes of tools were used for magnetic abrasive finishing. Shinmura et al (1990) developed a new finishing process in which magnetic abrasive was used as the cutting tool and surface roughness change that was obtained from 0.45pmRa to 0.04pmRa. The maximum percentage improvement in surface roughness for different types of abrasive was respectively 18 % for mixed, 42 % for Adhesive based and 49 % for sintered magnetic abrasives. The surface Roughness of work piece was changed from 0.257μm to 0.075μm Ra in a machining time of 3 minutes with 220 grit size aluminium oxide. Teofilo et al (2006) stated that RSM is the mathematical and statistical techniques based on the fit empirical models Toward this objective, linear or square polynomial functions were employed to describe the system studied and, to explore (modelling and displacing) experimental conditions until its optimization
