Abstract(#br)Abrasive flow machining (AFM) is a micro finishing methodology applied to achieve complex geometries which are not easy to obtain using other conventional techniques. AFM removes the material in form of small chips using abrasion mechanism. It gives good surface finishing but has a limitation of low material removal. To overcome the limitation, various hybridizations of AFM process have been developed. AFM process parameters such as pressure, velocity of media and temperature distribution on work piece play a major role in micro finishing. In order to enhance the AFM process capability, it is required to analyze the critical conditions of AFM process parameters using any commercially available software’s. Therefore, in present study, three dimensional modelling of the media flow path in abrasive flow machining was developed and analyzed to obtain the effect of the parameters using ANSYS® and Fluent® software. Further to overcome the major limitation of the AFM process that is low material removal, an experiment was conducted using abrasive media with carbon nano tube (CNT) and alumina. To enhance productivity, AFM process was optimized using Taguchi L 9 OA. Also, the work piece wear during AFM process obtained from the experiments was compared with Reye–Archard–Khrushchov wear law
